How it works
Create a vault
Create dedicated spaces for your documents — for work, home, or anything else. One local vault is free. Multiple vaults and iCloud sync across your devices are Pro.
Import & scan
Bring in any document or image — from Files, Camera, or anywhere else. DocDuck converts everything to PDF, ready to organize and protect.
Tag, summarize & search
Add tags and write a summary for each document. Find anything instantly with fuzzy search across names, tags, and content.
Mask & send
Redact names, addresses, IBANs, tax IDs before sharing with anyone, including AI. Runs entirely on-device. Nothing leaves your phone.
Auto-summarize & auto-mask
Let DocDuck analyze your documents and suggest summaries and masks automatically. On-device — no cloud, no third parties.
