Features

What changed. Why it matters. What to do about it.

Other tools show raw diffs and leave you guessing. CheckSite reads the page, understands the context, explains changes in plain language, and tells you what to do next.

Smart Change Summaries

Every notification tells you exactly what changed in plain language. Not <span class="price"> diffs — real explanations like "Enterprise plan price increased from $99 to $129/month."

  • Specific values extracted — prices, dates, quantities, not just "content changed"
  • Context-aware analysis understands what each page is about
  • Available on all plans — free and Pro

competitor.com/pricing

Pro plan price increased from $29/mo to $39/mo

Free trial shortened from 14 days to 7 days. Enterprise plan unchanged.

💡 Recommended Action

Update your pricing comparison page and sales deck — Competitor's Pro plan is now $39/mo (was $29/mo), making your $35/mo plan the cheaper option for the first time.

Action Recommendations

Most monitoring tools stop at "something changed." CheckSite closes the loop — every significant change comes with a specific, actionable recommendation tailored to your monitoring goals.

  • Specific actions, not generic advice — references actual values from the change
  • Tailored to your monitoring goals and the type of site you're tracking
  • Appears in every notification channel — email, Slack, Telegram, Discord, Teams, webhooks
Pro

Change Evidence

Every change summary is backed by the exact text from the page. See the before and after side by side — no more wondering if the analysis is accurate.

  • Exact before/after text excerpts with surrounding context
  • Monospace diff view in emails, dashboard, and all notification channels
  • Verifiable proof — never wonder "did the system get this right?"

Smart Triggers

Define exact conditions on any focus area. Get alerted when a price crosses a threshold, text appears or disappears, or a value changes by a specific amount — regardless of what the AI thinks.

  • Numeric: "alert when price increases above $100K"
  • Text: "alert when status no longer contains 'available'"
  • Crossing semantics — fires only when the value crosses the threshold, not on every check
  • Works alongside AI analysis — triggers can fire even when AI rates a change as low-significance

Intelligent Noise Filtering

Cookie banners, ad rotations, timestamps, session tokens — other tools alert you on all of it. CheckSite understands which changes are meaningful and ignores the rest.

  • Automatically detects and ignores dynamic content (ads, counters, timestamps)
  • Significance scoring — only alerts you when something genuinely changed
  • No more "content changed" alerts that turn out to be nothing

Natural Language Setup

No CSS selectors. No XPath. No regex. Just describe what you want to track in plain English and CheckSite configures everything automatically.

  • Type a description like "watch competitor.com/pricing for price changes"
  • Automatically detects the URL, sets up the right monitoring strategy
  • Works from the dashboard chat or the browser extension
Watch stripe.com/pricing and tell me if they change any plan prices

Got it! I'll set up a monitor for:

URL: stripe.com/pricing

Focus: Plan pricing changes

Frequency: Every 4 hours

Custom monitoring prompt

"Only alert me if the Enterprise plan price changes or if they add a new pricing tier. Ignore changes to testimonials, blog links, or footer content."

New "Startup" tier added at $29/mo — alerted

New customer testimonial added — ignored

Blog post link updated in footer — ignored

Custom Monitoring Prompts

Tell CheckSite exactly what you care about in plain English. Unlike keyword filters, natural language prompts understand intent — "alert me only if the free tier is discontinued" is something no keyword filter can express.

  • Natural language intent — not keyword matching
  • Dramatically reduces false positives on noisy pages
  • Works alongside automatic noise filtering for maximum precision
Pro

Automatic Change Categorization

Every detected change is automatically tagged with a category — pricing, content, technical, legal, product — so you can scan your change history at a glance and focus on what matters to you.

  • Categories appear as badges in notifications and on the dashboard
  • Filter change history by category to spot trends
  • No manual tagging — fully automatic
