In-Depth Review
Otter.ai is a leading product in the speech-to-text space. It focuses on real-time transcription — as you speak, text appears on screen (with about 1-2 seconds of delay). Perfect for journalist interviews, student lectures, and user research interviews: just open Otter nearby, and when finished you have a complete text record + AI auto-generated summary and keywords. Speaker identification can label "who said what." Deep Zoom integration — Otter appears directly in the Zoom sidebar.
🔬 Hands-On Experience
Otter's core positioning is the Zoom-deeply-integrated meeting note taker. Tested for two weeks: after linking Zoom, Otter auto-joined every meeting with real-time transcription display. The Otter Pilot feature is a highlight — even if you miss the meeting, the Bot attends on your behalf and records everything. AI Chat lets you ask questions about meeting content afterward, such as summarizing decisions or extracting action items. Chinese transcription accuracy tested at about 90%, better than Fireflies. However, Otter's cross-platform support isn't as comprehensive as Fireflies — Teams and Webex support is weaker. On the business side, the Free Tier at 300 minutes/month is enough for individual use.
Use Cases
Real-time captions and notes during meetings; auto-generates complete minutes afterward
Pilot auto-joins Zoom meetings, transcribes in real time, and answers questions during the meeting

Centralized management of all meeting recordings and transcriptions; categorized by project or team
Real-time transcription for online courses and lectures; search keywords to locate content during review

Tips & Tricks
1. Use auto-tagging rules — set keywords to auto-tag; e.g., auto-mark as business discussion when price is mentioned
2. Meeting Highlights beat full transcripts — check the highlighted summary first before deciding to review the full text; saves 30 minutes daily
3. Otter Chat is an underappreciated feature — ask what objections the client raised directly after the meeting; no need to re-listen
4. Free Tier gives 300 min/month; enable auto-join only for core meetings to avoid wasting quota on routine syncs

🆚 Comparison
Otter and Fireflies are direct competitors. Otter offers the best experience in the Zoom ecosystem, with Chinese transcription accuracy also leading Fireflies. But Otter's cross-platform integration and search functionality are weaker than Fireflies. If your team primarily uses Zoom, Otter is better; if you use mixed meeting tools (Teams/Meet/Webex), Fireflies is the safer bet. Otter Chat's interactive Q&A; is a differentiating advantage that Fireflies hasn't matched yet.
