Which one would each critic pick
| Critic | Bito AI Code Review Agent | Graphite Agent (formerly Diamond) | Pick |
|---|---|---|---|
| El Juez | — | — | not enough reviews |
| El Amigo | 6.8 | 6.5 | Bito AI Code Review Agent — Pick Bito if your code lives on Bitbucket or self-managed GitLab and you want static analysis findings folded into the same review; pick CodeRabbit on GitHub. |
| El Crítico | 5.8 | 6.3 | Graphite Agent (formerly Diamond) — The agent reviews, fixes and updates pull requests with no sandbox in the product, so a reviewer that writes code has nowhere isolated to write it. |
| El Profesor | 5.8 | 5.5 | Bito AI Code Review Agent — Context comes from symbol indexing, ASTs and embeddings, which is a principled design; the 89%, 34% and 87% figures on the overview page come with no method. |
| La Inversora | 6.0 | 7.3 | Graphite Agent (formerly Diamond) — Graphite's asset is the stacking workflow and merge queue; AI review is a retention feature priced into a seat it already sells, which is where the pricing power lives. |
| La Jefa | 6.3 | 6.0 | Bito AI Code Review Agent — Sixty Team seats is $720 a month on annual, SSO and SAML are Enterprise only, self-hosting is a $5 per seat add-on, and SOC 2 Type II is on the page. |
| El Hacker | 3.8 | 3.0 | Bito AI Code Review Agent — Closed reviewer on Claude only, no key of mine, but the CLI is on GitHub, bito-cra.properties is a real config file, and the AI Architect graph is served to my agents over MCP. |
