dom-cleaner

Hypothesis (draft)

Most intrusive page junk is unambiguously identifiable from the DOM alone. A 0ms heuristic can clear that tier, and an AI classifier should only ever see the ambiguous remainder.

Stack & constraints

• Chrome extension, Manifest V3.
• Tier 1 (0ms fast path): unambiguous ad iframes (doubleclick.net, googlesyndication.com, taboola.com, …) and standard CMP banners (#onetrust-consent-sdk, Cookiebot, Didomi, LGPD/GDPR dialogs).
• Tier 2: zero-shot AI classification via classifier.dev for everything the heuristic can’t decide.

What shipped

• Ad iframes, autoplay video players and cookie consent modals removed without network delay and without layout shift (CLS) — because tier 1 never waits on the network.

Retrospective (draft)

• Splitting the problem into “free decisions” and “paid decisions” is what makes the extension feel instant; the classifier is the fallback, not the product.
