What I like most about HeyGen is how realistic the AI avatars are and how natural the voiceovers sound. The platform is straightforward to use, and it lets me create professional-looking videos quickly without needing advanced video-editing skills. Review collected by and hosted on G2.com.

One drawback is that some of the more advanced customization features for avatars and voiceovers are only available on higher-tier plans. I’d also like to see a wider range of options for avatar expressions and gestures, along with more voice-personalization controls, so the videos can feel even more natural and tailored.

What I like best about HeyGen is how quickly it turns ideas and scripts into professional-looking videos. The platform is intuitive, the avatars look realistic, and the voice and language options make it very useful for marketing, training, presentations, and client communication. It helps me create video content much faster than traditional production. Review collected by and hosted on G2.com.

There is not much I dislike about HeyGen, but some advanced customization options could be improved. For example, more detailed control over avatar gestures, facial expressions, scene transitions, and branding elements would make the final videos even more flexible. Also, for some projects, pricing can become a consideration when producing a higher volume of videos. Review collected by and hosted on G2.com.

HeyGen is the first AI tool I used to start creating digital avatars. I’m a real estate agent. This feature saved me a lot of stress when I had to record a “talking head” video every week with news and special offers. My company required it, but now that I’ve left, I don’t need this feature anymore. But I’m grateful to HeyGen for those six months of peace of mind without having to spend time recording.

I use a lot of digital services, and this places a significant financial burden on my growing business. The main challenge with using HeyGen isn’t technical; it’s simply the cost. Review collected by and hosted on G2.com.

What I like most about HeyGen is that I could import a voice I created in another program, so I didn’t have to recreate it from scratch. I also really appreciate how realistic her voice sounds, especially with the enhanced emotion, and how clearly her mouth articulates the words when she reads the scripts I write.

What I don’t like is that there isn’t a way to control who’s speaking in a clip when more than one character is visible. After several attempts (and wasted credits), I still couldn’t get the results I wanted and ended up settling for a static image with an audio track instead. That kind of soured my Mother’s Day clip.

I love the AI agent in HeyGen. It helps me avoid burnout and fatigue because I don't have to repeat myself constantly. The ability to edit scene by scene is great, and I don't have to start over entirely. The ease with which I can reduce 50 hours of training to just 5 hours of work on a video is impressive. The initial setup was very easy, and I was able to integrate it with ChatGPT smoothly. Review collected by and hosted on G2.com.

I find it takes me a few tries to get overlays or pronunciation right. I would keep them more relevant to the training. Review collected by and hosted on G2.com.

I love the avatar quality and realism in HeyGen, especially the custom instant avatars that are shockingly lifelike. The voice cloning is impressive as it captures my actual tone, pacing, and emotion. The no-shoot workflow is fantastic; I can go from script to avatar video in minutes without ever touching a camera. Also, the initial setup was very easy, making it really accessible. Review collected by and hosted on G2.com.

While HeyGen is a powerful tool, there are a few areas where users, myself included, see room for improvement. These often come down to the realism of the avatars. Although the newest avatar V model is a significant leap forward in realism, further improvements are needed. The areas of improvement are not about fundamental flaws but rather fine-tuning the nuances of human expression and performance. While avatar V can generate micro-expressions, users have noted that avatars can feel stiff, emotionless, or lack the warmth of a real person. Review collected by and hosted on G2.com.

I used HeyGen in a course on AI held at the University of the Third Age (UNITRE) in Turin (Italy). Particularly useful was the ability to use different Avatars (myself, AI-generated figures) assigning them brief spoken interventions with an impressive presence effect and lip synchronization. I also produced short films where I mixed my Avatar with clips extracted from science fiction movies useful for explaining AI behaviors. Review collected by and hosted on G2.com.

I had some difficulty in obtaining a video that adhered to the related script: HeyGen showed a certain tendency to interpret the instructions in its own way. However, I believe this is part of the normal learning curve. Review collected by and hosted on G2.com.

What I like most about HeyGen is how quickly it allows creative ideas to become cinematic experiences. The new Workbench concept is especially powerful because it helps organize scene structure, emotional pacing, and visual consistency in a much more natural way. It feels less like using separate AI tools and more like directing a real creative production workflow. Review collected by and hosted on G2.com.

Sometimes generating high-quality cinematic results can take multiple iterations and prompt refinements, especially for more complex storytelling scenes. However, this is currently common across most AI video generation tools. I would especially love to see faster rendering times, improved scene consistency between shots, and even stronger control over cinematic continuity and object persistence in longer creative workflows.

Ease of use, ease of implementation, customer support, frequency of use, number of features, and ease of integration. Review collected by and hosted on G2.com.

The biggest issue is transparency around feature limitations and beta status.

For example:

* Seedance Avatar Shots does not support Voice IDs or voice clones, but this is not clearly communicated before generation.

* Presenter Avatar V appears to still be in beta, but there is no obvious beta label or warning visible during usage.

* Some experimental features can produce highly unpredictable outputs, including incorrect duration or unexpected speech behavior, while still consuming large amounts of credits.

For users working on professional projects, especially cinematic or timing-sensitive videos, these limitations matter a lot because they directly affect planning, workflow, and credit usage.

I also think there should be clearer expectations around:

* which features are stable for production use

* which features are experimental

* what kinds of outputs are currently unreliable

* whether timing controls are approximate or strict

Another issue is that some features feel visually connected inside the platform, which creates the expectation that workflows are compatible across tools, even when they are not. For example, using avatars + voice clone + cinematic generation feels like a natural expectation from a user perspective. Review collected by and hosted on G2.com.

I like that HeyGen is easy to use for creating professional-looking academic tutorial videos without needing a full studio setup. I use it for educational content, including Research Methodology, Biostatistics, manuscript writing, faculty training, and student learning support in allied healthcare sciences.

The avatar and AI video workflow is helpful because it lets me turn prepared teaching scripts into clear video lessons. It is especially useful when I need to explain repeated academic topics in a consistent and engaging way for students and faculty. For educators, this saves time and makes it easier to prepare structured tutorial videos, orientation content, and training material.

The right-side “Overall Review Depth” is only showing which topics your answer covers. You don’t need to separately answer those points now. Review collected by and hosted on G2.com.

The main area I would like to see improved is clearer information on credit usage, especially when creating longer academic videos or using PPT/PDF-to-video workflows. Sometimes it is difficult to estimate how many credits a project will need before generating the video.

For educators, more ready-made templates for teaching, tutorials, orientation sessions, and academic training would also be helpful. Long lesson workflows could be smoother, especially when working with multiple scripts, slides, voice files, and avatar videos. Overall, these are not major issues, but improving them would make HeyGen even more useful for educational users. Review collected by and hosted on G2.com.
