Okay product, not amazing
Has potential, but needs polish. It integrates well with VS Code / Slack / Notion — my daily drivers. It integrates well with VS Code / Slack / Notion — my daily drivers. The UI takes some getting used to.

Changed how I work completely
This is exactly what I was looking for. The interface is intuitive enough that I didn't need to read any docs. Integration with my existing tools was seamless — no friction at all. The accuracy has improved significantly with recent model updates.

Needs a lot of improvement
Disappointed with the experience. The customization options let me tailor it to my exact workflow. I've recommended this to at least 10 colleagues already.

Has potential, needs polish
Mixed feelings, but ultimately positive. It handles edge cases better than anything else I've tried. The recent updates have addressed most of my initial concerns. The mobile experience could use some work.

Does the job well
Mostly great, minor complaints. The AI suggestions are incredibly accurate and save me hours every week. The free tier is genuinely generous compared to competitors. Wish the free tier had slightly higher limits. A staple in my tech stack now.

Really good — a few things to improve
Very good, with a few rough edges. I've recommended this to at least 10 colleagues already. Pricing is fair for the value you get. I'd love to see better export options. Looking forward to seeing how it improves.

Best-in-class, period. Works consistently across all my devices and browsers. The onboarding flow was smooth and I was productive from day one. The ROI was clear within the first week of using it. A staple in my tech stack now.
