Built at JEVATHON (w/ The AI Collective)

Blamejev

# Blamejev Ask any git repo's history a question in plain English and find the commit responsible, without paying an LLM to read every diff. **Problem** - Vibecoded apps pile up hundreds of "Fix error" bot commits - Owners don't know the code's words, so `git log -S`, `blame`, and `bisect` don't help - Coding agents pay to read diff after diff, mostly irrelevant **How it works** - Plain code turns each commit into a ~60-token fingerprint - TypeSafe **Jev** makes cheap, calibrated yes/no calls: which folders, which fix loops, which commits - A keyword safety lane and minimum budgets keep the right commit from being pruned - A Fireworks LLM verifies only the 5–15 shortlisted diffs - "When did it start" mode jumps through history in parallel
