Trace — Demo video

Trace solves the problem of devs and vibe coders not understanding a codebase. Whether through too much AI code or lack of onboarding docs, Trace turns the repo into an interactive map so they can visualize whats actually going on. Every claim is checked against the source and links to the exact line that proves it.
