Best AI Meeting Assistant 2026: Fathom vs Otter vs Fireflies vs Subanana

The short answer: for English-only meetings inside a US workplace stack, Otter or Fathom is usually the fastest path, and Fireflies is the better fit if your day runs through a CRM. If your meetings include Cantonese, Mandarin, or other Asian languages — or you want to choose the model that writes your summary — that is where Subanana earns its place. This comparison sources every pricing and feature claim from each tool's published documentation, pulled in June 2026. No fabricated head-to-head accuracy scores: each tool below has a free tier or trial, so the only accuracy test that counts is the one you run on your own audio.

Disclosure: I run Subanana, so treat the Subanana section as the one with a thumb on the scale and check the linked docs for everything else. Every competitor below gets a clearly-stated "best for" and a "where it's the wrong fit," including Subanana.

What does an AI meeting assistant actually do?

An AI meeting assistant joins (or records) your calls, produces a transcript, and turns that transcript into a usable artifact — a summary with decisions and action items you can paste into a doc or a ticket. All four tools here do that core loop. They differ on five things that actually decide the buy:

• Capture model — a bot that visibly joins the call, a bot-free desktop capture, or both.
• Language coverage — how many languages, and crucially which ones (English-only versus genuine Asian-language support).
• Summary AI — a single fixed model, or a choice of models per meeting.
• Integrations — where the notes land afterward (CRM, Slack, your own AI chat).
• Pricing shape — per-user seats versus a workspace model, and what the free tier actually unlocks.

The rest of this post walks each tool against those five, then a full comparison table, then a "which should you pick" by buyer profile.

1. Fathom — best for free, frictionless individual capture

What it is: A meeting notetaker that leans hard on a generous free tier. Fathom's pricing page lists the Free plan as "Unlimited recordings + transcriptions" with "Instant AI call summaries" — unusually open for a free tier in this category. Paid tiers are Premium at $20/user/mo ($16 annual), Team at $19/user/mo ($15 annual, 2-user minimum), and Business at $34/user/mo ($25 annual).

Where it's stronger: The free tier is the standout — unlimited recording and transcription with no meeting cap. Fathom recently added a bot-free capture mode, which their pricing page marks as a beta feature for Mac ("Choice of bot-free* or bot capture type (*in beta)"). It also ships first-class ChatGPT and Claude integrations plus Slack, no-code automation integrations, a public API, and CRM syncs, per the same page. On languages, Fathom's help center states it "supports transcripts in 38 languages" with automatic language detection.

Where it's the wrong fit: Fathom groups Chinese as a single entry and does not list Cantonese as a distinct language in its help documentation, so HK and pan-Cantonese teams can't rely on it for colloquial Cantonese output. The bot-free capture being in beta (and Mac-only) also means the headline "no bot" experience isn't yet the stable default for everyone.

Honest win to concede: Fathom's free tier is the most generous of the four for an individual who just wants unlimited recordings and summaries at zero cost.

2. Otter — best for English-first US workplace teams

What it is: One of the most established AI meeting assistants in English-speaking markets, built around its AI Meeting Agent (OtterPilot) and Otter AI Chat. Otter's pricing page lists a Free (Basic) plan with 300 monthly transcription minutes, a 30-minute cap per conversation, and 3 lifetime file imports; Pro at $16.99/user/mo ($8.49 annual) with 1,200 monthly recording minutes; and Business at $30/user/mo ($19.99 annual) with unlimited meetings.

Where it's stronger: Otter is purpose-built for the US workplace stack — native Zoom, Google Meet, Microsoft Teams, and Slack capture, plus Salesforce and HubSpot logging on paid tiers, per its pricing and integrations pages. Otter AI Chat answers questions across your meetings, and ChatGPT and Claude can pull meeting knowledge through Otter's MCP server. There's also a desktop app for bot-free meetings and live transcription.

Where it's the wrong fit: Language coverage is narrow. Otter's pricing page states transcription "in English, Spanish, French, German, Japanese, and Chinese" — six languages — and its help center notes German and Chinese are still being rolled out. The Chinese support is Simplified, with no Cantonese option, so it's a poor match for HK / Cantonese-heavy meetings. The free tier's 300-minute monthly cap is also tight for daily use.

Honest win to concede: For pure-English teams already living in Zoom + Salesforce + HubSpot, Otter's integration depth and brand maturity are hard to beat.

3. Fireflies — best for CRM-driven sales and revenue teams

What it is: A meeting assistant positioned around team conversation intelligence and CRM workflows. Fireflies' pricing page lists a Free plan ($0) with unlimited transcription and 800 minutes of storage per seat; Pro at $18/seat/mo ($10 annual) with 8,000 minutes of storage; Business at $29/seat/mo ($19 annual) with unlimited storage; and Enterprise at $39/seat/mo (annual).

Where it's stronger: Fireflies markets the broadest language headline of the four — "transcription in 100+ languages" with auto-language detection, per its pricing page. It's built for revenue teams: conversation analytics, a recently launched Live Assist and desktop app, and deep integration coverage. It also exposes an API for processing audio files and pushing notes into work tools.

Where it's the wrong fit: The "100+ languages" headline doesn't translate into Cantonese granularity — Fireflies' API language-codes documentation lists a single Chinese entry (zh) with no distinct Cantonese option, and its own docs note that handling multiple languages within one meeting is a separate, beta-stage Multi-Language Mode. Storage on the Free and Pro tiers is also metered per seat (800 and 8,000 minutes respectively), so heavy recorders hit a ceiling.

Honest win to concede: If your workflow is "meeting → CRM activity log → coaching review," Fireflies' conversation-intelligence layer and integration breadth are purpose-built for that loop.

4. Subanana — best for Asian-language meetings and model-flexible summaries

What it is: An AI speech-to-text platform whose meeting mode captures Google Meet and Microsoft Teams calls via a bot that joins from your connected calendar, then produces a tidied transcript plus a summary with decisions and action items after the meeting ends.

Where it's stronger: Two things, both relevant to readers the other three underserve.

• Asian-language coverage with per-language model routing. Subanana supports 80+ languages and continuously benchmarks speech-to-text models, routing each transcription to the best-performing model for that source language. Cantonese (both colloquial and Standard Written Chinese as separate output options) and Mandarin are first-class, not grouped under a single "Chinese" entry. For a sense of the surface, see the Chinese transcription tool.
• A choice of summary model per meeting. Subanana's meeting summary is the one place where you pick the model — a three-tier menu of multiple frontier models, with the lineup updated as stronger models ship. You're not locked to one provider's summary style. You can also chat with the transcript directly to ask "what did we decide about X" or "who owns Y."

On capture, the meeting transcription tool handles Google Meet and Teams, including hybrid meetings where some attendees are in a room and some are remote — the in-platform bot receives both audio streams without any virtual-audio-cable setup.

Where it's the wrong fit: Be clear-eyed about three gaps:

• No Zoom bot. Subanana captures Google Meet and Microsoft Teams only. If your team lives in Zoom, Otter, Fathom, and Fireflies all cover it and Subanana does not.
• No native CRM push. There's no Salesforce / HubSpot field sync and no Slack / Notion push-out. Notes live in Subanana with export (SRT, VTT, TXT, DOCX, XLSX, Markdown) and in-app AI chat — but if you need meeting data flowing automatically into a CRM, Fireflies and Otter win.
• The meeting bot is post-production, not live. It records and summarizes after the call; it does not display live captions during the meeting. (Subanana does offer real-time captioning as a separate microphone-input feature for live events — not via the meeting bot.)

Honest win to concede to the field: none of the four is a universal winner. The three above beat Subanana on Zoom coverage and CRM integration depth; Subanana's edge is Asian-language meetings and summary-model choice.

How do the four AI meeting assistants compare side by side?

Every figure below is from each tool's published documentation (June 2026). Prices are per user/seat unless noted; annual figures in parentheses.

A few notes on reading this table honestly. The language counts are vendor headlines, not audited benchmarks — "100+" and "80+" are marketing numbers, and the only column that's been checked against primary docs is the Cantonese row, because that's the one that actually separates these tools for an Asian-language buyer. And "fixed" summary model isn't a knock — a single well-tuned model is fine for most English meetings; model choice matters most when you're summarizing in a non-English language where one model may handle the nuance better than another.

Which AI meeting assistant should you pick?

Match the tool to the shape of your meetings, not to a feature count:

• You want unlimited free recording for yourself → Fathom. The free tier is the most generous here.
• You're an English-only team inside Zoom + Salesforce + HubSpot → Otter. Mature, deep US-stack integrations.
• You're a sales/revenue team that lives in a CRM → Fireflies. Conversation analytics and integration breadth built for that loop.
• Your meetings include Cantonese, Mandarin, or other Asian languages, or you want to choose the summary model → Subanana. 80+ languages with per-language model routing and a user-selectable summary menu.
• You're on Zoom and that's non-negotiable → any of Fathom, Otter, or Fireflies. Subanana doesn't run a Zoom bot.

If you run meeting transcription across mixed-language calls, the honest test is to record the same meeting in two tools' free tiers and compare the transcripts and summaries on your own audio. That's the only accuracy comparison that survives contact with your real meetings.

Frequently asked questions

Which AI meeting assistant has the best language support? By raw vendor headline, Fireflies claims the most (100+ languages) and Subanana lists 80+, while Fathom states 38 and Otter six. But headline counts hide the detail that matters for Asian-language teams: only Subanana treats Cantonese as a distinct language (in both colloquial and Standard Written Chinese output). Fathom, Otter, and Fireflies each group Chinese as a single entry with no Cantonese option, per their published docs.

Do these tools work with Zoom? Fathom, Otter, and Fireflies all capture Zoom meetings. Subanana captures Google Meet and Microsoft Teams only — it does not run a Zoom bot, so it's the wrong choice if Zoom is your primary platform.

Is there a free AI meeting assistant? All four have a free tier, but they differ sharply. Fathom offers unlimited free recordings and transcriptions; Fireflies offers unlimited transcription with 800 minutes of storage per seat; Otter caps the free tier at 300 minutes per month and 30 minutes per conversation; Subanana's free tier is a watermarked preview (first 5 minutes) with export reserved for paid plans.

Can I choose which AI model writes the summary? Only on Subanana, where the meeting summary uses a three-tier menu of selectable frontier models. Fathom, Otter, and Fireflies each use a fixed summarization model. Note that on Subanana the model choice applies to the summary specifically — transcription and translation are routed automatically to the best-benched model per language.

Can an AI meeting assistant caption a live event in real time? The meeting bots in all four tools are oriented around recording and post-meeting summarization. If you need captions displayed live during an event, Subanana offers a separate real-time captioning feature that takes direct microphone or system audio and shares an audience-facing link — distinct from the meeting bot, which produces its transcript after the call ends.

Pick the tool that fits the shape of your meetings. If those meetings are English-only and CRM-bound, the established players have you covered. If they're multilingual — especially Cantonese or other Asian languages — or you want to pick the model that writes your summary, try Subanana's meeting mode on your next call and compare the transcript and summary against whatever you use today. Full plan details are on the pricing page.
