Sometimes saves you three clicks!

A Firefox browser extension that automatically puts new bookmarks in the best matching folder.

• Smart: Uses embeddings to compare bookmark contents, titles, and paths
• Fast: Processes new bookmarks near-instantly
• Private: ML runs in your browser using Transformers.js

When you bookmark a page, the extension extracts clean text content using Mozilla Readability. It then calculates furiously fast potion static embeddings with Transformers.js The embeddings are stored locally in browser storage, keyed by bookmark/folder ID for fast retrieval. When you create a new bookmark, its content is compared against existing folder and bookmark embeddings using cosine similarity. Finally, the new bookmark is automatically moved to the best matching folder.
