Attribute	Slack	Todoist
Plans	Free $0 Small teams trying Slack.	Beginner Free Anyone with a simple list.
	Pro $7.25/user/mo billed yearly ($8.75 monthly) Small teams that want basic AI.	ProOur pick $7/mo, or $5/mo billed yearly Anyone who wants more projects and the calendar view.
	Business+Our pick $15/user/mo billed yearly ($18 monthly) Teams that want the full AI set.	Business $10/user/mo, or $8/user/mo billed yearly Small teams sharing a workspace.
	Enterprise+ $45/user/mo billed yearly Large companies with many tools.
Which plan to pick	If your team already pays for Pro, try the basic AI first. Move to Business+ when you want AI search, the Slackbot agent and daily recaps, which is where the real time saving is. New teams get 50% off Pro or Business+ for 3 months if they upgrade in the first week.	Beginner is fine until you hit the five-project wall. Pro on the yearly plan is the obvious move after that. Business is for teams who want a shared space; it is not a substitute for a real project tool.
