Mixed experience overall

Mixed feelings, but ultimately positive. I've recommended this to at least 10 colleagues already. The onboarding flow was smooth and I was productive from day one.

Strong product with room to grow. Performance is fast — no noticeable latency even on large inputs. The accuracy has improved significantly with recent model updates. A few missing integrations I'd like to see added. Keep up the great work, team.

Happy with my subscription

Recommended for anyone in my field. It integrates well with VS Code / Slack / Notion — my daily drivers. Reduced the time I spend on this task by about 70%. I've tried 5 similar tools and this one is clearly the best in class. The mobile experience could use some work. Keep up the great work, team.
