Otter.ai vs Fireflies.ai: Which Meeting Notes Tool Wins for PMs?

Otter.ai

Best for PMs who want the best live transcription with slide capture and real-time speaker ID during meetings. Free tier; Pro from $16.99/mo.

Fireflies.ai

Best for PMs who want deep cross-meeting search (AskFred), conversation analytics, and 60+ integrations including Jira and Notion. Free tier; Pro from $18/mo.

Otter: Otter's live transcription is an advantage during discovery calls — you can reference what was said in real time and know you won't miss a quote. The automated slide capture is less relevant for interviews (customers rarely present slides), but the AI Chat lets you ask “what did they say about pricing?” right after the call. The tradeoff is the visible bot: some enterprise customers block third-party meeting bots, and the “Otter has joined” notification can shift the tone of a candid conversation.

Fireflies: Fireflies also sends a bot, but its strength is post-call analysis. The AI summary captures pain points, feature requests, and sentiment — and the conversation analytics track talk time (are you talking more than the customer?) and question count, which is a useful self-coaching tool for discovery interviews. AskFred lets you search across all your discovery calls: “What did enterprise customers say about onboarding in the last 30 days?” The 60+ integrations mean call summaries flow into your CRM automatically.

Fireflies wins on discovery calls because conversation analytics (talk time, question count) coach better interview technique, and cross-meeting search with AskFred clusters insights across multiple customer calls — both critical for PM discovery workflows.

Otter: This is where Otter's slide capture shines. On roadmap reviews where slides are presented, Otter aligns each slide with the transcript timeline — so you can jump to exactly what was said about slide 7 (the pricing-change proposal). The AI summary captures key decisions. For PMs who present roadmap slides to leadership, this slide-to-transcript alignment is a genuine advantage that Fireflies doesn't offer.

Fireflies: Fireflies handles stakeholder reviews well with its AI summary capturing decisions, action items, and key topics. The action items sync to Jira, Asana, or Notion via integrations, so follow-ups don't get lost. But without slide capture, you lose the visual context of what was presented — you get the transcript but not the alignment between slides and discussion.

Otter wins on stakeholder reviews because slide-to-transcript alignment is a genuine advantage when presenting roadmap decks — you can trace exactly what was said about each slide, which Fireflies can't match.

Otter: Otter AI Chat lets you ask questions within a meeting or across meetings on paid plans. You can search your meeting history conversationally. It's useful for PMs who sit in many meetings and need to recall what was decided — but the search is scoped to Otter's transcription and summary data, not enriched with conversation analytics.

Fireflies: AskFred is Fireflies' cross-meeting AI assistant, and it's one of the strongest in the category. It uses semantic search across all your meetings — not just keyword matching — so you can ask “What commitments did we make about the API redesign this quarter?” and get a synthesized answer with source citations. Combined with the 60+ integrations, AskFred turns your meeting history into a queryable knowledge base that flows into your project management and CRM tools.

Fireflies wins on cross-meeting search because AskFred's semantic search is deeper and more flexible than Otter AI Chat, and the integration ecosystem means answers flow into the tools where work actually happens.

Otter: Otter's live transcription is its signature feature and the best in the category. The transcript updates in real time during the meeting with speaker identification, so you can see exactly who said what as it happens. For PMs who want to reference a point mid-meeting, confirm a commitment in real time, or share the live transcript with a remote participant, Otter's in-meeting experience is unmatched.

Fireflies: Fireflies offers real-time transcription too, but the in-meeting display is less polished than Otter's. Fireflies is more optimized for post-call analysis than in-meeting viewing. During the meeting, the bot captures everything, but you're more likely to review the transcript and summary afterward rather than watching it live. For PMs who need the best live experience, Fireflies is adequate but not best-in-class.

Otter wins on live transcription because best-in-class real-time display with speaker ID is its core differentiator — a fundamentally in-meeting experience that Fireflies treats as secondary.

Otter: Otter offers basic talk-time tracking on the Business plan, but it doesn't go deep into conversation analytics. If you want to know whether your discovery calls are balanced (are you listening more than talking?), Otter gives you the transcript but not the metrics to self-assess your meeting behavior.

Fireflies: Fireflies' conversation analytics are a standout feature for PMs. It tracks talk time per speaker, sentiment trends, filler word frequency, question count, and monologue detection. For PMs running customer interviews, the talk-time metric is a genuine self-coaching tool — if you're talking 70% of a discovery call, that's a problem. The sentiment analysis tracks whether a conversation trended positive or negative, useful for stakeholder reviews and customer calls alike.

Fireflies wins on conversation analytics because talk time, sentiment, and question tracking are real PM coaching tools — Otter's basic talk-time tracking doesn't compare.

Otter: Otter integrates with Salesforce, HubSpot, Microsoft, Slack, and more. The CRM sync is solid for customer-facing teams. But the integration count is smaller than Fireflies', and the automation options are more limited — you get the integrations but less flexibility in how meeting data flows into your downstream tools.

Fireflies: Fireflies offers 60+ integrations — the widest ecosystem among AI meeting notes tools. Salesforce, HubSpot, Slack, Notion, Jira, Asana, ClickUp, Zapier, and more. For PMs, the Jira and Asana integrations mean action items from sprint planning flow directly into your backlog. The Notion integration means meeting summaries land in your project docs. The Zapier integration opens up unlimited automation paths. This is the broadest workflow automation surface in the category.

Fireflies wins on integrations because 60+ connectors — including Jira, Asana, Notion, and Zapier — create the widest automation surface for PM workflows, far beyond Otter's narrower ecosystem.

Which is better for product managers: Otter.ai or Fireflies.ai?

It depends on your workflow. If you want the best live transcription with slide capture for customer-facing meetings and stakeholder reviews, Otter.ai is the stronger choice. If you want deep cross-meeting search (AskFred), conversation analytics (talk time, sentiment), and the widest integration ecosystem (60+ connectors including Jira, Asana, and Notion), Fireflies.ai is better. Both have free tiers — try each on your real meetings before committing. For the full meeting notes landscape, see our AI meeting notes tools for product managers guide.

Is Otter.ai or Fireflies.ai cheaper?

Otter's Pro plan is $16.99/month and Fireflies' Pro plan is $18/month — Otter is slightly cheaper. But Fireflies offers a more generous free tier: 800 minutes/month with unlimited meetings vs Otter's 300 minutes/month and 3 meetings. At the Business tier, Fireflies is $29/seat/mo vs Otter's $30/seat/mo. The pricing difference is negligible — the real differentiator is what each tier includes, not the headline price. For free-tier limits across all PM AI tools, see our free AI tools for product managers guide.

Do Otter and Fireflies both put a bot in my meeting?

Yes. Both Otter and Fireflies send a bot that joins your call as a visible participant (labeled 'Otter' or 'Fred'). This is different from bot-free tools like Granola, which captures audio locally without joining the call. The bot approach works well for internal meetings, but some enterprise customers block third-party meeting bots. For external customer calls where a visible bot is a concern, consider a bot-free alternative. See our Otter.ai alternatives and Fireflies.ai alternatives pages for options.

Which has better cross-meeting search: Otter or Fireflies?

Fireflies.ai has the stronger cross-meeting search. AskFred uses semantic search across all your meetings — you can ask 'What commitments did we make about the API redesign this quarter?' and get a synthesized answer with source citations. Otter AI Chat also supports cross-meeting questions on paid plans, but it's scoped to Otter's transcription and summary data without the semantic depth of AskFred. Combined with Fireflies' 60+ integrations, cross-meeting insights flow directly into your project management and CRM tools.

Can I upload audio files to Otter or Fireflies?

Fireflies.ai supports uploading any audio or video file for post-hoc transcription and analysis — useful for PMs who record calls with tools that don't support live bots, or who want to transcribe recorded webinars and conference talks. Otter.ai is primarily designed for real-time capture and offers limited audio upload functionality. If you frequently work with pre-recorded audio, Fireflies is the better choice.

Which has better integrations for PM workflows: Otter or Fireflies?

Fireflies.ai has the wider integration ecosystem with 60+ connectors, including Jira, Asana, Notion, ClickUp, Zapier, Salesforce, HubSpot, and Slack. For PMs, the Jira and Asana integrations mean sprint planning action items flow directly into your backlog. Otter.ai integrates with Salesforce, HubSpot, Microsoft, and Slack — solid for CRM-centric teams but a narrower ecosystem overall. If your PM workflow runs through Jira, Asana, or Notion, Fireflies has the edge.

What's the best AI meeting notes tool for PMs overall?

Otter and Fireflies are two of the best, but they're not the only options. Granola offers bot-free capture with customizable templates (best for Mac PMs). Fathom offers instant highlight clips and is free for individuals. Read.ai adds conversation analytics and talk-time coaching.
