Two tools. That's the whole server.
With just these two, your coding agent can pick your paywall, price your plans, plan your onboarding, write your paywall copy, and cut your churn. It asks, gets a sourced answer, and builds it in.
askAny onboarding, paywall, pricing, or retention question. Returns sourced claims with their dataset and year, plus the deciding condition when experts disagree.
freelist_topicsThe knowledge domains the brain covers, with the claim count per domain. Useful for discovery.

Every money screen, answered
The moments your agent stops guessing and pulls a real benchmark instead. A few of the hundreds it can ask.
“Hard paywall or a free trial for my app?”
Hard paywalls convert about 5x better: 10.7% vs 2.1% download-to-paid at D35 (RevenueCat 2026, 115,000 apps).
“How long should my free trial be?”
14 days on the annual plan won Headspace's A/B test. 17 to 32 day trials convert 42.5% vs 25.5% for 4 days or fewer (RevenueCat 2026).
“Weekly, monthly, or annual, and at what price?”
Structure beats price. Trial-structure changes drove a 59.6% LTV uplift. Gate the trial to annual and the first charge is $60, not $9.
“How many screens, and in what order?”
Run the six jobs of onboarding, then a 3-screen trust sequence before the paywall. It is how Cali ($2-3M/mo) kills bill-shock fear.
“Write my paywall CTA and subtitle.”
Add a 'cancel anytime' subtitle and a step-by-step trial timeline. Blinkist did this and got more sign-ups with fewer complaints.
“Should I require a card to start the trial?”
Outsider did. Sign-ups fell 50%+, but conversion rose 5x, netting 2x the paying customers. Friction that filters intent wins.
