What happened

A class-action lawsuit filed in northern California accuses Otter.ai of failing to ask attendees for permission to record their meetings and fails to alert participants that recordings are shared with Otter to improve its AI systems. 

The lead plaintiff, Justin Brewer of San Jacinto, California, alleges his privacy was "severely invaded" upon realising Otter was secretly recording a confidential conversation. Notably, the plaintiff wasn't even an Otter user; his conversation was captured simply because another participant had the tool running. Several other plaintiffs later joined a consolidated case. 

The system impacted both registered users and non-subscriber third parties who never agreed to Otter's terms of service by intercepting and exploiting sensitive medical, financial, and professional discussions.

Why it happened

The issue stems from Otter’s architectural design, which relies on automated bots joining scheduled calendar events as "silent participants," alongside data retention practices that store audio and transcripts for model training.

Transparency and accountability limitations compounded the issue: Otter’s business model attempted to shift legal compliance obligations onto meeting hosts (requiring them to ensure permissions) while omitting clear real-time consent pop-ups or mandatory opt-ins for non-subscriber attendees on the call.
