Pros and cons

Greptile

Pros

  • 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.
  • Free tier for one developer, free use for qualified open source, and 50% off for early startups.

Cons

  • 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

Pros

  • Answers cite the uploaded sources, so claims can be checked against the original text
  • Free Standard tier with 100 notebooks and 50 sources per notebook
  • Wide range of outputs, including Audio Overviews, Video Overviews, mind maps, flashcards, quizzes and slide decks
  • Accepts PDFs, websites, YouTube videos, audio files, Google Docs and Google Slides
  • Available on web, iOS and Android, and synced with the Gemini app

Cons

  • 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
