A few details

Will Gravity be free?

Yes. Gravity is planned as a free download.

Does it need the internet?

Internet is required for initial model installation. After that, document recognition runs offline.

Which files can I open?

Gravity supports PDF, PNG, JPEG, and HEIC files.

Which model does it use?

GravityOCR-KO, a version of GravityOCR further trained on Korean documents, both released by Trillion Labs. The weights are on Hugging Face and the technical report is on arXiv.
