The problem, and the approach

The preponderance of LLM generated content presents the problem: how can I prove that someone has done work to complete a task, or how can I prove that a document I'm reading was written or reviewed by a human?

This website proposes a remedy: obfuscated keylogging. If we transform the actions a user takes (pauses, pastes, other special keys) into a transferrable chunk of data, we can pair that data with the content itself and perform some static analysis on them together to provide confidence that the content was produced via the associated human session.

The internal mechanisms of how the singature and analysis work are omitted here, per the clear objection: someone will figure out how to spoof these signatures. And when they do we can increment the version of the signature or analysis algorithms; this isn't an undefeatable approach, but just as its simple to break a window or pick a front door lock, the presence of the barrier itself denies opportunists.

As of mid-July, 2026, this webpage serves as a playground; there are many simple patterns of inputs which can still defeat the system today. By using the playground you can help provide examples of false positives or negatives.
