Shelf Zero 作者： 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 can get an AI summary with key takeaways within seconds. Unread links you didn’t get to come back as a short weekly audio digest (Plus), which you can play on the web. 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.

GETTING STARTED

1. Create a free account at app.shelfzero.app (no card needed)

The free plan includes all 25 slots and 15 AI summaries a month. Shelf Zero Plus adds unlimited summaries, the weekly audio digest, AI skills from technical articles, and a waiting room for 100 links with 25 in view.
