Otter.ai is fighting to dismiss a consolidated federal class action that accuses its OtterPilot bot of quietly recording and transcribing millions of Zoom, Microsoft Teams and Google Meet conversations without participants’ consent. Privacy lawyers say the Otter.ai lawsuit could redraw the compliance map for every AI meeting assistant sold into the enterprise.
Four Lawsuits Consolidated in the Northern District
The action, In re Otter.AI Privacy Litigation (5:25-cv-06911-EKL, N.D. Cal.), bundles four putative class suits filed between August and September 2025. Brewer v. Otter.ai, filed on 15 August by San Jacinto resident Justin Brewer, led the way. Walker, Theus and Winston followed within a month.
Judge Eumi K. Lee consolidated the cases on 22 October 2025 and appointed interim co-lead counsel from Levin Law, Clarkson Law Firm and Werman Salas. A consolidated complaint was filed on 5 December.
What the Plaintiffs Allege Against Otter.ai
The core Otter.ai lawsuit allegation is simple. OtterPilot, now branded as Otter Meeting Agent, integrates with a user’s calendar and auto-joins any scheduled call as a visible participant. It captures audio, transcripts, screenshots and speaker voiceprints. Plaintiffs say Otter never obtains consent from other meeting attendees, and that the company has used captured data to train its speech recognition models.
The complaint asserts claims under the federal Electronic Communications Privacy Act, California’s Invasion of Privacy Act, Illinois’s Biometric Information Privacy Act, the Computer Fraud and Abuse Act and several state common-law theories.
Damages Exposure Runs Into Statutory Millions
The damages framework is unusually generous to plaintiffs. ECPA provides for the greater of $10,000 per violation or $100 per day. CIPA allows $5,000 per violation. BIPA runs $1,000 for negligent and $5,000 for intentional violations. Otter’s own 22 December 2025 press release put the service at more than 35 million users and over a billion meetings processed.
Otter’s Defence: Consent Belongs to the Account-holder
Otter has not issued a public statement directly about the litigation. Chief executive Sam Liang came closest in a TechCrunch interview published on 7 October 2025.
“If they accuse us, then they could accuse everyone else, all the tools you heard about doing meeting notes. My view is that we are on the right side of history. We’re building this new AI revolution. If you want AI to help, you need to put AI in the meetings.”
– Sam Liang, chief executive, Otter.ai, speaking to TechCrunch
The company’s legal position, set out in its motion to dismiss and a reply brief reported by MLex in April, denies any interception took place.
“Across all claims, plaintiffs do not plausibly allege that they disclosed private or sensitive information (or any information whatsoever), that Otter intercepted communications in transit, or that Otter accessed their computers or data without authorization.”

Otter’s terms of service already tell account-holders to “make sure you have the necessary permissions” before using the bot, a defence the plaintiffs argue fails in the all-party consent states of California and Illinois.
Writing in the firm’s Workplace Privacy Report, Jackson Lewis attorney Joseph Lazzarotti said the plaintiffs treat Otter as “an unauthorized third-party eavesdropper, intercepting communications and repurposing them for product training without consent.” He called the single-consent model “risky in states like California that require all-party consent.”
A Template for AI Notetaker Litigation
The case is already being read as the template for a broader litigation wave. Fireflies.ai was hit with its own BIPA class action in Illinois in December 2025 (Cruz v. Fireflies.AI Corp., 3:25-cv-03399), followed by a second case in the Northern District of Illinois. Both allege similar voiceprint-capture mechanics.
Read AI has avoided litigation so far but has been banned from Zoom and Teams integration at the University of Washington, Chapman University and the University of California, Riverside.
The Road to 20 May 2026
Otter’s motion-to-dismiss hearing is scheduled for 20 May 2026 at 10am in Courtroom 7 of the San Jose federal courthouse. Judge Lee’s ruling will be the first federal test of whether decades-old wiretap statutes reach an AI bot sitting quietly in the corner of a video call.
For now, the product remains in market while the legal questions continue to build around it. The bot is still taking notes!
We reached out to Otter.ai for comment, but it did not respond by the time of publication.
