Slido: cost, fit and limits
Slido is an audience interaction platform made by sli.do s. r. o. of Slovakia, owned by Cisco Systems International B.V., offering live polls, quizzes and Q&A with add-ins for PowerPoint, Webex, Google Slides, Microsoft Teams and Zoom.
What to know first
Slido advertises a forever-free Basic plan and a paid option at EUR 15 per month, without naming that plan on the homepage. Its pricing tabs (one-time, annual, education, enterprise) did not render prices when read, and the privacy policy page could not be read. Slido AI is named for poll suggestions and refined wording, and five integrations are listed, so the product looks capable even though its terms stay unconfirmed.

Who Slido is best for
Meeting hosts on Teams, Webex or Zoom
Five integrations are named on the homepage, so a host in a corporate meeting tool can expect an add-in for the platform already in use.
Event organizers who run one-off events
The pricing navigation lists a One-time plan type next to annual plans, which suggests a pay-once option, though its terms did not render for this entry.
Universities on education pricing
An Education plans tab exists in the pricing navigation, but its contents were not readable, so a university should request those terms from Slido.
Slido plans and pricing
| Plan | Price | What it includes |
|---|---|---|
| Basic | Free (forever-free, per homepage) | Plan limits for participants, polls and quizzes are not stated on the pages opened, so the free tier cannot be sized from the vendor's site. |
| Paid plans (EUR 15 per month figure) | Not tied to a named plan: homepage says EUR 15 per month | The homepage says get more from Slido for only EUR 15 per month without naming the plan, billing period or limits that figure includes. |
| One-time and Annual plans | Not published on the pages opened | Plan names, prices and contents did not render in the pricing tabs when the page was read, so nothing further can be reported. |
| Education and Enterprise | Not published; Enterprise is a custom quote | The Education tab did not render, and Enterprise is linked from the pricing navigation as a custom plan with no contents shown. |

What Slido does
- Live quizzes
- Quizzes are listed as a product feature alongside polls and Q&A on the homepage. Which plan includes quizzes and what scoring options exist is not stated.
- Slido AI
- The homepage says Slido AI gives personalized poll suggestions and refined wording for questions, with no detail about limits, supported languages or which plan includes it, so test it before you rely on it.
- Named integrations
- PowerPoint, Webex, Google Slides, Microsoft Teams and Zoom are listed, plus an Embed Slido option and Combine Integrations for placing a session inside another page.
- Forever-free entry point
- A free Basic plan exists as the entry. Its caps were not visible on the pages read, so test it with a real session size before committing.
- Cisco ownership
- Slido is owned by Cisco Systems International B.V., which may matter for buyers who already buy Webex and want fewer vendors to assess, though no bundle or discount is described.
How Slido handles your data
The vendor's policy was not checked for this. The privacy policy URL returned an error, and the privacy notice PDF opened without readable text, so training on customer data, retention, hosting region and certifications are all unconfirmed. The only vendor document read was the terms page. A buyer should request the privacy notice and a data processing agreement directly from Slido before collecting personal data in a session, and ask specifically about AI features and any outside model providers.
Where Slido falls short in practice
- Plan details unreadable. The pricing tabs did not render plan names, prices or billing, so this entry cannot say what a paid Slido plan costs or includes beyond the EUR 15 homepage figure.
- Unanchored price. The EUR 15 per month figure is not tied to a named plan on the page, so it should be treated as a starting point to confirm, not a quote.
- Policy not verified. With the privacy policy unreadable, data handling is unknown. An organization with strict rules should not treat any silence here as acceptance of its terms.

Alternatives to Slido
Slido: common questions
Is Slido free?
The homepage describes a forever-free Basic plan. Its limits on participants, polls and quizzes are not stated on the pages read, so the size of events it can handle is unconfirmed. A paid option is advertised at EUR 15 per month without a named plan.
What does Slido cost per month?
The only figure on the pages read is EUR 15 per month on the homepage, with no plan name or billing period attached. The pricing tabs for one-time, annual, education and enterprise did not show prices, so a quote from Slido is needed.
Does Slido include AI?
The homepage names Slido AI, which gives personalized poll suggestions and refined wording for questions. Its scope, limits and plan access are not described on the pages read, and nothing was read about whether it trains on customer content, because the vendor's policy was not checked for this.
Which platforms does Slido work with?
The homepage lists PowerPoint, Webex, Google Slides, Microsoft Teams and Zoom, plus Embed Slido and Combine Integrations for placing a session inside another page. Which plans include which integration is not stated on the pages read, so a team that depends on one meeting tool should confirm support for its plan before it buys.
Where does Slido store data?
The vendor's policy was not checked for this. The privacy policy URL returned an error and the PDF notice had no readable text. Slido is made by sli.do s. r. o. of Slovakia and owned by Cisco Systems International B.V., but hosting regions, retention and training terms must be requested from the vendor in writing.
