We build tools that keep advanced capability close to real engineering work — private by default, practical in daily use.
We come from engineering research — computational mechanics and particle simulation. That research is the root of both things we do: our own simulation software, and the practical AI tools we built to run our daily engineering work and kept because they were useful.
Our main work runs in two threads. One is our own engineering software: Phynexis, a platform for particle and multiphase simulation grown out of our research. The other is the practical AI layer: Xiaohe, a self-hosted agent platform with skills for documents, presentations, PDFs, and video. Xiaohe runs on top of industry agent harnesses and language-model APIs — the base models and the coding-agent runtimes come from Anthropic, DeepSeek, Kimi, OpenAI and others, and we don’t develop those. Our work is the layer that makes agents useful for real engineering work.
Xiaohe is our self-hosted AI agent platform: CLI, Session API, Web, Desktop, and Skills Hub. Heyue is a free companion Markdown reader. More products appear under Products as they ship.
Phynexis — our particle and multiphase simulation platform — is a flagship line in progress. Follow Products for updates.
