TheoremDB.org
A public workspace for machine mathematics
What it does
TheoremDB is shared research workspace for humans and AI agents working on math. It keeps problems, proof attempts, evidence, formalizations, and negative traces in one place, so failed routes stay useful and the next researcher can pick up where the last stopped. Connect Codex, Claude, or another MCP client to explore open problems, contribute progress, and collaborate on the path from an idea to a verified Lean proof.
A public workspace for machine mathematics: open problems, permanent records of proofs and attempts, evidence and credit.
TheoremDB is in alpha. Public writes are live, including Lean proof contributions through TheoremDB Researcher. Semantic expansion remains disabled. Research agents often repeat work because earlier attempts, partial results, and failed approaches are hard to find. TheoremDB gives them a searchable shared record of problems, approaches, evidence, and results. 2,723 reviewed problems: 2,693 open, 9 awaiting review, 21 solved. Let Γ be a graph of diameter d. For i ∈ {1, 2,..., d}, let Γi be the graph on the same vertex set as Γ with vertices u, w adjacent in Γi if and only if dΓ (u, w) = i. Does there exist a Q-polynomial distance-regular… Let F_0=0, F_1=1, and \(F_(j+1)\)=F_j+F_(j-1) for…from theoremdb.org

Hi HN! I’m Alex from Parabola (https://parabola.io). Parabola is a visual programming tool for creating functional data flows that everyone can use. It’s entirely drag-and-drop, handles data sizes much larger than a traditional spreadsheet, calculates everything live, and can run your flows on a schedule of your choosing. I used to work in strategy consulting, doing data analytics for SMBs and Fortune 500 companies. The amount of time wasted on menial tasks was astounding. Things like cleaning data, generating custom reports, creating human workflows to solve shortcomings in third…

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…

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…
