- MCP integration for agent verification before commit
- GitHub App for automatic pull request reviews
- Grounded findings with file, line, and evidence for each issue
- Per-review model selection on paid plans
- No repository connection required; only files from the agent are read
- Code review artifact retention and export
| - User journey visualization for pull requests showing blast radius and impact
- AI-generated flow diagrams from code using Claude
- Drill-down to actual code and methods behind each step
- Call graph visualization showing method relationships

| What makes it different | - Checks code context outside the diff, not just the change itself
- Dual independent reviewer reconciliation catches contradictions humans need to judge
- Only grounded findings block; AI certainty is not enough
- Does not train on customer code and never will
- Integrates with coding agents before commit to catch issues early
| - Visualizes code as interactive maps with user journeys showing the full blast radius of changes
- Runs locally on your Mac with only Claude API calls going over the network
- AI-generated flow diagrams connect pull requests to actual business logic via real code methods
- Uses language-specific parsers for accurate code analysis instead of heuristics
- One subscription covers all your Macs with no signup or card required for first month
