Our verdict on Slido
Slido is an audience response platform for meetings, training sessions, webinars, presentations and events. Hosts can run live polls, surveys, quizzes and Q&A sessions, while participants respond or submit questions from their devices without downloads or logins. Anonymous questions, audience voting and real-time displays support two-way participation during live sessions. With a free plan and web, Windows, macOS and Chrome extension access, Slido suits presenters, trainers, event organizers and teams that need structured audience input.
Its strongest fit is the presentation and conferencing ecosystem. Slido integrates with PowerPoint, Google Slides, Webex, Microsoft Teams and Zoom, and it can be embedded in websites and event apps. That gives organizers several ways to bring polls, questions and results into an existing presentation or event workflow. Analytics and data exports add a useful follow-up layer for reviewing audience responses after a session. The published category specification lists an audience limit of 200, so organizers should align the product with the expected size of each event.
Slido uses a freemium model, making it suitable for evaluating core polling, Q&A and quiz workflows before committing to a paid tier. The main product scope is synchronous audience interaction: live responses, questions, voting, quizzes and displayed results. Its non-open-source model and listed audience limit may matter to organizations seeking self-hosted deployment or larger-scale participation. Choose Slido for presentations, meetings and events where familiar presentation or video-conferencing integrations are central. Consider another option when open-source deployment or an audience beyond 200 is a primary requirement.
