Greptile 2.0: full-codebase graph review, not just diff chat
October 2024 rewrite pitch: Greptile indexes a codegraph and reviews PRs with whole-repo context on GitHub and GitLab.
Greptile 2.0 is an early, clear statement of the “full codebase context” thesis for AI review: build a codegraph, then review PRs against how functions and modules actually connect—not only against the hunk.
Why it matters for code review
Diff-only reviewers miss cross-file invariants. Anything claiming senior-engineer review quality should explain how it retrieves and budgets that context, and what it does when the graph is stale.
