Choosing a legal AI platform in 2026

Compare against the work you need to do

For persistent legal context across compatible assistants, evaluate Legal Workspace. For building your own legal platform, evaluate the SDK. For professional services, use the Marketplace. When comparing other tools, check their current documentation for jurisdiction coverage, source provenance, integrations, data handling, export and total pricing. These are different buying decisions, not a single universal ranking.

How can different AI assistants work on the same legal matter?

Keep the matter’s background, linked sources, knowledge and saved conclusions in Relex, rather than only in a chat. Authorize each compatible assistant to access the same workspace. Its next session can consult that context instead of asking you to rebuild the background.
