Worth every cent
This is exactly what I was looking for. The interface is intuitive enough that I didn't need to read any docs. The ROI was clear within the first week of using it. Best tool in this category, hands down.

Decent but has room to grow
Decent tool, not without issues. The interface is intuitive enough that I didn't need to read any docs. Occasional slowdowns during peak hours.

Does the job well
Genuinely useful — glad I tried it. The API is well-documented and easy to work with. The AI doesn't just suggest — it learns from my preferences over time. The learning curve was steeper than expected. Five stars — no hesitation.

Expected better
Lots of bugs and issues. I've recommended this to at least 10 colleagues already. My only complaint is the pricing could be more competitive.

Okay product, not amazing
Has potential, but needs polish. Customer support responded within hours and solved my issue. My team adopted this immediately after I shared it with them. Customer support response times could be faster.

Not worth it for me
Customer support left a lot to be desired. The outputs require minimal editing — saves so much back-and-forth.

Had some issues
Not what I expected. Integration with my existing tools was seamless — no friction at all. It handles edge cases better than anything else I've tried. Wish the free tier had slightly higher limits.
