Intelligence, not noise.

Most monitoring tools tell you something changed. The Witness tells you what it means.

Semantic analysis

AI reads the page like a human. "Prices increased 20% across all tiers" β€” not "42 pixels changed in region 3."

Visual evidence

Before and after screenshots for every detected change. See exactly what the page looked like β€” no ambiguity.

Smart alerts

Get notified on Slack, Discord, Telegram, or email. AI scores every change by significance so you only hear about what matters.

An intelligence briefing,
not a diff report.

Here's what The Witness delivers when a competitor changes their pricing page.

Competitor Pricing

Major pricing restructure across all tiers

The competitor has increased prices by 20–35% across all subscription plans while removing the free tier entirely. Enterprise pricing now starts at $299/mo, up from $199/mo.

  • Starter plan increased from $29/mo to $39/mo (+34%)
  • Professional plan increased from $99/mo to $129/mo (+30%)
  • Free tier replaced with 14-day trial
  • Annual discount reduced from 20% to 15%
