Cluely vs Otter.ai: Why Real-Time Beats Post-Meeting

Most AI meeting tools record what happened. Cluely tells you what to say while it's happening. That's not an incremental improvement — it's an entirely different product category.

Otter.ai built a strong business around post-meeting transcription. Millions of users rely on it. But the assumption underneath Otter — that the most valuable moment to receive AI help is after a conversation ends — is starting to crack.

TL;DR

• Otter.ai transcribes and summarizes meetings after they happen. It requires a bot to join your call. Pricing starts at ~$17/month.
• Cluely provides real-time AI answers, coaching, and context during your meeting through an invisible desktop overlay. No bot. Pricing starts at $20/month (Pro) or $75/month with full undetectability.
• If you need a searchable archive of past meetings, Otter is excellent. If you need to perform better in the meeting itself, Cluely is built for that.
• The market is shifting from "record everything" to "help me now." Cluely is on the right side of that shift.

What Each Tool Actually Does

Otter.ai: The Transcription Workhorse

Otter.ai has been around since 2016. It joins your Zoom, Teams, or Google Meet call as a visible bot participant, records the audio, and produces a searchable transcript with speaker identification, action items, and summaries. After the meeting ends, you get a polished recap you can share with your team.

It's good at what it does. Otter's transcription accuracy is solid, its integrations run deep (Salesforce, HubSpot, Slack), and its search across past meetings is genuinely useful for teams that produce dozens of calls per week.

The core limitation: Otter is a historian. It tells you what happened. It doesn't help you while it's happening.

Cluely: Real-Time Intelligence Layer

Cluely is a desktop application (Mac and Windows) that runs as an overlay on your screen during any virtual call. It captures your screen content via OCR and your audio via speech-to-text, then feeds both into GPT-4-class models to generate contextual suggested responses in roughly 300 milliseconds.

No bot joins your call. No one on the other end knows it's there. The overlay is invisible to screen-sharing software on Zoom, Teams, Meet, Webex, RingCentral, and Slack — which is the entire point of the $75/month "Undetectable" tier.

Beyond live answers, Cluely also generates meeting notes, drafts follow-up emails, and runs pre-call intelligence on your meeting participants (pulling context from LinkedIn and past conversations). But the real-time coaching is the headline feature — and the reason the comparison with Otter breaks down quickly.

The Paradigm Split: During vs. After

This is the core architectural difference, and it matters more than any feature comparison table.

Otter's model: Record → Transcribe → Summarize → Deliver after the call.

Cluely's model: Listen → Understand → Suggest → Deliver during the call.

These aren't competing approaches to the same problem. They're solving different problems entirely.

Consider a sales call. With Otter, you get a transcript afterward that tells you the prospect mentioned budget concerns at minute 14. Useful for your CRM notes. With Cluely, you get a suggested response to those budget concerns at minute 14, while the prospect is still on the line and the deal is still live.

Or consider a job interview. Otter gives you a record of what was asked. Cluely gives you a structured answer framework the moment the interviewer finishes their question — with 95% transcription accuracy across 12+ languages feeding the suggestion engine.

The after-the-fact summary is helpful. The in-the-moment intelligence is transformative. One improves your documentation. The other improves your performance.

The Bot Problem

Here's where things get uncomfortable for Otter and every traditional meeting recorder.

Otter requires a bot to join your call. That bot shows up as a participant. Everyone in the meeting sees it. In a casual internal standup, nobody cares. In a high-stakes sales negotiation? In a sensitive HR conversation? In a job interview where you're being evaluated?

The bot changes the dynamic. People speak differently when they know they're being recorded by an identifiable third-party tool. Sales prospects get guarded. Interview candidates get self-conscious. Executives sanitize their language.

Cluely doesn't have this problem because Cluely doesn't join your call. It runs locally on your machine, processing your screen and audio without any external participant, any recording notification, or any visible footprint.

This is a deliberate architectural choice, not a technical limitation. Cluely was built from the ground up to be invisible. The Undetectable tier ($75/month) specifically ensures the overlay can't be detected by screen-sharing APIs — a feature that's polarizing by design but solves a real user problem.

We wrote more about this shift in Why Meeting Bots Are Dead — the short version is that the "bot in the call" model is hitting adoption ceilings precisely because it introduces social friction that undermines the tool's value.

For teams that want AI meeting notes without a bot, the invisible overlay approach eliminates the biggest barrier to adoption.

Feature-by-Feature Comparison

Otter wins on post-meeting collaboration features: shared workspaces, searchable archives, and CRM integrations are mature and well-built. If your workflow revolves around reviewing past conversations as a team, Otter has a clear edge.

Cluely wins on everything that happens during the conversation: real-time suggestions, screen awareness, pre-call research, follow-up drafting, and invisibility. If your priority is performing better in the moment, Cluely is purpose-built for that.

Pricing: What You're Actually Paying For

Cluely Pricing

No annual pricing is published. No free trial is mentioned. Enterprise deals exist but aren't publicly listed — though at least one public company signed a $2.5M annual contract.

Otter.ai Pricing

Otter is cheaper at the entry level ($17 vs. $20 for comparable paid tiers) and offers annual billing discounts that Cluely doesn't. For budget-conscious individuals who primarily need transcription, Otter delivers more value per dollar.

But this is a misleading comparison. You're not choosing between two versions of the same thing. Otter's $17/month buys you post-meeting transcription. Cluely's $20/month buys you real-time AI coaching. The $75/month Undetectable tier buys you that coaching with zero visible footprint. These are different products at different price points solving different problems.

If you need both — real-time help and a searchable transcript archive — you could run both. They don't conflict. But if you're choosing one, the question isn't "which is cheaper?" It's "where do I need help: before the meeting ends, or after?"

Who Should Use What

Otter.ai Is the Right Choice If:

• You're a team that reviews meetings asynchronously. Product teams, customer success teams, and research teams that need to go back through call recordings will find Otter's searchable archive and collaboration features valuable.
• CRM integration is non-negotiable. Otter's Salesforce and HubSpot integrations are mature. If your sales ops workflow depends on automatic call logging, Otter slots in cleanly.
• Budget is the primary constraint. At $17/month with annual billing, Otter is meaningfully cheaper for individuals and small teams.
• You need 40+ language transcription. Otter supports more languages for transcription than Cluely's 12+.
• Your team is comfortable with a bot in calls. If the visible recording participant isn't a friction point in your meeting culture, Otter's model works fine.

Cluely Is the Right Choice If:

• You need to perform better in live conversations. Sales calls, job interviews, client presentations, negotiations — any scenario where what you say in the moment determines the outcome.
• You can't have a bot in your call. Sensitive conversations, executive meetings, or any context where a visible AI recorder changes the dynamic.
• Pre-call preparation matters. Cluely's People Search pulls intelligence on attendees before the call starts — LinkedIn context, past conversation history, relevant background.
• You want AI that reads your screen. Cluely's OCR analyzes what's on your display in real time, which means it can help with slide presentations, shared documents, or any visual content during a call.
• You're in sales. The real-time objection handling and response suggestions are built for revenue teams. The $2.5M enterprise deal Cluely signed was specifically for sales use cases, according to their Series A coverage.

How Real-Time AI Works Under the Hood

Cluely's technical architecture is fundamentally different from a transcription tool. While Otter processes audio linearly (record → transcribe → analyze → output), Cluely runs a parallel processing pipeline:

1. Audio capture feeds into Deepgram and AssemblyAI for speech-to-text
2. Screen capture feeds into OCR for visual context extraction
3. Both streams merge and route to GPT-4-class models (OpenAI + Anthropic)
4. The model generates contextual suggestions based on conversation flow, screen content, uploaded documents, and conversation history
5. The overlay renders suggestions in ~300ms — fast enough to feel synchronous with natural conversation

This multi-modal approach (audio + visual + context) is what makes real-time assistance possible. Otter only processes the audio channel. Cluely processes audio, visual, and document context simultaneously.

The Honest Trade-Offs

Cluely is younger (founded 2025), less proven at enterprise scale, and carries the baggage of its "cheating tool" origin story — the founders were suspended from Columbia University for building Interview Coder, the predecessor product. A mid-2025 data breach affecting 83,000+ users didn't help the trust narrative, though the company has since achieved SOC 2 Type II, ISO 27001, and HIPAA compliance.

Otter has been around since 2016, has deep enterprise penetration, and has never positioned itself controversially. It's a safer corporate purchase. Its transcription quality is battle-tested across millions of hours of audio.

The honest assessment: Otter is more mature, more stable, and more widely trusted. Cluely is more capable in the specific dimension that matters most — helping you in the moment. The risk calculus depends on whether you value institutional stability or cutting-edge capability.

FAQ

Is Cluely really undetectable in meetings?

The $75/month Undetectable tier makes the Cluely overlay invisible to screen-sharing APIs on Zoom, Teams, Meet, Webex, RingCentral, and Slack. Other meeting participants cannot see the overlay when you share your screen. Cluely also has a dedicated undetectability test page where you can verify this before subscribing. The Pro tier ($20/month) does not include this feature.

Can I use Cluely and Otter.ai together?

Yes. They operate independently — Otter joins as a bot and records; Cluely runs as a local overlay and coaches. There's no technical conflict. Some users run Cluely for real-time help and Otter for post-meeting archival, though this doubles your subscription cost.

Does Otter.ai offer real-time assistance?

Otter provides live transcription during meetings, so you can see what's being said in real time. But it does not offer real-time suggestions, answers, or coaching. It transcribes — it doesn't advise. The AI-generated insights (summaries, action items, key topics) are produced after the meeting concludes.

Is Cluely safe for enterprise use?

Cluely holds SOC 2 Type I and Type II, ISO 27001, GDPR, CCPA, and HIPAA certifications. Enterprise plans include a full Data Processing Agreement, a commitment that enterprise data is not used for model training, and white-glove onboarding. The company's 2025 data breach is a legitimate concern for security-conscious buyers — but the compliance certifications earned since then suggest the security posture has materially improved.

Which is better for sales teams?

Cluely, and it's not close. Real-time objection handling, competitive intelligence surfaced mid-call, and invisible operation (no bot alerting your prospect that AI is in the room) are all features specifically designed for sales workflows. Otter is better for post-call CRM logging and team review. The ideal sales stack arguably includes both, but if you're choosing one, Cluely's real-time coaching directly impacts close rates in a way that post-meeting transcription cannot.

The Verdict

Otter.ai is an excellent transcription tool. It records, transcribes, and organizes meetings better than most alternatives, and its team collaboration features are genuinely useful. If your primary need is "I want a searchable record of every meeting," Otter delivers.

But the question the market is now asking isn't "how do I remember what happened?" It's "how do I perform better while it's happening?"

That's Cluely's bet. Real-time over post-meeting. Invisible over visible. Coaching over transcription. The $20.3M in funding from a16z and Abstract Ventures suggests the smart money agrees with the direction.

The tools aren't interchangeable. They solve different problems at different points in the meeting lifecycle. But if you're forced to choose — and most individual users are — the more defensible investment is in the tool that makes you better in the room, not the one that reminds you what the room looked like afterward.
