About Belay
Belay is an AI pair engineer for code that already exists. It is in development, and it is built on one rule: the developer makes every decision.
Why the name
In climbing, the belayer holds the rope. They feed slack when you move, lock off when you slip and call out the hold you cannot see. The climb, and every choice on the wall, stays yours. That is the job we want AI to do for developers.
Why we are building it
Developers spend a large share of their time understanding and debugging existing code, rather than writing new code.
Many AI coding tools focus on writing new code. Belay is built to help you understand the code you have: to trace a fault, to map a system you have not seen before, and to test a design before it is built.
Principles
- Developer leadsBelay proposes, you decide. Nothing ships without a human say-so.
- Show the traceEvery answer cites the files, tests and assumptions behind it, so you can check the reasoning.
- Catch the fallBlast-radius checks, tests and rollbacks come before risky changes. The safe-change workflow that carries this principle is planned.
- Leave them strongerBelay explains the system as well as the fix, so the team keeps growing.
