Frequently Asked Questions

Everything you need to know before getting started

What is ChangeHappens and how does it work?
ChangeHappens is an AI-powered web monitoring tool. You describe what you want to track in plain English — like "Are there any price changes on my competitors' websites?" — and our AI monitors the web daily. You only get notified when something actually changes, not on every check.
Do I need technical knowledge to use it?
No. There is no code, no CSS selectors, no XPath. You just type a natural language prompt like "Any news about OpenAI GPT-5?" and ChangeHappens handles the rest. If you can write a Google search query, you can use ChangeHappens.
What can I monitor with ChangeHappens?
Almost anything publicly available on the web: competitor pricing, product launches, news topics, research papers, job postings, regulatory changes, stock announcements, event ticket availability, and more. The AI understands context, so you can ask broad questions or very specific ones.
How is this different from Google Alerts?
Google Alerts only tracks new pages or news articles. ChangeHappens monitors actual website content — pricing pages, product pages, changelogs — and uses AI to understand if a change is relevant to your question. It also sends you a clear summary of what changed, not just a link.
How often does monitoring happen?
Monitoring runs daily. You receive a digest email with AI-generated summaries of everything that changed. This keeps you informed without notification overload.
Is there a free trial?
Yes — you get a 7-day free trial with no credit card required. You can set up agents, see how monitoring works, and get real results before committing to a paid plan.
What happens after the trial ends?
After 7 days you can choose a plan: Starter (4.99€/mo, up to 5 agents) or Pro (19.99€/mo, up to 30 agents). If you do nothing, your agents are paused — no charges, no surprises.
Can I cancel anytime?
Yes. No long-term contracts. Cancel from your account settings whenever you want. Your data stays accessible until the end of your billing period.
