How it works

Turn a plain-English question into a repeatable market signal.

Sentinel4 combines scheduled web checks with an AI evaluation step. It is designed to tell you when a meaningful condition is met, not every time a page changes.

  1. 1

    Describe the signal

    Write the condition you care about: a pricing change, new product capability, documentation update, or hiring pattern.

  2. 2

    Choose public sources

    Add the competitor pages and other public URLs that should be checked, then choose a schedule from every 30 minutes to quarterly.

  3. 3

    Receive evidence

    When the rule matches, Sentinel4 sends the result through email, SMS, or webhook with source context for review.

What Sentinel4 does well

  • Evaluates a specific business condition
  • Checks multiple public sources on a schedule
  • Keeps source URLs with alert results
  • Supports email, SMS, and webhook delivery

What you should verify

Web pages can be incomplete, delayed, blocked, or ambiguous. Treat every alert as decision support: review the linked source before publishing a claim or making a high-impact decision.
