About this review: , I was looking into AI video tools for our team and was incredibly confused when I saw a ton of search results for “Hygen AI”. I found out that the app name is actually HeyGen, and was able to get access to it for our team to see for ourselves what the tool is all about. The first thing that stood out to me was how easily I could generate video content simply by inputting a script.
There are no filming or acting requirements, and all the hard work of editing is taken away. The following sections will outline my firsthand experiences of the tool, from how to use it, the pricing, and everything in between, so you can decide if the tool works with your content generation needs.
Quick Answer:
HeyGen (frequently referred to as “Hygen AI” in searches) is a cloud-powered tool for synthetic media generation, which does not require actors, cameras, or editing to produce realistic avatar videos. Users select an avatar, input a script, and pick a voice to generate videos in under 5 minutes from an online library of over 100 languages.
It is especially useful to marketers, teachers, and content creators who require quick and large scale video production. However, it is not as ideal for the production of emotionally driven or dramatic pieces of cinematic video. Average rating is 4.5 out of 5 stars.
What Is Hygen AI?
Hygen AI is often mistakenly used in place of HeyGen, which is an AI video creation software that helps users create videos with talking avatars. Using the application, people can create realistic videos without the need of video equipment, an acting crew, and editing skills. Users write down a script and inform the software of which AI avatar to generate.
The software produces realistic videos with voice and facial expressions. The application is used for several different purposes, including marketing, training, education, social media content, and can be used in more than one language.
How to Get Started with Hygen AI (Step-by-Step)
Set Up an Account
Go to the Hygen AI (HeyGen) website to sign up with an email or Google account. Verify the email, set up a basic profile, and then log into the portal to begin making AI videos.
Learn the Dashboard
Get familiar with the dashboard after logging in. You will see the tools you need for working with Avatars, Templates, Scripts and Video Settings. Knowing the dashboard helps you select the tools you need to create professional AI videos.
Pick an AI Avatar
Choose an AI Avatar from the variety of options available. You can also create your own Avatar. Choosing an Avatar helps to create video content that is professional and engages your audience.
Paste or Write the Script
Type the message you want the avatar to deliver. Make it easy for the avatar to deliver the message and maintain a conversational tone. You can also make a delivery style and pacing adjustment to fit the purpose of the video.
Choose Voice and Language
Pick an AI Voice and language from the many options available. Hygen AI does many voices and this helps you deliver content in a language that fits your target audience. Choosing a voice that matches your avatar helps to make the video more engaging.
Adjust Video Settings
Customize Settings for the Background, Subtitles, Music, and Aspect Ratio. These tools let you tailor a video to fit specific requirements whether they are a professional presentation, a social media post, or your corporate branding.
Generate Downloadable Video
Press “generate” to process the video using AI. In just a few minutes, the final video is generated. You can preview your video, make edits if you want to, and download your video or directly share it on your social media.
How It Works (Step-by-Step)
Script Input by the User – This step allows you to build the video content by typing or pasting the text that you want your AI avatar to verbalize.
Text Analysis – The analysis by the platform breaks your text into components to recognize the verbal tone, speech cadence, and the style of language so that text-to-speech and video generation can be done seamlessly.
Choose Your Avatar – This step allows you to choose a digital avatar from the available library or create your own. The chosen avatar is the visual representation of the speaker in your video.
Speech in Your Chosen Language – In this step, your script is converted to speech in the chosen language with the chosen accent to the avatar.
Realistic Video Animation – The voice generation system integrates facial expressions, movements, and lip-sync to the generated voice to create a photo-realistic animation to a video.
Video Compilation – The generated voice and effects with the chosen avatar and background are compiled to create a processed video.
Edit and Share – You can make edits and share the generated AI video after previewing it.

HeyGen Mobile App
HeyGen does not yet have a native mobile app with full functionality like its desktop/web version. At this time, the only way to use HeyGen on mobile is through their mobile friendly web version. With this version, users are able to create, edit, and generate AI videos directly from a mobile web browser.
Many features of HeyGen like script input, avatar selection, and video preview are accessible in the mobile version. However, video editing and rendering functions have yet to be optimized for mobile and are much better done on the desktop version.
Because of this, the convenience of the mobile editing version of HeyGen is better suited for minor edits and content previews, though this version falls short for time intensive editing and professional grade video generation.
