Findings of ILTA\u2019s Tech Survey May Surprise You"},"content":{"rendered":"

At the recent conference of the International Legal Technology Association, the big legal AI vendors CoCounsel, Harvey and Legora had outsized presences, with ginormous booths in the exhibit hall, major-name performers at their parties, and advertising so ubiquitous it even popped up in people\u2019s Uber apps.

At the recent conference of the International Legal Technology Association, the big legal AI vendors CoCounsel, Harvey and Legora had outsized presences, with ginormous booths in the exhibit hall, major-name performers at their parties, and advertising so ubiquitous it even popped up in people\u2019s Uber apps. (See: Have We Reached \u2018Peak Legal Tech?\u2019 Sure Felt That Way At ILTACON this Week<\/a>.)<\/p>\n

So which of those is the preferred choice of law firms? Turns out, the answer is \u201cNone of the above,\u201d at least according to the findings of the just released 2026 technology survey<\/a>.<\/p>\n

The survey spanned over 500 law firms \u2014 all ILTA members \u2014 from small boutiques to global giants, representing a dozen countries and 140,000 lawyers.<\/p>\n

\"\"<\/a><\/p>\n

Of them, the vast majority, 94%, say they are using or exploring generative AI tools, up from 80% last year.<\/p>\n

But when ILTA asked the firms which tool they are using or exploring, the leader by a wide margin was Microsoft 365 Copilot, used by 76% of firms.<\/p>\n

Second place was effectively a three-way tie between two of the leading legal AI products, Thomson Reuters CoCounsel (44%) and Harvey (43%), and one non-legal general AI product, Anthropic\u2019s Claude (44%).<\/p>\n

Legora came in much lower in the results, at 16%, behind products such as Lexis+AI (26%), ChatGPT Enterprise (22%), iManage (22%) and Litera One (17%).<\/p>\n

Breaking that down by firm size shows interesting patterns. Among firms of fewer than 50 lawyers, Copilot retains its top position (59%), followed again by Claude (42%) and CoCounsel (40%), but Harvey drops to 22% and Legora to 6%.<\/p>\n

At the other end of the size spectrum, among firms of 700 or more lawyers, the gap narrows between Copilot and Harvey, with Copilot seeing usage among 88% of firms and Harvey among 84%. But even among those large firms, Claude still gets 64% of usage, ahead of Legora (47%) and CoCounsel (43%).<\/p>\n

Deployment vs. Piloting<\/h3>\n

It is one thing for a firm to say it is using one or more of these AI products, but it is another thing entirely to consider where these firms are in their AI deployment. Here again, the survey offers some revealing data.<\/p>\n

\"\"<\/a><\/p>\n

Only two AI products in the survey have been fully deployed by at least half of respondent firms\u2019 lawyers: Microsoft Copilot, with 52% of firms reporting full deployment among lawyers, and Westlaw Advantage, with 50% of firms reporting full deployment.<\/p>\n

However, here is where the survey results get a bit confusing, as the Copilot that leads in deployment is not Microsoft 365 Copilot, which is a paid product, but, as the survey puts it, \u201cMicrosoft Copilot (formerly Bing Chat),\u201d which would appear to be the free version included in Windows. But the survey also provides results for \u201cMicrosoft Copilot for Windows.\u201d<\/p>\n

Microsoft\u2019s own website lists three versions with different names<\/a> than those used in the survey: Copilot Chat, Microsoft 365 Copilot (Basic) and Microsoft 365 Copilot (Premium).<\/p>\n

Setting aside that discrepancy, the more interesting findings may be those relating to which products firms are currently testing or piloting. There, the two top products are both from iManage, and only nine products were listed by more than half of firms:<\/p>\n
