Compose

Compose was Casetext’s AI-assisted litigation-brief drafting module, launched as a workflow that let litigators assemble a first draft motion from suggested arguments and authorities. The historical product matters because it was an early, influential brief-drafting tool: LawSites covered Casetext’s own 2020 study claiming 76% faster drafting after only a four-minute introduction, and Thomson Reuters officially acquired Casetext for $650 million in cash on August 17, 2023. But in March 2026 this should not be treated as a live standalone vendor entry. Current official Thomson Reuters product pages point to CoCounsel, Compose has no current independent web footprint beyond stale directory and marketplace references, and the strongest discontinuation signals are secondary sources and shutdown chatter rather than a clean primary-source Compose retirement notice. The honest editorial position is historical capability, now rolled into Thomson Reuters’ broader AI legal stack, not an active product buyers can independently evaluate.
