Why Source Trace?

AI Git Blame

Track who wrote each line - AI or your teammate? Which version of each model was used, even months later.

ROI per model

Which subscriptions are worth renewing? Survival rate by model and language answers it on your codebase, not someone's benchmark.

Team Dashboard

Company-wide AI metrics in a shared dashboard. See how AI use is distributed across your team, languages, and repositories. Which models worth the budget.
