pdfusion

A privacy-first PDF processing engine that runs entirely in your browser—deconstructing documents into text, images, and tables, then reconstructing them into pristine, structured Markdown. Static React SPA with client-side AI vision via Ollama, OpenRouter, or Gemini. Your files never leave your machine. Maintained by seehiong on GitHub, where it has earned 66 stars from the community.

It's actively developed around backend, document-processing, markdown, and is a solid reference for anyone building with these tools.
