Poly-Glot AI

About

Poly-Glot is an AI-assisted code comment generator and documentation standardizer for software projects. It takes existing code that is undocumented or has inconsistent, AI-generated comments and produces consistent documentation in common styles such as JSDoc, PyDoc, Javadoc, KDoc, Doxygen, and others across 12 programming languages. In addition to traditional doc-comments that describe parameters, returns, and exceptions, it can generate “why” comments that capture intent, trade-offs, and reasoning to make code easier to maintain and more useful for AI coding assistants and search/retrieval workflows. Poly-Glot runs in the browser with a privacy-first approach: code is processed locally and calls go directly from the user’s machine to OpenAI or Anthropic using the user’s own API key. It also provides an npm-based CLI for batch processing files and directories, diffs, dry runs, backups, and use in pre-commit hooks or CI/CD pipelines.

  I love it, especially the CLI version with the npm library. You set it up once in seconds. Then, you just run a one-line command to add comments to every file in a directory. poly-glot comment --dir src/ --yes
