Featured · Version 4.6

OpenIntelligence turns PDFs, Office documents, code, images, audio, and video into private, searchable libraries. Retrieval and verification stay local; supported devices can use Apple Private Cloud Compute for final synthesis only after the evidence payload is shown and approved.
