A while back I did an interview with Grant Lee, the CEO of Gamma. He asked me what I'd add to the tool. I told him that as someone who used to be terrified of public speaking, my dream feature would be an AI avatar that could just take over my video presentation for me. Deliver the whole thing while I hide in the green room.
Well. HeyGen just launched a Gamma integration. I'm not saying Grant listened to me specifically, but I'm not not saying that either.
If you've been looking for a way to make a video presentation without recording yourself, setting up lighting, or doing seventeen takes because you said "um" too many times, this might be exactly what you've been waiting for.
What the HeyGen x Gamma Integration Does for Video Presentations
The idea is simple. Instead of building slides somewhere else and importing them, you can now generate a Gamma-powered presentation directly inside HeyGen and immediately turn it into an avatar-narrated video presentation, all in one place. Prompt to slides to video, no tool-switching required.
It's essentially an online video presentation maker that handles the design, the script, and the narration in one go. No PowerPoint, no Keynote, no Canva, no stitching things together afterwards. Think of it like a screen recorder and a presentation tool had a baby, but the AI does all the work.
One thing worth noting: this integration lives on the HeyGen side only. Gamma hasn't added a HeyGen integration on their end yet, so you'll be starting from HeyGen, not Gamma.
How I Tested It to Make a Video Presentation
I used my go-to test prompt: "AI tools for SMEs."
I use this one deliberately. It gives the tool enough room to roam, but it also tells me a lot. If the output is generic or surface-level, that's a sign the AI isn't really understanding the brief. It's the same prompt I use across all my AI presentation tool reviews on this site, so I can compare results like for like. No template, no storyboard, just a prompt.
The Settings: How to Make Video Presentations Your Way
Before HeyGen generates anything, you configure a few things. Here's what I set:
- Number of slides: 5-10
- Amount of text per slide: Minimal, Concise, Detailed, or Extensive (I went Concise)
- Audience: small business owners
- Tone: friendly, funny
- Language: English
- Additional instructions: "create it with Gamma"
- Avatar: I selected my own, which I created from a photo
You also toggle whether you want AI to generate a script automatically. I left that on. This is what controls the spoken narration -- the words your avatar will actually say for each slide. You can edit all of it afterwards.
What the Generated Video Presentation Looks Like
Once it generated, I immediately recognised the visual format. That's Gamma. The layout, the way content is structured, the clean design -- it has Gamma's signature all over it. If you've ever used Gamma to make a video presentation or a pitch deck, you'll know exactly what I mean. The slides look good, which isn't always a given with AI-generated content.
Alongside the slides, HeyGen produces a full spoken script for your avatar to deliver -- one section per slide. Everything is editable before you hit generate. You can rewrite the script, swap images, adjust text, add animations, transitions, or other visual elements. The format is flexible enough that you can make it easy to customise for your brand.
This is also where you can record a video presentation with your own voice instead of the AI clone, upload your own audio, or adjust the avatar delivery style. There's a lot of control once you're inside the editor.
The Wait
I hit generate and then waited. And waited. The whole thing took around 10 minutes, and sat at 99% for what felt like an eternity. Not ideal if you're in a rush, but not a dealbreaker either -- you're not doing any of the work during that time. AI is handling the slides, the script, the narration, and the avatar. For a complete video presentation from a single prompt, 10 minutes is still faster than doing it manually with a webcam and a screen recorder.
The British Accent I Definitely Didn't Mean to Give Myself
I previewed the AI-generated video presentation and had to laugh. HeyGen had cloned my voice with a British accent. Which is not my accent. Apparently at some point during setup I chose it and never changed it.
You can fix this in the voice settings -- there are options for accent, tone, and delivery style. I left mine as is because it made me laugh. But if you're planning on sharing your video with clients or using it for onboarding, worth double-checking before you hit generate.
What I Liked About Making a Video Presentation This Way
The presentation itself is solid. Everything is editable so it's not a take-it-or-leave-it situation. You can swap images, rewrite the script, adjust the format, and customize the visual design without starting over. I had zero design work. No blank slides, no fighting with layouts, no choosing fonts.
The free plan is also genuinely generous. You get three one-minute video presentations for free. That's enough to test the feature properly and decide whether it works for your use case before committing to a paid plan.
For anyone watching a video presentation rather than sitting through a static slideshow, this is more engaging. A talking avatar delivering the content keeps your audience's attention in a way that a wall of bullet points just doesn't. It's a simple way to increase engagement and make your presentations more fun to watch asynchronously -- think Loom, but the presenter is AI-generated.
