Definition
Otter.ai is an AI-powered transcription and meeting-notes service that records audio, generates real-time speaker-labeled transcripts, and produces automated summaries and action items for meetings, interviews, and lectures.
Overview
Otter.ai emerged as one of the earliest consumer-friendly applications of automatic speech recognition (ASR) combined with natural language understanding to solve a mundane but universal problem: capturing what was said in a meeting without someone manually taking notes. It integrates directly with video-conferencing platforms like Zoom, Google Meet, and Microsoft Teams, joining calls as a bot to record audio and produce a live transcript that participants can follow along with, highlight, and comment on in real time. Beyond transcription, Otter's 'OtterPilot' feature uses generative AI to automatically produce meeting summaries, extract action items, and answer questions about past conversations through a chat interface. The product is aimed at knowledge workers, sales teams, journalists, students, and researchers who need searchable, shareable records of spoken conversations. Otter differentiates itself with strong speaker identification (it learns to recognize individual voices across meetings), a generous free tier, and deep calendar integration that automatically joins scheduled meetings. Enterprise tiers add admin controls, security certifications, and CRM integrations (e.g., Salesforce) so sales conversations can be logged automatically. As large language models improved, Otter layered summarization and Q&A on top of its transcription engine, shifting from a pure transcription tool to a broader 'AI meeting assistant.' Its main competitive tension is with newer AI-native note-takers like Fireflies.ai and Fathom, as well as built-in transcription features now shipping natively inside Zoom and Teams.

History
Otter.ai is an AI meeting assistant that records, transcribes, and summarizes spoken conversations in real time. It was founded in 2016 as AISense by Sam Liang and Yun Fu; Liang had earned a Stanford doctorate and previously led the location platform behind the "blue dot" in Google Maps. The first Otter app appeared in 2016, and the flagship app launched at Mobile World Congress in early 2018. Otter's breakout came with the remote-work surge in 2020, as it pivoted from a mobile recorder into a desktop-integrated meeting assistant. In February 2023 it launched OtterPilot, an AI assistant that joins meetings to capture notes, summaries, and action items.
