Why In-Browser Sandbox Processing Beats Cloud Uploads

Most online document utilities upload your private records to remote servers, exposing you to severe privacy leaks and compliance breaches. Our platform operates on a local-first architecture. Your document buffer is loaded directly into your browser tab's sandbox memory.

By executing processing algorithms locally via WebAssembly, we eliminate intermediate storage risks and third-party trackers. Your legal papers, financial records, and credentials remain strictly confidential on your own machine.
