Synthesia turns a script into a presenter-led video — an AI avatar reads your words on camera, in whichever of its 140+ languages you need, with no camera, studio, or actor involved. It's become the default pick for corporate training, product walkthroughs, and onboarding videos at companies that need a lot of video and not a lot of production time, and it's one of the tools that comes up most often when people ask us what's actually worth paying for in the directory.

What it actually does
You write or paste a script, pick an avatar and a template, and Synthesia generates a video of that avatar speaking your words with reasonably natural lip-sync and pacing. Under the hood it's doing three separate jobs well: text-to-speech that doesn't sound robotic, an avatar model that holds up at normal viewing sizes, and a timeline editor simple enough that someone outside the video team can use it without training. You can also feed it a doc or a prompt and have it draft a rough script and scene structure for you, which is less about quality and more about not staring at a blank page.
The real unlock isn't any single video — it's updating one. A policy changes, a product gets a new feature, a course needs a correction: you edit the script, not the footage. That's the difference between a training video that gets quietly out of date because nobody wants to re-shoot it, and one that actually stays current.
Pricing, in plain terms
Synthesia runs on a credit system rather than a flat "X videos per month" cap, which takes a minute to get used to but is fairly transparent once you do:
- Free — a small monthly allowance (about 10 minutes of video), 9 stock avatars, watermarked exports. Fine for testing the waters, not for anything you'll actually publish.
- Starter (~$29/mo billed monthly) — removes the watermark, adds downloads and 125+ avatars. This is the realistic floor for a small business that wants to use the output anywhere public.
- Pro (~$89/mo) — the plan most teams land on. Adds personal avatars (your own face, cloned, with consent), branded video pages, and a meaningfully larger credit allowance.
- Enterprise — custom pricing, unlimited minutes, SSO, and the compliance features a larger org's IT team will ask about.
Credits convert roughly to one minute of finished video per 100 credits, with dubbing and lip-sync costing a bit more. Treat these numbers as a starting point — Synthesia adjusts tiers and credit costs periodically, so check their current pricing page before you commit to a plan.
Where it's genuinely good
The avatar quality is the best reason to use this over a cheaper alternative — at normal video sizes (not full-screen, not zoomed in on the face), it clears the bar of "doesn't look obviously fake" that a lot of competitors still don't. The translation and dubbing is the other standout: turning one English training video into 20 language versions without re-recording anything is a genuinely different capability than most teams had access to two years ago.
It's also just fast. A five-minute script-to-video turnaround that used to require booking a presenter, a room, and an editor now takes about as long as writing the script.
Where it falls short
The avatars are good, not invisible — if your audience is primed to look for AI video, they'll usually clock it within the first ten seconds. It's also not the tool for anything that needs genuine personality or improvisation; a scripted explainer is its lane, a casual vlog is not. And the credit system means cost scales with how much video you actually make, which is fairer than a flat cap but makes budgeting a heavier-use team's spend slightly less predictable month to month.
Who should use it (and who shouldn't)
If you're producing training content, internal comms, or product explainers on a recurring basis — especially across more than one language — Synthesia earns its subscription. If you need one video a year, the free tier or a human freelancer is the better call. And if your brand depends on video feeling personal and unscripted, this is the wrong tool regardless of budget.
FAQ
Does Synthesia have a free plan?
Yes. The free tier includes a small monthly video allowance and access to 9 stock avatars, but exports carry a watermark — it's meant for testing the tool, not publishing finished videos.
How many languages does Synthesia support?
Synthesia supports AI dubbing and translation into 140+ languages on its higher tiers, including lip-sync adjustment so the avatar's mouth movements roughly match the translated audio.
Can I use my own face as an avatar?
Yes, on the Pro plan and above you can create a personal avatar cloned from your own video and voice, with your consent built into the setup process.
