The AI Agent Index is an independent directory and comparison resource that helps teams discover AI agents for business tasks. It lists more than 414 agents across eight categories, including sales, customer support, research, marketing, coding, HR, workflow automation, and customer success. Each listing is independently reviewed for capabilities, pricing, and integrations, with verified information intended to help users compare options and find agents suited to their needs.

The directory is free to search and includes category browsing, agent comparisons, alternatives, platform integrations, and tools for matching agents to a team’s requirements. Users can explore connections with services such as Slack, Salesforce, HubSpot, Zapier, Gmail, Microsoft Teams, and GitHub. The Index also provides agent stacks, guides, educational definitions, price and rating updates, and recently verified listings. For developers and AI systems, it offers a public JSON API, an MCP server, structured data, and machine-readable resources designed to support discovery and citation. The site states that its editorial ratings remain independent, including for featured listings that may contain affiliate links.
