AI writes more of your code every quarter. Authors leave. Reviews get thinner. Grasp measures the number no dashboard tracks: how much of your codebase any currently-active human still genuinely understands — computed from git metadata alone, without reading a line of your source.
Sixty seconds from repo URL to a dark-code ranking. No signup, no code access.

Acquiring a codebase, auditing your own, or losing a key engineer? Fixed-fee diligence reports are available — deeper analysis, delivered in five business days.
Metadata only. Grasp reads commit history and PR events — never file contents. Hard evidence only. AI attribution counts co-author trailers and bot accounts; we report it as a floor, not a guess. Honest limits. The Grasp Score is a potential indicator — it tells you where to look, and we say so on every report.
