This "waterfall enrichment" approach means if one source doesn't have the information you need, it automatically tries another until it finds what you're looking for.
It offers both free and paid plans based on credit usage. The free version gives you 100 credits monthly to test the platform, while paid plans provide thousands of credits with advanced features like CRM integrations, AI research agents, and automated workflows for scaling your outreach efforts.

The tool works by analyzing the top-ranking pages for your target keyword and breaking down exactly what makes them successful. It looks at things like word count, keyword usage, headings, and content structure. Then it gives you real-time suggestions as you write, telling you which keywords to include, how many images to add, and even how long your article should be.
