🤔 What Is Synthesia?

Synthesia is an AI video platform that helps businesses create professional videos without cameras or actors. It lets you generate videos from text using AI avatars and voices.

The tool aims to make video content creation scalable and affordable. It’s designed for marketing, training, and customer service video needs.

⚙️ How We Tested Synthesia

We tested Synthesia’s Starter plan at $18/month (billed yearly) for two weeks. Our tasks included creating a short marketing video for a new product launch, generating an onboarding video for new hires, and localizing a training module into Spanish.

✨ Key Features (What Actually Stood Out)

Synthesia stands out for its extensive library of AI avatars and languages, making it easy to produce diverse content. It’s a strong option for founders looking to produce video content at scale without traditional filming. For more tools that help with content, check our content creation tools category.

• AI Avatar Generator — We could choose from over 240 stock AI avatars, which offered good diversity. Customizing outfits and environments for specific scenes worked well.
• Instant Voiceovers — The platform converted our scripts into voiceovers using 160+ languages. The voices sounded natural, though some emotional nuances required careful script phrasing.
• AI Video Editor — We used pre-designed templates to quickly convert text into video drafts. The editor made it straightforward to add text overlays and royalty-free media.
• Video Translator — This feature automatically translated our videos into multiple languages. It saved time when preparing content for international audiences.
• Team Collaboration — We could share projects and get feedback in real-time within shared workspaces. This helped coordinate video production among team members.

💰 Synthesia Pricing — Is It Worth It?

Synthesia’s pricing is structured annually, which is a common approach for business-focused SaaS tools. Founders should note the yearly billing commitment, even for the monthly-advertised prices. Usage caps on video minutes are the main differentiator between plans. For other tools that help with marketing efforts, explore our marketing tools section.

Plan	Price	Best For	Watch Out For
Starter	$18/month (billed yearly)	Individuals or small teams starting with AI video	Limited to 120 video minutes/year
Creator	$64/month (billed yearly)	Growing businesses needing more video volume	Higher minute allowance, but still a yearly commitment
Enterprise	Custom pricing	Large organizations with high volume and custom needs	Requires direct contact for a quote

Our pick: Starter — It provides enough video minutes for initial testing and smaller projects without committing to a higher tier.

🧪 What We Found During Testing

Creating our marketing video was surprisingly fast. We typed in the script, picked an avatar, and had a draft in minutes. The AI handled basic lip-syncing and gestures well.

For the onboarding video, we appreciated the ability to quickly duplicate and modify scenes. However, getting the avatar to convey specific emotions, like enthusiasm for a new product, sometimes felt a bit stiff. We had to experiment with different voice styles and avatar choices to get closer to our desired tone.

The translation feature for the training module worked as advertised. It automatically generated a new voiceover in Spanish, which saved significant time compared to manual dubbing. The overall quality was good for informational content.

A founder in our community who runs a B2B SaaS company told us the AI avatars felt a bit too ‘perfect’ for their brand’s authentic, casual tone.

⚠️ Limitations We Found

• Avatar Expressiveness — While avatars are realistic, achieving subtle human emotions or specific non-verbal cues can be challenging. As of our testing, they can still appear somewhat robotic in certain contexts.
• Annual Billing Only — The Starter and Creator plans are billed annually, even though prices are shown monthly. This requires a larger upfront commitment for founders.
• Usage Caps — Each plan has a strict limit on video minutes per year. Going over these limits means upgrading to a more expensive plan, which can be a sudden cost increase.
