Otter AI Review (2025): Smart Meeting Assistant Worth Your Time?

Otter AI achieves approximately 85-95% accuracy in most scenarios with clear audio and standard accents. Factors affecting accuracy include audio quality, background noise, speaker clarity, specialized terminology, and overlapping conversations. The Business plan offers the highest accuracy with custom vocabulary features that can be trained for industry-specific terminology.

In our testing across 30+ meetings of varying types, Otter AI performed impressively even with multiple speakers and moderate accents, though it occasionally struggled with highly technical terminology and very rapid speech. For critical transcriptions requiring perfect accuracy, human review is still recommended.

Yes, Otter AI supports importing and transcribing pre-recorded audio and video files. The free plan allows up to 3 imports per month, while paid plans offer unlimited imports. Supported file formats include MP3, MP4, M4A, WAV, and most common audio/video formats.

The import process is straightforward: simply upload your file through the web interface or mobile app, and Otter AI will process it, typically completing transcription in significantly less time than the actual recording length. Once transcribed, imported recordings have all the same features as live recordings, including speaker identification, search functionality, and automated summaries (on paid plans).

Currently, Otter AI primarily supports English with the highest accuracy, including various accents and dialects. As of May 2025, beta support exists for Spanish, French, German, Japanese, and Portuguese, though with somewhat lower accuracy compared to English.

Multilingual meetings present a challenge, as Otter AI does not currently support automatic language switching within a single conversation. For meetings conducted in multiple languages, the best practice is to create separate Otter sessions for each language segment. The company has announced that expanded language support with improved accuracy is on their development roadmap for late 2025.

Otter AI implements several security measures to protect conversation data, including TLS/SSL encryption for all data in transit, AES-256 encryption for stored data, and compliance with SOC2 Type II standards. The Business plan offers enhanced security features, including single sign-on (SSO), advanced account management, and custom data retention policies.

While these security measures are robust for most business needs, organizations in highly regulated industries (healthcare, finance, legal) should review Otter AI's security documentation thoroughly and may need to implement additional safeguards. For extremely sensitive conversations containing trade secrets or confidential intellectual property, companies typically establish internal policies about whether such content should be transcribed by third-party services.

Yes, you can cancel your Otter AI subscription at any time with no cancellation fees. For monthly subscriptions, you'll retain access to premium features until the end of your current billing cycle. For annual subscriptions, Otter AI does not offer prorated refunds for partial months – your subscription will remain active until the end of your paid term.

When you downgrade to the free plan, you maintain access to all previously created transcriptions, but will be subject to the free plan limits for new recordings. Otter AI also offers a 7-day free trial for all paid plans, allowing you to test premium features without commitment.
