Check a visitor

A browser-side evidence helper for Home Alone (Anomaly). It matches your observation against collected public reports and never invents a probability or hidden rule.

Local resultReported warning

Large night-vision reveal

The size and alien description are community-reported and should be checked against the current scene. This is a public reported signal, not an official guarantee.

Night vision shows an unusually tall, roughly seven-foot alien-like appearance.
How it works

Three inputs, one bounded result

  1. Choose the visitor or a known alias.
  2. Choose the evidence channel you actually checked.
  3. Describe the clue in concrete words.
Privacy

Local by design

The observation is processed in this page and is not submitted to a server. Analytics, if configured, measure page views separately and do not need the clue text.

FAQ

Checker questions

Does the visitor checker send my observations to a server?

No. The checker runs locally in your browser and uses a deterministic copy of the collected evidence map.

Does a reported warning prove a visitor is an anomaly?

No. It means your selected clue matches a public reported signal. Confirm the full scene and current in-game context.
