About INT21

We are building self-improving AI systems for the software beneath modern AI. Our first product generates and optimizes low-level GPU software, then proves its work with tests and benchmarks. Today, we are launching INT21: the first company to achieve self-improving AI agent swarms, applied to AI infrastructure. That software has an outsized effect on speed and cost. The first four implementations produced by PTX Kernel Factory are open source today. The product is also entering beta, with early access available at int21.ai.

About Trace

A macOS menu-bar app that turns any conversation into a clean markdown transcript, with an optional on-device summary. Runs a local speech model entirely on your Mac, in dozens of languages. The moment is pinned to your transcript at the exact timestamp. Trace provides you with clear markdown transcripts and summaries that you can use anywhere. Either copy the markdown from Trace directly or have it place the file anywhere in your filesystem. Trace can also send files directly to Obsidian, Bear, Drafts or Things with a button press.
