“I think some of those points are actually misconceptions. The old version was definitely lagging, but the new version is something else. The way it seamlessly pulls data from Westlaw is a key differentiator, and I don't think anyone will ever catch up to that. Perhaps Lexis , but”
“It almost never answers the question, and if it does, it is always wrong.”
“I agree with the advice to do a trial and see what you think. I’m in-house counsel and in the transactional space, but just my personal two cents: (1) CoCounsel, more than other services, feels like it is made by lawyers for lawyers. It is by NO MEANS perfect, but when reviewing ”

“I work at a midsize law firm with close to 120 users. We looked at Harvey, NetDocuments, and co-counsel. Harvey told us they would not be beaten on the price. They are superduper negotiable, that said we ended up going with Microsoft copilot licenses for the time being, It’s not ”
“Harvey and Legora will get crushed in the long term bc they are just wrappers and RAG. Claude is making moves towards this with some of their tooling. Paying $2.5k per user per month is comedy. These groups have to evolve if they think law firms will be 5-6 figures for an LLM wra”
“Earlier this year, my firm signed up for Westlaw Precision and CoCounsel. We were pitched Precision as “best in class” AI legal research that would keep getting better over time. Cool. Love that for us. It’s also about $2,000/month for a four-lawyer firm, which is a very confiden”
