Useful and reliable

Very good, with a few rough edges. I use this daily and it's become essential to how I work. Reduced the time I spend on this task by about 70%. It handles edge cases better than anything else I've tried. I'd love to see better export options.

Decent but has room to grow

Works okay, not life-changing. The collaboration features are genuinely well thought-out. My team adopted this immediately after I shared it with them. Occasional slowdowns during peak hours.

Had some issues

Customer support left a lot to be desired. I've tried 5 similar tools and this one is clearly the best in class. The AI doesn't just suggest — it learns from my preferences over time. Wish the free tier had slightly higher limits.
