Kai Context
Kai provides an agentic AI code review and development platform that works in isolated workspaces, separate from a developer's checkout. The system indexes codebases into a semantic graph, independently verifies review claims before publishing, and can apply and recheck fixes with required tests passing. It scores an F1 of 46.5 on Martian's open code review benchmark, beating CodeRabbit and Greptile v5.

Problem
AI code reviewers often produce noisy, unchecked findings, lack context about the broader codebase, and cannot fix the issues they flag. Other tools throttle usage, impose metered overage charges, and require giving write access to repositories, creating security and trust concerns for engineering teams.
Solution
Kai provides an agentic AI code review and development platform that works in isolated workspaces, separate from a developer's checkout. The system indexes a codebase into a semantic graph of functions, symbols, call relationships, and dependencies, allowing the reviewer to trace a change's impact across callers, dependent code, and covering tests. A separate model independently verifies claims before they are published to a pull request, reducing false positives. Flagged issues are routed back to a coder agent that applies a fix, and the reviewer rechecks the change while required tests must run and pass before the task is marked complete. Users can also request fixes and have Kai push changes only when explicitly asked, with every permission held by the tool listed on a Security page.
Target Audience
Primary users are software development teams and engineering organizations that want trustworthy, context-aware AI code review without giving write access to their repositories, and that need fixes applied and verified within the review workflow.
Features
- Semantic graph indexes functions, symbols, call relationships, and dependencies across the codebase, with a semantic diff showing which functions and behaviors changed
- Independent review model checks the diff against the codebase and verifies each claim before it is published
- Coder agent fixes flagged issues and the reviewer rechecks the change with build and test feedback required to pass
- Isolated workspaces use Kai snapshots rather than git branches, allowing parallel agents and safe experimentation with push/fetch, shelve/unshelve, and fork point control
- Kai Review on GitHub provides automated PR review with inline comments and conversational follow-up via @mentions
- Kai VCS includes snapshots, a git bridge, changesets, signed stages, and two-way sync
- MCP server gives Claude Code, Codex, and Cursor access to the same graph tools: symbols, callers, callees, dependencies, impact, tests, and context
- Verified completion with a challenge step and findings ledger ensures claims are checked independently and issues are tracked until resolved
- Benchmarked on Martian's open code review benchmark: F1 of 46.5 vs CodeRabbit 43.5 and Greptile v5 38.8 (judged by Claude Sonnet 4.5)
- Published pricing with no "unlimited" claims: each seat's monthly usage and daily limit are shown, with Plus at $15 per seat per month and usage pooled across the organization
