The invention of our platform required moving away from the "Request-Response" model that has dominated the web for decades. Traditionally, web apps act as thin clients that send all data to a powerful central server. We inverted this by treating the user's browser as the powerful server itself.
By leveraging WebAssembly, we successfully ported complex C++ and Rust PDF libraries directly into the browser. This allows One Doc to perform high-level manipulation like redaction and merging without a single packet of your document data ever leaving your local machine. This was not just a coding task; it was an invention of a new workflow for the privacy conscious era.
