Yapit – PDF and webpage reader with TTS that doesn't suck
Yapit converts PDFs and web pages to audio, with a vision-LLM pipeline that handles math and complex layout instead of garbling them. I built it because I read a lot of papers and content online, but drift off after two paragraphs. Listening while following along keeps me focused and lowers the bar to actually start. Every TTS tool I tried broke on complex formatting. Papers with math, citations, figure references, page numbers in the middle of sentences. You either get garbled output or you're listening to raw LaTeX. Yapit converts everything to markdown as a common format. For web pages,…
What it does
In the maker’s words, at launch
Yapit converts PDFs and web pages to audio, with a vision-LLM pipeline that handles math and complex layout instead of garbling them. I built it because I read a lot of papers and content online, but drift off after two paragraphs. Listening while following along keeps me focused and lowers the bar to actually start. Every TTS tool I tried broke on complex formatting. Papers with math, citations, figure references, page numbers in the middle of sentences. You either get garbled output or you're listening to raw LaTeX. Yapit converts everything to markdown as a common format. For web pages, defuddle (https://github.com/kepano/defuddle) handles the extraction and strips clutter from web pages, presenting the main article content in a clean, consistent format. For PDFs, a vision LLM rewrites each page into markdown with annotation tags that separate what you see from what gets read aloud. Math is rendered visually but gets spoken alt text. Citations like "[13]" or "(Schmidhuber, 1970)" are silently displayed. Page numbers and headers are removed entirely. Both extraction and audio are cached by content hash, so the same content is never processed or synthesized twice. Self-hosting works with any OpenAI-compatible TTS server (vLLM-Omni, ...) and any OpenAI-compatible vision model for PDF extraction: git clone --depth 1 https://github.com/yapit-tts/yapit.git && cd yapit cp .env.selfhost.example .env.selfhost make self-host Kokoro TTS also runs in the browser via WebGPU on desktop. Try it on Attention Is All You Need (all voices cached, no account needed): https://yapit.md/listen/3bde213b-3a5a-465f-9198-be65430b699e...

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.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…

Built a ~9M param LLM from scratch to understand how they actually work. Vanilla transformer, 60K synthetic conversations, ~130 lines of PyTorch. Trains in 5 min on a free Colab T4. The fish thinks the meaning of life is food. Fork it and swap the personality for your own character.

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
