Best AI Webinar Tools 2026
Webinars remain one of the highest-ROI demand generation channels in B2B — but the platforms have diverged sharply. Modern tools like Demio and Livestorm prioritize clean attendee UX and marketing automation, while legacy players like GoTo Webinar coast on brand recognition. Enterprise platforms like ON24 offer deep analytics and AI-driven engagement scoring, and BigMarker stands alone for teams running virtual summits and multi-track events. We evaluated six leading webinar platforms on engagement features, automation depth, analytics quality, and total cost of ownership.
Three things webinar platforms must do
Engagement without friction
Polls, Q&A, chat, and calls-to-action that keep attendees active throughout — delivered without requiring downloads or account creation that kill registration conversion rates.
Automated nurture sequences
Pre-event reminders, post-event follow-ups, and evergreen replay delivery that work without manual intervention — turning a one-time event into a continuous lead nurturing asset.
CRM-connected attendance data
Individual-level attendance and engagement data synced to your CRM automatically, so sales can prioritize follow-up based on watch time, poll responses, and content interactions.
