Turn the Notion pages your team already writes into a website chatbot that answers with sources instead of guesses, stays in sync automatically, and shows exactly which questions your docs still miss.
Visitors don't search help centers, so support answers the same questions again and again, and generic AI chatbots make answers up. MarketGain answers only from your own Notion docs, says so when it doesn't know, and turns those gaps into a ranked list of what to write next.

PDF Vault
PDF Vault is a done-for-you digital business-in-a-box. Members license ready-to-sell PDFs that come with a hosted sales page, and they keep 100% of their sales. It earns money two ways: one-time license fees plus recurring monthly hosting. Tiered pricing raises the price as licenses sell, so each product earns more as it fills and early buyers move fast. Licenses are capped, and new products launch in weekly drops, so the doors open just once a week. That scarcity creates real urgency.
