Windsor.ai vs Supermetrics vs Funnel for AI agents

Windsor.ai, Supermetrics and Funnel move marketing data into sheets, BI tools and warehouses, and each now offers an MCP server for AI tools. Here is what each one's own pages say, how a data connector differs from an AI growth agent, and when to keep a connector and add Cogny.

Every fact about a competitor below comes from that company's own public pages, linked, as of 2026-10-15. Prices and plans change; check the linked page before you buy.

Which is best for feeding marketing data to an AI agent?

It depends on what the agent should do. All three now connect to AI tools over MCP. Windsor.ai includes its MCP server on every plan, including a free one. Funnel's MCP is read-only and builds on its modelled, cross-channel data. Supermetrics' MCP server needs an API-enabled subscription and can also create or modify campaigns. If the agent should also ship a change and get a verdict on it, add Cogny.

What is the difference between a data connector and an AI growth agent?

A data connector copies marketing data from ad platforms and analytics into a destination: a spreadsheet, a BI tool, a warehouse, or now an AI chat. An AI growth agent works on the live tools: it reads the data, proposes one change, makes it after you approve, and checks the result. Cogny is the second kind. It connects your AI to the tools in your stack over MCP (every integration and tool) and closes each change as worked, partial, didn't work or inconclusive.

What are the best Improvado alternatives?

For moving data into a warehouse or BI tool, Windsor.ai, Supermetrics and Funnel are the usual alternatives to Improvado, and each publishes its pricing (Funnel as "starts from"). Improvado also offers an MCP server for AI agents (Improvado docs, as of 2026-10-15). If what you want from AI is changes in the ad accounts with a measured verdict, rather than a governed copy of the data, Cogny is the alternative to look at.

When should you keep a connector and add Cogny?

Keep a connector when you need governed history in a warehouse, a BI dashboard many people read, or a data model finance relies on. Add Cogny when you want your AI to act on the live accounts: change a budget, add negatives, fix a title, then see whether it worked. The two don't compete for the same job. Cogny Cloud also includes a BigQuery warehouse, if you would rather keep one tool.

Choose Windsor.ai if you want a low-cost connector with many destinations, from Google Sheets and BigQuery to AI chats, and a free plan to start.
Choose Supermetrics if your team already reports in Looker Studio or Google Sheets and you want those reports and an AI connection from the same vendor.
Choose Funnel if you need modelled, cross-channel data that many people and tools read the same way, and read-only AI access on top of it.
Choose Cogny if you want your AI to make the change, not only read the numbers, and to know afterwards whether it worked.
Use a connector and Cogny together if you want governed reporting and a loop that ships and measures changes.

Frequently asked questions

Do I need a data warehouse to use AI with marketing data?

No. An AI connected over MCP can query the live platforms directly. A warehouse helps when you need long history, many people reading the same numbers, or joins that the platforms' APIs don't offer.

Does Cogny replace Windsor.ai, Supermetrics or Funnel?

Not for warehouse or BI reporting. Cogny is built to act on your tools and measure the result. Cloud includes a BigQuery warehouse if you want one in the same place.

Who approves a change Cogny makes from my AI?

Your AI client asks before each write. Cogny does not hold the write for a second approval, but logs every write with who authorised it, and any tool can be blocked.

What does Cogny cost?

Free is $0 with 15 MCP calls a month and 50 one-time chat credits, no card. Solo is $9 a month with MCP unmetered under fair use. Cogny AI is $18 (150 credits a month), Cogny Pro $90 (1,500), and Cloud $499 (5,000) for teams.
