Proof, by Torem Labs

AI agents write more of your code every day. The speed is real, but the responsibility never moved: it is still your name on what ships. Proof is where a person owns that. Before the run, work the problem on a visual canvas: frame it, split it into concepts, explore variations, ground them against your real repo, and hand the chosen idea to your agent. After the run, review the change as a concept map instead of a wall of diffs. See what the change actually touches, get plain-language explanations, clear the safe parts, approve or flag the rest, and sign off. Every decision lands in a signed, exportable verification record, and Proof keeps its analysis memory in a .proof folder inside your repo. Works with any agent that opens pull requests (Claude Code, Codex, Cursor, and others), and ships an MCP server so agents can work inside the same workspace. Bring your own API key, free, or use managed credits. For teams: shared workspaces, sign-off policies, auto-merge on a clean sign-off, and a reports view of every signed review.
