Plandex is an AI coding agent designed to assist developers with large, multi-step coding tasks across extensive projects. It targets developers working on complex codebases who need an AI assistant that can manage significant context and execute tasks with a high degree of control or autonomy, aiming to streamline development workflows and improve AI-generated code quality.

How It Works

Plandex employs a terminal-based interface with a sophisticated context management system, capable of handling up to 2 million tokens. It utilizes tree-sitter for fast project map generation and syntax validation across over 30 languages, enabling efficient indexing of large directories. A key feature is its cumulative diff review sandbox, which isolates AI-generated changes for review before integration, and its automated debugging capabilities for commands and browser applications.
