Choosing an AI webinar platform is harder than it looks. Some tools price by attendee tier, some by attendee credits, and some only by quote. AI features also vary. They range from summaries and captions to chat bots and content repurposing.

This article compares 10 tools: Zoom Webinars, GoTo Webinar, Livestorm, Demio, BigMarker, Goldcast, Zuddl, Airmeet, WebinarGeek and eWebinar.

After the tool-by-tool sections, you will find picks by goal and tips for choosing without regrets. Prices and features can change, so check the official website for the latest pricing and features before you decide.

What Are AI Webinar Platforms? What They Do and What to Know Before Choosing

AI webinar platforms are tools for running live, automated, or on-demand webinars, with AI features added around the broadcast. The AI usually handles work before and after the session, such as summaries, captions, and content creation. It can also help during the session, for example by answering chat questions.

Based on the features in the tools compared here, typical uses include the following:

• AI summaries and chapters: turning a recording into a summary or chapters so viewers can jump to the parts they need (Zoom Webinars, WebinarGeek).
• Live captions and transcripts: showing captions during a session and keeping a searchable transcript afterward (GoTo Webinar, Livestorm).
• Content repurposing: creating clips, blog posts, social posts, and emails from a recording (Goldcast, Zuddl, Airmeet).
• Automated chat answers: answering attendee questions when the host is away (Demio, eWebinar).
• Engagement analysis and lead scoring: analyzing results and identifying sales opportunities (BigMarker, WebinarGeek).

Before choosing, check what the free plan or trial covers. Several tools state no free plan, and some offer only a trial. For example, eWebinar and WebinarGeek list a 14-day free trial, while GoTo Webinar lists a trial without a stated period. Goldcast has a free plan, but only for Content Lab, not for its event products. Check the official website for the latest pricing and features.

Japanese support varies widely. Some tools translate only attendee-facing screens, while the organizer dashboard stays in English. Others do not state Japanese support at all, so confirm which parts you need in Japanese.

Also compare scale and pricing model. Livestorm charges by attendee credits, Demio by attendee tier and host, and Zoom Webinars by monthly or annual plan. Zuddl and BigMarker are aimed at larger event programs, and their pricing is quote-based or starts at a high annual level. Most of these tools run in a web browser, while Zoom Webinars and GoTo Webinar also offer desktop and mobile apps.

Features, Pricing, and Best For: 10 Tools

1. Zoom Webinars

Zoom Webinars is a license for hosting one-way broadcast webinars from the Zoom Workplace app. It suits companies that already use Zoom for internal meetings and want to extend the same app to customer seminars and product announcements. According to the official website, it supports up to 100,000 attendees and up to 1,000 video panelists.

• Strengths: It runs in the same app as Zoom Meetings, so the barrier to adoption for attendees is low. AI webinar summaries, AI-generated chapters and AI captions in more than 20 languages are included in the plans, with no additional fee stated.
• Strengths: The official website, pricing page and product page can be read in Japanese. Attendees can join from Web, Windows, macOS, Linux, iOS and Android, and live transcription and interpretation support more than 35 languages.
• Strengths: The pricing page clearly shows both monthly and annual prices.
• Things to note: Prices for attendee tiers above 500 and for usage-based attendee options are not published, so you need to contact sales. Prices are shown in USD even on the Japanese pages, so exchange rates affect the cost.
• Things to note: AI generation for event pages and AI video snippets is for Webinars Plus and above, and for Sessions and Events. The entry-level Webinars plan cannot use them. The product page now presents an AI assistant called "ZoomMate," while support pages still use the name "AI Companion." Zoom has not published a statement linking the two names, so check both when you look into AI features.

Pricing: As of November 7, 2026, Webinars costs $89/month billed monthly or $66.67/month billed annually. Webinars Plus costs $99/month ($82.50/month billed annually). Events costs $149/month ($124.17/month billed annually). All three plans are for up to 500 attendees. A free plan is not stated. Attendee tiers of 501 or more, up to 100,000 attendees, are not publicly priced, so contact sales.

Best for: Companies that already use Zoom and want to run webinars in the same app. It also suits teams that want Japanese-language website and pricing pages, as long as they accept USD pricing.

2. GoTo Webinar

GoTo Webinar is a webinar broadcasting tool from GoTo. It bundles registration pages, automatic reminders and follow-up emails, polls and live Q&A, and reports and analytics into one license. The official pricing page has three plans: Reach, Elevate and Complete.

• Strengths: Basic management features such as registration, reminders, polls, Q&A and reports are included from the entry-level Reach plan. Elevate and above include AI summaries and transcripts, which makes recordings easier to use.
• Strengths: Complete offers 3,000 attendees and unlimited live stream viewers, according to the official pricing page.
• Strengths: According to the official help, live captions support 9 languages including Japanese. Attendees can join from desktop apps on Windows, macOS, Linux and Chrome OS, from iOS and Android apps, and from browsers such as Chrome and Edge.
• Things to note: The prices on the pricing page are rendered by script, so we could not confirm them on November 7, 2026. Check the official page before signing up. The product page FAQ lists "Reach, Elevate, Unlimited," which does not match "Complete" on the pricing page.
• Things to note: No Japanese version of the official website was found, and Japanese display in the admin screen could not be confirmed. AI summaries, transcripts and cloud recording are not included in Reach.

Pricing: A free trial is available, but the period is not stated. Reach is billed annually and includes 1 organizer seat and 500 attendees. Elevate is billed annually and includes 1,000 attendees plus AI summaries and transcripts. We could not retrieve the Reach and Elevate amounts, so check the official pricing page. Complete requires contacting sales and includes 3,000 attendees, unlimited live stream viewers and a custom number of organizer seats. Currencies include USD, AUD, CAD, EUR, GBP, MXN, BRL and INR.

How to Choose Without Regrets

Match the pricing model to how you run events

The tools charge in different ways. Livestorm uses attendee credits in annual packs, Demio prices by attendee tier and host, and eWebinar prices by the number of active eWebinars and monthly registrants. Estimate your attendance and event frequency first, then see which model fits.

Check what the free plan or trial covers

Few tools state a free plan. WebinarGeek and eWebinar list a 14-day free trial, and GoTo Webinar and Airmeet list a free trial. Goldcast offers a free Content Lab plan, which covers repurposing recordings, not its event products. BigMarker requires contacting sales even for a trial or PoC.

Confirm which screens support Japanese

Japanese support is usually partial. Zoom Webinars offers Japanese on its website, pricing page, and product page. Livestorm, Demio, Zuddl, and eWebinar translate attendee-facing screens, but their organizer dashboards or admin screens are in English. BigMarker, Goldcast, and Airmeet do not explicitly state Japanese support, so confirm this before you sign.

Size the tool to your team

Smaller teams may prefer published prices, such as Demio's Starter at $45/month billed annually or WebinarGeek's Premium from €59/month. Zuddl starts from $10,000/year for 2 organizers, and BigMarker's plans are quote-based with annual contracts. Those two fit larger event programs better than a team running a few webinars.

Decide whether you need live, automated, or both

eWebinar focuses on automated webinars, and its official website does not mention live streaming. If you also need live sessions, you would use a separate tool alongside it. Tools such as Zoom Webinars, GoTo Webinar, and WebinarGeek cover live broadcasting, so check platform needs too. Only Zoom Webinars and GoTo Webinar list desktop and mobile apps. Confirm the final decision with a qualified professional where contracts or data handling are involved.
