spotlight vs. traditional annotation tools: what's the difference?

traditional annotation tools take a screenshot of the page and let you draw boxes, arrows, and notes on top of that image. it's intuitive and familiar. the catch is that the annotation lives on a frozen picture — the instant the real page changes, the picture and the live build no longer match, and the feedback starts drifting out of sync.

it anchors to a static image, not the real element. it loses interactivity — no hover, scroll, or responsive states. it goes stale the moment the page updates. and comments pile up as dead images detached from the build.

spotlight takes the opposite approach. instead of screenshotting the page, it attaches your comment to the actual html element via its css/xpath selector, plus the page url. the feedback is tied to the real component, not a snapshot of it, so it survives layout edits and stays anchored as the page evolves.

it anchors to the live element via its selector and url. it works on the real, interactive page — staging, prototype, or production. it stays attached through layout changes instead of going stale. and every comment collects in a shared team dashboard with shareable links.

annotation tools answer “what did the page look like?” spotlight answers “which element is this about, right now?” — and that's the question fixes actually depend on.

if you're marking up a one-off static asset that will never change, an annotation tool is fine. but if you're reviewing live web ui that keeps evolving — which is most product work — anchoring to the element wins, because the feedback stays valid as the build moves.

the short version: traditional annotation captures a moment; spotlight captures a target. one freezes the page, the other points at the element — and pointing is what keeps feedback fast, current, and easy to act on.
