EVIDENCE-BEARING CHANGE MONITORING

Know what changed.
Ignore what didn’t matter.

FluxProof watches pages for people and agents, removes presentation noise, and returns cited before-and-after evidence with hashes, significance rules, history, and webhooks.

No account. No payment. No page content is exposed in the free preflight.

THE RECEIPT, NOT THE NOISE

A changed pixel is not a changed fact.

01

Normalize

Scripts, styles, markup, and presentation churn are removed before comparison.

02

Compare

Stable text, watched terms, and magnitude determine the evidence level.

03

Deliver

People read a concise receipt. Agents receive deterministic JSON or a webhook.

EXAMPLE RECEIPT

Pricing changed. Footer churn ignored.

A watched term matched and normalized similarity fell below the configured threshold.

What FluxProof does not claim
A receipt proves that normalized public content changed between two observations. It does not prove why it changed, who caused it, or that the change is legally or commercially important. Your rules decide what deserves action.
