Show HN: SubSmith – Turn your own videos into language-learning material
A
I've been learning Japanese for a few years and kept running into a similar problem. I'd find a video I wanted to learn from, hear a useful sentence, and then realise that turning that sentence into something I could study later was both time consuming and draining at times. I would end up jumping between a video player, subtitles/transcription, a dictionary, screenshots, audio clips and Anki. So I built SubSmith to bring that workflow together. You can drop a video or audio file into it, generate a transcript locally and then use the transcript alongside the media to: * look up words and sentences * replay individual lines * edit the transcript * save useful sentences with their original context/audio * export them as Anki cards The important part for me is that it works with your own media. It isn't tied to a particular streaming service or library, so I can use the random anime episode, podcast, lecture, etc. that I'm actually interested in studying. It's an offline-first desktop app, and transcription happens locally rather than sending the media to a transcription API. I'm sharing it here because I'm now more interested in finding out where this workflow breaks down for other people rather than adding features randomly now that I have solid core/base. For example: * Would you actually save sentences from your own media? * Which part of this process feels like too much work? * Does having the audio/context attached make creating an Anki card more useful? * Would you prefer this to work inside your existing video player/browser? * Is installing a desktop app a significant barrier? * And does requiring an account before starting the free trial make you give up? The current version does require an account to start the trial, and I'm trying to work out whether that's meaningful friction for the people who would actually use this. It's free to try, and I'd particularly appreciate feedback from people who already learn languages through their own videos, anime, films, podcasts or other media. I'm the developer, so I'll be around in the comments to answer questions and discuss how it works. https://subsmith.app

Show HN: Lathoa, a math app for kids where the AI is wrong on purpose
B
I made this for kids around 10 to 14. A robot called Errol solves a math problem step by step and one of the steps is wrong. The kid has to find it and say what's wrong with it. Sometimes nothing is wrong, so just saying "there's a mistake" every time doesn't work. The user needs to enter an explanation if she finds an error to gain more XP; speed matters also for more points. There is no direct interaction or chatting with an LLM. Lathoa's harness is stable and has many evaluation steps to catch inconsistencies and prompt injections. You can play one on the homepage without signing up. The part that surprised me: it's hard to get an LLM to be wrong on purpose. Half the time it gives you the right answer and calls it wrong, or a "mistake" that's actually correct. So every case gets checked before a kid sees it. Where it can, a plain arithmetic check redoes the math exactly. A second model also solves the problem without seeing Errol's work. If anything disagrees, the case is thrown away. The weak spot is that the second model can make the same mistake as the first. The arithmetic check is there for that, but it only works on English cases so far. German and Greek write decimals with a comma and I haven't got the parsing right yet. What I'd really like to know: does finding someone else's mistake teach anything that solving the problem yourself doesn't? I'm not sure, and I'd like to hear from people who teach.

Show HN: BraiNOTES, handwritten notes on your lecture PDFs in a browser tab
B
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!) 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. 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. You can try it here: https://notes.swimmingbrain.dev GitHub Repo: https://github.com/swimmingbrain/brainotes (MIT) 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. 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. 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. 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: Academa – Long-form STEM lecture videos generated by LLMs
C
Hi HN, we are Sina Atalay and Abdullah Geduk, co-founders of Academa. We are both PhD students. We thought: what if lecture videos were written as code and compiled into video using computer graphics and TTS? Then LLMs could write them, and lectures could be fixed with code edits instead of video production. On correctness: LLMs may make mistakes. But these videos are code sitting in our repository, and we can maintain them. Every report and review becomes a fix in the source, and everyone who watches after that gets the corrected lecture. Every recorded lecture on the internet is stuck with its mistakes. Ours will continuously improve. Each video also comes with an AI chat that understands everything said and shown in the lecture. There is a longer write-up at the bottom of the page. Happy to answer any questions.

Show HN: OnKey – I'm a bad singer, so I built an app to show where I'm off-key
C
Hi all I was pretty terrible at singing, now I’d say I’m bad but not terrible. This is because I’ve been using a singing app (won’t name it here) that scores me on my pitch and timing throughout the song so that I can improve. Lately however, the app I’ve been using has flooded their song list with songs that aren’t originals. I didn’t like this at all as for me, it’s easier to try to improve when you’re singing along to the original. So, I asked an agent (Claude Code) if it could write some code to listen to Spotify and also listen to me and see if it could detect both pitches and score me. It impressed me by writing some Python and showing me my pitch in the terminal! It couldn’t go all the way though and detect the singer’s pitch in real time. So I found the next best setup and built OnKey, a Mac app that needs to listen to the song once (it doesn’t save it) and then when it’s learnt the song (takes a couple of minutes), you can sing along to the pitch track that it’s learnt. OnKey is free to use and open source under the MIT license. It can listen to Spotify, Apple Music, and YouTube playing in your browser with the right permissions. During the build I found that someone had done something similar in Nightingale, but this requires a library of songs exported to disk and who has this in 2026 (maybe some of you ;) - but we need to help the normies too). You can check out a demo video on the site of me singing (warning given) here: https://singonkey.app The app sends out to find the song info (short Shazam fingerprint, and looks up song details), lyrics (from LRCLIB), and checks for updates. The app never sends the music (it doesn’t save this to disk) and your voice. Everything you’d expect to stay private does. It’s still weak in a few places: - when the song’s backing is noisy it’s hard to pick the pitch track out - sometimes it gets a note an octave off - it’s limited to Apple Silicon Macs, M1 or later, and only macOS 14.2 up because extra drivers aren’t required past this point - the scoring is built for beginners like me so it’s fairly easy on you Would love for people to try it out and let me know what works and what doesn’t for them!

Show HN: Build with Python – a beginner course where your code draws
C
Hi HN, I built this because I watched my daughter struggle at learning Python. I made something that runs only in the browser with visuals rather than relying on CLI/terminal output. No need to worry about python installation, package versions, venv etc. The lab runs with Pyodide in a web worker, and the program output is a picture by the side of the code block. A user would experiment with the code, and see the immediate changes in the visual output. The course has 13 modules, with the first 6 foundation modules free, module 7-13 with free readings but guide labs for a one-time price of $49. Please give it a try at https://scimigo.com/en/learn/build-with-python Send me feedback on the UX and on the exercise design, especially if you teach kids to program. I am also working on a C++ version for beginners (also with browser, no gcc or command lines). stay tuned.

Show HN: Uberblok – an interactive museum of ZFS internals
C
I've worked for a long time in the storage field during my career and ZFS is the piece of engineering I admire most in that space. I wanted a way to pay homage to it and to explore and better understand its internals. So I built Uberblok: a museum of ZFS. A deep dive into copy-on-write, txgs, vdevs, RAID-Z, snapshots, the ARC, metaslabs, the ZIL, send/receive with explanations and animated diagrams. I'm sure people here know these internals better than I do, so corrections are very welcome. I built it with my agent swarm organization, Algotitan. I hope you'll enjoy the deep dive into Uberblok as much as I do. Museum: https://uberblok.storagebits.workers.dev Repo: https://github.com/algotitanhq/uberblok

Show HN: A guided 3D Leonardo da Vinci museum, built in code
C
Hello HN, I am the founder of a small nonprofit which built Museum of Ages. We opened its first wing last week, a digital Leonardo da Vinci museum. It is a virtual tour with 17 stops, his works and then his last house in Amboise. The entrance is free. At the different stops you can see for example his paintings close to their real size, or 15 of his machines rebuilt in code, and you can have a look at 29 of his anatomy sheets. We also selected 207 of his manuscript pages which you can read in a virtual reading table, mirror the view to read his writing and 131 of the 207 are translated. We also rebuilt his last house in Amboise on the later stops of the walk. The museum is available in seven languages. Each stop has one of four grades as a label, documented, reconstructed, conjectural and not known. In a detailed view the user can have a closer look at the sources. The materials of the rooms and machines are created in Three.js. The museum runs with WebGPU. If the browser doesn’t support it, the fallback is WebGL2. To create the textures we used Creative Commons Zero photo scans (CC0) and for a few small objects we use free 3D models (CC0). Our mission is to create digital museums you can walk as not everyone can get to a museum, because illness or disability keeps them away. Some cannot afford the trip or just reside far away. So our goal is also to make our digital museums as accessible as possible. Therefore we also pre-rendered the walk so that it also works on older phones and is easy to use for older people. We released the code under AGPL-3.0. The texts and pictures are CC BY-SA 4.0. Reproductions have their own licenses. https://github.com/chipmates/museumofages We put a lot of time and passion into the museum and hope you like it. We are happy about any feedback. Which digital museum would you like to see next?
