CoCounsel Legal alternatives and competitors
The closest alternatives to CoCounsel Legal are Lexis+ with Protégé, Westlaw, Harvey and Legora.
CoCounsel Legal is Thomson Reuters' legal AI product, grounded in Westlaw and Practical Law. It descends from Casetext, which Thomson Reuters acquired in 2023 and no longer sells under its own name. A lawyer describes a matter in plain language and CoCounsel builds a step by step plan, then researches, reasons and drafts with citations and KeyCite flags beside each authority, and it adds Westlaw Brief Builder and tabular review of up to 10,000 documents. It is sold in plans bundled with Westlaw and Practical Law, with prices published for firms of up to 10 attorneys: CoCounsel Legal costs $784 a month for one attorney on a one year plan, and CoCounsel Essentials $360.
The alternatives below differ from CoCounsel Legal in three ways: the legal content the AI reasons from, the buyer it is built for, and whether it can be bought without a research subscription.
