# Automated AI code review on every pull request

Install a GitHub App. Bring your Anthropic key, your OpenAI key, or both. Get detailed, context-aware code reviews from Claude and/or GPT — automatically, in minutes.

14-day free trial. $10/mo. No credit card required.

## How it works

**Install the GitHub App** — Add CodeMouse to your GitHub organization or personal account. Choose which repos to connect.
**Add your AI key(s)** — Connect your Anthropic key, your OpenAI key, or both. Connect both and each PR gets reviewed by Claude and GPT in parallel. Keys are encrypted at rest (AES-256-GCM).
**Open a pull request** — CodeMouse reviews it automatically and posts detailed comments directly on GitHub.

## Built for developers

**Full repo context** — Reviews use the entire repository, not just the diff.
**Claude, GPT, or both** — Connect one or both. When both are connected we merge the findings and drop duplicates, so you get a single consolidated review.
**Bring your own key** — No AI cost markup. You pay Anthropic and/or OpenAI directly (~$0.05–0.15 per review per provider).
**Reads the room** — Reviews every existing PR comment (humans, other bots, earlier CodeMouse runs) and won't repeat what's already been said. Follows up on its own threads when fixes land.
**Approves clean PRs** — When the diff looks good, prior concerns are addressed, and CI is green, CodeMouse actually approves the PR.
**No throttling** — Every review starts instantly. No queues, no rate limits.
**Works with any language** — TypeScript, Python, Go, Rust, Java — if it's code, CodeMouse reviews it.
**Inline comments** — Review comments appear on specific lines in your PR.
**Zero config** — No CI pipelines, no YAML files, no build steps.

## Simple pricing

**$10/month** with a 14-day free trial. Unlimited repositories, pull requests, and team members. No throttling — reviews start instantly. Plus your own Anthropic and/or OpenAI API usage (~$0.05–0.15 per review per provider).

## Frequently asked questions

- What AI models does CodeMouse use?
- Your choice: Anthropic Claude, OpenAI GPT, or both — powered by your own API keys. Connect both and each PR gets reviewed by both models in parallel; we merge the findings and drop duplicates.
- What happens when both models flag the same thing?
- We de-duplicate overlapping comments by file, line, and semantic similarity. You get a single consolidated review — not two bots arguing on your PR.
- Is my code stored?
- No. Your repository is cloned temporarily to run the review and deleted immediately after.
- Does it work with private repositories?
- Yes. The GitHub App uses installation access tokens scoped to the repositories you grant access to.
- How much does the AI usage cost?
- Typically $0.05–0.15 per review per provider. You pay Anthropic/OpenAI directly — we don't add any markup.
- Can I cancel anytime?
- Yes. Cancel through the billing portal. No contracts, no questions asked.
- Does it replace human code reviews?
- No — it complements them. CodeMouse catches mechanical issues so your team can focus on architecture and design.
