Wait, another project management tool? What makes this different from Asana, Monday, or the 500 others?

Honestly intrigued by the AI task breakdown feature. We waste so much time in planning meetings.

SkepticalSarah15
Pricing seems steep for what you're offering. Can you justify $49/month when Trello is free?
