Why Bento

Built for people who care where their documents go

A native Flutter app with a native PDF engine. No browser tricks, no servers, no fine print.

Works in airplane mode

Every engine module, font and asset is bundled at install time. Nothing is downloaded on first use — turn off Wi-Fi and everything still works.

Your files stay yours

No accounts, no sign-in, no analytics, no ads. Your PDFs never touch a server, because there is no server to touch.

Native document scanner

Scan paper with automatic edge detection, crop and filters, review multi-page results, then save as PDF or send straight into another tool.

32 themes, light and dark

Material You dynamic colour, Catppuccin, Dracula, Nord, Gruvbox and more — with live previews and a system-following mode.

Fast native engine

PDF processing runs on a native Rust core over FFI, off the main thread — so the interface stays smooth even on big files.

Files where you expect them

Results go straight to Documents/Bento by default — or any folder you choose — with previews before you save or share.

The toolkit

Everything runs locally, from a single file to a hundred-page batch.

FAQ

Questions, answered

Do my documents get uploaded anywhere?

No. Every tool processes files locally on your device. Bento doesn’t upload, sync or transmit your documents — there is no backend at all.

Do I need an account or an internet connection?

Neither. Install it, open it, use it. The app works fully offline, including the scanner and every PDF tool.

Which platforms are supported?

Android 7.0 (API 24) and newer, and iOS 13 and newer.

Is Bento free?

Yes. Bento is free to use.

Which permissions does the app need?

Storage access to open and save your files, and camera access for the scanner — requested only when you tap Scan. No background access.

How do I report a bug or request a feature?

Email [email protected] with as much detail as you can — screenshots and the PDF that caused the issue help a lot.
