Hi Product Hunt! π
I'm excited to share Nada Sai ("Nothing Leaves" in Portuguese) with you today!
Like many of you, I frequently need to convert a PDF, strip background from an image, cut an audio clip, or obscure sensitive information on a document. But almost every popular online tool forces you to upload your personal files to unknown cloud servers.
For contracts, ID cards, financial reports, or private photos β thatβs a huge privacy risk.
That's why I built Nada Sai: a privacy-first web app with 33 tools running 100% client-side inside your browser.
π How it works:
- Zero backend servers. Every conversion, edit, compression, and AI operation runs locally using WebAssembly (WASM), Web Workers, and Canvas APIs.
- Background removal uses an in-browser AI model (IS-Net).
- OCR (text recognition) uses local Tesseract WASM.
- PDF to Word (.docx) parses pages in-browser without sending a single byte anywhere.
- AES-256 encryption encrypts files directly in your browser tab.
- PWA ready: Once loaded, it works entirely offline.
Iβd love to hear your feedback, tool requests, and thoughts!
