Use of AI-Generated Content at users' own risk: Users assume full responsibility for any damages suffered by users or third parties arising from the use or inability to use AI-Generated Content (including minutes, summaries, transcriptions, formatted documents, etc.), and we shall not be liable except in cases of our own willful misconduct or gross negligence.

Users shall determine the legality of commercial use of AI-Generated Content at their own responsibility.
