How to Automatically Tag Your Bookmarks with AI

Tagging is the part of bookmarking everyone agrees is useful and nobody actually does. In the moment you're saving a link, stopping to think up three good tags is friction, so you skip it — and three months later your library is a flat, unsearchable pile.

The fix isn't more discipline. It's letting the tags write themselves.

Why manual tagging fails

Manual tagging asks you to do the organizing work at the worst possible moment: when you're mid-task and just want to save something and move on. It also depends on you being consistent — was it

Automatic tagging removes both problems. The work happens in the background, and the tags stay consistent because they're generated from the page's actual content.

How automatic tagging works in onBookmarks

When you save a link, onBookmarks' AI tagging reads the page and suggests relevant tags and a collection to file it under. You can accept the suggestions with a click, tweak them, or ignore them — but the default path is "save, and it's already organized."

Because the tags come from the content itself, similar pages get similar tags, so searching for a topic surfaces everything about it instead of just the handful you remembered to label.

Tagging your existing pile, too

Automatic tagging isn't only for new saves. If you already have hundreds of untagged bookmarks, you can import them and let onBookmarks suggest tags across the whole library at once — turning a flat list into something you can actually filter and search, without hand-labeling every entry.

Tags plus collections

Tags and collections work best together. Collections are the broad buckets — a project, a client, a course. Tags are the cross-cutting labels —

A note on privacy

Automatic tagging needs to read a page's content to suggest tags, so it applies to your normal bookmarks. Anything you mark for client-side encryption stays private and isn't read — that's the trade-off of zero-knowledge encryption, and you choose which bookmarks are sensitive enough to keep out of it.

Try it

Stop tagging by hand. Create a free account, save a few links, and watch your library organize itself.
