Strong product overall
Pleasantly surprised by the quality. The onboarding flow was smooth and I was productive from day one. I use this daily and it's become essential to how I work. My team adopted this immediately after I shared it with them. I'd love to see better export options.

Solid product, recommended
Really solid tool overall. Customer support responded within hours and solved my issue. The free tier is genuinely generous compared to competitors. The AI doesn't just suggest — it learns from my preferences over time. Occasional slowdowns during peak hours. Best tool in this category, hands down.
