AI co-host vs notetaker: what's the difference (and which one do you actually need)

"AI meeting tools" covers at least three kinds of product, and they solve different problems. Buying the wrong one is expensive in a way that doesn't show up until you have already connected it to your CRM.

This guide covers the three kinds (post-meeting notetakers, audience-input platforms and real-time co-hosts), when each one is the right choice, and how to tell them apart before you sign anything.

The three kinds at a glance

A quick test: anything that joins the meeting, records audio and sends a summary is a notetaker, however the website describes it.

Post-meeting notetakers

These tools join your call, record audio, and produce a transcript and summary after the meeting ends, which they send to your inbox or CRM. They are mature and useful for anyone who runs a lot of calls. You get a searchable transcript, a summary you can paste and action items you can route. Some flag moments such as pricing or a competitor's name by scanning the transcript afterwards.

They don't tell you anything while the call is happening. The recap arrives after the decision was already shaped. If your problem is "I don't remember what was said," a notetaker fixes it. If your problem is "the call went sideways and I didn't notice," it won't.

Audience-input platforms

These tools turn the audience into structured input. Participants scan a QR code or visit a short URL, then vote in a poll, add a question to a moderated Q&A board or contribute to a word cloud. The host runs the activity and the audience takes part on purpose.

They suit a 200-person all-hands where every question should be seen and ranked, a keynote that opens with a word cloud, or a class that checks understanding every ten minutes: any setting where the audience is meant to take part visibly and the host has time to run it.

They don't read the room passively. If people don't want to take part, or doing so breaks the flow of the conversation, an input platform is the wrong tool. A one-to-one sales demo is no place to put up a QR code.

Real-time co-hosts

These tools follow the call as it happens and give the host a private view of what is going on: questions stacking up, people going quiet, the same topic coming up from different people. The product is awareness during the call, not a recording to replay.

They fit calls where you need to know what people are thinking but can't stop to ask: workshops, training, demos, onboarding, research interviews. They don't replace a notetaker entirely; where a co-host produces a recap, it is a by-product.

Picking by role

In sales, you are sharing your screen, the prospect is mostly muted, and the question that decides the deal may be one line in chat over 45 minutes. Asking a prospect to scan a QR code mid-demo only adds friction.

In onboarding, a confused rollout is a renewal at risk months later. The early signs are silence after the technical slide, repeat questions about the same admin step, and a sponsor who stopped engaging partway through.

In research, the same pain point from three users in a week is a roadmap input; the same pain point buried in three transcripts tends to stay buried.

In recruiting, bias creeps in when interviewers' notes drift apart, and many candidates dislike being recorded. A notetaker is appropriate only with explicit consent and a clear retention policy.

For trainers and facilitators, the job is to know who is still following while you teach. A co-host that also runs polls and quizzes covers most of what an input platform would.

What about Gong and Chorus?

Gong and Chorus are revenue intelligence platforms. They sit on top of recorded sales calls and find patterns across a whole team's call history. They are closer to a notetaker than a co-host, with an analytics layer aimed at the sales manager rather than the rep. A co-host helps the rep in the moment and Gong or Chorus helps the manager review afterwards, so they work alongside each other.

A quick decision guide

• Need to remember what was said and produce a summary? A notetaker (Otter, Fireflies, Read.ai).
• Need the audience to take part with polls, Q&A boards or word clouds? An audience-input platform (Slido, Mentimeter).
• Need to know what the room is doing while you can't watch it? A co-host (Claryoo).
• Need all three? Run them together; they don't conflict on the same call.

The mistake to avoid is picking a notetaker for a co-host problem because both say "AI." By the time you find the recap lands an hour after the deal slipped, you have paid the per-seat fee and wired up the integrations.

What Claryoo is

Claryoo is an AI co-host for live sessions. On Zoom, Google Meet or Microsoft Teams it joins the call as a participant, and people answer polls and quizzes by typing a letter in the meeting chat, with no link, code or QR code. In a room, people scan a QR code and answer on their phones. While you present, you privately see who is engaged, who has gone quiet and which question has waited longest, with every question from chat and voice on one board. When the session ends you get what was decided, follow-ups by name and the results.

Plans are billed by session hours, not seats. Start free: 2 session hours a month and 14 days of Pro, no card.
