Windsor.ai is an affordable no-code connector, with a free plan for 1 source, that moves data from hundreds of sources into BI, spreadsheets, a warehouse or your Claude and ChatGPT. It moves the data; the analysis and the decision stay with you. Sherlok delivers exactly that layer: agents that read your accounts, flag issues without being asked and bring the decision. If you want the decision ready instead of one more pipeline to configure, Sherlok is the pick. Start free, no card.
Read-only connection
The agents read your metrics. Nothing changes in your accounts through Sherlok.
Encryption in transit and at rest
Your data is encrypted on the way and in storage.
Revoke access whenever you want

No card to start
Free is your account diagnosis: 30 questions a month, no card.

- You need sources Sherlok doesn't connect to yet
- You're comfortable configuring pipelines and destinations

Frequently asked questions
Doesn't Windsor + ChatGPT do the same as Sherlok?
Partially. For people who set up MCP and actively query, it works as on-demand analysis. What you can't improvise there: continuous monitoring with proactive alerts, embedded local market context, one-account simplicity, and native-language support. It stays pull-AI: nobody warns you when ROAS drops.
Windsor has hundreds of connectors. Doesn't that decide it?
Depends on the game. If you need 40 sources in a warehouse, go Windsor. Sherlok has 5 native connections in depth (Meta Ads, Google Ads, GA4, Search Console and SQL) plus 1,500+ integrations in the catalog. The difference is what comes after the data: Windsor delivers the data; Sherlok delivers the decision.
I already use Windsor to pipe my data into BigQuery. Is Sherlok still worth it?
It is, once the question stops being 'where is the data' and becomes 'what do I do today'. Windsor can keep feeding your BI; Sherlok watches the accounts and sends you every week what needs attention. Connecting takes minutes and the Free plan asks for no card.
Is the free plan enough to really test it?
It is: you connect two sources, such as Meta Ads, Google Ads, GA4 or Search Console, ask up to 30 questions a month and get the agents' decisions every week, with no credit card and no expiry date. More sources and workspaces come with the paid plans; daily decisions come with Pro.
Less reporting. More deciding.
