Frequently asked questions
How does this detect a competitor's technology changes?
Paste the competitor URL and the tool checks the page for shifts in how the site is built, such as new scripts, a changed framework, or a swapped checkout or chat provider. The AI compares each check against the last one and only flags a genuine stack change, so cosmetic edits never trigger an alert.
Will I get spammed every time the page changes slightly?
No. The AI relevance filter reads each change and decides whether it reflects a real technology shift or just routine content and layout tweaks. Minor copy edits, ad rotations, and cookie banners are ignored, so you only get notified when the underlying stack actually moves.
How fast will I know when they add a new tool?
You choose the pace. Instant alerts reach you as soon as a meaningful change is confirmed, which suits time-sensitive competitive tracking. Or pick a daily or weekly digest to receive a rolled-up summary of stack changes on your schedule. It is free to start and takes about a minute to set up.
