Website change monitoring your agent can actually reason about.
Pixel-diff monitors page you at 3am because a cookie banner moved. OpenHelm captures structured snapshots, diffs meaning rather than markup, and reports "no meaningful change" honestly. Ask for a competitor brief, a price check, or a brand-mention sweep in plain English.

What it does
The monitoring server turns page-watching into structured facts. check_website captures what a page actually says, headlines, sections, prices and plans, as a snapshot your assistant can store; diff_website fetches the live page and reports meaningful differences against a prior snapshot, each with quoted evidence, and says "no meaningful change" when that is the truth. Around that core sit one-shot competitor briefs (positioning, pricing, launches, hiring signals, all source-cited), structured price/plan extraction, and brand-mention sweeps across the public web.
Every tool is read-only and fails explicitly when a page is unreachable or requires authentication, it never substitutes cached or guessed content. For always-on monitoring on a schedule, with alerts only when something meaningful changes, adopt the Site & Competitor Monitoring strategy in the OpenHelm app; these tools are the one-shot actions.
