Synthesia lets you create professional videos by typing a script. No camera. No presenter. No editing software. An AI avatar reads your script in any of 120+ languages, and the result looks surprisingly professional.
We used Synthesia for 60 days across 12 real client video projects — product demos, onboarding videos, training materials, and marketing content. Here’s an honest assessment of what it can and can’t do.
How Synthesia Works
The workflow is simple: write your script, choose an AI avatar, choose a template, add your slides or visuals, and click generate. The video is ready in minutes.
The avatars are pre-built AI representations of real people who have licensed their likeness to Synthesia. There are 230+ avatars available — different genders, ethnicities, ages, and presentation styles. You can also create a custom avatar from a video of yourself (available on higher plans).
Video Quality
The honest assessment: Synthesia videos look professional but not quite human. The avatars move naturally when speaking, maintain appropriate eye contact, and use natural gestures. But close observers will notice the slight uncanny valley quality that distinguishes AI avatars from real presenters.
For the use cases where Synthesia shines — internal training, product walkthroughs, onboarding sequences — this quality is entirely sufficient. Nobody watching a software tutorial cares whether the presenter is AI or human. They care whether the information is clear and useful.
For customer-facing marketing videos where authenticity and trust are paramount, Synthesia is less ideal. Real presenters build more personal connection.
Key Features
120+ languages: Synthesia supports 120+ languages with native-speaker quality pronunciation. Genuinely impressive for businesses with international customers — one script, multiple language versions, no voiceover recording required.
Screen recording integration: Record your screen, add voiceover narration from an avatar, and produce a polished software tutorial without showing your face or recording your voice. Extremely useful for SaaS product demos.
Template library: 60+ professional templates covering common business video formats. Using a template cuts production time significantly — you’re filling in content, not designing layouts.
Pricing
- Free: 3 videos/month, limited avatars — good for testing
- Starter: $29/month — 10 videos/month, all avatars, 1 custom avatar
- Creator: $89/month — 30 videos/month, priority rendering, brand kit
- Enterprise: Custom — unlimited, custom avatars, SSO, API access
The Starter plan at $29/month is sufficient for most small businesses producing 2-3 videos per week. The free plan generates 3 videos per month — enough to evaluate whether the quality meets your needs before committing.
Affiliate Program
Synthesia pays 25% recurring commission on referred customers. On a $89/month Creator plan, that’s $22.25/month per referral — significant for affiliates with audiences of business owners or marketers.
Our Verdict
Score: 8.7/10
Synthesia is the best tool available for small businesses that need professional video content but lack the budget or skills for traditional video production. The quality is sufficient for most business video use cases — training, onboarding, product demos, and internal communication. The 120-language support is a genuine differentiator for businesses with international audiences.
