We build a PDF toolkit that runs entirely client side. There is no upload endpoint on the domain, so documents are never transmitted. That constraint is the whole product.
Two months ago we added on-device AI: summarize a PDF, ask it questions, translate it. The setup:
- A 1.5B parameter model running in the browser through WebGPU
- Executes on the user's own GPU, inside a sandboxed worker
Merge, split, compress, organize and protect PDFs entirely in your browser. Your files never leave your device — there is no upload endpoint at all. No servers, no sign-up, no watermarks. It even works offline after the first visit. Free.
