Quick Verdict

If you need the most accurate transcription and deep CRM integrations, go with Fireflies. If you want the best free tier and cleanest user experience for small teams, pick Fathom. Otter is a solid middle-ground option if you're already in the Zoom/Google Meet ecosystem and don't need advanced automation.

Overview

AI meeting assistants have become table stakes for ops teams trying to reduce note-taking overhead. These tools join your calls, transcribe everything, generate summaries, and (ideally) push action items into your workflow. The three biggest players—Otter, Fireflies, and Fathom—all do this, but they differ significantly in pricing, accuracy, integrations, and how they handle post-meeting automation.

We tested all three across 20+ meetings (internal standups, client calls, and longer strategy sessions) to see which actually saves time vs. creates more noise. Here's what we found.

Head-to-Head: Otter vs Fireflies vs Fathom

Transcription Accuracy

Fireflies leads here, especially with multiple speakers and accents. Its "Magic" transcription feature catches overlapping speech better than the others. Otter is close behind but struggles with technical jargon (e.g., API names, product terms). Fathom is slightly behind both in raw accuracy, but its summaries are more concise and actionable—it trades granularity for clarity.

Meeting Platform Support

All three support Zoom, Google Meet, and Microsoft Teams. Key differences:

  • Otter has native Zoom integration (bot joins automatically) but requires a Chrome extension for Google Meet.
  • Fireflies supports all three natively plus Webex, RingCentral, and BlueJeans.
  • Fathom works with Zoom, Meet, and Teams but no Webex or niche platforms.

Summaries and Action Items

Fathom wins here. Its AI generates bullet-point summaries with clear action items, decisions, and key questions. You can customize the summary format (e.g., "client-facing" vs. "internal"). Fireflies summaries are good but sometimes include irrelevant filler. Otter summaries are the weakest—often too verbose and missing key decisions.

Integrations and Automation

Fireflies has the deepest integration ecosystem: Salesforce, HubSpot, Slack, Notion, Asana, ClickUp, and more. It also works with Make.com for custom workflows. Fathom integrates with HubSpot, Salesforce, and Slack but has fewer options. Otter integrates with Slack, Google Calendar, and Zoom but lacks CRM depth.

Price Comparison

Tool Free Tier Paid Plans (per user/month) Key Limits
Otter 300 min/month, 30 min/meeting Pro $16.99, Business $30 Free tier limits meeting length to 30 min
Fireflies Unlimited recordings, 800 min storage Pro $10, Business $19, Enterprise custom Free tier has limited AI summaries
Fathom Unlimited recordings, unlimited storage Team $29 (2+ users), Enterprise custom Free tier has no CRM integration

Note: All prices are annual billing. Monthly billing is typically 20-30% higher.

Who Each Is For

Otter

Best for: Teams already using Zoom or Google Meet who want a simple, low-cost transcription tool. Otter's strength is its native integration with these platforms—the bot joins automatically. Weakness: limited automation and CRM features. Good for internal meetings where you just need a transcript, not deep workflow integration.

Fireflies

Best for: Ops teams that need CRM integration and custom automation. Fireflies is the most powerful of the three, especially if you're using Salesforce or HubSpot. Its Make.com integration lets you build complex workflows (e.g., auto-create tasks in Asana when a deal is mentioned). Weakness: the UI can feel cluttered, and the free tier storage limit is restrictive.

Fathom

Best for: Small teams that want the best free tier and cleanest experience. Fathom's unlimited free recordings with no meeting length limit is hard to beat. Its summaries are the most actionable, making it ideal for teams that want to quickly review meetings without reading full transcripts. Weakness: fewer integrations and no Webex support.

Quick Verdict (Expanded)

Choose based on your primary need:

  • Transcription accuracy + CRM: Fireflies
  • Best free tier + clean summaries: Fathom
  • Simple Zoom/Meet integration: Otter

For most ops teams at 1-50 person companies, we recommend starting with Fathom (free) and upgrading to Fireflies if you need CRM automation. Otter is a fine fallback if you're already in its ecosystem, but it's not the best in any single category.
