Had some issues
Disappointed with the experience. Integration with my existing tools was seamless — no friction at all. The interface is intuitive enough that I didn't need to read any docs. Customer support response times could be faster.

Good for some things, not others
Good for some things, lacking in others. The onboarding flow was smooth and I was productive from day one. It integrates well with VS Code / Slack / Notion — my daily drivers. A few missing integrations I'd like to see added.
