Pricing
Simple, honest pricing.
Start free. Upgrade when your work demands it. In MAINS Council you can use your own key for any of the four AIs on any plan; in threads and Klaustrum, your plan decides which of them you dispatch.
People you bring into a Council never pay: the AI replies their messages trigger spend your allowance or run on your own keys, exactly like yours.
