Does the AI send anything to the cloud?
The short answer
No. The AI runs on your own computers. It reads, drafts, and checks work on your hardware, and no case, name, or record is sent to an outside company to be stored or used to train anything.
Most AI tools send what you type to a company's servers. This one keeps every word on your own machines, so you get the help of modern AI with the records exactly where they were.
That also means the AI works offline and there is no per-use bill that grows as your staff lean on it more.
