AllSearch is a powerful search tool that helps law firms easily search, review, and find documents. Built on an emerging form of AI known as neural nets, AllSearch identifies the specific concept you’re searching for in a document instead of just keywords, allowing for faster, more accurate document searching. 

Simply input a sentence and AllSearch will conduct a concept-based search to instantly find what you’re looking for—even if there are no matching keywords. AllSearch can be used eDiscovery, Knowledge Management, Litigation Management, and more. Built on powerful BERT technology, AllSearch provides a more sophisticated search across any large database (research or document) than most that are currently available in legal.
