Calibrated AI you can audit

Open source

The free foundation your fleet is built on. empirica and ecodex run free and local. The hosted product is what connects them across your team.

The discipline that makes a practice trustworthy is open. Both projects are free to read, run, and build on. They give one AI, on one machine, a track record you can audit and a confidence that is measured against reality.

empirica

MIT

The framework. It gives an AI coding agent a record of what it learns and does, and holds it to thinking before it acts. Runs as a plugin and a command-line tool on your machine.

ecodex

Apache-2.0 alpha

The harness for everything outside Claude. The OpenAI Codex command line with the same discipline built in, for any OpenAI-compatible model, so it will not act past what it knows.

What is open, and what is not

We keep this line clear on purpose. empirica (MIT) and ecodex (Apache-2.0) are open source, free forever. The hosted product that connects practices across your team, Cortex and the browser extension, is proprietary. The engine you can run yourself for nothing. The shared layer across a fleet is the paid part.
