ReelFlow vs Synthesia, HeyGen and AI video generators
AI video generators like Synthesia and HeyGen make a video – you type a script, an AI avatar delivers it. ReelFlow is the layer above: it turns video, real or AI, into interactive on-site flows that route and convert your visitors.
Are Synthesia and HeyGen competitors to ReelFlow?
No – they're a different layer of the stack, and in practice they're inputs to ReelFlow rather than rivals. Synthesia and HeyGen generate a video. ReelFlow is where video becomes an interactive experience on your website. You don't choose between a tool that makes a clip and a tool that turns clips into a converting journey – you can use both, and ReelFlow can take input straight from the generators.
Generation and implementation: two different layers
The clearest way to see it is as two layers of the same stack.
Generation — Synthesia, HeyGen and similar tools. Type a script and an AI avatar delivers it, in many languages, ready in minutes without a camera. This is the fastest way to produce a lot of video, and it's exactly what these tools are built for: training modules, onboarding, product explainers, internal comms, localised at scale. What they don't do is turn that video into something interactive on your website.
Implementation — ReelFlow. ReelFlow takes video – filmed footage of your team, or an AI Stand-In – and turns it into an interactive experience woven across your site: branching flows where each visitor chooses their path, is routed to what's relevant, and is guided towards an enquiry or registration.
Where AI fits at ReelFlow
AI is one small part of ReelFlow, not the headline. The core is interactive video built on authentic, human footage – because for a B2B buyer deciding whether to trust you, real people do the work.
Where AI does help, ReelFlow's AI Stand-In is an authentic stand-in of a real person on your team – trained on them, and able to plug into generation models like Synthesia or HeyGen – so it still looks and sounds like someone your buyer can trust. It's a deliberately narrow choice: an authentic AI of your own people for B2B, not a library of generic avatars. Pro-authenticity, and pro-AI where it earns its place.
Can you use them together?
Yes – that's the natural fit. Use a generator to produce clips at scale; use ReelFlow to turn video into an interactive experience that converts on your site. Different layers, different jobs, sitting together comfortably. Put simply: if the task is making and localising a lot of video, reach for a generator like Synthesia or HeyGen; if the task is getting your website to engage and convert B2B visitors, that's ReelFlow – and the two work best in sequence.

45s
Increase in time on page
"We have seen the bounce rate go down by 7% and time on our homepage has increased by 45 seconds."
Bringing something new to the table
"Multiple people have come onto calls with me and one of the first things they've said is, "Oh, I've seen that video on your website. That's cool!" That's just the best kind of attribution.
There is nothing better than getting on a sales call with someone where they actually say something to you like, "I found you because of this," or "I like this." That's the best metric I can get in terms of positive signals from the market."
Game
changer
"People don’t buy from businesses, they buy from people. To actually see and hear from the person you’re going to be working with is a total game-changer."
Standing out from the crowd
"The thing that I love the most about ReelFlow is the idea that a human you might want to do business with has thought about you, the audience, and thought about what they want to convey.
In this world of robots, having that interactive 'choose your own adventure' that features a real person is quite a nice and personal thing. It’s a way of standing out from the crowd and starting that personal relationship from the very first time they visit your website"
Frequently asked questions
No. Synthesia and HeyGen generate video from text using AI avatars. ReelFlow is the layer above – it turns video, real or AI, into an interactive experience on your website that routes and converts visitors. One makes the clip; ReelFlow puts it to work.
Not really – they're a different layer, and in practice they're inputs to ReelFlow. A generator produces a clip; ReelFlow turns video into a converting on-site experience. ReelFlow's AI Stand-Ins can even plug into models like these.
AI is one small part of what ReelFlow does. The core is interactive video built on real human footage. Where AI helps, the AI Stand-In is an authentic stand-in of a real person on your team – not a generic avatar.
It's an authentic AI version of a real person from your team – trained on them, and able to draw on generation models like Synthesia or HeyGen – so you can keep producing video in their likeness without filming every clip. It's built for B2B trust, which is why it's a stand-in of your own people rather than a stock avatar.
Yes. Whether a clip is filmed or generated, ReelFlow is where it becomes an interactive, branching experience on your site. The generators are one of the ways video gets made; ReelFlow is where it goes to work.
It's built around real, human video, because that's what earns trust with a B2B buyer. AI Stand-In is available where it helps, as an authentic version of your own team – so even the AI is a real person, not a synthetic presenter.
