Sherlok vs. Windsor.ai
- Free forever plan
- No credit card needed
Windsor.ai is an efficient, low-entry-cost no-code connector that moves data from hundreds of sources into BI, spreadsheets, warehouses or LLMs. It transports; it doesn't analyze, recommend or warn. Sherlok delivers exactly the layer Windsor leaves to you: the decision, with proactive alerts. If you want the decision ready instead of one more pipeline to configure, Sherlok is the choice.

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 350+ connectors and Sherlok has 5. Doesn't that decide it?
Depends on the game. If you need 40 sources in a warehouse, go Windsor. If your operation lives on Meta, Google Ads, GA4, spreadsheets and your own database (like most agencies and e-commerces), depth on those 5 beats breadth of 350.
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, Meta Ads, Google Ads, GA4 or your own database, ask up to 30 questions a month and get the answers, with no credit card and no expiry date. Alerts and insights arrive every week; daily cadence and extra workspaces come with the paid plans.
Less reporting. More deciding.
