HeyGen
AI Video
HeyGen is an AI video creation platform centered on avatars, voices and localization. It can turn text, an image, a presentation or a PDF into video with an avatar, voiceover, captions, translation, lip-sync and multilingual versions. In a Spybox workflow, HeyGen mainly helps test a product angle, UGC video, training message or sales sequence with a virtual presenter before setting up a full shoot.
What is it for?
- Create AI avatar videos for UGC ads, product demos, onboarding, training, sales outreach, tutorials and social media content.
- Produce or localize videos in multiple languages with dubbing, cloned voice, captions, lip-sync and tone adaptation.
- Quickly test several scripts, faces, voices, lengths, languages and formats before deciding whether a human or studio version is worth producing.
What to check
HeyGen can save a lot of production time, but synthetic avatars and voices need strict review: consent, likeness rights, message credibility, translation and ad compliance.
- Check consent for represented people and rights for voice, face, image, logo, product, music, script and visual references.
- Review translations, names, numbers, product claims, required notices and cultural nuance before publishing.
- Watch human realism: lip-sync, eye contact, gestures, accent, emotion, artifacts, audience transparency and cost per minute.
How to use it when deciding
- Start from a Spybox signal, write a short scene and decide whether the goal is product proof, explanation, localization or spokesperson testing.
- Create several variants with avatar, voice, language, hook, length and format, keeping only the versions that feel credible on mobile.
- Compare results with retention, clicks, replies, comments and cost per test before producing a final version.
