The 10 Best AI Tools for Webinars in 2027

How We Ranked These

We weighed five things. Live reliability came first — an AI feature is worthless if the stream drops, so platforms with proven uptime and large concurrent capacity scored higher. AI depth measured whether the artificial intelligence is genuinely useful: live transcription, automatic summaries, chapterized recordings, content repurposing, and conversational Q&A over the recording. Production workflow rewarded tools that shorten the post-event grind — clip generation, blog drafts, and follow-up emails built from the session. Analytics and engagement favored platforms that score attendee attention and intent rather than just counting heads. Finally, value compared what you actually pay against the capability, with bonus weight for usable free tiers.

We separated two categories that buyers often confuse: live broadcast platforms that happen to include AI (Zoom, ON24, Teams, Webex, Goldcast, BigMarker, Livestorm, Demio), and AI companions that bolt onto whatever you already run (Otter.ai, Opus Clip). Both belong on a 2027 shortlist because most teams pair a host platform with a dedicated repurposing or transcription tool.

1. Zoom Webinars + AI Companion 🏆 BEST OVERALL

Zoom Webinars is an add-on to Zoom Workplace that converts the familiar meeting interface into a one-to-many broadcast, with view-only attendees, Q&A, polls, and practice sessions. Capacity tiers scale from 500 attendees up to 10,000, and Zoom Events pushes far beyond that for conferences and summits. The reason it tops the list is the combination of broadcast muscle and AI that costs nothing extra.

Zoom AI Companion is included at no additional charge on paid Zoom plans, which is rare in this category. It generates a post-session meeting summary, produces Smart Recording with automatically detected chapters and highlights, and lets hosts query the recording afterward in plain language ("What questions did attendees ask about pricing?"). For producers, that erases the manual step of scrubbing a 60-minute replay to find the moments worth clipping or following up on.

It's best for teams that already live in Zoom and want one vendor for meetings, webinars, and AI. The trade-off: Zoom's marketing analytics are thinner than a dedicated demand-gen platform, so revenue teams often pair it with their CRM. For all-purpose product launches, training, and customer webinars, nothing else matches the price-to-capability ratio when the AI is bundled in.

2. ON24

ON24 is a webinar and digital-experience platform built for B2B marketing, anchored by ON24 Webcast Elite for live sessions. Where Zoom optimizes for the broadcast itself, ON24 optimizes for what happens after — capturing first-party engagement data on every click, poll, resource download, and minute watched, then feeding that into integrations with marketing automation.

Its AI layer, the Analytics and Content Engine (ACE), automatically generates derivative content from a single webinar: summaries, key takeaways, and even landing pages, so one live session becomes a small content library without manual rewriting. ON24 also produces an engagement score per attendee, helping teams prioritize follow-up by interest level rather than raw attendance.

ON24 is best for demand-generation and field marketing teams whose webinars feed a pipeline and who report to revenue on cost-per-influenced-opportunity. Pricing is enterprise and quote-based on annual contracts, so it's overkill for a team running an occasional internal town hall — but for a marketing org running dozens of gated webinars a quarter, the analytics depth justifies the spend.

3. Microsoft Teams + Copilot

Microsoft Teams runs three relevant formats: meetings, Teams webinars (up to 1,000 interactive attendees), and town halls for large one-to-many broadcasts reaching into the tens of thousands depending on license. For organizations already paying for Microsoft 365, it adds webinar capability with registration pages and reporting at little marginal cost.

The AI is Microsoft Copilot in Teams, which generates real-time and post-meeting summaries, surfaces action items, and answers questions about what was said during the session. With intelligent recap, attendees who join late get an AI-built timeline of topics and speakers. Copilot requires a separate license on top of Microsoft 365, which is the main asterisk on cost.

It's best for Microsoft-standardized enterprises that want webinars inside the same security, compliance, and identity perimeter as the rest of their stack. Production polish for high-glamour external launches lags purpose-built event tools, but for internal all-hands, training, and partner webinars, the single-vendor governance is the selling point.

4. Cisco Webex Webinars

Cisco Webex Webinars supports interactive sessions and a webcast view mode that scales to roughly 100,000 attendees, making it one of the highest-capacity options for genuinely large broadcasts. It carries Cisco's enterprise reliability and security pedigree, which matters for regulated industries and government.

The Webex AI Assistant delivers automatic transcription, real-time translation across many languages, meeting summaries, and message-drafting help. For global webinars with multilingual audiences, the live translation is a standout that several competitors handle less gracefully. Webex also offers noise removal and speaker-optimization audio AI that improves broadcast quality on the production side.

Webex Webinars is best for large, multilingual, security-conscious organizations — think global enterprises and public sector. The interface is more utilitarian than flashy event platforms, so marketing teams chasing a branded experience may find it plain, but for sheer scale plus translation, it earns its spot.

5. Goldcast

Goldcast is a B2B event and webinar platform whose differentiator is content repurposing. Its Content Lab uses AI to slice a recorded webinar into short, captioned video clips, draft blog posts and social copy, and pull quotable moments — directly attacking the bottleneck most teams hit, which is turning one live event into weeks of distributable content.

On the live side, Goldcast handles single webinars and multi-session virtual events with registration, branded stages, and engagement tools. The pitch to marketers is a closed loop: run the event, then let AI mine the recording for a content calendar instead of paying an agency or burning editor hours.

Goldcast is best for content-led marketing teams that treat every webinar as raw material for a quarter of derivative assets. It's an enterprise purchase, so smaller teams will find it pricey, but the Content Lab repurposing alone can replace a separate clipping subscription and part of a content role.

6. BigMarker

BigMarker is a fully browser-based webinar and virtual-event platform — no downloads for hosts or attendees — with a strong reputation for customization and automation. It supports live, automated, and on-demand "evergreen" webinars, plus large virtual summits with multiple tracks and exhibitor booths.

Its automation is the draw: simulated-live (automated) webinars replay a recording on a schedule while still capturing registrations, chat, and offers, so a single great session can run repeatedly as a lead engine. AI features assist with transcription, captions, and session highlights, and the platform's API and white-label options let teams embed webinars directly into their own sites.

BigMarker is best for marketers running funnels and evergreen webinars at scale, where the same on-demand session needs to convert visitors around the clock. The depth of configuration means a learning curve, but few platforms match its automation flexibility for always-on lead capture.

7. Livestorm 💎 BEST VALUE

Livestorm is a browser-based webinar and virtual-event platform known for a clean interface and a genuinely usable free plan — up to 30 attendees for sessions capped at 20 minutes — that lets teams test the full workflow before paying. Paid tiers scale registrants and session length, with higher plans reaching into the thousands of live attendees.

Because everything runs in the browser, setup friction is near zero, and Livestorm bundles registration pages, email reminders, polls, and analytics in one place. Its AI assists with automatic transcription and post-session summaries, plus engagement reporting that shows drop-off points and active participation. For teams that want the essentials without an enterprise contract, the capability-per-dollar is the best on this list — which is why it takes best value.

Livestorm is best for startups, SMBs, and lean marketing teams that run regular webinars but can't justify ON24 or Goldcast pricing. The ceiling is lower than enterprise platforms for massive branded summits, but for the volume most teams actually run, it covers the job at a fraction of the cost.

8. Demio

Demio is another no-download, browser-first webinar platform aimed at marketers, with a focus on conversion-oriented features like in-session offers, handouts, and call-to-action buttons that appear at timed moments. It supports live, automated, and hybrid (live-plus-recorded) sessions, with higher tiers reaching up to 3,000 attendees.

Demio leans into the registration-to-replay funnel: branded sign-up pages, automated reminder and follow-up emails, and detailed analytics on who watched, for how long, and what they clicked. AI features support transcription and session insights, and the interface is deliberately simple so non-technical hosts can run a polished event without a producer.

Demio is best for small and mid-market marketing teams prioritizing lead conversion over sheer scale. It sits close to Livestorm in positioning; the choice usually comes down to interface preference and which automation and offer tools fit your funnel.

9. Otter.ai

Otter.ai is not a broadcast platform — it's an AI meeting and webinar companion that joins your session to deliver live transcription, automatic summaries, and searchable notes. The Otter Meeting Agent generates an outline as the session runs and produces takeaways and action items the moment it ends, working alongside Zoom, Teams, and Webex rather than replacing them.

For webinar teams, the value is the searchable transcript and AI summary of every session, which becomes the source material for follow-up emails, blog drafts, and accessibility captions. Otter also lets you query past recordings conversationally, so finding the exact moment a speaker quoted a statistic takes seconds instead of a manual scrub.

Otter.ai is best for teams that want AI notes layered onto whatever platform they already use, especially when their host tool's native AI is weak or unlicensed. It won't broadcast to 100,000 people, but as a transcription-and-summary layer with a free tier and affordable paid plans, it's the most flexible add-on here.

10. Opus Clip

Opus Clip is an AI repurposing tool that turns a long webinar recording into short, vertical, captioned clips ready for social distribution. It analyzes the full video, identifies the most compelling moments, assigns a virality score to each clip, auto-reframes the speaker to keep faces centered, and burns in animated captions — collapsing hours of editing into minutes.

For webinar producers, this solves the last-mile problem: a 45-minute session is too long for anyone to share, but ten 30-second clips fuel weeks of LinkedIn, YouTube Shorts, and Reels posts. Opus Clip also supports keyword-based clip selection, so you can pull only the segments about a specific product or theme.

Opus Clip is best for content and social teams that want maximum reach from each webinar without an editor in the loop. It does nothing live — you bring the recording — but as a dedicated clip-generation engine, it's the cleanest way to extract distributable assets from any platform's exported video.

FAQ

Which AI webinar tool is best for a small team on a budget? Livestorm wins on value with a real free plan (30 attendees, 20-minute sessions) and affordable paid tiers, while Demio is a close alternative for conversion-focused funnels. Pair either with Otter.ai for AI notes if the native summaries fall short.

Do I need a separate AI tool, or is it built into the platform? Most live platforms now include some AI. Zoom AI Companion is bundled free on paid plans; Microsoft Copilot costs extra. For clip-making and content repurposing, a dedicated tool like Opus Clip or Goldcast Content Lab still does a better job than native features.

What's the best tool for very large audiences? Cisco Webex Webinars scales to roughly 100,000 attendees in webcast mode, and Zoom Events plus Microsoft Teams town halls also handle very large broadcasts. For tens of thousands of viewers, those three are the safest bets.

How does AI actually save time on webinars? It removes the post-event grind: automatic transcription, summaries, chapterized recordings, engagement scoring, and clip generation replace hours of manual editing, note-taking, and follow-up writing. The biggest payoff is repurposing one session into many assets.

Can these tools translate webinars for global audiences? Yes — Cisco Webex AI Assistant offers real-time translation across many languages, and several platforms provide AI captions and translated transcripts, making them suitable for multilingual and international webinars.

Which tool is best purely for turning recordings into social clips? Opus Clip is purpose-built for it, with virality scoring, auto-reframing, and animated captions. Goldcast Content Lab does similar work inside its event platform if you're already hosting there.

Bottom Line

For 2027, Zoom Webinars with AI Companion is the best overall pick because it pairs proven broadcast scale with free, bundled AI that genuinely cuts production work. Marketing teams chasing pipeline should choose ON24 for its content engine and engagement analytics; budget-conscious teams should start with Livestorm. Then add a specialist — Otter.ai for notes or Opus Clip for social clips — and you have a complete AI webinar stack that runs the live event and extracts weeks of content from it.
