Synthesia

What is Synthesia?

Synthesia is a web-based AI video platform that generates presenter-led videos from a typed script. Instead of filming a human presenter, users select one of 240+ pre-built AI avatars — or create a personal avatar from a short recording of themselves — and Synthesia renders a lip-synced video in whichever of 160+ languages is selected. The output is a downloadable MP4 or a shareable hosted link, produced in minutes rather than the hours or days a traditional shoot requires.

The platform handles the full production workflow in one place: script editing, avatar and voice selection, slide-style scene layout, screen recording, and basic brand customization via a Brand Kit. For teams distributing content globally, AI Dubbing can translate an existing video into 140+ languages without re-recording. An analytics dashboard tracks viewer engagement at the scene level, which is useful for identifying where audiences drop off in training or onboarding content.

The main architectural constraint is the credit-based output limit. Free accounts get 10 minutes of video per month; the Starter plan keeps the same 10-minute monthly ceiling (120 minutes spread across an annual plan). The Creator plan raises this to 30 minutes per month. Teams producing high volumes of video will hit these limits and need to plan for the Enterprise tier or budget overages accordingly.

Who is it for?

Synthesia is built primarily for teams that need to produce repeatable, structured video content — not cinematic or brand-campaign work. The platform’s LMS integrations, SCORM export, and analytics are designed for corporate learning and development departments. Its multilingual dubbing and avatar-based localization make it practical for HR and internal communications teams operating across multiple regions.

• L&D and HR teams producing onboarding, compliance, and training modules who need to update content regularly without re-booking presenters or studios
• Marketing and sales enablement teams creating product explainers or demo videos that need to exist in multiple languages for global markets
• IT and operations teams documenting internal processes or software walkthroughs using the AI screen recorder, where a polished but not cinematic output is sufficient
• Agencies and freelancers building white-label video production services for SMB clients who cannot afford traditional video production costs
