Synthesia
AI video platform for avatar-led training, sales, and explainer videos.

AI avatar video platform focused on workplace training, with doc-to-video and quizzes.

Overview
Colossyan creates presenter-led videos from text using AI avatars and synthetic voices, with a focus on learning and development. Users paste a script or upload a PDF, PowerPoint, or document and the tool drafts scenes, picks an avatar, and generates narration in over 70 languages. Interactive elements such as branching scenarios and quizzes can be added, and finished videos export as MP4 or SCORM packages for learning management systems. Small businesses use it for onboarding modules, compliance refreshers, product training for staff, and customer how-to videos without filming. It integrates with LMS platforms, Google Drive, and Microsoft Teams, and offers an API. Business adds custom avatars, voices, and team collaboration. The avatar style is corporate and polished rather than casual, so it suits internal and B2B content better than consumer social posts, and the Starter plan caps output at roughly 15 minutes per month.
