Synthesia

London-based Synthesia offers a studio for turning scripts into videos narrated by AI avatars, with a strong focus on corporate training, onboarding, and internal communications. The company reports more than 50,000 teams as customers.

Videos can be produced in more than 140 languages and voices, and existing footage can be dubbed in the original speaker’s voice and accent, with optional lip-sync and a custom glossary for brand terms. One-click translation localizes finished Synthesia videos. Creators can add quizzes, clickable calls to action, and branching paths, while Interactive Avatars and Sessions run real-time roleplay and survey conversations. Personal avatars of real employees are available from the Starter plan, and the Avatar Builder creates custom presenters. For learning teams, videos embed in courses and can be exported as SCORM packages that update when the source video changes. Security credentials include SOC 2 Type II, ISO 27001, ISO 27701, and ISO 42001, along with GDPR compliance, EU data residency, and SSO and SCIM for enterprise accounts.

Large organizations with compliance requirements and L&D departments producing training at scale are the natural customers. Smaller buyers should note that several features learning teams rely on, including SCORM export, brand kits, and SSO, sit in the custom-priced Enterprise tier. The Starter plan adds only about 12 extra minutes of video per month, which is enough for occasional use but tight for regular production.
