SynthesiaReview

Overview

Synthesia makes videos with AI avatars instead of cameras. You write a script, pick an avatar and a voice, and Synthesia produces the video. It's built for teams that make a lot of training, onboarding or explainer content.

The feature list goes well past avatars. There's screen recording, a video assistant that turns decks and PDFs into videos, translation, dubbing and a player that switches to the viewer's language. If you publish in many languages, that's the big draw.

Pricing runs on credits. Every plan includes 10 minutes of video a month, and paid plans add credits on top. Plan your volume before you pick a tier. A typical finished minute uses about 100 credits, so the math is simple once you know your output. Credits you buy separately last 12 months, which helps if your workload comes in bursts.

Key Features

• Express-2 Avatars. They wave, point and clap based on your script.
• Personal Avatars. An avatar that looks and sounds like you and speaks more than 30 languages.
• AI Voices. Hundreds of natural-sounding voices.
• Voice Cloning. Captures your voice and pairs it with your Personal Avatar.
• AI Screen Recorder. Transcribes your voiceover, removes pauses and lets you fix mistakes.
• AI Video Assistant. Turns decks, PDFs and websites into videos, so the slides you already have can become a training video.
• 1-Click Translation. Translates a video into more than 80 languages.
• AI Dubbing. Keeps the speaker's natural voice, with lip sync.

Pricing

Synthesia offers Basic, Starter, Pro and Enterprise. Basic is free: 10 minutes of video, 3 survey responses and 500 credits a month, with a watermark. Starter adds 1,250 credits a month. Pro starts at 6,000 credits a month, and you can choose a higher credit level. The page says you can save up to 4 months by paying yearly. The pricing table on this page shows current prices.

Pros

• Avatar video without a camera crew. Express-2 Avatars even gesture on cue.
• Strong for multilingual work, with translation into more than 80 languages and dubbing.
• Screen recordings get cleaned up for you.
• The free plan is real: 10 minutes of video every month.
• Pro includes 5 Personal Avatars.

Cons

• Credits and minutes reset each billing period. Unused allowance doesn't roll over.
• If you hit your limit, video creation pauses until renewal, unless you buy more credits.
• Free videos carry a Synthesia watermark.
• Dubbing and surveys also eat credits. Dubbing with lip-sync costs twice as much as without.
• Unlimited video minutes are only on Enterprise.

Best For

• Training and enablement teams that want avatar videos instead of filmed presenters.
• Localization teams that need translation, dubbing and a multilingual player in one tool.
• Teams turning decks, PDFs, websites or screen recordings into videos.
• Buyers who can estimate their monthly video minutes before they commit.
• Small teams testing avatar video on the free Basic plan before they pay.

Verdict

Synthesia is a strong pick for avatar-led training and multilingual video. The translation and dubbing tools are the reason to choose it over a plain video editor.

The catch is usage. Credits reset every period and creation stops at the limit. Work out how many minutes you'll make, then pick Starter or a Pro credit level that covers it with room to spare. Not sure yet? Start on Basic and see how far 10 free minutes go.
