Using the Questions feature, attendees can use their devices or computers to send their questions to Slido and easily upvote the best ones. It's a simple way to crowdsource the most popular topics at meetings or events and see what people are genuinely interested in the most.
Your participants can ask an unlimited number of questions.
Participants can do this anonymously, but you do have the option to set up the event to require names. More information about this is in our Participant Privacy page in community.
In this article:
In order to start crowdsourcing questions, you need to create a Slido event first.
Ask your audience to join your event
Once you created an event, ask your audience to join it. The most common way to do this is to go to slido.com and enter the #eventcode of your event. Make sure the event dates you set up match the actual date as your participants can only use the event code during those dates. Alternatively, you can share the event link with them.
Following the event link, your participants can ask questions right away and they’re not limited by any timeframe.
Have the audience submit questions
Once your audience have joined the event, they can start submitting their questions. They can submit questions anonymously or with their name and they can upvote questions submitted by others.
Questions are sorted by their popularity, so the most popular ones appear on top. To modify the default settings, follow the Change the order of audience Q&A article.
Manage audience questions
There are three main things you can do with questions as an admin:
- Highlight the question that’s being answered so that it gets more attention both on the Present and Participant modes
- Mark the question as answered once you don’t want to display it anymore. You can then view those questions in the Archive folder
- Change the order of questions and filter for starred questions
With some of our paid plans, you can also moderate questions, i.e. review them before they go live.

Topics for Q&A
Our topics feature allows your participants to navigate and filter questions in a more structured way during a Q&A session. Topics are created automatically if there are at least 3 questions that the system identifies as the same topic and will group together in Slido Q&A. These are visible in participant mode only. This is how it will look for participants:

For the topics to show, the questions must be live for participants to see them, archived questions will not show.
How it works:
-
For Topics to automate, questions need to be live (visible in present mode, not archived)
-
Questions need to be in English
-
At least 3 questions need to be asked on the same topic for the topics to automate and be visible to participants
- Participants see the topics if:
- There are at least 20 questions and at least 1 topic, Or;
- At least 3 topics, regardless of the number of questions
- At the moment, Question topics are only visible in Participant mode
-
We estimate Q&A Topics using our own machine learning model. During this process, the data doesn’t leave our infrastructure and is not exposed to any third parties.
