Greptile
AI code reviewer that understands your full codebase — automated PR reviews with deep context.
Overview
Greptile: AI Code Reviewer With Full Codebase Context
Greptile is an AI code reviewer that reads every PR with the context of your entire codebase — not just the diff. Most LLM-based code review tools see only the changed lines, which means they miss the kind of cross-file regressions and convention violations that human reviewers catch. Greptile indexes the whole repo and reviews each PR against that full context. The result: PR comments that read like a senior engineer who actually knows the code.
YC-backed and now used by hundreds of engineering organizations, Greptile has become the default AI reviewer for teams that want LLM-driven review without the false-positive noise.
Key Features
- Full-codebase context. Indexes the entire repo and reviews PRs against that context — catches cross-file regressions, convention violations, and architectural drift.
- GitHub & GitLab integrations. First-class PR comments, learning from the team's review history.
- Custom rules. Encode team-specific conventions ("never block the event loop", "use our internal logger") and Greptile enforces them.
- Severity-aware. Distinguishes blocking issues from nits, so reviewers don't drown in noise.
- Multi-language. Supports the major languages — TypeScript, Python, Go, Rust, Java, C++, etc.
- Codebase chat. Ask questions about the codebase directly; Greptile answers with citations to specific files.
- API. Embed Greptile reviews in your own dev tooling.
Ideal Use Case
Engineering teams of 5–500+ that ship multiple PRs per day, organizations with strict code conventions that need automated enforcement, fast-moving startups that want senior-engineer-level review without the senior-engineer headcount, and any team where PR review is becoming a bottleneck.
Why Use Greptile
Most AI code review tools (the GitHub-native ones included) review the diff in isolation and produce noisy, surface-level comments. Greptile is one of the few that does the harder thing — index the whole codebase and review with that context. The reduction in false positives compared to diff-only tools is the difference between "useful" and "muted."
FAQ
Is Greptile free? Free tier available for individual repos. Team and enterprise plans scale by repos and PRs.
Does it train on our code? No — Greptile uses your code to build a private index for review purposes. Code is not used to train models.
How does it compare to CodeRabbit? CodeRabbit also reviews PRs; Greptile's differentiator is the depth of cross-file codebase understanding. Both are credible; teams typically pick based on language support and integration depth.
tl;dr
AI code reviewer with full codebase context — catches cross-file issues other tools miss. The default LLM reviewer for teams that take review quality seriously.

Editorial Review
Our take on Greptile.
Greptile is an AI code reviewer that reads your full codebase for context-aware pull request feedback, cutting the manual review overhead.
What works
- Full-codebase indexing avoids shallow PR-diff reasoning
- Freemium barrier-free onboarding
- High community rating suggests practical accuracy
What doesn't
- Niche position; doesn't replace general coding assistants
- Requires adding yet another tool to CI/CD and review workflows
Greptile handles automated PR reviews by indexing your entire codebase, so it can flag issues against actual patterns and dependencies rather than guessing from isolated diffs. This is the core pitch: most AI code assistants see only what's in the current change; Greptile reasons about what you've built and how new code fits. In 2026, that context-awareness matters when reviewing larger refactors or cross-module changes where local reasoning fails.
The freemium model lets you try it without friction. Community rating of 4.82 suggests real users find it useful in practice, though 335 likes puts it in the solid-but-niche band—not yet a household name among developer tools. It competes against GitHub Copilot (which is everywhere but lighter on context) and Cursor (which is editor-first and broader). Greptile is narrower: specifically a PR reviewer, not an IDE or general coding copilot.
Where this works: teams with large codebases where PR reviewers spend real time context-switching. Where it struggles: small projects with simple diffs, or teams that prefer human eyes entirely. The bet is that full-codebase context justifies adding another tool to your workflow.
