What is Slido

Slido is a lightweight audience interaction platform that helps hosts collect questions, run polls, and measure sentiment in real time. It focuses on live Q&A, multiple poll formats, quizzes, and basic analytics so presenters can make sessions interactive with minimal technical overhead.

Compared with Mentimeter and Poll Everywhere, Slido emphasizes seamless event integration and fast setup for hosts. Unlike some quiz-first platforms such as Kahoot!, Slido is optimized for professional meetings and conferences where anonymous questions, moderation, and quick audience feedback matter more than game-style competition.

Slido performs particularly well for internal all-hands, webinars, and conference sessions where you want a simple join flow, moderated Q&A, and a variety of poll types. Its ease of use and low friction for participants make it suitable for remote and hybrid teams, corporate events, and classroom settings.

How Slido Works

Participants join an event using a short event code or a direct link, with no account creation or downloads required. Hosts create polls and Q&A sessions in the web admin, activate them live, and share results instantly in the meeting or embed them in slides.

During a session attendees can submit questions, vote on other questions to surface the most popular ones, respond to polls, and take quizzes. Organizers moderate incoming items, pin or hide questions, and export results after the event for follow-up or reporting.

A typical workflow is: create an event in Slido, add polls and Q&A slots, start the session, invite attendees via link or code, moderate incoming questions in real time, and share live results with the audience inside the meeting platform or presentation.

Slido features

Slido centers on live interaction tools and easy setup. Core capabilities include live Q&A with moderation, several poll types, quizzes, quick surveys, live results display, basic analytics, and integrations with presentation and meeting platforms. The product highlights quick attendee join flows without logins and offers a free Basic tier alongside paid upgrades.

The platform includes several powerful capabilities:

Live Q&A

Hosts can collect audience questions in real time, allow voting on questions to prioritize what matters most, and moderate items before they appear to attendees. This helps keep sessions focused and surfaces the most popular topics quickly.

Multiple poll types

Slido supports several poll formats including multiple choice, word cloud, rating, and open text, allowing presenters to capture different types of feedback and sentiment during a session. Different formats help maintain engagement across formats and session lengths.

Quizzes and icebreakers

Quizzes provide interactive, timed questions that work well for training sessions and classroom use. They add a gamified element while still providing scoring and instant feedback to participants.

Live results and charts

Poll results update in real time and can be shown as charts, word clouds, or lists to the audience. Live visualizations help speakers respond immediately to audience input and keep presentations dynamic.

Moderation tools

Organizers can review incoming questions, hide or pin items, and filter out inappropriate content before it reaches attendees. Moderation controls are essential for larger events and public sessions.

Analytics and exports

After an event, hosts can download participant responses, poll results, and Q&A logs for reporting or follow-up. Basic analytics provide a quick view of engagement metrics and question trends.

Integrations and embeds

Slido integrates with presentation and meeting platforms so polls and Q&A can appear inside slides or conferencing apps. This reduces context switching and keeps engagement inside the session flow.

Easy join flow

Attendees join using a code or link without needing to create accounts or install software, which lowers participation friction in mixed-technical audiences. This simplicity is a core usability advantage for live events.

With these features Slido makes it straightforward to run interactive sessions, get instant feedback, and keep audiences engaged without complex setup or steep learning curves.
