Cons
- −The free Basic plan is tightly capped, limiting you to 3 polls and 1 quiz per slido, 100 participants, and no Q&A moderation or custom branding.
- −Features many buyers consider essential, namely question moderation and custom branding, are locked behind the Professional plan at roughly 75 dollars per month, a steep jump from the 17.50 dollar entry Engage tier.
- −Paid plans are billed annually rather than truly month to month, which is awkward for teams that only run occasional or one-off events.
- −Reviewers report weak PowerPoint integration for Mac users and narrower visual customization and branding options than competitors like Mentimeter.
