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, recognize text, extract metadata — all in seconds, all locally. The document then lands neatly categorized 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 Season: Scan every receipt, invoice and bill as it arrives. Archi automatically recognizes the date, vendor and amount — and suggests the right tags. Come April, your IRS paperwork is already done. 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: Digitize EOBs, lab results, insurance policies and medical records securely. Your health data never leaves your device. No Wi-Fi? No Problem: Scan documents in the subway, in a basement archive or while travelling. Archi queues everything locally and syncs automatically when you're back online — 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 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. ■ TECHNICAL DETAILS • AI model: Gemma 4 E2B INT4 (Google open weights) — runs fully on-device via LiteRT, Metal GPU accelerated • OCR: Apple Vision Framework — free, offline, privacy-preserving • Backend: Paperless-NGX (self-hosted, URL and token fully configurable) • Offline queue: SQLite-based, zero data loss when offline • On-device AI: iPhone 15 Pro or newer, or an iPad with 6 GB RAM (M-series). Scanning, uploading and your archive work on all supported devices — even without AI. • Runs on iPhone, iPad and Apple silicon Mac. Archi requires a self-hosted Paperless-NGX server. ## Key features - On-device OCR with Apple Vision - AI metadata extraction with Gemma 4 - Automatic title, tag, and correspondent suggestions - Import PDFs and images via Share sheet - Browse and search Paperless-NGX archive - Offline queue for scanning ## Recent user reviews (8 of 8) All indexed reviews: https://appshunter.io/ios/app/archi-paperless-scanner/id6762153317/reviews.md ### 5/5 — Genial *2026-07-22* Mehr geht nicht! Beste app ### 4/5 — Grundfunktionen Gut - KI Verwaltung ausbaufähig *2026-07-07* Die Grund Funktionen klappen alle gut. Scan ist schnell; Upload geht fix; Tags und Personen können live angelegt werden. Für die KI Erkennung hatte ich die Hoffnung das sie mein bisheriges System respektiert. Mein Namensschma ist immer yyyy-mm-dd_Title_mit_Wörtern. Dies wird nicht von der KI übernommen. Wenn ich bereits eine Person habe (DHL, Schufa,…) wird die nicht unbedingt wieder verwendet sondern neue mit zb. DHL Paket GmbH erstellt. Wenn dies irgendwann noch besser wird, ist es perfekt. **Developer response:** Danke fürs Feedback! Beide Wünsche sind bereits umgesetzt und kommen im nächsten Update: ein konfigurierbares Titel-Format (z. B. {date}_{correspondent}_{title} → 2026-07-07_DHL_Rechnung) und eine Option, mit der die KI bestehende Korrespondenten (DHL, Schufa …) wiederverwendet statt Duplikate anzulegen. Schon in einer Beta testbar. Freut mich, dass die Grundfunktionen gut laufen — danke! ### 5/5 — Nice App *2026-06-21* First impression of the app is very good. She does AI stuff very well for you. **Developer response:** Thank you very much ### 2/5 — Crash *2026-06-06* Before purchasing it’d be helpful to know that: a 2.4GB download is required; have to use SSL/TLS even on local network; ‘suchen’ & ‘scannen’ even if English is chosen language; dates are day-month-year not month-day-year so you’ll correct every scan (in US); auto scan crops aggressively, so have to use manual; crashes when processing more than one scan (iPhone 16 Pro, iOS 26.5); support is only if you have a GitHub account. Disappointed. **Developer response:** Thank you for the detailed feedback — these are fair points and several are already being worked on. HTTP/local network: a toggle for this exists in Settings → Security (and now also in the server setup screen as of v1.4.1 — sorry it wasn't visible during your setup). Date format: US date order (MM/DD) is on my list — I'll add it as a locale option. Model download size: I'll add this to the App Store description so it's clear upfront. Crashes with multiple scans: known issue, being fixed. Support without GitHub: noted — I'll add an alternative contact option. I'm sorry the experience fell short. ### 1/5 — Crashes *2026-06-03* Crashes on scan… **Developer response:** Hallo Schneppi, das tut mir wirklich leid — danke, dass du es meldest. Ich nehme Abstürze sehr ernst und will dir schnell helfen. Zwei Dinge, die meist sofort helfen: Falls du gerade von einer älteren Version aktualisiert hast: App einmal löschen und neu installieren — das behebt einen bekannten Update-Absturz. Deine Dokumente auf dem Server bleiben unberührt. Falls du das Beta-Feature „Fast AI" (Einstellungen → Erweitert) aktiviert hattest: bitte ausschalten. Hilft das nicht, würde ich dem Absturz gern direkt auf den Grund gehen — schreib mir bitte kurz über den „Feedback"-Button in der App (Einstellungen), idealerweise mit deinem iPhone-Modell. Ein Update mit weiteren Stabilitäts-Fixes ist außerdem schon unterwegs. Danke für deine Geduld — ich kümmere mich darum! ### 5/5 — Awesome *2026-05-07* This is an awesome app! I love it. Sadly, I can only use it on my iPad. Are there any plans to make the app available for Android? Would love to see it! **Developer response:** Thank you so much, really glad you're enjoying it! 🙏 Android is definitely on my radar — my current plan is to ship the feature-complete iOS version on June 1st, and then explore an Android port afterwards. I'll be honest though: I don't own an Android device myself, so that one will take some time to figure out properly. Stay tuned — I'll announce it here when there's news! ### 5/5 — Super Paperless Client *2026-05-07* Das ist wahrscheinlich die beste Paperless iPhone App, die ich genutzt habe. Der minimalistische Aufbau der App und die ganzen Feature die die App aktuell hat, sind einfach super. Auch war ich von der OCR Erkennung begeistert, wie gut die eigentlich läuft. Es ist auch toll, dass man für die App nur einmalig 0,99€ bezahlen muss und einem nicht irgendein monatliches Abo aufgezwungen wird. ### 5/5 — Super App *2026-05-03* Einmalzahlungen sind ein Segen und bei so einer tollen App unterstütze ich natürlich gerne! Die App ist aufgeräumt, minimalistisch und funktioniert hervorragen. Ich habe mich mit einem Feature-Wunsch an den Entwickler gewendet und der Wunsch wurde binnen zwei Tage umgesetzt. Näher am Verbraucher geht nicht! **Developer response:** Vielen Dank für die 5 Sterne! Deine Verbesserungsvorschläge sind klasse – ich werde sie direkt für das nächste Update einplanen. ## Frequently asked questions about Archi ### Does Archi have ads?

The AI model screen now clearly shows when the model is installed and ready. Creating an Archi link now keeps the document available offline. An Archi link now switches documents even when another one is already open. ### 2.2.1 — 2026-08-29 Fixes an issue where tapping a document in the list did not open it. ### 2.2 — 2026-08-29 You can now try Archi for free: the first 10 captures are included, after that a one-time purchase unlocks the full version. If you already bought Archi, everything stays unlocked and you won't pay again. Also new: • Learn from your archive — Archi looks through your existing documents and suggests a title scheme. You confirm each finding individually, and it only applies to future scans; existing documents are left untouched. • Templates — fill in title, tags, correspondent, document type and storage path in one step. For receipts you always file the same way. • Change owner — now shown by name and editable directly. • Share link — choose an Archi link that opens the document in the app, or a Paperless link with an expiry date for recipients without Archi. • On iPad and Mac the source document sits readable beside the fields during review, instead of a thumbnail. • Security: removing a client certificate now reliably revokes server access. • Fixed: on a warm device the scan aborted after the temperature warning without processing anything. ### 2.1.3 — 2026-08-08 New in 2.1.3 Fixes • The "automatic" metadata language now follows your device language instead of falling back to English. This affected Dutch, Polish, Ukrainian and Brazilian Portuguese — despite specially tuned prompts, those users ended up with English titles. If you set the language manually, nothing changes for you. Improvements • Tag suggestions now follow what you type: typing narrows the list, and the tags you use most appear first. ### 2.1.2 — 2026-08-04 New in 2.1.2 Fixes • Correspondents and document types you type into the edit sheet are now actually created — they used to be dropped silently. • The AI reuses an existing correspondent even when text recognition misreads the name — no more near-duplicates. • "Existing tags only" and matching to existing correspondents now apply to the suggestion itself, not just when you save. • Fixed a crash in the merge view. Improvements • Pick the correspondent manually in the merge view — even when neither the server nor the AI suggests one. • View the source document for a single suggestion too, not only when merging. • Optional scan recording for troubleshooting — only with your explicit consent, and everything stays on your device. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
