What is Plandex?
Plandex is a terminal-based AI development tool designed to plan and execute large coding tasks that span many steps and touch dozens of files. It handles up to 2M tokens of context directly (~100k per file) and can index directories with 20M+ tokens using tree-sitter project maps. Plandex combines the best models from Anthropic, OpenAI, Google, and open-source providers to build entire features and apps with a robust terminal-based workflow. It's ideal for developers who need to make large-scale changes across complex codebases.
