AI that runs on your device

Each model downloads to your browser once; after that the work happens on your device.

Background Remover

Cuts a person or a product out of a photo. The model downloads once (about 44 MB, up to 170 MB on a strong GPU) and then works offline.
Audio Transcriber

Turns MP3, WAV, M4A, OGG or WebM into editable text with Whisper in the tab. The audio of your meeting stays on your machine.
Image to Text

Reads the text off a photo or a scan in seven languages, tables included. Tesseract downloads once, about 5 MB a language pair; the picture stays on the device.
All AI tools

Play NES games in your browser

A desktop in your browser

Apps open in windows, favorites sit on the Dock, and every result you save lands in nopa Files, where you can find it next week.

Why we built nopa

Useful tools are everywhere, and you still hit limits, paywalls or confusing screens when all you needed was to merge a PDF. Then the result vanishes into Downloads. That is how nopa came about: no signup pain, no paywall, free tools that run in your browser and keep your work on your own desktop.

Questions

Is nopa free?

Yes. Every app is free: no paid plans, no daily caps, no task counters. The only limits are file size and page count, set by what your device can handle.

Do I need an account?

No. Open any app or the desktop without an email or a password.

Where is my data stored?

In your browser on your device. Files stay local unless a specific app explains otherwise.

Can I use an app without the desktop?

Yes. Each app has its own page with a working mini version. Copy or download the result, or open the desktop to keep working.

Can I install nopa as an app?

Yes. Add nopa to your home screen or desktop from your browser menu. You get quick links to apps, and many keep working offline after the first visit.
