Lector
Read real books in a new language, free and open source
What it does
Lector turns whatever you want to read into a language course. Import an EPUB, a web article, a YouTube video or a podcast. Every word shows its state: new, learning or known. Tap for a translation, save the word, then practise it as frequency-ordered cloze and push it to Anki. Fourteen language packs ship with an offline dictionary and a graded first-1,000-words series. Self-host it free under the AGPL, or let Lector Cloud host it from $0.
A self-hosted reader for language learners, with LingQ-style reading, Clozemaster-style cloze practice, and AnkiConnect integration. You keep your books and your data.
Read Turn any book into a lesson. Lector imports an EPUB file, an article you paste, or a page from a URL. It colours every word by how well you know it: new, learning, or known. For an instant translation on your device, click any word. For rare words, a large language model (LLM) does the translation. Listen Read along with video and audio. Paste a YouTube URL and choose a caption track. Lector imports the transcript, and every line keeps its timestamp. Click a line to move the player to that moment. Lector never downloads or hosts the video. You can also upload a podcast episode. A Whisper model transcribes it, and the current sentence highlights as the audio plays.

Link: https://www.nlpdemystified.org/ Hi HN: After a year of work, I've published my free NLP course. The course helps anyone who knows Python and a bit of math go from the basics to today's mainstream models and frameworks. I strive to balance theory and practice, so every module consists of detailed explanations and slides along with a Colab notebook putting the ideas into practice (in most modules). The notebooks cover how to accomplish everyday NLP tasks including extracting key information, document search, text similarity, text classification, finding topics in…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
