According to the vendor's site, Jank is an AI quality agent distributed as plugins for coding agents including Claude Code, Codex, Cursor, Antigravity and Claude Desktop, plus an MCP server. The site describes it inspecting recent code changes, running focused code, browser, API and user-style checks, and revalidating fixes inside the local project. It is invoked through /jank slash commands in the coding agent. The site lists a free local plan, a usage-based public cloud plan and a custom private cloud plan. The product is in early access. The cotestpilot.ai domain redirects to jank.ai.
