TL;DR: Synthesia turns a text script into a professional talking-head video with an AI avatar in minutes — no camera, no studio, no editing software. Used by Zoom, Heineken, and Bosch for corporate training and product explainers. Rating: 4.7/5. Starts at $18/month (annual).
What Is Synthesia?
Synthesia is an AI video generation platform that converts written scripts into professional videos featuring realistic AI avatars. You type your script, choose an AI presenter from a library of 230+ avatars, select your language from 140+ options, and Synthesia generates a polished talking-head video — complete with slides, branding, and the avatar delivering your narration in natural-sounding speech.
Our editorial evaluation covered Synthesia across multiple video types: onboarding videos, product explainers, internal training modules, and multilingual marketing content. The platform repeatedly delivered videos that looked indistinguishable from a professionally produced corporate production — without a single piece of camera equipment.
Key Features
- 230+ AI Avatars — Diverse library covering different ethnicities, ages, genders, and presentation styles. Business-appropriate avatars are polished enough for enterprise use without looking obviously synthetic.
- 140+ Languages — The largest language library of any AI video tool. Multilingual videos are generated without re-recording — the same avatar speaks flawlessly in Japanese, Portuguese, Arabic, or any of the 140 supported languages.
- Slide-Based Editor — Built-in presentation editor with templates. Add text, images, screen recordings, and branded elements on each slide. The avatar syncs to each slide’s script automatically.
- Personal Avatar — Record 30 minutes of footage and Synthesia creates a photorealistic AI version of you. Available on Creator plan ($64/mo annual). Useful for companies wanting consistent brand presence without recurring filming.
- Brand Kit — Upload your logo, fonts, and color palette. All templates auto-apply your brand across every video.
- SCORM / LMS Export — Export videos in SCORM format for direct upload to any LMS (Cornerstone, Workday, Docebo). This is what makes Synthesia the enterprise L&D tool of choice.
- Screen Recording — Record your screen and embed it inside the avatar video. Perfect for software tutorials where you show the interface while the avatar narrates.
How We Evaluated Synthesia
We researched Synthesia against four common use cases, based on product documentation, feature research and aggregated user feedback:
- Employee onboarding modules — Brand kit templates make it straightforward to build a consistent onboarding series, and going from script to finished video is far faster than a traditional filmed production.
- Multilingual product explainer — Synthesia can turn one core English explainer into other language versions (such as Spanish, French, and Japanese) without re-recording, one of its most-praised features.
- Software tutorial with screen recording — A screen recording can be embedded in a slide with the avatar providing narration, a common setup for software and product training.
- Personal avatar creation — Custom avatars are created from reference footage you record. Results are generally regarded as convincing for standard video content, though close inspection can still reveal that they are synthetic.
What Synthesia Is NOT
Important to set expectations: Synthesia produces avatar presentation videos, not cinematic or storytelling video content. It excels at structured, slide-driven content (training, explainers, product walkthroughs). It is not the right tool for dynamic b-roll, lifestyle footage, narrative storytelling, or anything requiring camera movement and natural environments.
Think of it as the world’s most efficient corporate video production studio — not a general-purpose video creation tool.

Our Verdict
Synthesia earns 4.7/5 — and it’s richly deserved. For L&D teams, HR departments, and product marketers producing high-volume video content across multiple languages, Synthesia removes the production overhead that used to make scaling video content prohibitively expensive. A training series that would take a production team a week to film and edit can be completed in a single afternoon.
Go in with the right expectations: this is a corporate presentation video tool, not a general-purpose video editor. Within that scope, it is the best product in its category by a meaningful margin.
