Pricing.
One paid plan. $15 a month, cancel whenever. Everything the features page says Inergy does today is in it, for one campaign: unlimited questions, live sessions and recaps, and five imports of your notes a month.
There's a free plan too. Same brain, same live layer, for one campaign. Each month it includes 30 questions to the brain, one live session, one import of your notes and one written-up recap. Enough to know whether it's for you before you pay for it.
Nothing costs extra yet. See "Coming" on the features page for what might.
