The Ringtail document review platform includes some useful features which distinguish it from Relativity and other competitors in the document review game.
The quick search tool, will easily allow you to run a search through the searchable text of all documents, and all metadata fields and coded fields.
The review dashboard, which an admin can give users access to, includes an estimate of how long it will take to complete a document review.
Ringtail's concept cloud will generate a word map for documents in a case. It can be narrowed to include particular sets of documents, and the more common terms can be excluded.
Clicking on any of the terms will pull up a list of the documents with those terms.
