?Frequently asked
6 questions
  • How accurate is Mesrai's AI review?+

    A well-tuned Mesrai review catches 70-90% of real issues with a false-positive rate under 10% on most codebases. Accuracy improves over time as Mesrai Rules tune themselves from your team's reactions to past findings — bot accuracy is a moving target, but the trend is consistently upward inside any given workspace.

  • What are Mesrai Rules?+

    Mesrai Rules are team-specific review rules written in plain English or YAML — things like "always use the structured logger, never console.log" or "tests must live next to their source file". Mesrai applies them on every PR alongside the built-in bug, security, and performance agents.

  • Can I use my own LLM key (BYOK)?+

    Yes — BYOK is supported on every paid plan. Connect OpenAI, Anthropic, Google Vertex, AWS Bedrock, Groq, Cerebras, or any OpenAI-compatible endpoint. Mesrai charges the platform fee; your LLM bill flows directly to your provider. Typical savings versus AI-Included at high volumes: 30-60%.

  • Does Mesrai work on monorepos?+

    Yes. The mesrai-graph AST engine builds a semantic index across the whole repository, so the review understands cross-package dependencies, type imports, and architectural boundaries — not just the diff in isolation. Tested on monorepos of 1M+ LOC.

  • How does Mesrai integrate with CI?+

    Three ways. (1) The cloud reviewer runs automatically on every PR via the git-provider webhook. (2) The Mesrai CLI (`npx mesrai review`) can run as a CI step inside GitHub Actions, GitLab CI, CircleCI, and similar. (3) The pre-push hook gives local-machine review before the PR even opens.

  • Is there a free trial?+

    Yes. 14 days, every Pro feature unlocked, 1,000 AI credits included. No credit card required, no auto-charge at the end. Sign up at app.mesrai.com.
