Very useful, mostly polished
Very good, with a few rough edges. The customization options let me tailor it to my exact workflow. The output quality surprised me — it actually sounds human. The API is well-documented and easy to work with. Some features feel half-baked — hopefully they'll improve. Five stars — no hesitation.

Has potential, needs polish
Works okay, not life-changing. Integration with my existing tools was seamless — no friction at all. The outputs require minimal editing — saves so much back-and-forth. Wish the free tier had slightly higher limits.

Very useful, mostly polished
Strong product with room to grow. The onboarding flow was smooth and I was productive from day one. Pricing is fair for the value you get. A few missing integrations I'd like to see added. Will continue using this long-term.

Recommended for anyone in my field. The interface is intuitive enough that I didn't need to read any docs. The AI doesn't just suggest — it learns from my preferences over time. Customer support responded within hours and solved my issue. Will continue using this long-term.
