Document capture • OCR • Apple Intelligence • GPT‑5 Nano

ChattyDOC

Accurate OCR for receipts, forms, and PDFs with privacy-first defaults. On-device Apple Intelligence comes first, with an opt-in GPT‑5 Nano fallback when layouts get tricky.

Built for App Store review readiness

On-device first

Apple Intelligence (iOS 18+) and Vision APIs run locally whenever available. Cloud is off by default.

GPT‑5 Nano fallback

If enabled, complex layouts route through our Vercel proxy to OpenAI GPT‑5 Nano Responses. No training, no retention.

Structured results

Headers, lists, and tables are preserved in Markdown output for easy export and sharing.

Compliance-ready

Privacy and Support URLs are live; required Reason APIs and Apple Intelligence usage are documented.

How we handle your data

Default path

Local processing

Images stay on device for first-pass OCR. Nothing is logged or used for model training.

Optional

Secure relay

If you enable cloud extraction, files travel via TLS to our proxy, then to GPT‑5 Nano. We request deletion after processing.

Control

Instant revoke

You can disable cloud processing anytime. Support channels are one tap away.
