CHANGE DETECTION
Website Change Detection That Actually Works
Most change detection tools drown you in false alerts. Changeflow's AI understands content, filters noise, and only flags changes that matter. Paste a URL, describe what you care about, done.
Trusted by teams that can't afford to miss a change
The problem with most change detection tools
Basic change detection flags every pixel that moves. An ad rotates? Alert. A timestamp updates? Alert. A cookie banner shifts? Alert. You end up ignoring alerts entirely, which defeats the point. Changeflow's AI reads the page like a person would. It understands context, filters noise, and only tells you about changes that actually matter.
- ✓ AI-powered change detection filters out noise automatically
- ✓ Detects content changes, not cosmetic ones
- ✓ Plain English setup. No CSS selectors or XPath
- ✓ Works on sites that block basic monitoring tools
- ✓ Before/after comparison with every detection
- ✓ Check frequency from hourly to daily
Why Changeflow for change detection
Intelligent change detection
Our AI reads pages like a person. It knows the difference between a price change and an ad rotation. You get fewer, better alerts.
Natural language setup
No XPath. No CSS selectors. No regex. Just describe what you care about: 'Detect when the pricing changes' or 'Alert me on new product launches.'
Content-aware detection
Changeflow understands page structure. It knows headers from footers, content from navigation. Detection focuses on what matters.
Full change history
Every detected change is stored with timestamps and before/after snapshots. Build a complete audit trail of how any page evolves over time.
99.9% access rate
Our technology accesses pages that block basic change detection tools. JavaScript-rendered pages, single-page apps, sites with bot protection.
Flexible alerting
Email, Slack, Microsoft Teams, or webhooks. Get change detection alerts where your team already works.
How teams use change detection
Competitive intelligence
Strategy and product teams
Challenge: Competitors update pricing, messaging, and features without announcement. Basic tools generate too much noise to be useful.
Solution: Set up change detection on competitor pages. AI filters cosmetic changes and only alerts on content that matters: pricing, features, positioning.
Outcome: A SaaS company detects a competitor's pricing restructure 48 hours before it's publicly announced, giving them time to adjust positioning.
Compliance monitoring
Legal and compliance teams
Challenge: Regulatory agencies update guidance on static web pages. No RSS, no email lists, no API. Miss a change and you're exposed.
Solution: Run change detection on FDA, SEC, FCA, and state agency pages. Get AI summaries of what changed, when, and what it means for compliance.
Outcome: A pharmaceutical compliance team detects an FDA guidance update within 2 hours of publication, starting their review process immediately.
Documentation monitoring
Engineering and integration teams
Challenge: Third-party APIs change specs without notice. A breaking change in documentation means a production incident.
Solution: Set up change detection on API docs, SDK references, and changelogs. Catch spec changes before they break your integration.
Outcome: An engineering team detects an API deprecation notice 3 weeks before the deadline, avoiding a production outage.
Automated web intelligence
A URL and brief description of what you care about is all you need.
1 Describe what matters
Tell our AI agent what URLs to monitor and a brief description of what updates you want to be told about. No technical setup or manual configuration required.
2 Let our AI agent track the pages
The platform navigates to pages, checks for updates and uses AI to determine the relevance of the changes. Your personalized feed surfaces only what matters.
3 Stay informed
Get clear summaries as soon as changes happen, explaining the updates and why they matter. Timely intelligence delivered straight to your inbox or feed.

What types of changes can Changeflow detect?
Text changes, price changes, new content, removed content, updated links, new documents, policy revisions. Anything visible on a public webpage.

How fast is change detection?
Pages can be checked as often as every hour. Most users detect changes within hours of publication. For time-sensitive monitoring, hourly checks are recommended.
-
Can Changeflow detect changes on JavaScript-rendered pages?
Yes. Our technology renders pages like a real browser, including JavaScript-heavy single-page applications. We detect changes that simpler tools miss entirely.
