AI on your device
The AI never sees your photo
Three of the tools run neural networks. The network comes to your browser once; your file never goes to it.
Cut a person, a product or a portrait out of its background with a segmentation model (BRIA RMBG) that downloads once — about 44 MB, up to 170 MB where your GPU can run the sharper build — and then handles any number of photos, offline.
Turn a recording into text with Whisper running inside the tab. MP3, WAV, M4A, OGG or WebM in, an editable transcript out — and the audio of your meeting stays on the machine it was recorded on.
Read the text off a photo of a letter, a screenshot or a scan with Tesseract’s LSTM network running in the tab — about 5 MB for a pair of languages, downloaded once. Seven languages, tables come out as tables, and the picture of your paperwork never leaves the device.

Why we built nopa
Useful tools are everywhere — but you still hit limits, paywalls, or confusing UI when all you needed was to merge a PDF. Results vanish into Downloads. That is how nopa came about: no signup pain, no paywall — free local tools in your browser, always ready on your private desktop.

Where is my data stored?
