FAQ

Common questions

What kind of websites can I monitor?
Any publicly accessible website — competitor pricing pages, job boards, news sites, government pages, e-commerce product pages, and more.
How quickly will I be notified of a change?
On the Pro plan, WatchDog checks every hour. On the Agency plan, every 15 minutes. You'll get an email within minutes of a change being detected.
What does the AI summary look like?
Instead of showing you a raw diff, Claude AI reads the change and writes a plain-English sentence like "The pricing page was updated — Pro plan increased from $49 to $69/month."
Can I cancel anytime?
Yes — no contracts, no commitments. Cancel anytime from your dashboard and you won't be charged again.
Do I need technical knowledge to use this?
None at all. Paste a URL, enter your email, and WatchDog handles everything automatically.
