CodebaseToPrompt is a simple tool that transforms local directories into structured prompts for large language models (LLM). It assists users in selecting files to include or ignore, outputting content in a format that can be directly copied to LLM for code review, analysis, or documentation generation. The main advantages of this tool lie in its high interactivity, ease of use, and the ability to operate directly in the browser without uploading any files, thereby ensuring data security and privacy. Background information indicates that it was developed by the path-find-er team to enhance developers' efficiency in utilizing LLM for code-related tasks.
