Synthesia

Synthesia's site doesn't tell a founder story. There's no origin anecdote, no garage, no 'we got frustrated filming training videos.' What it does show is who the company has chosen to build for, and that tells you nearly as much. The navigation is organized around Learning & Development, HR, Sales Enablement, Compliance Training and SOP videos. It claims trust from "90% of the Fortune 100" and over 2,000,000 users. It also links to dedicated Responsible AI and AI Research pages. This is a company that decided early its customer is the corporate training department, not the TikTok creator, and the product reflects that choice everywhere.

The core is still AI avatar video. You write a script, or hand the AI Video Assistant a prompt, link, file or PowerPoint, and it produces a narrated video with a presenter in 140+ languages. The newest model, Syren, is billed as "our most advanced AI video model yet." You can create a personal avatar from a single photo, put stock avatars in branded outfits and backgrounds, or build 3D, comic, anime and claymation characters. Existing videos can be translated into 130+ languages with voice cloning and lip-sync. The enterprise focus shows up in the extras: quizzes, branching scenarios and calls to action inside videos, plus easy export into an LMS, which is exactly what the featured L&D reviewer praises.

The more interesting bet is Sessions. These are live, interactive avatars you can talk to: practice a cold call with "Marcus, Head of Sales," handle manager feedback with "Laura," or run conversational surveys at scale. Add an API for programmatic video creation, dubbing and real-time interactive avatars, plus MCP documentation, and Synthesia is clearly trying to be the video layer for corporate training rather than just a talking-head generator. If that's your world, it's a strong fit. If you want edgy creative video, you'll feel the corporate gravity.
