Shelf Zero by PLQ Software

Shelf Zero is a read-it-or-lose-it reading list: your shelf holds 25 links, no more. When it fills up, you read something or let something go. This extension puts the "save" half of that loop one click away.

WHAT IT DOES

• Save the page you're on with one click, or instantly with Cmd+Shift+S (Ctrl+Shift+S on Windows)
• See the page preview and how many free slots you have before you save
• The toolbar badge always shows your shelf count, colored green, amber or red as the shelf fills up
• When the shelf is full, pick a link to swap out without leaving the popup
• Saved by accident? Undo straight from the confirmation screen

WHAT HAPPENS AFTER YOU SAVE

Every saved link gets an AI summary with key takeaways within seconds, so you know whether it deserves your time before you commit to reading. Unread links come back to you as a short daily audio digest you can play on the web, iPhone, Android or Apple TV. Reading a link frees its slot and builds your streak.

WHY A LIMIT

Endless read-later lists become graveyards. A hard 25-slot shelf forces the honest question every save asks: is this worth one of my slots? Saving becomes choosing, and reading actually happens.
