Before we dive into individual tools, let's establish the criteria. After testing these tools for months, here's what actually matters — and what's just marketing fluff.
If the transcript is wrong, nothing else matters. We test accuracy with accents, technical jargon, overlapping speakers, and poor audio quality. Fireflies and Sembly consistently score above 95%. Otter is close behind at ~93%. The gap matters when you're searching transcripts weeks later.
A transcript you can't search is almost useless. Fireflies dominates here — its global search across all meetings with smart filters (speaker, date, topic, action items) is genuinely best-in-class. Sembly offers solid search. Otter and MeetGeek are adequate but less powerful.
The whole point is saving time after meetings. Sembly.ai excels here — its AI-generated summaries are remarkably insightful, often catching nuance humans miss. Fireflies produces solid, structured summaries. Otter's summaries are adequate but sometimes miss key decisions.
An AI assistant that doesn't plug into your workflow creates more work. Fireflies integrates with 30+ platforms (Zoom, Teams, Google Meet, Slack, Salesforce, Notion). Sembly covers the major video conferencing tools. Krisp works at the audio level — it integrates with everything because it processes sound before it reaches any app.
Free tiers vary dramatically. Fireflies offers unlimited transcription on its free plan (limited AI features). Otter gives 300 minutes/month free. Sembly's free tier is limited but its paid plans start reasonably. Krisp's free tier is generous for noise cancellation. Always check current pricing — it changes frequently.
Your meetings contain sensitive information. Fireflies and Sembly are SOC 2 compliant. Krisp processes audio locally (strong privacy). Otter stores transcripts in the cloud. If you're in healthcare, legal, or finance, verify compliance before choosing. None of these tools should be treated as HIPAA-compliant without explicit verification.
Fireflies is the most complete AI meeting assistant on the market. It joins your meetings automatically (Zoom, Teams, Google Meet, Webex), transcribes with 96%+ accuracy, and builds a searchable meeting knowledge base. The killer feature is global search — you can find any conversation from any meeting, months later, in seconds.
Strengths: Best integrations ecosystem (30+), unlimited free transcription, excellent search, solid mobile app, conversation intelligence features for sales teams.
Weaknesses: AI summaries sometimes too generic, UI can feel cluttered with many meetings, premium features locked behind higher tiers.
Try Fireflies.ai Free → Read full reviewSembly.ai is the smartest tool when it comes to understanding what actually happened in your meetings. Its AI doesn't just transcribe — it analyzes. It identifies decisions, detects tasks, tracks topics across multiple meetings, and generates meeting summaries that feel like they were written by a thoughtful human note-taker.
Strengths: Best-in-class AI summaries, task detection that actually works, topic tracking across meetings, solid Slack/Teams integration, good for recurring meetings.
Weaknesses: Fewer integrations than Fireflies, no free unlimited tier, UI can be less intuitive, smaller user community.
Try Sembly.ai Free → Read full reviewOtter.ai is the most user-friendly option and offers the best free tier with 300 monthly transcription minutes. It's excellent for individuals and small teams who need reliable real-time transcription without complexity. The mobile app is particularly strong for in-person meetings.
Strengths: Generous free tier (300 min/month), excellent real-time transcription, best mobile app, collaborative note-editing, OtterPilot for auto-join.
Weaknesses: Limited integrations compared to Fireflies, AI features less sophisticated, fewer enterprise features, search less powerful.
Try Otter.ai Free → Read full reviewKrisp.ai takes a fundamentally different approach — it works at the audio level, removing background noise before it reaches any app. This means it works with literally everything: Zoom, Teams, Google Meet, Discord, phone calls. If you work in a noisy environment, Krisp is almost magical.
Strengths: Incredible noise cancellation (dogs barking, construction, coffee shops), system-wide operation, also offers transcription, local audio processing (privacy win).
Weaknesses: Not a full meeting assistant, transcription features are newer/less mature, free tier limited for transcription, no meeting search/memory features.
Try Krisp.ai Free →MeetGeek is the value play — it offers solid transcription and meeting summaries at a lower price point than competitors. It auto-records and auto-joins meetings like the others, and the interface is clean and straightforward.
Strengths: Affordable team pricing, clean UI, auto-recording works reliably, decent meeting summaries, good for budget-conscious teams.
Weaknesses: Fewer integrations, smaller feature set, transcription accuracy slightly below leaders, less advanced AI analysis.
Try MeetGeek.ai Free →Start with Otter.ai (best free tier with 300 min/month) or Fireflies.ai (unlimited free transcription). Both give you real value without paying. If you need the smartest summaries, Sembly.ai is worth the upgrade.
Fireflies.ai is the clear winner — searchable meeting memory across your whole team is transformative. The Business plan ($19/seat/month) unlocks conversation intelligence that pays for itself. If budget is the main concern, MeetGeek.ai offers solid team plans for less.
Fireflies.ai again — its conversation intelligence features (talk-to-listen ratio, sentiment tracking, competitor mentions) are built for revenue teams. Sembly.ai is strong here too, especially for analyzing discovery calls and tracking deal-specific topics across meetings.
Get Krisp.ai first — it will improve every single call regardless of which meeting tool you use. Then layer on Fireflies or Sembly for transcription and summaries. Krisp + Fireflies is a powerful combo.
Sembly.ai is unmatched here. Its AI identifies decisions, detects tasks, and tracks topics across meetings. If your meetings are strategic (board meetings, planning sessions, client workshops) rather than routine stand-ups, Sembly's analysis justifies its cost.
Verify compliance before choosing. Krisp.ai processes audio locally (best for privacy). Fireflies and Sembly are SOC 2 compliant but store data in the cloud. Always check with your compliance team — none of these tools are HIPAA-compliant out of the box.
Fireflies.ai offers unlimited transcription on its free plan (limited AI features). Otter.ai gives 300 minutes/month with real-time transcription. If you have many meetings, Fireflies gives more volume. If you want live transcription, Otter is better. Both are genuinely useful for free.
Yes — Fireflies, Sembly, Otter, and MeetGeek all support auto-join for Zoom, Google Meet, and Microsoft Teams. You connect your calendar and the bot joins automatically. Krisp doesn't join meetings — it processes your audio locally.
It depends on the tool. Krisp processes audio locally on your device (strongest privacy). Fireflies and Sembly are SOC 2 compliant and encrypt data in transit and at rest. However, transcripts are stored on their servers. If you handle highly sensitive information, check with your security team and consider local-processing options.
Very. The best tools (Fireflies, Sembly) achieve 95-97% accuracy in good conditions. Accuracy drops with heavy accents, poor audio, overlapping speakers, or technical jargon. No tool is 100% accurate — always review critical sections manually.
Yes, and many teams do. A common setup: Krisp for noise cancellation + Fireflies for transcription/search. Or Otter for real-time notes + Sembly for post-meeting analysis. Just be aware that having multiple bots join the same meeting can look odd to external participants.
Fireflies supports 60+ languages, Otter supports English primarily, Sembly supports major European languages. Krisp's noise cancellation is language-agnostic (it works on audio, not text). If you need multilingual support, Fireflies has the broadest coverage.
We don't just read marketing pages. Here's how we actually evaluate these tools.
Real meetings, not scripted demos. Including noisy environments and multiple accents.

Most teams should start with Fireflies.ai — it's the most complete platform and the free tier lets you test thoroughly before committing. If your meetings are strategic and you need the smartest analysis, Sembly.ai is worth every penny. And if background noise is your #1 problem, Krisp.ai solves it instantly.
The good news: there's no wrong choice among the top four. They all deliver real value. Pick the one that matches your biggest pain point and run it for a week. You'll know quickly if it's right.
