Save any page as a temporary bookmark with a self-destruct timer. Set an expiry, forget about it - TimeMark cleans up after itself. TimeMark lets you save the page you're on right now — without letting it pile up forever. We all save bookmarks "for later." But later never comes, and the list becomes a graveyard of pages you'll never open. TimeMark flips that: every bookmark carries a self-destruct timer. Set an expiry, forget about it, and TimeMark cleans it up automatically. How it works -- Open a page you want to come back to. -- Pick how long to keep it: 1 hour, 6 hours, a day, a week, a month — or a custom date and time. -- Done. When the timer runs out, the bookmark deletes itself. Nothing to maintain. Why you'll love it -- Works the way your memory does — every bookmark is a "reminder for later," not a permanent record. -- Zero cleanup — expired bookmarks are purged automatically in the background, so your list stays clean without you lifting a finger. -- No duplicates — saving a URL that's already saved updates the existing bookmark instead of cluttering your list. -- Search & manage — find anything instantly, edit titles or expiry on the fly, and clear the whole list in one click. -- Your data stays yours — everything is stored locally in your browser. No accounts, no tracking, no servers, no data collection. -- Dark & light themes — pick the look that fits your setup. Perfect for -- Research: keep a handful of sources for a project, then let them expire when the deadline passes. -- Shopping: park a product page for a few hours or days while you decide. -- Recurring reads: tabs you open weekly don't need to live forever. -- Save it. Set a time. Let TimeMark do the rest.
