Show HN: Spotatui, a Spotify TUI/GUI without web API rate limits
About 11 months ago i revived the amazing but unfortunately unmaintained spotify-tui. Since then I have been working on it almost non stop, finding a lot of problems on the way.<p>One of the main issues I ran into were the Spotify web API rate limits. Third party clients like spotatui are dependent on a developer app made in the Spotify developer dashboard, which get rate limited a lot and Spotify has slowly been deprecating endpoints from it. The workaround for this used to be using a shared client id from ncspot but unfortunately that got rate limited too. This is when i started adding other playback sources, including YouTube, Navidrome/Subsonic, Internet radio with +- 30.000 stations, local files, Qobuz for lossless audio and Apple Music for macOS only where it controls the music app remotely.<p>I fixed both the deprecated endpoints and the rate limits with one solution. It still uses librespot in the back, my spotatui specific fork, but gets all data from it instead of only playback. The data comes from the internal API of the official clients, that API gives metadata, playlists, the user library, devices, lyrics and audio analysis. For searching it uses Pathfinder, the internal GraphQL API.<p>There are no web API rate limits because there is no shared app quota. Every user uses their own session as if it was the official client. The only potential problem is that Spotify does not document this API so any change on their side would break it. I intend to fix any of those issues as soon as they pop up.<p>It all started as a TUI back in 2019 but since then I've added a GUI to it too. The GUI is still a bit behind the TUI in terms of features, it only ships Spotify for now, but full parity between the TUI and GUI is coming soon. After that full parity with the official client is next. That is also why I made the GUI looks almost the same as the official client. That way its easier for me and users to find missing features.<p>Spotatui also has lua scripting support, a optional Web companion on spotatui.com, and if you have a AI coding agent like ChatGPT codex or Claude Code you can enable the MCP tools, which lets AI become your personal DJ just by talking to it.<p>Its written in Rust, uses ratatui for the terminal UI and Tauri 2 for the GUI. The Rust core starts a small web server with localhost that only your pc can reach which the GUI then serves. Both frontends share the same playback logic, the same login and the same Spotify code. The only difference is how you interact with it.<p>On first launch it opens a web browser where you need to login with your Spotify premium account (premium is not optional), that is the whole setup done. I would love any feedback about bugs you encounter or features you would like to see.

Show HN: XY Music Notation
I've been playing around with a new kind of isomorphic music keyboard that uses a base-12 notation, and wanted some sheet music to learn some new music for it.<p>The idea is to represent each note in 12-TET as a number, so N ∈ (0,1,2,3,4,5,6,7,8,9,X,Y).<p>I used codex to build a music score rendering backend based on MuseScore with custom note heads that display the pitch class of each note.<p>I've found it pretty helpful for learning how to play my own instrument, so wanted to share in case anyone else was interested.

Show HN: Guitoro, a virtual guitar you strum with your keyboard
Guitoro is a free browser guitar using recordings of real instruments. You can strum with your keyboard, mouse, or touchscreen, choose acoustic, classical, electric guitar or bass, and see chord fingering and each stroke. Song practice can be slowed to 20%, and there are free chord tools and tuners. No signup or download.<p>1 minute video demo: <a href="https://youtu.be/DtcluMLdSgs" rel="nofollow">https://youtu.be/DtcluMLdSgs</a><p>I would love feedback on how the strumming feels and sounds.

Show HN: BraiNOTES, handwritten notes on your lecture PDFs in a browser tab
In August, I posted here about TeXbrain, a LaTeX editor that runs completely in the browser, with no need for an account or server. (I didn't excpect it to get that much feedback, bug reports and help from here!)<p>This is the same idea for the other half of my studies, the handwritten notes. I take them on a convertible laptop, and I've had a hard time with apps for that, taking notes from a device to another, exporting as PDF, needing an account for many of them, etc. So I've been working on the version of it that I always wanted. Open a tab, the slides of the lecture or multiple PDFs open next to the page or even become the page, write on them with my pen, and nothing ever leaves my browser.<p>braiNOTES is a static website and has no backend. Strokes are perfect-freehand outlines which support pen pressure, the PDF files are rendered by pdf.js in a worker, and for storage it uses IndexedDB a moment after every change. No account, no analytics, and completely offline and local-first. You can export notebooks as .brainotes files, which in the background is a zip with one json per page + the PDFs and pictures you import. It keeps the original pages and puts the vectorized ink on top, this way the text stays selectable in the slides.<p>You can try it here: <a href="https://notes.swimmingbrain.dev" rel="nofollow">https://notes.swimmingbrain.dev</a>
GitHub Repo: <a href="https://github.com/swimmingbrain/brainotes" rel="nofollow">https://github.com/swimmingbrain/brainotes</a> (MIT)<p>In Study mode, the PDF opens on the side of the tab, you can read it simultaneously to the notes, snip a formula or diagrams directly into the notes with the snip tool, and then write around it. In Board mode, you have just a Whiteboard for tutoring or simply for more place for exercises, and can also highlight or draw things with the laser pointer tool while presenting.<p>The line of the ink appears the moment the pen moves, and a one euro filter calms shaky hands while you write + a light a refit when you lift the pen.<p>I also have a video editor and an animation tool which are still a work in progress, on the same GitHub profile. I'm also working on a MCP server for each tool, so you can use your MCP client to do further things with your notes, automatically edit videos on the video editor, etc. That feature will of course be off unless you turn it on and will only be able to talk to localhost.<p>I've used this tool for every lecture in the last few months and a few friends use it too. Bug reports, fixes, recommendations, feedback are all welcome!
Show HN: Atticus – Hold-to-talk voice assistant for macOS that runs on Claude -p
Hi HN! I'm Saarth. I'm in 9th grade, and I built Atticus.<p>Atticus is a fast and cheap Mac assistant that can do tasks for you. You hold down Control-Option-Space, speak or type your task, be it complex or a simple browser search, and Atticus will get on it.<p>The interesting part is that simple tasks, like opening apps, playing a Spotify playlist, or web queries, don't touch AI, and instead are processed locally and typically finish in under a second. For example, prompting Atticus to open apps takes around 0.08 seconds, sometimes even finishing before you finish your sentence, sort of like Jev.<p>Any tasks that are more complicated will be sent to Claude via claude -p, meaning you never need an API key and Atticus will run on your existing Claude Pro or Max plan. By using this approach, costs are also cut down immensely, with, on average, tasks costing a fraction of a cent.<p>To achieve Atticus' speed, it remembers shortcuts from each task it completes. When it does a task right for the first time, it saves its steps and replays them the next time without AI. For example, a workflow of creating a new meeting took about 30 seconds the first time around. Atticus then logs the exact steps to memory and takes 5-8 seconds on the next pass. To add to this, Atticus also learns about you as you use it more and from what's on your computer, including your name, your apps, and things you want it to remember, personalizing its answers to you.<p>To combat the safety concerns over giving an AI unrestricted access to your device, Atticus has toggleable restrictions, so before anything is deleted, sent, bought, or written to a file, the user is prompted before that action.<p>Some features I'm currently working on include a meeting copilot that capitalizes on Atticus' speed, allowing Atticus to listen in on meetings and answer questions in real time as they come in, personalized to the context of the meeting and what it knows about you.<p>To run Atticus, macOS 26 or higher is required for its voice transcription features. The voice transcription is also done locally by macOS.<p>Atticus is free, open source, and also very fresh, and I'm completely aware of its many rough edges, which is why I'd love to hear from everyone about what breaks and what you guys would like to see Atticus do!

Show HN: Opus 5.5 made a fully featured Figma clone in 3 hours / 8 prompts
I think a chasm has been crossed. Opus 5.5 few shotted a fully working Figma for me. In the past year I have been trying to benchmark vibe coded apps and see how good they get and this week it did it with very very little guidance from me. I basically just told it reach feature parity.<p>Prior to this vibe coded apps would resemble the real software, this is not a resemblance it's the real thing. As a casual Figma user in the past, I can't really see a difference. And if there is one you have an LLM that can on the fly operate the app or use it.<p>P.S. I did this is on Mana which is our startup making it easier for LLMs to do it (probably the code is half of what would have been and there are primitives it can use but ultimately it's a testament to how good models have gotten). I went on to make google meets, docs, telegram, linear, etc. All basically with single prompts. The biggest jump has been in the UX understanding of models and attention to detail.
