How do I export my bookmarks?
Chrome / Edge: open the bookmark manager, then its menu → Export bookmarks. Firefox: Manage bookmarks → Import and Backup → Export Bookmarks to HTML. Safari: File → Export Browsing Data to File → select Bookmarks. Unzip the download and choose its bookmarks HTML file (older versions offer Export Bookmarks).
Choose the downloaded HTML file here. MainTab JSON exports and Chrome bookmark JSON files also work. No browser extension is required.
Or paste a list of URLs
Your file stays in this tab. No bookmark content is sent to MainTab or an AI provider during analysis. Website availability is not checked.

Your topic landscape
Suggestions use saved folders, titles, and website names. They are local hints, not AI judgments. Click a topic to explore; edit anything below.
Duplicates are reviewed together; their tags and notes are combined. Meaningful query parameters and page anchors are preserved. Your original browser bookmarks are never changed.
Skipped entries

Will this change my browser bookmarks?
No. Analysis and edits affect this preview only. Download an export and import it through your browser’s bookmark manager when you are ready.
Can this tell me which links are broken?
This local tool flags issues such as missing titles, duplicate URLs, and unencrypted HTTP links. It does not visit websites or claim that a link is broken. Some websites block automated checks, require sign-in, or are temporarily unavailable.
What happens when I create an account?
Only after you choose to continue, a temporary draft is kept in this tab’s session storage for up to one hour. After sign-in, you review and explicitly save to your account. You can clear the draft at any time. Export a backup before leaving this tab.
