About

Short Description :
 Rediscover forgotten bookmarks & Douban records on every new tab, with a smart weighting system.

Detailed Description:
 Collection Miner turns your new tab page into a daily treasure hunt through your own saved bookmarks and Douban media records.

Every time you open a new tab, the extension randomly surfaces 3 items from your browser bookmarks or imported Douban data (books read, wish list, movies seen, watch list). The more you interact with a card — liking, clicking, or disliking — the smarter the weighting becomes, so the content you love rises to the top and the items you dislike fade away.

Key features:

Bookmark Mining: Randomly displays 3 browser bookmarks on every new tab, drawn from your full bookmark library.

Dynamic Weight System: Like a card to increase its future appearance probability; dislike to reduce it. The extension tracks shows, clicks, and ratings to refine what you see over time.

Rarity Tiers: Items earn visual rarity badges based on your interactions — Legendary (gold border), Rare (purple/blue border), Common (white border), or Cursed (for deeply disliked items).

Age Tiers: Cards display a metallic luster based on how long ago they were saved — Gold (5yr+), Purple (3yr+), Blue (2yr+), Green (1yr+), White (new).

Douban Integration: Import your Douban books (read / wish list) and movies (seen / watch list) as JSON, then mine through your reading and watching history the same way you mine bookmarks.

Premium Card Design: Each card features a 3D tilt effect driven by mouse movement, an interactive cursor-following spotlight halo, seamless flip animations, and three premium card-back themes (Royal Classic, Cyber Neon, Celestial Constellation).

Bilingual UI: Switch between Chinese and English interfaces with a single click.

Keyboard Shortcut: Press Enter to refresh the current 3 cards.

Data Backup: Export and import all your data (weights, history, Douban records) as a local JSON file at any time.

Privacy: All data is stored locally on your device. Nothing is collected, transmitted, or shared. See our privacy policy for full details.

To get started, install the extension and open a new tab — your bookmarks will appear immediately. To add Douban data, click a Douban tab and import your JSON file.
