What SignDo is not

SignDo is AI-powered translation in Early Access. Results may vary, and it is not a replacement for a qualified interpreter. Please don't rely on SignDo for emergency, legal, medical, financial, or other high-stakes communication, and it does not satisfy legal accommodation requirements.
