Independent Apple-native software

Apps with honest boundaries.

Published by Gunnar Hostetler

Five products with clearly documented data paths. Explore private document intelligence, device-document finding, direct API clients, and hybrid retrieval tools, then see exactly what stays local and what does not.

Featured · Version 5.1

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.

Products

Each page is written as a publisher surface for App Store review, user support, and technical evaluation: what the app does, which APIs it depends on, what stays local, and where the support and privacy routes live.
