Mixed experience overall
Useful but frustrating at times. I've tried 5 similar tools and this one is clearly the best in class.

Incredible — highly recommend
Can't imagine working without it now. It handles edge cases better than anything else I've tried. Integration with my existing tools was seamless — no friction at all. The outputs require minimal editing — saves so much back-and-forth. Would recommend to anyone in my industry.

Okay product, not amazing
Good for some things, lacking in others. The AI doesn't just suggest — it learns from my preferences over time. The learning curve was steeper than expected.
