Privacy-First Document AI Using On-Device Models

C6/10April 3, 2026
WhatA desktop app for lawyers, doctors, and accountants that uses Apple's on-device vision and language models to OCR, classify, extract, and summarize sensitive documents without any cloud dependency.
SignalMultiple commenters emphasize that business risk from sending sensitive data to cloud AI is becoming untenable, and that Apple's on-device vision and OCR models are surprisingly strong — the privacy angle for local models will only get more compelling as data breach stories accumulate.
Why NowApple's on-device vision and OCR models have reached production quality in Tahoe, while high-profile incidents of confidential data leaking through cloud AI services are making regulated professionals desperate for air-gapped alternatives.
MarketSolo practitioners and small firms in legal, medical, and accounting (~2M in US alone); willingness to pay $50-200/mo for compliant document processing; competes with cloud-based tools like Clio AI or Robin AI but with a hard privacy guarantee.
MoatVertical-specific document templates and extraction pipelines trained on domain data create compounding accuracy advantages that horizontal tools can't match.
