Introducing PlumbThe proof engine

Architecture Findings With Receipts.

ArchAI checks a codebase against your team's engineering rules and proves every finding with a file-and-line receipt. If something can't be proven from the code, it says so instead of guessing.

Receipts, Or Silence.

Proven, not guessed

A verified violation needs evidence: the rule, the file and the line. Every finding carries its receipt, and the same input gives the same result.

Explore fast, verify after

AI-assisted agents help you explore and explain. They are labelled as such, and anything they suggest can be turned into a rule and proven.

Portable knowledge

Findings, rules and the dependency map export as an Open Knowledge Format bundle, readable without the source code.

One Firm. A Family Of Agents.

Each agent is a real command. Proof agents never use AI. Insight agents do, and say so.
