Free tools for AI assistant traffic
Three small tools that run in your browser. They fetch nothing, store nothing and need no account.

How the tools work
All three tools run as JavaScript in your browser. The hostname list is part of the page, so nothing you type is sent anywhere, and the tools never open the address you paste. They work from the referrer list, which carries a source and a date for every row.
Each tool is a first step. To use the filters in your analytics, read the guide for your tool: GA4, Plausible, Matomo or PostHog. If your numbers fell in October 2026, start with the incident page.
