Synthesia
AI VideoEnterprise AI video studio with avatars, voice cloning and 160+ language localization
An enterprise-grade AI video studio with the strongest localization stack in the category, built to mass produce training and communications content rather than to send a different video to each prospect.
Best for
Learning, communications and marketing teams at larger companies that need on-brand video produced and localized at volume without a studio.
Not great for
A sales team that needs one video per prospect delivered into an inbox or a LinkedIn message, since Synthesia produces the video but does not send it or book from it.

Synthesia, in plain terms
Synthesia is an AI video generation platform used mainly by large organizations to produce training, onboarding, internal communications and marketing video without cameras or studios. Users write or paste a script, pick from 240+ stock AI avatars or create a personal avatar cloned from their own face and voice, and the platform renders a presenter-led video. Localization is its strongest suit: 1,000+ AI voices across 160+ languages, AI dubbing with lip sync, and one-click translation into 80+ languages with a multilingual player that plays in the viewer's language. Around the editor sit the things enterprise buyers ask for, including brand kits, live collaboration, version control, analytics on views and watch time, interactive quizzes, CTAs and branching, SCORM export, public, password protected and SSO video pages, and a large LMS integration surface covering Docebo, Moodle, SAP Litmos, Articulate 360, TalentLMS and others. The company claims SOC 2 Type II, ISO 42001 and GDPR compliance, over 1 million users and more than 50,000 companies. Pricing is credit based, starting with a free plan at 1,200 credits per month, with Starter and Creator capped at roughly 10 and 30 minutes of video per month before volume moves to custom Enterprise pricing. The product is built for content that many people watch rather than for one-to-one sales prospecting: there is no prospect list, no sending layer and no booking step, and per-recipient personalization is an API exercise using template variables.

Pros
- 240+ stock AI avatars and 1,000+ voices across 160+ languages claimed
- Personal avatars that clone face and voice, plus AI dubbing with lip sync and 1-click translation into 80+ languages
- SOC 2 Type II, ISO 42001 and GDPR compliance claimed, which clears most enterprise procurement
- Deep learning-platform integration surface with Docebo, Moodle, SAP Litmos, Articulate 360 and TalentLMS, plus SCORM export
- Analytics on views, watch time, engagement and clicks, with interactive quizzes, CTAs and branching
- Free plan with 1,200 credits per month and no credit card required
Cons
- Credit and minute caps bite quickly: about 10 minutes of video per month on Starter and 30 on Creator before volume moves to quoted Enterprise pricing
- Built for training, communications and marketing content rather than per-lead prospecting, with no prospect list, no sending layer and no booking step
- Per-recipient personalization requires building against the API with template variables rather than a campaign interface
- Personal avatar creation requires explicit consent and a screening process before the avatar can be used
- An October 2023 Freedom House report documented state-linked misuse of Synthesia avatars in propaganda videos; the company says it improved misuse detection in February 2024 and added user screening and content moderation in April 2024

Synthesia sells credit-based plans. Their published pricing in August 2026 lists a free Basic tier with 1,200 credits per month, Starter at $29 per month or $18 per month billed yearly, and Creator at $89 per month or $64 per month billed yearly. Enterprise is quoted. Credits translate into video minutes: roughly 10 minutes per month on Basic and Starter and 30 minutes per month on Creator. Check their pricing page for current figures.
Yes. The Basic plan is free with no credit card required and includes 1,200 credits per month, up to 10 minutes of video, 25 AI-generated video assets and access to their language and voice library. The Synthesia logo stays on free videos.
Yes. Personal avatars clone both face and voice, with 3 on Starter, 5 on Creator and unlimited on Enterprise. Creation requires explicit consent, and Synthesia states that new users and content are screened before an avatar can be used, a policy it tightened after documented misuse of its avatars in 2023.
Not on its own. Synthesia generates videos and can render many of them from a template using variables through its API, with a callback ID to tie each render back to a recipient. It does not carry a prospect list, an email or LinkedIn sending layer, or a booking step, so delivery has to be handled by another tool.
Its published use cases centre on training, compliance training, onboarding, internal communications, product explainers, customer service content, sales enablement material and marketing video. The integration list is weighted heavily toward learning platforms such as Docebo, Moodle, SAP Litmos, Articulate 360 and TalentLMS, plus SCORM export.
One of these tools is ours.
Weezly is in this directory too: LinkedIn outreach with AI clone videos, a 300M+ leads database and booking, from $59 per month. See if it earns a spot in your stack.
