What it does
Repowise builds a map of a software project, including which parts call which, its change history, tests, documentation and past design decisions. It does this once on your own machine, then updates it as code changes.
You or your AI coding agent can then ask questions such as 'what breaks if I change this?', 'what code is unused?' or 'why was this built this way?'. It connects to agents like Claude Code, Codex and Cursor through MCP, a standard way to give AI tools extra abilities.
Its makers say this lets agents stop re-reading files, which saves tokens (the units AI services charge for). The core features need no AI key. A hosted service and enterprise features are offered for a fee.
Who it's for
Developers and engineering teams who use AI coding agents on large or unfamiliar codebases.
Can I use it without coding?
Developers only. It is installed as a Python tool and used alongside coding agents, so it suits programmers. New to this? Start here.

- Or install Repowise yourself with a Python tool installer and run its setup in your project folder.
- Ask your agent questions, such as what would break if you changed a certain file.
