The webinar chat is often the only way your guests can talk to you. Even so, it tends to be an afterthought: it’s switched on, but nobody has decided who reads it, what is allowed there or what happens to the questions. This guide covers how to prepare and moderate the chat, how to answer questions well, and what to watch out for with automated webinars and data protection.
What the chat is for
A chat does several jobs at once. Guests ask questions, report technical problems and let you know whether they can keep up. For you, it is the best source of information about where your talk isn’t working. Questions that come up in every session almost always point to a gap in the content.
The chat also sets the mood. A chat where questions get answered feels welcoming. One where questions sit there unanswered feels deserted, however good the presentation is. That’s why it deserves as much attention as your slides.
Prepare the chat
Most chat problems can be solved in advance. Go through these points before your first session.
Decide on visibility. Can every guest see every message, or only your team? An open chat creates more conversation. A closed one protects people who don’t want to ask a question in front of everyone. Some platforms offer a middle ground where only approved messages appear.
Sort out names. Guests should be able to choose the name they post under. A first name or a nickname is enough. Email addresses have no place in the chat.
Pin a welcome message. A short note at the top of the chat explains who is answering and what guests can do if the sound or video drops out.
Prepare answers. From earlier sessions or emails, you know which questions will come up. Write short answers to the most common ones so whoever runs the chat doesn’t have to start from scratch each time.
Chat rules that fit in three lines
Nobody reads a page of etiquette. Three short sentences are enough, for example:
Welcome! Post your questions here and we’ll collect them for the Q&A. Please keep it friendly and don’t share personal details such as phone numbers or health information. We’ll remove posts promoting other offers.
Moderating during the webinar
Presenting and reading the chat at the same time is hard. If you do both alone, you either lose your thread or miss questions. Whenever you can, split the roles: one person presents, another looks after the chat.
The chat moderator has clear tasks:
- answer simple questions straight away, such as “You’ll get the slides by email after the session”,
- collect content questions and pass them to the presenter in batches,
- solve technical problems or point people to a help page,
- deal calmly with disruption.
Disruption mainly means spam, self-promotion and abuse. Remove those posts without comment, and block the person if it continues. Criticism is not disruption, though. If someone says you’re going too fast or a point doesn’t convince them, take it on board. A quick “Good point, we’ll pick that up in the Q&A” shows every guest that the chat is being read.
Answer questions about price, discounts or terms honestly and in full, even if the price comes later in the talk. “I’m not revealing that yet” sounds evasive. For how to handle price in the presentation itself, see when and how to mention the price in a webinar.
Answering questions well
Not every question needs an instant reply. A simple split works well.
| Type of question | When to answer | How |
|---|---|---|
| practical or technical | straight away | briefly in the chat |
| fits the point you’re on | shortly, at the right moment in the talk | out loud, reading the question first |
| general to the topic | in the Q&A | out loud, grouping similar questions |
| very personal or specific | after the webinar | by email or in a one-to-one call |
Read each question out before you answer it. Otherwise anyone watching later, or not following the chat, won’t understand your reply. Only say the guest’s name if they chose it themselves and there’s no reason not to.
If you don’t know something, say so. “I need to check that, I’ll send you the answer” beats a guess. Then make sure you follow up. To leave enough time for questions, build the Q&A into your running order, as described in the guide to writing a webinar script.
Many chat questions are really objections in disguise: “Does this work if I’m a complete beginner?” or “Do I have time for this?” Collect them across several sessions and work the most common ones into your talk. The guide on handling objections before they come up shows how.
The chat in an automated webinar
In an automated webinar, the presentation plays by itself. The chat still works, but you need to decide who answers in it. There are three common options.
- Collect questions and reply later. Guests post, and you reply by email after the session. It’s simple, but guests have to wait.
- A person or your team reads along. Someone is in the chat for some or all sessions and replies directly. It’s personal, but it takes time.
- An AI replies. An AI system answers questions based on the information you give it. It’s instant and works at any hour, but it needs careful setup and clear limits.
Whichever route you choose, guests should know about it. Anyone who gets a reply in a chat assumes, at first, that a person wrote it. If that isn’t the case, say so openly, ideally with a fixed note right next to the chat.
| Who replies | Possible note by the chat |
|---|---|
| you, later by email | “We’ll answer your questions by email after the session.” |
| your team | “Our team is reading along and will reply here.” |
| an AI | “Replies in this chat are written by an AI. For personal questions, please email us.” |
With AI replies there is also a legal duty. Article 50 of the EU’s Artificial Intelligence Act requires that people are told when they are interacting with an AI system, unless it is already obvious. These transparency rules apply from 2 August 2026. If you add the note now, you won’t need to retrofit anything later, and you’re being straight with your guests in the meantime.
An AI chat also needs limits. It should only answer from your information and, when it can’t answer, point people to an email address instead of making something up. It shouldn’t give personal advice on health, legal or financial matters. Read what it writes regularly during the first few weeks.
One thing has no place in any chat: pre-written messages that pretend to come from guests. Inserted comments such as “Wow, this is exactly what I needed!” deceive real viewers and can count as misleading advertising under EU consumer law. An empty chat at the start is more honest than a faked crowd. The comparison of live vs automated webinars explains where a recording’s limits lie compared with a genuine live session.
Data protection in the chat
People sometimes share more in a chat than they should. A few rules protect your guests and you, especially under the GDPR.
- Show as little as possible. First names or chosen display names at most, and no email addresses or other registration data.
- Warn against sensitive details. The note in your chat rules helps. If someone still posts a phone number or health details, hide the message from others and reply privately.
- Set a retention period. You need chat logs for follow-up, and not much longer. Decide when you’ll delete them and say so in your privacy notice.
- Don’t repurpose posts. Chat messages with names don’t belong in adverts or social media screenshots without consent.
- Name your processors. If a platform or AI service processes the messages, mention it in your privacy notice. You will usually need a data processing agreement with that provider.
Checklist for your webinar chat
- Visibility and display names are set up.
- A welcome message with three rules is pinned.
- Someone is responsible for the chat, or it’s clear when questions will be answered.
- Answers to common questions are ready.
- Guests can see who is replying, with a clear note if it’s an AI.
- There are no inserted fake comments.
- You have decided how long chat logs are kept.
Frequently asked questions
Should the chat be visible to all guests?
It depends on the webinar. An open chat encourages conversation and shows people that others have similar questions. A chat only your team can read works better if guests might ask personal questions or you want to avoid disruption.
How do I deal with trolls in a webinar chat?
Delete spam, self-promotion and abuse without discussion, and block repeat offenders. Fair criticism isn’t trolling and deserves a reply.
Do I have to say that an AI is answering in the chat?
From 2 August 2026, the EU AI Act requires that people are told when they are interacting with an AI system, unless it’s obvious. A clear note right next to the chat is the simplest way to do it, and it’s fair to your guests today as well.
What do I do with questions I don’t get to?
Collect them and answer them by email after the session, sending each reply to the guest who asked. Work the most common ones into your next presentation.
Final thoughts
A good webinar chat doesn’t happen by itself. It needs someone in charge or a clear rule about who answers, a few visible ground rules and careful handling of what guests write. Then the little box at the side of the screen becomes a real place for conversation.
