Slido review

Slido is audience-engagement software for meetings, events, and training. Hosts use it to run live polls, collect questions, launch quizzes, build word clouds, and send surveys before, during, or after a session. Participants can ask questions anonymously and vote for questions they want answered.

Participants can join without creating a login or downloading software. After a session, hosts can review engagement and export questions or voting results. That makes Slido a way to add audience input to a presentation or meeting, rather than a replacement for the presentation itself.

The product’s appeal is straightforward: one tool covers several common ways to get a room involved. The practical question is whether its audience caps and annual-only paid plans fit how often your team runs sessions.

Slido combines several useful event interactions in one product: live polls, anonymous Q&A with question voting, quizzes, word clouds, and surveys. Hosts do not have to limit participation to one format, and participants can join without a login or download. For occasional meetings and training, that keeps the basic setup relatively simple.

The plan ladder also spells out what you get as attendance grows. Basic is free for one user and allows up to 100 participants and three polls per Slido. Engage is listed at $17.50 per month as an annual billing equivalent, with one member, up to 200 participants, unlimited polls and quizzes, surveys, and data exports. Professional raises the cap to 1,000 participants and adds question moderation, branding, advanced privacy options, and organization analytics.

For event teams, Q&A voting can help surface questions participants care about, while exports give hosts a way to retain questions and voting results. One Reddit commenter says Slido’s PowerPoint plug-in works; that is an individual report, not a guarantee of a smooth production workflow.

The main buying constraint is annual billing. The pricing information we found lists monthly equivalents, but Slido does not accept monthly payments. Engage’s $17.50 rate therefore is not a month-to-month option. The free Basic plan is also limited: one user, 100 participants per Slido, and three polls.

Audience caps make the upgrade path important. Engage tops out at 200 participants; Professional is listed at $75 per month equivalent for up to 1,000 participants and includes two members. Enterprise is $200 per month equivalent, includes three members, and caps a Slido at 5,000 participants. The large-enterprise tier supports up to 20,000 participants and 10 or more members, but its price is not published and billing is custom.

That means teams needing a larger audience, more seats, or moderation and branding may face a substantial jump from the free tier. One Reddit thread also describes a production user’s screen-scraping workflow as frustrating, though another commenter says the PowerPoint plug-in works. Treat that as a workflow concern to check against your setup, not a settled product-wide verdict.

Slido has a free Basic plan, but paid plans are billed annually; the listed monthly prices are equivalents, not monthly payment options, according to the pricing information checked November 6, 2026. Basic costs $0 and allows one user, 100 participants per Slido, three polls, and basic Q&A.

Engage starts at $17.50 per month equivalent, billed annually. It includes one member, up to 200 participants, unlimited polls and quizzes, surveys, and data exports. Professional jumps to $75 per month equivalent—a $57.50 increase—for two members and up to 1,000 participants, plus moderation, branding, privacy options, and organization analytics. Enterprise is $200 per month equivalent, billed annually, for three members and up to 5,000 participants, with SSO and SCIM. Large-enterprise pricing is custom and not published; it lists 10+ members and up to 20,000 participants per Slido.

The pricing data lists no add-ons. The main cost gotcha is the annual commitment, alongside sharp price jumps between tiers.

The published product information does not describe migration tools, import options, or a step-by-step switching process, so the effort is not published. Participants can join without logins or downloads, which may reduce setup friction for a new event, but it does not establish how existing content transfers.

For leaving, the product description says hosts can export questions or voting results; Engage also lists surveys and data exports. The sources do not specify export formats, whether exports cover every plan, or what happens to data after cancellation. Confirm those details before moving a recurring event or training program. Slido’s participant caps also matter: a switch may be necessary if your audience exceeds your plan’s limit, from 100 on Basic to 5,000 on Enterprise; the large-enterprise tier lists up to 20,000.
