An AI tool that coordinates complex changes across multiple files directly from the terminal. It uses LLMs to understand the codebase and apply edits, focusing on developer productivity and precise control.

What problem it solves¶

Enables developers to make coordinated, multi-file changes from the terminal with AI assistance, reducing the manual effort of large refactors and cross-cutting edits.

Where it fits in the stack¶

Development & Ops. Functions as a terminal-based AI coding assistant for multi-file editing.

Typical use cases¶

Coordinating complex changes across multiple files
Codebase-wide refactoring from the terminal
Applying precise, controlled edits with AI assistance

Strengths¶

Terminal-native workflow
Focuses on precise control over edits
Good for multi-file coordination

Limitations¶

Depends on external LLM providers
Smaller community compared to alternatives like Aider

When to use it¶

When you need precise, multi-file edits from the terminal
When codebase standardization tasks require coordinated changes

When not to use it¶

When a graphical editor experience is preferred
When single-file completions are the primary need
