DeepBrain AI Overview

DeepBrain AI is an AI video generation platform with four major integrated products:
- AI Human: Create 2D and 3D multilingual digital humans that align with your business. Also provides customized AI chatbots.
- AI Studios: A very easy-to-use text-to-video editor. 100+ AI avatars, 100+ voices, 80+ languages and 500+ video creation templates.
- AI Interview (beta): 10 AI interviewers as your HR recruiters. Generate automatic interview questions. AI resume screening.
- AI Avatars: Built-in 100+ AI avatars with varied personalities, 80+ languages, and accents.
Basically, their software lets you type in a script, and it will generate a video with a realistic animated person talking. It’s wild!
The avatars they have are insane—they look like actual real people, but AI creates them.
You can choose from different unique models, or you can even make a custom avatar of someone specific. (I’m talking photo-realistic celebs, politicians, anyone.
The avatars have real-time facial expressions and lip-syncing and everything.
And get this: they can speak any language! So you can have your AI video in English, Spanish, Chinese, Korean, whatever.
You don’t need a studio, cameras, actors. Just type up a script, put it into DeepBrain’s video maker, and boom—you’ve got a professional-looking video in no time.
And it saves a ton of money compared to hiring a whole production team and crew.
They’ve got a bunch of templates too, for marketing videos, tutorials, training videos, all sorts of stuff.
And their online editor is super user-friendly, anyone can figure it out. Drag and drop titles, and images, and adjust the text and audio, it’s intuitive.
Oh, and the best part is you can have conversations with the AI avatars! Ask them questions, and they’ll respond to you in real time like a person.

- Huge library of diverse avatar options
- Ability to make custom-branded avatars

- Smoother avatar gestures and body movement
- Customization options for avatar facial expressions

Soul Machines Overview

Soul Machines makes these digital avatars called “Digital People.” They use artificial intelligence and computer animation to make the avatars mimic real human behavior and conversation.
The Digital People can be used for customer service, marketing, entertainment, education—all kinds of stuff.
Companies can customize a Digital Person to represent their brand and interact with customers.
I watched some videos of their Digital People in action and it’s nuts how realistic they look and sound.
The facial expressions and body language are spot on. And they can hold a conversation and answer questions like a real person.
The best part is the avatars are animated automatically based on the AI, so they come to life on their own. Soul Machines doesn’t have to keep manually animating them.
Soul Machines has partnered with big brands like Mercedes-Benz to create digital versions of their vehicles that can talk to potential buyers.
And they’re working with celebrities like Will.i.am from the Black Eyed Peas to make digital avatars of them too.
Seems like this technology could be huge in the future as AI gets even more advanced.
We might be chatting with digital avatars all the time instead of real humans! But in a good way, to make things more convenient and efficient.
What We Like About Soul Machines
- Digital People look and behave very realistically with expressive faces and natural conversations
- Customizable avatars that can represent brands, celebrities, etc
- Efficient method of creating digital content that animates itself
- Useful applications for customer service, marketing, entertainment, education
Where We Wish Soul Machines Did Better
- More diversity in the appearance and voices of Digital People
- A wider variety of clothing/accessory options for customizing avatars
- Expand use cases into more domains
- Add capabilities like analyzing sentiment, providing recommendations
- Enable Digital People to reference external data sources when conversing
With that out of the way, let’s look at the best features of both tools.
DeepBrain AI Features
1. AI Video Generator and Editor
You don’t need to be an expert or a rocket scientist to create incredible videos with DeepBrain AI.
The user interface makes it easy for anyone to create amazing videos with human-like AI avatars.
This is the same for their AI Studios as it is for the video editor.
Talking about avatars, you get 70+ of them with a text-to-speech ability in over 100 languages.
And it’s not just the TTS option that you get, DeepBrain has different starting options to avoid blank slate like:
Importing PowerPoint:

Creating a video with ChatGPT:

URL to AI video:

And plenty more!
The best part is, you don’t need any fancy video editing skills or equipment.
All you have to do is type in a script, and this will turn it into a full-blown video with realistic human avatars.
The video quality is insane too. We’re talking crisp 4K resolution here.
You can even get custom avatars made that look just how you want. Like, literally design your own spokesperson!
Along with the video creator, the editor is user-friendly too. Because all you have to do is input your text/script, it can not get any easier.

You don’t need any editing experience and with voice-over options of over 80, it only takes around 5 minutes to create a video.
All it takes is a simple 3-step process to complete the whole process of exporting a video.

You can also choose to enable/disable automatic subtitles for your video.
2. Multi-Language Text-to-Speech
As briefly discussed earlier, DeepBrain AI supports text-to-speech in multiple languages.
Besides English, here are all the languages your avatars can speak in:

And it’s so easy to preview any voice. All you need to do is input the text and press play.
You can even preview all the voices in this sample page:

Besides the pre-built voices, you can also create custom voices for specific business purposes.
DeepBrain AI also provides inside tools to adjust avatar voice parameters like pitch, speed, and volume.
3. Prebuilt Video Templates
DeepBrain has over 100 templates to pick from, covering stuff for business, sales, presentations, education, and more.

The templates are really high quality and professionally designed.
So even if you’re not a video editing expert, you can make something that looks professional using the templates.
All you have to do is plug in your text, images, logos, etc. into the template and the AI does the rest!
Oh, and they just added some templates that use ChatGPT narration too. So the AI can generate the voice-over along with the video!
4. Custom Avatars
You read that right. DeepBrain AI also enables you to create custom avatars (or as I like to say it: digital doppelgänger) for your desired needs.

First, you head over to their studio/video editor and record yourself reading some lines.
Don’t worry, they give you the scripts!
The DeepBrain folks want to capture your voice, facial expressions, mannerisms—everything that makes you, you.
Then their AI tech works its magic. It analyzes all that video and audio of you to create a custom synthetic version of your voice.
And using the latest in deep learning, it generates an avatar with your actual face, voice, and movements.
In about a month or so, your very own AI avatar is ready to go! This digital clone can be used for all kinds of things:
- Virtual assistants
- Presentations
- Customer service reps
- And more!
The whole process is pretty easy and hands-off for you.
5. Conversational AI Human Chatbots

DeepBrain’s Conversational AI Humans are super cool virtual humans who can have natural conversations with real people.
They use cutting-edge artificial intelligence to understand what you’re saying and respond like a real human would.
And they are designed to be hyperrealistic. I’m talking detailed facial features, subtle expressions, different accents, the entire shebang.
When you chat with them, it feels like you’re talking to an actual person instead of a robot.
The best part is, they can chat with you about anything, anytime.
And get this: the AI Humans can be customized for different industries and purposes.
You can have an AI banker, an AI teacher, or an AI salesperson.
Soul Machines Features
1. Digital DNA Studio

The Creator Tools (aka digital DNA studio) from Soul Machines lets you make your own digital people that are animated and talk just like real humans.
You start by choosing a face and body, kind of like making a character in a video game.

There are different options for hair, clothes, gestures, and more so you can really personalize your digital human.

Now here’s the mind-blowing part: you can give your digital person its own intelligent personality!
Soul Machines integrates natural language processing and AI so you can have natural conversations with your creation.
You can choose different voices too. It’s wild how human-like these digital peeps are!
My favorite part is you can deploy your digital human anywhere – websites, apps, social media – to talk to customers or be a virtual assistant.
With Creator Tools, anyone can make next-level digital humans and put them to work. Super easy too since it’s drag-and-drop.
2. Digital Celebrities

Soul Machines has this super cool thing called Celebrity Partners where they team up with famous personalities to make digital versions of them.
They use their tech to recreate the celeb’s face, voice, mannerisms, etc.
Then the digital celeb can chat and hang with fans, promote stuff, and do all kinds of things their human counterpart can’t get to.
Digital celebs can be programmed to rap in different languages, give advice, tell stories, and plenty more.
So far they’ve made digital versions of dudes like basketball star Carmelo Anthony and golf legend Jack Nicklaus.

Soul Machines custom-builds each one with the celeb to get their vibe and essence right.
If you are a celebrity or a business looking to partner with a celebrity, having a digital twin could let celebs connect with way more fans worldwide without being burned out.
Brands can partner with the digital celebs too for promotions and events. Seems like a total win-win.
3. Customization
When it comes to creating your digital human, Soul Machines’s DDNA Studio offers countless customization options to create exactly what you want.
Once you head over to creating a new project, you will see this dashboard:

Here, you will be able to create and fully customize your digital human before deploying it to your desired location.

The interface is divided into three parts:
- The left sidebar shows the table of contents for all the customization options.
- The middle pane is the display of those options.
- And the right side displays all the changes you make along with the TTS preview capability and deployment options.
In a nutshell, you can make a truly unique digital human for your business/personal needs by modifying the following:
Avatar selection

Avatar’s behavior

Conversation and skills

Language and voice

This is not it. You can even change the primary user interface of the deployed avatar page. That includes, but is not limited to, the camera angle and background color.
Besides the fact that the digital human creation and deployment process is slower than expected, the output is pretty good.
And the flexibility to personalize your digital humans to your likability makes it even more useful and powerful.
Pricing
DeepBrain AI offers a free trial that allows users to experience one AI interview production for free.

The Starter plan starts at $30 per month with a total of 10 minutes per video. The Pro plan starts at $225 per month with 20 minutes per video.
Soul Machines offers a 30-day free trial. They offer three paid plan options:

- Studio BASIC ($39 per month)
- Studio PLUS ($199 per month)
- Studio PRO ($399 per month)
Before You Go…
Now before you go rushing off to try them out, here are my closing thoughts:
For most business video purposes, I’d give the edge to DeepBrain AI. The avatar and template variety plus the easy web editor really open up the possibilities for fast, quality video content.
However, if you want next-level realism and customizability, Soul Machines creates incredibly life-like digital humans. Useful for specialized applications.
Consider your budget. DeepBrain AI starts more affordable, while Soul Machines scales up higher for enterprise needs.
Try before you buy! Both offer free trials so take them for a spin.
