Archi is the Paperless-NGX client for iPhone, iPad and Mac that runs AI and OCR entirely on your device — no cloud subscription, no data sharing, zero privacy compromises.
Try it for free: the first 10 captures are included. After that, a one-time purchase unlocks the full version — no subscription, no cloud, no data collection.
Note: AI metadata extraction requires a one-time download of the Gemma 4 model (approx. 2.4 GB) after installation.
■ WHAT ARCHI DOES
Scan a document, recognise text, extract metadata — all in seconds, all locally. The document then lands neatly categorised in your self-hosted Paperless-NGX server.
■ ON YOUR DEVICE, NOT IN THE CLOUD
• OCR with Apple Vision — fast, offline, free
• AI metadata extraction with Google's Gemma 4 — runs directly on your iPhone, no server needed
• Automatic title, tag and correspondent suggestions based on content
• Import PDFs and images from other apps via the Share sheet
■ PAPERLESS-NGX INTEGRATION
• Browse and manage your entire document archive
• Full-text search across all documents
• Filter by tags, document type and correspondent
• Offline queue — scans saved locally until you're back online
■ REAL-WORLD USE CASES
Tax Returns: Scan every receipt, invoice and bill as it arrives. Archi automatically recognises the date, vendor and amount — and suggests the right tags. Come January, your self-assessment paperwork is already organised.
Home Office & Business: Incoming invoices, delivery notes, contracts — Archi reads the document and proposes correspondent, document type and filing date without you lifting a finger.
Medical & Insurance: Digitise NHS letters, insurance policies, prescription records and medical documents securely. Your health data never leaves your device.
No Wi-Fi? No Problem: Scan documents underground, in thick-walled archives or abroad without mobile data. Archi queues everything locally and syncs automatically when connectivity returns — unlike server-dependent alternatives.
Homelab & Self-Hosting: Running Paperless-NGX on a Synology NAS, Proxmox, Docker or a Raspberry Pi? Archi was built for exactly your setup. No third-party SaaS, no monthly fees, no vendor lock-in.
■ PRIVACY FIRST
No account. No subscription. No cloud.
Your documents stay on your device and your server — and nowhere else.
All AI processing, all OCR, all metadata extraction runs exclusively on your iPhone. Archi never transmits document content to any external server — not Apple's, not Google's, not ours.
