AI Avatars & Customization
DeepBrain leans toward natural, human-like avatars with smooth facial movements and clean vocal delivery. Their avatars are particularly well-suited for business presentations, training videos, and explainer content. If you’re creating videos that require a calm, direct, and conversational tone—like onboarding tutorials or sales enablement—DeepBrain feels more “corporate polished.”
It offers over 100 avatars, most of which look like real people in business attire. While customization options are somewhat limited in the lower-tier plans, enterprise users can create fully custom avatars of themselves or team members.
Great for: Talking head-style videos, internal communications
Synthesia
Synthesia currently leads the market in avatar variety and diversity, offering more than 140 avatars in multiple ethnicities, clothing styles, and professions. Many users love the ability to choose avatars that feel aligned with their brand’s personality or global audience.
Where Synthesia really shines is in avatar gestures and expressions. They’ve added slight head tilts, eyebrow movements, and even occasional hand gestures—making their avatars feel more dynamic and engaging on camera.
Great for: eLearning, localization, marketing campaigns
Winner (Avatars): Synthesia, for broader diversity and realism.
Language Support & Voice Quality
In a global content market, multilingual support isn’t optional—it’s essential. So how do DeepBrain and Synthesia compare?
Language Support
- DeepBrain: Supports over 80 languages, with an expanding list of accents and voice tones. You can select from a variety of male and female voices with different regional nuances.
- Synthesia: Leads with 120+ languages, including regional dialects and voice tones that feel more localized. If you’re producing content for audiences in India, Europe, or Latin America, Synthesia gives you more flexibility.
Voice Quality
- DeepBrain’s voices sound more natural in English and Korean, as the company is based in Seoul and fine-tunes these languages heavily.
- Synthesia’s voices sound highly polished across a wider range of languages. The prosody (the rhythm and intonation) feels more human, especially in European languages like Spanish, German, and French.
Tip: Both platforms let you adjust speech speed and tone, but Synthesia offers slightly more fine-tuning options in the editor.
Winner (Language & Voice): Synthesia, especially if you need multi-language delivery at scale.
Ease of Use & User Experience
Let’s face it—no one wants to wrestle with a clunky interface. Thankfully, both DeepBrain and Synthesia offer user-friendly design, but they cater to different styles of users.
DeepBrain Studio
DeepBrain’s interface is streamlined and minimalistic, perfect for users who want to go from script to video in a few clicks. The drag-and-drop editor includes basic visual assets like text overlays, transitions, and background changes.
However, it lacks deeper editing tools—so if you need advanced scene composition or animation effects, you’ll need to export the video and edit it in another platform like Adobe Premiere or Final Cut.
Synthesia Studio
Synthesia’s UI feels a bit more feature-rich. You can add scene transitions, animate elements, insert background music, and even embed clickable links (great for eLearning). There’s also a timeline view for managing longer videos with multiple scenes.
It’s built for enterprise training and marketing teams, so if you’re making longer courses or want more built-in media, Synthesia gives you more control.
Note: Synthesia has a slight learning curve, but it pays off in flexibility.
Winner (Ease of Use): DeepBrain for speed and simplicity; Synthesia for power users.
Pricing: Which One Offers Better Value?
Here’s where things get interesting—and where your choice might come down to budget vs. video volume.
DeepBrain Pricing (as of 2025)
- Starter Plan: $30/month for 15 minutes of video
- Pro Plan: $225/month for 90 minutes
- Enterprise: Custom pricing, includes custom avatars and API access
You can also buy add-on video minutes without upgrading your entire plan, which is a nice bonus for small creators or one-off projects.
Synthesia Pricing (as of 2025)
- Personal Plan: $22.50/month (billed annually), includes 10 minutes/month
- Enterprise: Custom plans with unlimited seats, integrations, and API
Synthesia doesn’t offer flexible add-ons unless you’re on a business plan, which can be limiting for creators who just need a few extra minutes.
👀 Important: Neither platform offers unlimited video generation at any tier, so you’ll want to estimate your monthly volume accurately.
Winner (Pricing): DeepBrain for lower upfront cost and add-on flexibility
