Learn from the work you're already doing.
Hephaestus is an open-source AI mentor for software teams. It reads the work developers already do in GitHub, GitLab, Slack and Outline against the engineering practices their project cares about — a curated set of practices ships with it — and delivers feedback on the work itself, on the developer's own practice pages, or in conversation. Every piece of feedback names the practice it came from and points back to the work it saw, and developers can ask why, push back, or talk through the next step.
Feedback on how you work is a mentor's job, and there is never enough of that attention to go round. Hephaestus carries the routine part so that everyone gets some — the harder judgement and the relationships stay with people.
Hephaestus is developed by the Research Group Applied Education Technologies (AET) at the Technical University of Munich (TUM), where it mentors students in project-based software engineering courses. It is built to run anywhere a team works.
