Which eDiscovery platforms let paralegals highlight, comment, and filter by annotations?

Annotation tools are core to day-to-day document review. For paralegals, the ability to mark up documents and then act on those marks is what keeps a large review organized and defensible.

The features that matter most are:

• Highlighting and redaction directly on the document.

• Comments and notes the review team can see and respond to.

• Tags or issue codes that classify documents by relevance, privilege, or topic.

• Filtering and searching the whole set by any tag, comment, or highlight, so you can pull every document coded a certain way in seconds.

Most established platforms - Relativity, Everlaw, Nuix Discover, and AI-native tools like Claira - support these in some form. When comparing them, look at how quickly you can filter by annotation across millions of documents, whether tagging is consistent and auditable, and how easily annotations carry into productions and privilege logs.

Claira adds an AI layer on top of familiar highlight-comment-tag review, suggesting issue codes and surfacing annotated documents automatically. See it in action.
