Answers,
before you ask.

iPhone 15 Pro or later, on iOS 26 or later. Apple Foundation Models requires the A17 Pro Neural Engine. Papera will install on older devices but the on-device AI features are gated. iPad runs the same app with an adaptive sidebar today.

iPad runs the same app with an adaptive sidebar today. A native Mac version is on the roadmap once Apple Foundation Models reaches feature parity on macOS — likely 2027.

Yes. App Intents power Siri (“Scan a receipt”, “Find last month’s invoices”), and a Quick Scan widget plus a Recent Documents glanceable widget ship with the app. Custom prompts you save are exposed as Shortcut actions automatically.

No — not by default. All scanning, OCR, and AI processing run on your iPhone. The only outbound traffic is iCloud sync (your private CloudKit container) and, if you opt in, the cloud AI provider you chose using your own API key. The full data-flow diagram is on the Privacy page.

If you’ve enabled iCloud sync, your library reappears on your next iPhone the moment you sign in. If you haven’t, the documents stayed local — which means they were never at risk of leaking, but they’re also gone with the device. There is no Papera-side recovery path because there is no Papera server.

Yes. Settings → Providers. Drop in a key, validate, switch model per task. Keys are stored in iOS Keychain. You can fall back to Apple Foundation Models any time by toggling the provider off. Supported today: OpenAI, Anthropic, Google Gemini, custom OpenAI-compatible endpoints (e.g. local Ollama).

Apple’s Vision framework recognises Vietnamese print at >95% accuracy on well-lit captures. Handwritten Vietnamese is harder — Papera flags it during processing so you know to verify. Diacritics on faded receipts are the most common failure case.

Yes. Save a prompt as a “recipe” — e.g. “List every action item, include the page number” — then apply it to any folder. The recipe runs sequentially on-device, or in parallel on the cloud provider you chose. Output streams into a single combined report you can copy or send to Shortcuts.

Free. There is no subscription, no tier, no paywall on AI. A Tip Jar lets you support development if you want to — three premium themes (Dark Ocean, Forest Green, Warm Sunset) ship as a thank-you for tipping. Every other feature ships free for everyone.
