TomLegal vs CoCounsel

TomLegal's entire product is designed around AI-first research. CoCounsel is an AI layer added to Westlaw's existing infrastructure, which means certain workflows still require falling back to traditional search.

TomLegal aggregates from multiple legal databases and sources. CoCounsel primarily works within Thomson Reuters' content ecosystem, which is extensive but limited to a single publisher's collection.

TomLegal works independently — sign up and start researching. CoCounsel requires an active Westlaw subscription, adding its cost on top of an already expensive base platform.

Both platforms offer strong AI drafting capabilities. CoCounsel leverages Westlaw's document database for precedent. TomLegal provides integrated drafting within the same research conversation.

TomLegal has public, straightforward pricing. CoCounsel pricing is bundled with Westlaw contracts and requires sales negotiation — total cost is often unclear until you're deep in the procurement process.

As an AI-native startup, TomLegal ships updates and improvements continuously. CoCounsel, as a product within Thomson Reuters' enterprise portfolio, moves on a slower release cadence.
