Synthesia
Turn a written script into a video narrated by an AI avatar
1/4Synthesia is a web-based AI video platform that turns a written script into a finished video narrated by an AI avatar, without a camera, studio or actors. It is aimed at learning and development, internal communications, sales enablement and marketing teams, who use it for training courses, product walkthroughs and customer-facing explainers. Finished videos can be translated into 80+ languages in one click, exported as SCORM for an LMS, or embedded and shared on a hosted page with view analytics. Synthesia integrates with Docebo, TalentLMS, Moodle, SAP Litmos, Articulate 360, PowerPoint, Slack, Microsoft Teams, Notion, HubSpot and Workday among others, and offers an API from the Creator plan upwards. The video editor is desktop-only; mobile browsers get a reduced experience.

What people are saying about Synthesia
50% neutral“one session with @synthesiaIO's AI roleplay coach was more useful than all of them”
“If you want an authoritative talking head narrating safety protocol while relevant diagrams pop up smoothly, this is the gold standard.”
“Even when teams use Loom,HeyGen, or Synthesia to create training content, the exported videos may still need quality enhancement or format conversion before being uploaded to an LMS or shared across different devices. What AI tools would you recommend for this stage of the workflow?”
“When you use something like synthesia or Heygen, how much effort / time does it usually take? Do they have templates that are easy to use?”
“For onboarding, HR updates, compliance, or repeatable internal modules, Synthesia and HeyGen make sense. This is where you want a clean talking-head style video without recording a person every time.”
“It's great for plain talking head content and less ideal for content where you need to interact with things suuch as unboxing videos or so.”
“Most of the AI video tools that are actually mature right now (Synthesia, HeyGen, etc.) are built around talking-head avatars because that's the easiest generation problem.”
“**Synthesia:** Synthesia is clearly built for structured training and educational content. Its current workflow supports AI presenters, script-to-video production, collaboration features and updates without reshooting. The whole experience is designed around professional, polished delivery.”
“I tried synthesia first. It was well made but wrong for me. It's built for explainer videos and that's not what i make. Heygen is where i've been since and the custom avatar there is fine.”
“For product explainers, feature announcements and structured software walkthroughs, I can see clearly why it works. The presenter is clean, professional and consistent across the whole video.”
“Probably the easiest one to get into for realistic-looking clips. The interface isn’t too confusing and the multi-shot stuff is useful when you need more than one isolated scene.”
“hey gen and synthesia both gate that behind paid tiers and the free credits run out fast.”
“AI Avatar - Synthesia”
“the avatar tools, Synthesia and Heygen being the obvious ones, are built around a presenter delivering information. the output is well lit, well framed, centered, and that framing is correct for an explainer and wrong for an ad, because the whole reason UGC works on a feed is that it looks like it wasn't produced. the ad-native tools go the other way.”
“Storyline (never rise per my manager) and Synthesia”
“**Synthesia:** This is the real deal if you need a spokesperson on screen. You pick an avatar from their library (there are a lot of them), paste your script, choose a language, and it renders a video of a photorealistic presenter delivering your content. Clean lip sync.”
