Why Omnitrix exists
When you upload a contract to a PDF tool, compress an image on a free site, or run a document through a grammar checker — that file lands on someone else's server. Processed by their infrastructure. Sitting in their logs. For most tasks that's an accepted trade-off. For professionals handling sensitive work, it shouldn't have to be.
The Omnitrix guarantee
Your files never leave
your device.
Not "we encrypt them in transit." Not "we delete them after 24 hours." Every tool runs as compiled WebAssembly inside your browser tab. Your file is loaded into memory, processed, and handed back as a download. It never touches a network interface — not even for a millisecond. There is no server to breach. There are no logs to subpoena.
HOW IT WORKS // TIER 01
Every core tool runs as compiled code inside your browser. Your file is processed entirely in memory on your own machine and handed back as a download. Split, merge, compress, background removal, OCR, format conversion — all of it. No network request is made at any point.
TIER 02
The same local engine in a native app. Drag entire folders. Batch hundreds of files. Fully offline. No browser required. Under 12MB.
TIER 03 — OPT IN ONLY
The summariser and writing assistant extract text on your device first. Only that text is sent — never the file itself. You press the button. You see what's sent. Every time.
