Icarus

Ask your codebase why, and get the receipt.

What it does

Ask why your code is the way it is. Icarus answers from your repository's own pull requests and issues, with citations, and says "no one wrote this down" when nobody did.

Icarus answers from your repository's own pull requests and issues, shows the evidence, and says “no one wrote this down” when nobody did. Live, on simonw/llm · 526 pull requests · 964 issues · 1,091 commits · 470 code windows · no sign-in Behind you: the real evidence graph, 2,599 nodes and 934 edges. Green is cited, amber is searched. Other assistants guess, confidently, and never say it was a guess. Icarus refuses instead, and the refusal is enforced by code rather than by asking a model nicely. The answer arrives with the pull requests and issues it rests on. Every citation resolves to evidence that was really retrieved, with a valid line range. “No one wrote this down.” Icarus found…from try-icarus.vercel.app

  • 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…

  • I made OwnTime to balance between competing priorities in my life. The idea is based on two main influences: the concept of "roles" from "The 5 Choices" (2015), and my repeated failure to effectively implement time blocking due to the necessary flexibility in my role. The app allows you to define time budgets, which are not much more than a few mutually exclusive countdown timers. The UX is essentially that of a chess clock for an arbitrary number of players with configurable time. The whole point of the app is to kick you out of the running role/priority when its time is up. One…
