Legal AI pricing is mostly hidden. Here is what vendors publish, what has been reported, and what nobody can confirm.
Most legal AI vendors do not publish prices, the third-party sites that claim to know them often disagree, and some of those sites are run by competitors. Published rates come mainly from broader software makers, such as the Microsoft 365 Copilot Business add-on at $21 per user per month on its pricing page and Clio from $49 per user per month on its pricing page, while CoCounsel’s $292.50 starting price was reported in a February 2026 ABA GPSolo review and Harvey and Legora publish no rate cards. This guide separates published, reported and untraceable numbers, all checked in October 2026, and prices in this market change often.
Which Legal AI Prices Are Published?
The clearest prices come from general software companies that sell legal features on top of a broader product. Microsoft’s Copilot pricing page lists the Microsoft 365 Copilot Business add-on at $21 per user per month on an annual commitment, with a promotional $18 rate for the first year on purchases between July 1 and December 31, 2026. Bundles run $23.50 per user per month for Business Standard with Copilot and $32 for Business Premium with Copilot. Some newer features, such as Cowork, are billed by usage. That matters for legal teams because Microsoft launched Copilot for legal on October 15, describing more than 20 legal skills generally available to Copilot customers, with plugins from Harvey, Legora, iManage and others.
Practice management vendors also publish rates. Clio’s pricing page starts at $49 per user per month and says its AI features are included from the Core plan upward.
Thomson Reuters sells CoCounsel Legal online to new customers through a plans and pricing page with one-, two- and three-year terms, but the actual figures sit behind an interactive configurator rather than a public list. Spellbook’s pricing page says pricing is customized to team size and offers a seven-day free trial. LexisNexis’s law firm store asks buyers to call for Lexis+ with Protégé pricing.
What Do CoCounsel and Harvey Reportedly Cost?
For CoCounsel, the most useful public numbers come from a February 2026 review in the ABA’s GPSolo magazine. The authors reported starting prices of $292.50 a month for CoCounsel Essentials, $415.35 for Westlaw Advantage with CoCounsel Essentials, and $551.85 for CoCounsel Legal. The article discloses that Thomson Reuters sponsors the ABA division that publishes the magazine and that the authors received complimentary access. Treat those figures as reported starting points for small firms, not as what a large firm pays.
Harvey has never published a price list. The most frequently repeated number comes from a 2024 Artificial Lawyer report, which said sources had told it firms were quoted about $1,200 per seat per year, and that a minimum of 100 seats for one year had been demanded on at least one occasion. Harvey did not respond to that report. The figure is more than two years old and predates Harvey’s current product line, its September 2026 funding announcement and its move into agents, so it is a historical data point, not a quote.
How Does Legora Price Its Product?
Legora does not publish prices. What it has published is a change in model: in June 2026 it moved its Agent Pro tier to consumption-based pricing, billed by usage with dashboards and spending controls, while its standard agent remains included at no extra cost. That puts Legora in the same direction as Microsoft, which also bills some agent features by usage.
Per-seat figures for Legora do circulate on comparison sites. Several of those sites are published by competing legal AI vendors, the numbers do not agree with each other, and none we found cites Legora or a named customer. We are not repeating them. If you see a precise Legora seat price online, it is worth asking where it came from.
Why Is Legal AI Pricing So Hard to Find?
Three things keep legal AI pricing opaque. First, enterprise deals are negotiated. Seat counts, contract length, which modules are included and whether research content is bundled can all move the price, and vendors have little reason to publish a rate card that becomes a ceiling.
Second, the pricing unit is changing. Early reporting, like the 2024 Harvey figures, described per-seat licensing. Usage billing for agents, which can run long multistep tasks, is now spreading, and that makes total cost harder to predict in advance. Legora’s announcement pairs usage billing with dashboards and spending controls.
Third, the published consumer-style prices often describe a different product than what a large firm buys. A solo lawyer’s monthly CoCounsel subscription or a $21 Copilot add-on tells you something about the floor of the market. It tells you little about a multiyear platform agreement with a firm of 1,000 lawyers.
The ethics side touches pricing too. The ABA’s Formal Opinion 512 discusses when the cost of a generative AI tool can be passed to clients, treating tools built into ordinary software as overhead and describing per-use third-party tools as a possible expense. How firms recover the cost shapes how much they are willing to pay.
What Should You Watch Next?
Watch whether usage billing spreads from agents to the rest of each platform, which would make monthly bills less predictable for firms that are used to flat seat costs. Watch Microsoft’s legal push, since a capable legal layer inside software firms already license could put pressure on standalone seat prices. And watch for any vendor willing to publish a real rate card. The first large legal AI company to do that would make every comparison in this piece easier, and would put the others under pressure to follow.
