CorpusIQ is an AI intelligence layer that connects ChatGPT, Claude, and Perplexity to live business data across 37+ sources including QuickBooks, Shopify, Gmail, Google Ads, HubSpot, and more via a unified MCP server. Business owners and operators can ask plain-language questions and receive source-cited answers drawn in real time from their connected tools, with no dashboards or manual exports required. The platform uses read-only OAuth authentication, stores zero customer data, and discards query context immediately after each response. Plans start at $19.95/month with a 30-day free trial and no credit card required.
