The Best Synthesia Alternatives of 2024 [With Video Examples!]

synthesia alternatives

The world is moving fast, continuously driving us to find easy and faster ways to do things. From using supercomputers to now creating and editing videos with generative AI, things can only get better. 

With all the capabilities of a voice artist, video editor, and human-AI avatars, Synthesia.io makes it easy to create AI videos in record time, reducing the stress of traditional video creation. 

People who hate being on video will love how easy it is to use AI avatar generator software programs to create educational or training videos from just a PowerPoint, PDF, or an article!

As a filmmaker and video content creator myself, I’ve looked at and tried out many different AI video tools. Synthesia is a unique tool in that it’s got tons of digital avatars to choose from, and they look and sound pretty realistic (you’re not going to mistake their avatars for real people yet, but maybe one day…!).

However, there are some other tools that have different or alternative features, and that’s what we’re going to look at in this article.

Here’s a video I made using the Synthesia AI software. Take a look, and notice how their avatars look, move, and sound. You’ll be able to compare this video to other videos made with some of the other programs later in this article.

NOTE: This video was created by me using Synthesia. The images were created by me in Canva, and the script was written by me.

best Alternative Overall

1. HeyGen – Best Overall (Most Realistic Avatars)

Synthesia alternative: HeyGen AI video maker

Quick Take

HeyGen is my overall favorite AI avatar generator. Its avatars look WAY more realistic than any of their competitors (including Synthesia!). HeyGen is trusted by several top brands like Amazon and Salesforce, and it provides a fantastic alternative to being on camera for small teams, solopreneurs, and online influencers!  

Key Features

  • It’s got 100+ diverse and customizable human avatars, helping you personalize your videos and connect with your audience.
  • My favorite feature is their “instant avatar”, which lets you create a digital avatar version of yourself! Seriously, try it out for yourself – you’ll be amazed!
  • The software includes tons of stock images and video footage, and there’s even an AI image generator for when you can’t find what you are looking for in the stock images!
  • HeyGen has partnered with ElevenLabs, so its AI voices sound super-realistic (the best of any that I tried!).

What I Like Most About HeyGen

  • HeyGen is the only AI avatar program (so far) that is able to create an instant avatar of you! It’s so much fun to play around with, and it’s free to create!
  • HeyGen uses the AI voices from Elevenlabs, which has the most realistic-sounding voices! This software has the most realistic-sounding voices of any of the programs that I tried.
  • HeyGen’s user interface looks a lot like Canva’s, which made it very familiar to me.
  • It includes TONS of stock images and videos that you can use in your videos, making your videos super engaging and attention-grabbing for viewers.
  • HeyGen also includes an AI image generator right inside the software program – it’s so easy to use!
  • Love their free trial video – you can make a video of up to one minute for free, including your avatar of yourself!

What I Didn’t Like About HeyGen

  • The program has a bit of a learning curve. I checked out their YouTube channel and found it very helpful for learning to use the various features!

Pricing  

HeyGen Pricing
  • The Free plan: Provides one free credit, 1-minute maximum video duration, one seat, 120+ human avatars, 300+ voices, and basic features. 
  • The Creator plan: Costs $29 per month and includes 15 credits per month, a 5-minute maximum video duration, one seat, and premium features like PowerPoint import and auto-captions. If you pay yearly, it’s just $24/month.
  • The Business plan: Priced at $89 per month, offering 30 credits per month, 20-minute maximum video duration, 3 seats, and additional advanced features like 4K resolution and priority video processing. If you pay yearly, it’s $72/month.
  • The Enterprise plan: Customized and provides all the benefits of the Business plan along with tailored solutions and dedicated support.

My Experience With HeyGen

HeyGen was honestly not the easiest program to use, but it was worth the learning curve due to how amazing its avatars are! I think it’s a bit trickier than some of the programs as it just has so many more features.

The interface is quite similar-looking to the interface of Canva, so if you know that program, you’ll find HeyGen a bit easier to use. Here’s how the interface looked when I was creating my video:

HeyGen interface

You’re able to customize pretty much every part of your video. I added a stock image as a background, a stock video, and then an AI-generated image (the cavemen!). I also added one of my own slides as a background to one part of the video. I honestly loved everything about HeyGen, once I sort of found my way around the program.

I was able to click the “text” button to add text to a slide, I was able to choose a “public avatar” (make sure you don’t choose one with the little yellow sign at the bottom left when you are creating a free video – those are only for paying customers).

I was able to change the speed and pitch of the voice (if I wanted to), and the position of the avatar within each slide. HeyGen is very customizable! Here’s the finished video, using one of their avatars.

NOTE: This video was created by me using HeyGen. The script was written by me.

Bottom Line  

Overall, HeyGen is my top choice for a alternative for Synthesia if you are a solopreneur, small-to-medium sized business, or an influencer. HeyGen is hands down the best AI avatar generator out there right now. Check it out for yourself by watching all of the videos I created when doing the research for this article! Their avatars look the most lifelike, and they sound -almost- human-ish!

HeyGen is super easy to use, includes tons of images, videos and music, and has the most realistic voices of any of the programs that I tried. Take advantage of the free trial and give it a try – you have nothing to lose by exploring HeyGen!

2. Colossyan – Best For Multiple Avatars in a Scene

Colossyan video generation software, an alternative to Synthesia

Quick Take

Colossyan is a great alternative to Synthesia. It has lots of avatar options, they look reasonably realistic, and you can even use up to four avatars in a video (with a Pro subscription).

It’s definitely meant more for businesses, rather than for solopreneurs or those looking for social media videos. It’s got lots of great features that will work for educators and businesses.

Top Features  

  • Colossyan offers Avatar Conversations, enabling you to create interactive learning experiences that foster student engagement.
  • Has a great 14-day free trial with 5 minutes of video and 5 scenes.
  • Colossyan is unique in that it allows you to include up to four AI avatars in your videos. This can help make the video more interesting to watch for your viewers. It was fun to make the avatars have conversations together!
  • I liked how you can change the emotional tone of some of the avatars (i.e., ‘happy’ vs. ‘excited’) – this helped add some interest to the video.

What I Like About Colossyan

  • Colossyan is one of the easiest-to-use AI avatar programs that I’ve tried.
  • Has great chat support – I had difficulty rendering one video and they responded to me within the hour.
  • Colossyan has great branding features, which is great for larger businesses.
  • The Colossyan interface is clean and uncluttered. It’s very easy to learn and use.

What I Don’t Like About Colossyan

  • Their background music options are very limited. However, you can upload your own music.
  • The mouth movements of their avatars looked a bit “off” in my videos.

My Experience With Colossyan

I found Colossyan very easy to use. I loved that it has easy to find “save” and “undo” buttons. There were lots of templates to make creating the video easy.

Colossyan is unique in that it allows more than one avatar in each scene – up to a maximum of 4. When I made the video below, I used a few different avatars so I could get a feel for how realistic they look. Colossyan’s avatars look reasonably human-looking.

I liked that they move slightly in human-like ways (for example, they move their hands at random times, and the bodies sway back and forth slightly, making them look a little less “robotic”).

Here’s what the interface looks like when you are creating your video:

Colossyan interface

I thought it was interesting that you can change the emotion of some of the avatars (“happy” vs “excited”), but I did note that the music choices were very limited.

When the video was generated, I noticed that the mouth movements of the avatars were “off” by quite a bit. The bodies looked pretty good, but the faces weren’t amazing. Take a look at the video below to see how the avatars turned out!

NOTE: This video was created by me using Colossyan. The images were created by me in Canva, and the script was written by me.

Bottom Line  

Overall, Colossyan is a fantastic AI avatar generator for larger businesses. It’s fantastic for training videos for employees, as it has lots of features to keep viewers engaged (i.e., more than one face in the videos, you can change the emotional tone of the voice, lots of templates to choose from). I wasn’t impressed with the mouth movements of the avatars, but the body movements looked quite realistic.

One thing I really noticed was that there there was no “undo” button in the interface. I also found it difficult to know how to “save” the video as I went – in the end, I had to click the “back” button and it would say “do you want to save your video?” and I would say “yes”.

Deepbrain Interface

I did appreciate that there is a chat function that I could use to contact support.

In the end, their avatars were not my favorite. They looked even less “realistic” than some of the other choices in this list. Take a look at the video below to see for yourself!

NOTE: This video was created by me using Deepbrain, and the script was written by me.

Bottom Line  

Overall, Deepbrain is a standard AI avatar generator program. Where it shines is with the capability to have real-time conversations with the avatars. I recommend looking into it if you want to have that option for your online customers!

My Experience with Synthesys

Synthesys had the smallest number of AI avatar choices (about 30) of all the programs I tried. The avatar mouth barely moves in the video, although it did do some realistic-looking hand gestures.
