Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Resemble AI
- The Team plan jumps to $350/month for just 5 seats, a steep increase from the free Flex tier.
- Detection accuracy rates (99.5% audio, 98% video, 96% image) mean some deepfakes can still go undetected.
- SSO and org-wide security features are only available starting on the $1,000/month Business plan.
- Voice cloning of another person's voice requires explicit consent verification, adding friction to some workflows.
Spline
- AI generation features produce inconsistent and often distorted results, failing at basic depth perception tasks
- Limited to simpler designs - not suitable for high-poly, detailed production models
- Performance degrades with complex scenes containing many objects and materials
- Limited non-Apple platform coverage compared to cross-platform design tools
- Tutorials are either too fast for beginners or too basic for advanced users
