| Which plan to pick | Talk to your Thomson Reuters account manager, since price depends on your Westlaw contract. Ask for a trial on real matters and compare the full CoCounsel Legal tier with the cheaper Essentials bundle before you choose. | Start is enough if your team mainly vouches and ticks figures. Accelerate is where the AI agents come in, which is what most teams buying now want. Ask about seat minimums before you commit. | There is one route in: book a demo and get a quote. Ask which modules you actually need, since many teams only need Negotiate to start. |
