Hi Product Hunt, I built Tab Review Marker after watching a product manager work through a large set of documents, dashboards, and recordings for a decision brief. The information was open, but its review state lived in memory. Important evidence was missed while less relevant sources received too much attention. I wanted the browser itself to show what had happened, without introducing another dashboard. Tab Review Marker adds one of three small badges to the original favicon: ○ To Review ✓ Reviewed ! Needs Attention The marker remains visible in the tab strip while you read. You can add a note, see the marked sources in the current window, and export the review list for ChatGPT, Claude, or Codex. Privacy was a product constraint, not a footer detail. Review data stays in Chrome's local storage. There is no account, backend, analytics service, advertising, or page-content extraction. The extension exports source metadata only when you explicitly ask it to. This is a free product and still an early one. I would especially value feedback on three questions: 1. Are the favicon states recognizable when many tabs are open? 2. Does the marking flow feel immediate enough? 3. Where else would a visible review state help your workflow? Thank you for trying it.
