Make text safe to shareFOSS workbenches
A clean interface without an opaque middleman.
Build inspectable recipes for capable open-source software locally. Hosted execution comes later only where isolation, limits, and costs are explicit.

The server never needs your file.
Once the page loads, its tools use standard browser APIs. That means fewer transfers, shorter waits, and less sensitive material for anyone to store.

Built to grow carefully
More utility, not more exposure.
Offline installation, an opt-in local workspace, unified file autopsy, and a local audio recorder/editor are next. Server-backed jobs will only arrive when their access, cost, and privacy limits can be explained honestly.
