Entities

Entities are the people, places, organizations, and topics that matter to you. Instead of just saving pages, you can tag the specific things a page mentions. This turns your archive into a connected knowledge base where related content is linked by the entities it references.

For example, if you archive five articles about different companies, tagging each article with the company name lets you instantly find all articles about that company — even if the company is not mentioned in the article title.

You can tag entities from within the browser extension or the archive viewer. Simply select a word or phrase on the page, choose "Tag as entity," and then select the entity type. If the entity already exists in your library, it will be suggested. Otherwise, a new entity is created automatically.

You can also manage entities directly from the Entities page in your dashboard, where you can rename, merge, or delete entities.

Each entity type has an associated color to help you distinguish them at a glance:

• Person / Organization — tagged in sky blue. People and companies mentioned in archived content.
• Place — tagged in emerald green. Locations, regions, and geographic references.
• Topic — tagged in rose. Subjects, themes, and conceptual tags.
• Other — tagged in stone gray. Anything that does not fit the above categories.

These colors appear as badges next to entity tags throughout the interface, making it easy to scan and identify entity types.

The Entities page in your dashboard provides a complete view of every entity you have tagged. For each entity, you can see how many archives reference it and quickly navigate to those archives. The entity browser is searchable and filterable by entity type.

One of the most powerful features of entities is cross-archive discovery. When you tag the same entity across multiple archives, Backdrop automatically links them together. Visiting an entity page shows you every archive that mentions that entity, creating an interconnected research database from your saved pages.

This works even if the entity name appears differently across pages — you can merge duplicate entities to consolidate related archives.
