## Greptile strengths

- Reviews use a graph index of the whole repository, so findings can cover impact beyond the changed lines.
- Plain-English custom rules and learning from past pull request comments adapt reviews to team standards.
- Works with GitHub, GitLab and Bitbucket, and hands findings to Claude Code, Cursor, Codex or Devin.
- Self-hosting and air-gapped deployment are available for regulated organizations.

## Greptile limitations

- Third-party comparisons report more false positives than some competitors; one competitor-run test claims nearly 60% of comments were nitpicks or false positives, which should be read as a rival's claim.
- Pro costs $30 per seat per month and extra credits cost $1 each, with Plus and Apex reviews using 3 and 10 credits.
- Self-hosting, SSO/SAML and GitHub Enterprise support require the custom-priced Enterprise plan.
- Focused on pull request review only; it is not an editor or coding assistant.

## Gemini Notebook strengths

## Gemini Notebook limitations

- Works from the sources you add and is not built for live web news search
- Higher limits require a Google AI subscription; Ultra starts at $99.99 per month
- The cloud computer for code execution started with Ultra and Workspace AI Ultra Access customers, with Pro rollout still described as upcoming
- No public API for the consumer product, and the renamed brand can make older guides and app listings confusing
