A must-have for any professional

Can't imagine working without it now. The recent updates have addressed most of my initial concerns. It integrates well with VS Code / Slack / Notion — my daily drivers. The ROI was clear within the first week of using it.

Best in class, no question

Best-in-class, period. The ROI was clear within the first week of using it. The free tier is genuinely generous compared to competitors. I've recommended this to at least 10 colleagues already. Five stars — no hesitation.
