HeyGen
AI Video & Voice
HeyGen generates a video with an avatar reading a script, which suits training, localisation and social clips that would otherwise need a camera and a shoot. Avatar quality varies by plan and language, and what you get is hosted synthetic video rather than footage you own.
Strengths
- Script to presenter video without filming
- Avatars and voiceover in many languages
- Templates for common video formats
- Editing the script re-renders the video
Trade-offs
- Free tier caps video length and features
- The better avatars and voices sit on paid tiers
- Synthetic presenters suit some audiences better than others
