What it does

Description coming soon. We haven't written a summary yet. The line above is the developer's own description; the developer's README is linked above.

What you'll need

Detected automatically
  • An API key for some featuresWorks without one: figure, table and formula extraction runs locally with the bundled model. Needs a key (OpenAI-compatible provider and Anthropic): only the optional formula LaTeX recognition (OCR) needs your own provider API key.

Where your data goes

We found: its code only names services we could identify. 3 addresses in 1 group.
