Blank idea → plan → MVP brief
IdeaBriefly takes a sentence and returns a structured brief: the plan, the product name, the flow, and the acceptance bar. No model key. Sprint seats target about 72 hours when they open — that is a target, not a ship guarantee. Paid seats are coming soon.

Drop the idea
A sentence is enough. Chips if you do not have one yet.
02
Write the plan
Problem, audience, value, risks, and a scoped next-step list.
03
Leave with an MVP brief
Name, flow, pages, stack, and acceptance criteria for a first slice.
