AI agent detection for paywalled media and premium publishers
Your premium content is valuable to people and to AI agents. SynthTrail shows which agents reach your articles and what they open, so you can see whether your paywall holds up against them.

The problem: premium content, free readers
Agents that load pages in a browser can reach whatever the page sends to the browser. If a paywall hides text on screen but the text still sits in the page source, an agent can read it. You need to know which pages are actually reached and in what volume.
What the trail reveals
Each flagged session lists the articles opened, the time spent, scrolling and clicks, with referrer details where available. Sessions that read many premium pieces in minutes stand out.
Check the page, not only the screen
The page scan reads what the browser holds, flagging secrets, tokens and sensitive comments in the source. It does not compare paywalled and unpaywalled versions of your articles, so review how your paywall delivers text on its own.
