Otter.ai is an AI meeting-transcription and note-taking app (desktop, iOS/Android, Chrome extension) that joins calls on Zoom, Google Meet, and Microsoft Teams to record, transcribe, and summarize conversations; it is operated by Otter.ai, Inc., a privately held Delaware corporation headquartered in Mountain View, CA. Otter's own privacy policy states the service collects audio recordings, automatic OtterPilot screenshots, uploaded text/images/video, and speaker-identification data generated from recorded calls and meetings, and separately discloses using de-identified audio recordings and transcriptions (which may still contain personal information) to train its proprietary AI models. The policy also discloses routine third-party ad-tech and analytics sharing (Google Analytics, Amplitude, Facebook advertising, and disclosure categories including "Mobile advertising tracking providers" and "Advertising Partners") with a CCPA-style "Do Not Sell or Share My Personal Information" opt-out, and Otter's own App Store privacy label self-declares that Identifiers data may be used to track users across apps and websites owned by other companies. In August 2025 a federal class action (Brewer v. Otter.ai, later consolidated in the Northern District of California) alleged Otter's Notetaker/OtterPilot recorded, accessed, and used the contents of private meetings without obtaining consent from all participants, and used those recordings to train AI models; the case was unresolved as of this research, and no live court-docket or administrator page could be fetched directly, so it is referenced here via contemporaneous legal-industry reporting on the filed complaint rather than the docket itself. No independent security audit, SOC 2 report, or regulator action was found in this research; Otter's /security URL currently resolves to a generic marketing page with no audit disclosures.
