# Relex vs CoCounsel

## What this product is for

CoCounsel Legal combines legal AI assistance with Thomson Reuters legal research and workflows.

[CoCounsel](https://legal.thomsonreuters.com/en/products/cocounsel-legal)

## Why add—or choose—Relex

Relex keeps your matter’s saved knowledge and progress accessible to compatible agents. It is not a replacement claim for Thomson Reuters’ proprietary research corpus or editorial services.

## What to verify before choosing

Check sources and jurisdictions, then test whether conclusions and citations can be preserved in the continuing matter record. Compare research subscriptions separately from workspace and integration costs.

## Benchmark protocol: prove the handover, not the slogan

Reviewed 25 September 2026\. Published by Relex. A documented product-fit comparison, not a measured performance or legal-quality ranking. A listed product is not automatically a supported or approved Relex integration.
