promptext extracts code context for AI assistants to use when responding to development questions.

About promptext
promptext is an open-source command-line tool, written in Go, that turns a codebase into context suitable for AI assistants such as Claude, ChatGPT and other LLMs. It scans a project, filters out unnecessary files, ranks the remaining files by relevance, and packages them into a token-efficient prompt that is copied to the clipboard by default.
It enforces token budgets so output stays within a chosen limit, and offers preview and dry-run options before generating anything. Output formats include PTX (the default), TOON-strict, Markdown and XML, with the format auto-detected from the output file extension. Token counting uses the cl100k_base tokenizer, described as compatible with GPT-4, GPT-3.5 and Claude. Configuration is available through a project-level .promptext.yml file and global settings, and a Go API allows the extraction capabilities to be embedded in other applications. No pricing information is given.
