Pros & Cons
Synthesia
Pros
- Fastest way to produce professional training and corporate videos - script to finished video in minutes
- 140+ language support with natural-sounding voices makes global content creation trivially easy
- 230+ avatars with convincing lip sync and gestures that actually look human
- Custom avatar and voice cloning let you scale a specific presenter across hundreds of videos
- Massive time and cost savings over traditional video production for repetitive content types
Cons
- Limited to talking-head format - don't expect cinematic or creative video styles
- Per-minute video costs add up fast for teams producing high volumes of content
- Built-in editor is basic - complex projects need finishing in external tools
- Some avatars still hit the uncanny valley, especially with complex facial expressions
- No real-time generation - you submit a job and wait for rendering, which can take minutes
Leonardo.AI
Pros
- Custom model training lets you create consistent visual styles unavailable in any other consumer AI tool
- Generous free tier with 150 daily tokens is the best free offering among major AI image generators
- Community model library offers thousands of specialized styles you can use immediately
- ControlNet support with pose, depth, and edge guidance gives serious artists the control they need
- AI Canvas with layers provides a real workspace for iterative creative production
Cons
- Default image quality without fine-tuned models can feel generic compared to Midjourney
- Learning curve is steeper than competitors - getting great results requires understanding models and parameters
- Video generation is still basic and limited to short animated clips from still images
- Token system can be confusing - different generation settings consume wildly different token amounts
- The interface feels cluttered with options, which can overwhelm new users who just want to type a prompt
