[Megathread] The App Pile - June, 2026

SCIWAND: Read, analyse and write - with every answer traceable to a sentence in your own PDFs. Problem If you do serious reading - research, law, due diligence, lit reviews - you end up with a pile of PDFs and a stack of tools that don't talk to each other. General AI chatbots almost useless: they hallucinate, can't see your actual library, and upload everything to someone's cloud. You still can't ask one question across 200 documents and trust the answer. What Sciwand does Sciwand is a local-first desktop app (macOS/Windows/Linux) that sits on top of your document library - PDFs, Word, EPUB, plain text. Also connects to many scientific databases as Google Scholar, Pubmed etc. You can: Ask a question across your whole library and get a grid of answers, every cell linked to the exact highlighted sentence in the source PDF (click a citation → it opens the PDF at that line). Screen hundreds of documents against criteria (free-text / yes-no / 1–10 scores), each verdict cited. Write in a Markdown editor with an AI sidebar that quotes only your sources. Search 10 academic databases (Google Scholar, PubMed, arXiv, Semantic Scholar…) and sync with Zotero, Mendeley, EndNote & Bookends. Comparison vs Notebook LM: can do library chat but in a linear single chat interface. Poor citation (links to extracted text). Sciwand allows the same plus ability to generate AI response into columns/tables. Citations link to highlighted paragraphs in PDFs. Ability to search academic DB from within the app. Also has an AI writer that links to your library, without the open web hallucination. vs. AI writers like Jenni.ai: they generate prose and bolt on citations that may not exist. Sciwand grounds every claim in your library and lets you jump to the exact sentence - zero fabricated references. vs. literature-graph tools (Research Rabbit, Connected Papers, Litmaps): you get a live citation graph plus the PDFs and AI one click away, so reading, analysing and writing happen in one app instead of three. vs. cloud "chat with PDF" tools (ChatPDF, Elicit, SciSpace): Sciwand is local-first. You own your data. There's no subscription. You bring your own AI key, so you control the model and the cost. Pricing All app features are free (lifetime) including manual columns, academic database searching, markdown writer, citations. AI features are available as a 7 day demo with the option to purchase a life time license. One device from $39.99 Students & faculty get a 20% education discount. 👉 https://sciwand.com

AppAtlas 1.x – a local Mac app catalog for people with too many apps 100% Free! DE/EN This is a purely personal/private project that I’m only sharing here. The GitHub repo is in German, so please use Google Translate or similar if needed — I speak German myself. I’ve been collecting Mac apps for years – from the App Store, GitHub, BundleHunt, StackSocial, and Reddit. At some point you lose track. AppAtlas is my solution. The app scans local folders, automatically fetches icons and descriptions from multiple sources, translates foreign-language text locally, and stores everything privately on your Mac. No subscription, no account, no cloud. Highlights: **•** **Scan folders, categorize apps, store license data in the Keychain** **•** **Fetch missing metadata from the App Store, GitHub, Reddit, and websites** **•** **Review uncertain matches before they’re applied** **•** **Themes, multiple layouts, JSON export with optional AES-256-GCM encryption** **•** **Liquid Glass effects for sidebar, cards, and controls on macOS 26, fully compatible from macOS 14** **•** **Completely free, open source (GPL-3.0)** Feedback very welcome — especially on the automatic metadata detection, which isn’t perfect yet. 👉 https://github.com/Schrotty74/AppAtlas/

CleanCut + PolishKey Full disclosure: I built both of these. They're small Mac utilities, not giant suites. CleanCut Problem: A video is often almost usable, but one thing blocks it. Maybe it needs curse words muted before sending to a parent, student, or client. Maybe it needs subtitles. Maybe the file is some weird MOV/codec combo that plays fine on one machine and then causes player or transcoding issues somewhere else. CleanCut is meant for that cleanup pass. You can run any of the three jobs by itself, or stack them in one run: - mute curse words - generate subtitles for a video that does not have them - convert/remux to a universal MP4 It runs locally on the Mac, so the video does not get uploaded just to caption it or clean the audio. Comparison: HandBrake/ffmpeg are great for conversion, but they do not handle profanity muting and subtitle generation in the same simple flow. Descript and cloud caption tools are more full editing suites, and I did not want to upload videos for this. Tdarr is great for libraries and automation. CleanCut is more for one-off files before sharing, archiving, or importing. Pricing: First 3 completed videos are free, then $19.99 one-time lifetime. https://envelopesapp.github.io/tools-site/ PolishKey Problem: I kept writing rough emails, Reddit replies, product notes, and support messages, then pasting them into a browser just to make them sound cleaner. PolishKey lets you highlight text on the Mac, press a shortcut, pick a tone, and replace it with a cleaner version. The point is speed: fix the writing where you already are. Comparison: Grammarly and Wordtune are useful, but they feel more like subscription/editor tools. ChatGPT and Claude are flexible, but for a quick rewrite the copy/paste loop gets old. Pricing: 25 rewrites are free, then $19.99 one-time lifetime. https://envelopesapp.github.io/tools-site/polishkey.html

!nvoker: Make every text field smarter! Problem: I am a software engineer and built !nvoker because I wanted a faster way to rewrite text on Mac without breaking flow or adding another AI subscription. !nvoker is a native macOS command palette for text transformations. It includes built-in commands like improve, shorten, summarize, formal, friendly, and translate, etc It also lets you create your own custom commands for prompts you use often. It works with your own API key and currently supports the latest models from ChatGPT, Claude, and Gemini. Get started with gemini flash right away. The workflow is simple: select text, press Command-Shift-!, choose a command from !nvoker, review updated text and hit enter to replace. Comparison: Compared with ChatGPT or Claude in a browser, !nvoker is better for quick repeated writing tasks because you stay in your workflow instead of jumping between tabs and apps. Compared with Raycast AI and similar subscription-based tools, !nvoker is a one-time purchase and BYOK. You bring your own provider key, keep control over your setup, and avoid another recurring fee. Pricing: $12.99 one-time, Link: https://www.simbafy.com/invoker I built this because I genuinely needed it in my own workflow and spent a lot of time refining it to feel fast, simple, and native on macOS. I am already working on updates to make it even better, including things like an inline editor. Happy to answer questions or get honest feedback. P.S. invoker is my favorite hero from dota2.

Informity AI Free local document chat for Mac with source citations and full privacy Problem Every AI document tool requires uploading your files to a cloud server. For anyone with sensitive documents — work files, research, client records — that's not an option. I wanted to ask questions across my own documents without the data leaving my machine. Comparison Unlike ChatGPT, NotebookLM, or AnythingLLM, Informity AI runs entirely on your Mac with no cloud uploads, no account required, and no usage limits. It indexes your entire document library once and lets you query across all of it instantly with citations back to the exact source file. Supports PDF, Word, Excel, PowerPoint, EPUB, Markdown and more, with Ollama integration for custom model setups. Pricing Free. No trial, no subscription, no in-app purchases. MIT licensed and fully open source. https://www.informity.ai | https://github.com/informity/informity-ai

RTFM Player An audiophile music file player and librarian for macOS that supports multiple libraries and bit-perfect playback Problem I built RTFM Player because I couldn't find another music file player for macOS that met all of the following criteria: most important: support for multiple, discrete libraries with their own artwork grid mental model and interface based on the user's own file and folder structure minimalist, modern design support for lossless FLAC, ALAC, and DSD (and all other significant lossless and lossy audio formats) bit-perfect playback via sample rate and bit depth matching and ability to take exclusive control of the audio device extended metadata editing of single tracks or multiple tracks ability to export and import the database and artwork cache for easy migration or backup lightweight on CPU and RAM, small installer (only 18 MB as of the current version) no feature bloat: the app is simply for quickly organizing, locating, and playing music files in a way that's resembles grabbing your favorite CD or LP and playing it back at the highest quality has a 30-day free trial for evaluation and then a one-time price (not a subscription) for a user license to install on multiple computers official release signed and notarized by Apple via the Developer Program Comparison Swinsian: I'm a big fan of Swinsian music player and have been using it for over 5 years because it's great, but it is heavily tied to the iTunes / Apple Music, single-library mental model. RTFM Player allows you to completely segregate your lower quality mp3 collection from your FLAC collection by putting them in their own libraries. That way when you click on your FLAC library the UI/UX completely switches over without the need to filter down. Another scenario that RTFM Player handles better thanks to multiple library support is the ability to separate music collections based around singles from album collections. This is essential if you're a DJ or otherwise have folders filled with singles. Without their own separate library a folder filled with singles will add hundreds or thousands of "albums" to your album view that only contain one or two songs. For listeners who like to browse and listen to whole albums this isn't acceptable. Separating libraries with singles from those with albums is the solution. Audirvana: I love the look of Audirvana but I'm much less a fan of its high price, I don't need to link streaming platforms, and am not interested in plugins and signal processing. RTFM Player gives you a much simpler, lower cost, but still beautiful looking interface that is designed to be a bit-perfect source, much like dropping a CD into a high-end transport and sending the audio to a fancy DAC. Think of RTFM Player like the high-end transport sending a pure signal to your DAC that's nice to look at, like Audirvana. Pricing The current price is $29.99 for a license that grants a single user rights to install RTFM Player on up to 5 computers that they own. Since the app is technically in beta and in need of some additional testing, the price could be free to first adopters who provide valuable feedback that makes it into an update. I will also put the names of all beta testers in the acknowledgments section of the license splash screen forever, so if you want to join the hall of fame please DM me 😄. RTFM Player can be downloaded from rtfmdesign (dot) com.

Tough crowd in here! This represents 600 hours of work over the past couple of months (yes, 12+ hour days).

u/Mstormer - I want to make sure I understand the sub rules because I may have misunderstood. My product website has a privacy policy and terms and conditions. I also went through the KYC verification process with the merchant account FastSpring and was approved. I'm a member of the Apple Developer Program and the app is signed and notarized. I could have posted my LinkedIn profile and email address, although currently my LinkedIn profile lists my 25 year job history in I.T., branding, music, and media production. I haven't added RTFM Design to my working history yet because I'm 9 months in and trying to figure out what I'm doing next with my career. It may end up being software development. Do I qualify for Tier 2 in the rules, and thus could have (or still could) post my app in the main thread? I put hundreds of hours into this project and the Megathread is proving to be a sad way to announce it to the world because I've gotten zero feedback.

Tomo – a native macOS e-book library manager (Calibre alternative) Problem For people who want to own their books and send them to their Kindle or Kobo over USB — no lock-in, no Amazon servers, no accounts. Tomo is local-first and privacy conscious. Comparison Calibre is the benchmark. I've used it for years. It works, it's powerful and stable. I just never enjoyed opening it. Tomo does maybe 5% of what Calibre does: Manage a library of EPUB and PDF Open and read these formats Edit metadata, swap covers (Open Library / Google Books lookup) Send to Kindle (in-app EPUB → AZW3 conversion) and Kobo over USB Detect language variants (pt-PT vs pt-BR, en-GB vs en-US, etc.) on import Search external catalogues via small JS plugins (Gutenberg ships through a registry) But it looks and feels good while doing it. Pricing Free, no account, no servers, macOS 26+. https://tomolibrary.com -- Disclaimer: I'm a developer but I don't know Swift. With AI I can now ship native Mac apps too, so I did. The product, design, architecture, and on-disk contract are mine; the SwiftUI is mostly Claude output. you can check the source code at https://github.com/pdrbrnd/tomo

This is one of the clearer pitches in this thread. The “5% of Calibre, but pleasant to use” positioning makes sense to me. Calibre is incredibly capable, but I also avoid opening it unless I really have to. One thing I’d want to know before switching: how does Tomo handle a larger existing library, say 1,000+ EPUB/PDF files with messy metadata and covers? If the intended use case is smaller personal libraries rather than full Calibre replacement, I think saying that explicitly would make the positioning even stronger.

App Name: TaskOptimist for iOS & MacOS - a personal project management app. Problem: simple to use but fully featured personal project management app Comparison: MS Project / MS Planner, this is cheaper and is more tailored to simple personal projects although is still fully featured (auto scheduler, dependencies, task hierarchies, due dates, gantt chart, agenda, calendar, categories) Pricing: Free (with max three projects & 100 tasks), $1.99 for pro (coming soon). https://apps.apple.com/gb/app/task-optimist/id6751349703 (includes a video preview) I intend to always have an ad free no money version. Feedback would be great. Thank you www.TaskOptimist.com (Android users, dm with your email and I'll have Google Play send you a link, Windows coming very soon).

While everybody around are crazy coding AI agents, I found myself in dilemma -- the official whatsapp clients are ugly and bloated, unfortunately I need to communicate with people over this messenger. So I did mine, based on opensource whatsapp client library. Probably nobody needs it. Features QR-based device pairing (multi-device protocol) Text, image, and file messaging — 1:1 and groups Drag-and-drop / multi-select attachments — staged with previews + a caption before sending Push-and-hold voice notes (Opus/PTT, slide-up to cancel) Reactions, reply / quote, edit, revoke, delete-for-me Forward messages (single or multi-select) to another chat Star messages (⌘S) Pin chats — pinned section at the top of the sidebar Pin messages in chat — banner above the conversation, jump on tap Add to contacts / edit name — synced to the phone address book Archive chats (collapsible Archived section) and delete chats — synced; deletes stay deleted across restarts Block / unblock contacts — blocked banner, sidebar indicator, Settings list Leave groups Right-click message menu with quick-reaction strip; sidebar + conversation-header action menus Shortcuts: double-click to edit/reply, ↑ to recall last own message On-device translation via LLM Chat inspector: contact About text, starred messages, shared media grid, files list — click any item to jump to its message Read receipts, typing indicators, presence Peer-device sync (edits / delete-for-me / star / pin) via appstate + SecretEncrypted History sync, macOS native notifications (and more, more, more!) Opensource and free, install via brew. brew tap vadika/yawac https://github.com/vadika/yawac brew install --cask vadika/yawac/yawac github -- https://github.com/vadika/yawac

PopNote — floating bubble reminders for macOS I just launched PopNote, a small macOS menu bar app that turns quick reminders into colorful floating bubble notes on your desktop. Write a reminder, choose when it should appear, and it pops up when you need it instead of disappearing into Notification Center. Features: Floating bubble notes Menu bar access Apple Reminders integration Repeat options Light/dark mode Bubble colors + simple icons Link: https://quietware.itch.io/popnote

i m here to find gems, will update my reply based on what i like

Hitoku v1.6, open-source local macOS context aware assistant with Qwen3.5/Gemma4 - $5 Hi all, I posted the app here a couple of months ago, and got lots of feedback from a few users. So, I have been working on improving it and open sourced it. I stripped a few things, and implemented a bunch of new stuff. Note, it is still in experimentation. Description: I've been building Hitoku. An open-source, voice-first AI assistant that runs entirely locally. No cloud models, nothing leaves your machine. Problem: I write a lot, and copy-pasting text into a browser just to get LLM drafting is exhausting. Because I handle sensitive information, I needed something that works entirely locally, privately, and easily. I also read lots of academic papers and sometimes I need a quick info, and want to do this without internet. What’s new: Currently, it supports Gemma 4 and Qwen 3.5 for text generation, plus multiple STT backends (Parakeet, Whisper, Qwen3-ASR). You can add your own LLMs, but I decided to make a few good ones already available. Tool use, such as create calendar events, or use web search. Existing feats: It's context-aware; it reads your screen, documents, and active app to understand what you're working on. You can ask e.g. about PDFs, reply to emails. Examples: - query a pdf document, https://www.youtube.com/watch?v=ggaDhut7FnU - reply to email, https://www.youtube.com/watch?v=QFnHXMBp1gA - and with ctrl+S is just voice dictation (with optional polishing) I currently use it a lot with Claude Code, Obsidian, notes, as well as to read papers, or to some write emails (where I do not need to provide context, as it understands alone). Code: https://github.com/Saladino93/hitokudraft/tree/litert, and you can compile this yourself Download bundle: https://hitoku.me/draft/ (free with code HITOKULANG, valid for 50 downloads) Pricing: $5, otherwise you can compile from the source code! Changelog: https://hitoku.me/docs/hitokudraft/changelog Developer disclosure: Sole developer Personal side project Open-source No tracking / no telemetry (internet connection is only software updates, and eventual web search) AI Disclaimer: None

Hourglass Timer - an aesthetic, simple timer for focused sessions I built an Hourglass Timer, a free little macOS app for writing sprints, focus sessions, and quiet work. It’s a visual timer with 6 color themes, an always-on-top mode so you can keep it visible while writing or working in other apps, and brown, pink, and white noise that plays as the sand pours. I wanted something calmer than a regular countdown timer. Something more aesthetic, less stressful, and a little ritual-like. It’s free on itch.io right now, with versions for both Apple Silicon and Intel Macs. This is the first app in my Quietware collection: small, soft utility tools for focus and creativity. I’d love feedback, especially from writers, students, devs, or anyone who likes cozy productivity tools. Also, if you have any productivity or aesthetic app ideas, throw them my way. I might just make it.

Splashy – Automatic Unsplash wallpaper rotation for macOS Problem macOS ships with a handful of static, albeit gorgeous wallpapers and a basic auto-rotate from a local folder. If you want fresh, high-quality photography on your desktop without manually downloading anything, there's no good native option. Comparison Unsplash itself has a desktop app, but it gives you no control over sources and has not been updated in 7 years. Plus, it just picks randomly from a few topics. Splashy lets you define exactly what you want: specific collections, topics, search queries, or photographers, each with their own time-of-day schedule. Features Import Unsplash collections, topics, search queries, or follow specific photographers as wallpaper sources Time-of-day scheduling per source like "coffee" shots in the morning, a dark OLED collection at night Menu bar app, stays out of the way, but also a sleek UI (in my opinion) Pricing Free. Early release and feedback very welcome!! github.com/Halfaxas/Splashy https://halfaxas.github.io/Splashy/

Hi again, I know I am much later than I said I would be after posting a post that became very popular & this post I was going to message everyone privately, however, across 2 posts it was a lot of people. So decided to do the approach differently. ---- Glintype is now officially out for everyone to try. Description: Glintype is a macOS local-first autocomplete app that brings fast, system-wide text suggestions across the apps you already use. Go through the setup once, and it lives in your menu bar. Your words never leave your computer. There is no telemetry, no tracking, nothing. It is built to be local-first, with support for local models, Apple Intelligence where available, and optional bring-your-own-key cloud mode for people who want it. Problem: The main problem this app solves is the subscription model out there for this type of app. We think a one-time fee is fair. Glintype aims to make autocomplete feel native across macOS and to remember your writing style and use it for all future recommendations. Compare: Unlike other apps in the field that pivoted to a subscription model, we decided to opt for a one-time payment for lifetime access to the app. To all future updates regardless if it's a minor or a major upgrade. We offer Apple Intelligence, a variety of local models and the ability to bring your own .gguf and BYOK Cloud models. Also, unlike other apps that have some features on higher plans or in "beta", we include app profiles, dictionary replacements, emoji shortcuts, autocorrect-style fixes, visual/OCR context where enabled, and compatibility handling for native apps, browsers, and web text fields as standard. Privacy: Glintype is local-first. Your writing stays on your Mac unless you explicitly enable cloud or hybrid mode. Local models run on-device. Pricing: Free 7 days trial included. After the trial, Glintype is a one-time lifetime purchase - no subscription. Launch price(ends June 19th): $18 (After launch will be $30) (Sale ends on June 11th) Website: https://glintype.app Changelog / Launch build: Recent work includes better caret placement, improved emoji :shortcode detection and general improvements. Next build will focus on fixing bug reports that flow in from users, fix some more specific app compatibility, and general QoL updates. Note: The trial period is to try and iron out the bugs from a vast number of users at the same time. If there are more bugs than I noticed, the trial period will be extended to allow sufficient time to fix all of them. (Of course, you are more than welcome to buy to support the development at any time) You may email the support email in the settings, DM on reddit or Twitter for any bugs.

**LiveWall** — Turn any 4K video into a live macOS wallpaper **Problem:** Every existing live wallpaper app on macOS either locks 4K behind a $10+/month subscription, crashes constantly, or requires complex setup. Mac users who want animated/video wallpapers have no good native, lightweight, free option. **Comparison:** - *Wallpaper Engine* (Steam) — Windows-first, $3.99 but limited macOS version, no lock screen support - *HiDock / Dynamic Wallpaper* apps — limited to pre-made content, no custom video upload - LiveWall lets you drag & drop ANY 4K video, supports per-display wallpapers (different video on each screen), renders on the lock screen, and auto-pauses on battery. It’s native macOS — no Electron, no subscription wall. **Pricing:** Free to try — https://livewall.astitwa.ai/ (Disclosure: I am the developer)

LectureSync – a native macOS app that records lectures and turns them into trustworthy study notes Problem I have two kids in college, and I kept having the same thought: there has to be a better way to do this. You sit through an hour of lecture trying to write fast enough to keep up, and you still walk out with half of it. I wanted something that captured the lecture properly and turned it into notes you could actually study from, without sending any of it to someone else's servers. LectureSync is local-first and runs fully on-device on Apple Silicon. No account, no upload, works offline. Comparison There are good tools out there for this. Otter, MacWhisper, and others do solid transcription, and honestly transcription is a mostly solved problem now. LectureSync is built around the part that comes after the transcript: Generates notes and study guides from the lecture, with a faithfulness check that ties what you read back to what was actually said Keeps every run of the notes step as a separate version. Local models don't give you the same notes twice, so you can generate a few takes, page through them, and keep the best one. Nothing gets overwritten. A different notes model per course, so you can tune the generation step for a dense subject vs. one where you just want clean summaries. Every run is kept as a version, so trying a different model or a second take never costs you the notes you already have. A study assistant that points you to the part of the lecture where the answer lives, instead of just handing you the answer Makes flip cards from the lecture, each backed by a word-for-word quote from the transcript, with a play button that jumps to the moment your professor said it. Cards the transcript can't back up get dropped. Review comes back on a spaced schedule, so you see a card right before you'd forget it. Crash-safe audio capture, so a dead battery or a crash 40 minutes in still leaves you with usable audio. Pause and resume, crash recovery on next launch, and a second confirmation before discarding On-device readability and language passes, speaker labeling with clickable timestamps, auto-detected lecture titles Pulls the audio straight out of video files, so a recorded lecture or a screen capture goes through the same notes pipeline Imports existing transcript files (VTT, SRT, TXT, PDF, more) and Voice Memos, reusing a transcript when one already exists The thing I've put the most work into is keeping the generated notes honest. That's the whole reason I built it. Pricing Going to be $9.99 at launch. Right now I'm looking for free TestFlight users to help shake it out, so it's free if you want to jump in and give feedback. macOS 26+, Apple Silicon. https://lecturesync.app I'm a solo developer building this around a full-time job. The product, the design, and the architecture are mine. Claude wrote most of the SwiftUI. The part I put the real hours into was the notes quality: I ran extensive model testing on an RTX 3090 + 3060 rig to pick the models that do this job best, then ran the app itself on my MacBook Pro M1 Max (32GB) to make sure it holds up. I keep test harnesses around the notes engine so it stays faithful to the lecture.
