Bookly

AI summaries that make every bookmark searchable

Automatic AI summaries

Every page you bookmark receives an AI-generated summary saved next to the link, regardless of which folder it lands in.

Natural-language search

Open the popup, type a free-form query and find saved pages by what they were about rather than their exact title.

Works with your existing bookmarks

Bookly layers onto Chrome's native bookmarking so you keep your current habits and folders instead of rebuilding a library.

Lightweight footprint

The extension is roughly 200 KiB, keeps out of the way and runs quietly in the background as you browse.

Strengths & Pros

+Zero-friction setup: it uses Chrome's own bookmarking flow
+Summaries make saved pages findable by meaning, not just titles
+Free to install with a very small extension footprint

Limitations

–Handles bookmarks only — it is not a full knowledge base with notes or sharing
