Pros & Cons
Canva AI
Pros

- Brand Kit ensures all AI-generated content matches your visual identity automatically
- Bundled pricing is cheaper than subscribing to separate AI image, video, and copy tools
- Team collaboration features with comments, approvals, and version history work seamlessly with AI content
- Template library with AI enhancement means non-designers can produce professional results
Cons
- Image generation quality trails behind Midjourney and DALL-E 3 for artistic or photorealistic needs
- Video generation is basic compared to dedicated AI video platforms like Runway
- AI outputs tend to be safe and predictable - not ideal for creative or boundary-pushing work
- 500 Magic Media uses per month can feel limiting for heavy content production teams
- Advanced design needs still require exporting to Photoshop or Illustrator for finishing

Cons

- Requires a dedicated NVIDIA GPU with 8GB+ VRAM for practical local use
- Default output quality is inconsistent without careful prompting and model selection
- No built-in user-friendly interface - you need third-party tools like ComfyUI
