What Real Users Say
“Heygen App Difficult to use. Unauthorised charges, I paid for one off project, however two months later when I checked my account Heygen were debiting unauthorised large amounts from my bank account.”
Verified Trustpilot review“Our intention was to invest in a package with more minutes, but the only option available beyond the Creator plan... is the Enterprise plan, which costs a staggering [amount], with no intermediate options.”
