Sample output

An example of what this Skill produces. Sample content, shown for illustration.

Change digest — Tuesday (2 of 6 watched pages changed)

1. Competitor pricing page
   Pro plan: $29/mo → $24/mo (annual billing now the default view)
   Team plan: unchanged price, priority support added to the feature list
   Why it matters: their entry price just undercut yours by $5.

2. Platform API terms
   Rate limit note changed: 600 req/min → 1,000 req/min for paid tiers.

Unchanged: 4 pages (no digest noise).

What you get

A watch list of pages with per-page change sensitivity
Before/after diffs written as plain-language summaries
Noise filtering for timestamps, ads, and rotating content
One batched digest instead of a stream of pings

About this Skill

Monitors the web pages you name — competitor pricing, docs, partner terms, status pages — and sends one digest when something meaningful changes: what changed, the before and after, and why it might matter. Cosmetic noise (timestamps, rotating banners) is ignored, and unchanged pages simply never bother you.

Try it

Watch these three competitor pricing pages daily. Digest me only real pricing or plan changes, with before and after.

Good fit

Watching competitor pricing and docs
Tracking partner or platform terms you depend on

Not for

Second-by-second stock or price tickers

FAQ

How is this different from an alert tool?

Alerts fire per event; this batches a period of changes into one readable digest with diffs and context.

What counts as a real change?

Text and structure changes above the sensitivity you set; pure layout or timestamp churn is filtered out.
