# What is Plandex?

Plandex is an open-source CLI AI coding engine designed for complex, multi-step tasks that span many files. It maintains a protected draft state and accumulates changes in a sandbox before applying them, reducing the risk of breaking things mid-task.

Who is it for? Developers and teams who want to delegate multi-step coding tasks to an autonomous agent.
