Otter.ai vs Fireflies.ai: Best AI Meeting Assistant (2026)

TL;DR

Both tools do the same core job: a bot joins your video call, transcribes everything, and hands back a summary with action items. For a firm that records advisory calls, year-end planning sessions, and onboarding meetings, the differences that actually matter are (1) where the notes end up, (2) whether you can search across hundreds of past calls, and (3) what it costs per seat once the whole team is on it. That's where these two diverge.

At a glance

Otter.ai

Strengths

• Slightly higher raw transcription accuracy. Independent 2026 tests put the two within a point of each other (low-94% vs. high-93% word accuracy), but Otter has historically held a small edge on diverse accents and noisy, multi-speaker audio — which describes a lot of year-end planning calls with a couple of partners and a client talking over each other.
• Excellent live transcript UX. The real-time transcript is genuinely useful in the room — you can glance down mid-call and confirm a number was captured correctly, which matters when a client rattles off figures.
• Cheaper entry point billed annually. Pro is $8.33/user/mo on the annual plan, the lowest paid entry price of the two.
• Otter Chat. You can ask questions of a meeting (or your workspace) to pull summaries and answers.

Weaknesses

• Weak native CRM connectivity. Otter offers Salesforce and HubSpot note sync, but it is not built around pushing structured meeting data into a CRM the way Fireflies is. For a firm that runs client relationships through a CRM, this is the deciding gap.
• Tight free-tier and Pro caps. Free is 300 minutes/month with a 30-minute-per-conversation ceiling; Pro is 1,200 minutes/month with a 90-minute cap per meeting. A 100-minute advisory call gets truncated on Pro. You need the Business plan ($30/user/mo monthly) for unlimited monthly minutes and a 4-hour per-meeting cap.
• HIPAA is Enterprise-only, as an add-on. If you handle any health-adjacent client data and need a BAA, that's a custom Enterprise conversation.

Fireflies.ai

Strengths

• Native CRM push at the Pro tier. Fireflies syncs summaries and action items directly onto HubSpot and Salesforce contact, company, and deal records. For an advisory firm, that means a call about a client's S-corp election lands on that client's record automatically — no copy-paste.
• AskFred search across all meetings. You can ask "summarize every action item I committed to with [client] this quarter" or "what did we tell them about the depreciation schedule?" and get an answer pulled from your whole transcript history. This is the feature accountants underrate until they're trying to reconstruct what was promised six months ago.
• Unlimited transcription on every tier, including free. The free plan transcribes unlimited meetings (storage is the limiter at 400 minutes/team); paid tiers lift storage substantially.
• SOC 2 Type II + GDPR on paid tiers. Security posture is documented and standard for firms handling client financial data; HIPAA is available at Enterprise.
• Broad integration surface. 50+ native integrations (Slack, Notion, Asana, Zapier) make it easy to wire action items into whatever workpaper or task system the firm already runs.

Weaknesses

• Marginally lower raw transcription accuracy. The gap is statistical noise in most tests, but if you're transcribing a chaotic four-person call, Otter may win by a hair.
• AI features are credit-metered. AskFred and Smart Highlights consume monthly AI credits (Pro 20, Business 30, Enterprise 50). Heavy users who lean on AI summarization across many calls can hit the ceiling and need to upgrade.
• Storage caps per seat. Pro stores 8,000 minutes/seat; Business and Enterprise are unlimited. A firm recording every client call for years will want Business for the unlimited retention.

Head-to-head

Pricing

The headline prices are close. Otter Pro is $16.99/user/mo (monthly) or $8.33 (annual); Fireflies Pro is $18/user/mo (monthly) or $10 (annual). Both jump to roughly $29–30/user/mo at the Business tier ($19–19.99 annual). The real difference isn't the sticker — it's what you need to pay for to be usable.

On Otter, the Pro plan's 90-minute-per-meeting cap and 1,200-minute monthly cap mean most firms recording full advisory sessions will need Business at $30/user/mo for unlimited minutes and 4-hour meetings. On Fireflies, transcription is unlimited from the free tier up, so Pro at $18/user/mo monthly is genuinely workable for a small firm — the upgrade to Business is about storage retention and more AI credits, not about being able to record a long call at all. For a 5-person firm running long client calls, that's the difference between ~$1,800/year (Fireflies Pro annual) and ~$1,200/year (Otter Business annual) — with Fireflies giving you the CRM push that Otter's cheaper-looking entry tier doesn't.

AI / Automation features

Both extract action items and generate summaries competently. The separator is search and routing:

• AskFred (Fireflies) answers questions across your entire meeting history. For a firm, your call archive becomes a queryable record of what was advised and agreed — useful for both client service and your own defensibility.
• Native CRM automation (Fireflies) turns the summary into a CRM activity automatically. Otter's CRM connection is shallower — you can sync notes, but it's not the same as Fireflies dropping structured action items onto the right deal record.

Otter's automation is competent but Otter-centric; the value tends to stay inside Otter. Fireflies is designed to fling the output into the tools you already run the firm on.

Integrations

This is the clearest win for Fireflies. It natively connects to HubSpot, Salesforce, Pipedrive, Slack, Notion, Asana, ClickUp, Zapier and 50+ more. Otter covers Zoom, Google Meet, Teams, Slack, Dropbox and offers Salesforce/HubSpot note sync, but it does not match Fireflies' CRM depth. If your firm's client records live in HubSpot or Salesforce, Fireflies is the tool that keeps those records current without manual work.

On meeting platforms, the two are effectively tied: both cover Zoom, Google Meet, and Microsoft Teams, which is the entire field for almost every accounting firm.

Customer support

Both run standard SaaS support: help center, email/ticketing on lower tiers, with prioritized support and onboarding at higher tiers. Neither has a support story compelling enough to be a deciding factor. Both have large user bases and active review presence (G2, Capterra), so you'll find peer answers for most setup questions.

Our pick

For most accounting, bookkeeping, and advisory firms, Fireflies.ai is the better choice. The reason is specific to how a firm operates: your value is in what you advise and what you commit to, and both tools capture that — but only Fireflies makes it (1) automatically land on the right client record in your CRM, and (2) searchable across your entire history with AskFred. When a partner asks "what did we tell the Hendersons about their estimated payments in Q1?", that's a 10-second AskFred query, not an afternoon of scrubbing recordings. And because transcription is unlimited from the free tier up, you're not forced onto the most expensive plan just to record a long call.

The action-item-into-workpaper workflow matters here. A Fireflies Super Summary with extracted action items pushes cleanly into a task system (Asana, ClickUp, or via Zapier into your practice-management tool), so "follow up on the depreciation election" becomes a tracked task instead of a line in a transcript nobody reopens. That defensible, searchable documentation trail is exactly what an advisory firm wants when a client later disputes what was discussed.

The only times we'd recommend Otter.ai instead:

• You record mostly in-room or hybrid meetings where the live, real-time transcript on screen is genuinely useful during the conversation — Otter's live UX is better.
• You don't run a CRM (or don't route client work through one) and just want clean transcripts and summaries — Otter's slightly higher raw accuracy and lower annual entry price win on that narrower job.
• Transcription accuracy on messy multi-speaker audio is your single top priority and you're willing to handle routing manually.

Frequently Asked Questions

Is Otter.ai or Fireflies.ai more accurate?

They're close. Independent 2026 tests put word-level accuracy within roughly one point of each other (low-94% vs. high-93%), which is statistical noise for most meetings. Otter has historically held a slight edge on noisy, multi-speaker audio and diverse accents. For a typical advisory call, the difference won't change your decision — integration depth and search will. Test both on your own recordings if accuracy is your top concern.

Which is better for an accounting or bookkeeping firm specifically?

Fireflies, in most cases. Accounting and advisory work is relationship-driven and documentation-heavy: you need notes on the right client record, action items that become tracked tasks, and the ability to search "what did we advise" months later. Fireflies' native CRM push (HubSpot, Salesforce) and AskFred search across your whole meeting library serve that workflow directly. Otter is the better pick only if you don't use a CRM and just want clean transcripts.

Do both integrate with HubSpot and Salesforce?

Both touch both, but not equally. Fireflies has deep native CRM integrations that sync summaries and action items onto contacts, companies, and deals automatically. Otter offers Salesforce and HubSpot note sync, which is shallower. If keeping client records current automatically is the goal, Fireflies is the stronger integration.

Are these tools secure enough for client financial data?

Fireflies advertises SOC 2 Type II and GDPR compliance on its paid tiers, with HIPAA available at Enterprise. Otter uses TLS and AES-256 encryption across tiers, adds SSO/SCIM on Business and up, and offers HIPAA as an Enterprise add-on. For a firm handling sensitive client data, get the data-processing terms and retention policy in writing, confirm who at the vendor can access transcripts, and — if you have any health-adjacent data — confirm the BAA/HIPAA path before recording client calls.

Do I need the most expensive plan to record long client calls?

On Fireflies, no — transcription is unlimited even on the free tier, and Pro ($18/user/mo monthly) handles long calls; you upgrade mainly for storage retention and AI credits. On Otter, effectively yes — Pro caps meetings at 90 minutes and 1,200 minutes/month, so firms recording full sessions usually need Business ($30/user/mo monthly) for unlimited minutes and a 4-hour per-meeting cap. Factor that into the real per-seat cost rather than comparing entry prices.

Can I switch from Otter to Fireflies (or back) later?

Yes, but plan for it. Both let you export transcripts, and switching the recording bot is trivial. The friction is your back history: search, summaries, and any CRM-linked notes live inside whichever tool created them. Export your transcript archive before cancelling, and don't expect AskFred-style historical search to carry over — you'd be starting that library fresh in the new tool.
