Cortex — AI Review Assistant

About

Cortex adds an AI review copilot directly onto GitHub pull-request pages — no third-party SaaS, no data middleman. You bring your own Anthropic API key, and everything runs between your browser, Anthropic, and GitHub.

What you can do:
• Highlight code in a diff and ask about it — answers stream into a dock, grounded in the real diff and the PR's intent.
• Overview — a deterministic, no-AI change map: files changed, additions/deletions and net per file, with a churn bar and a by-module rollup so you see where the weight is.
• Summarize the PR — TL;DR, key changes, per-file gloss, and a 1–5 review-effort rating.
• Review the whole PR — a findings list with Blocker/Major/Minor/Nit/Praise severity chips, with optional Security / Performance / Error-handling / Readability lenses.
• Test gaps — a fast, no-AI heuristic flagging changed source files with no matching test change.
• Suggest a fix — a committable GitHub suggestion block for the selected lines.
• Turn any answer into a line-anchored review comment, with a confirm step and a 10-second undo.
• Build a batch review and submit it with a Comment / Approve / Request-changes verdict.
• Conventional Comments labels, canned snippets, and per-PR conversation memory.

Privacy by design:
• Your key/token are stored locally and never synced or sent to us.
• Code is sent only to Anthropic (your key) — only when you take an action.
• A secret-redaction pass masks likely secrets before anything is sent.
• No analytics, no tracking, no third-party servers.

Cortex is GitHub-only and human-in-the-loop: it never posts or reviews on its own.
