List of the Best AI Legal Assistant Software in 2026

Start from the work, not the demo. A plaintiff practice reading thousands of pages of medical records has almost nothing in common with a corporate team marking up credit agreements, and the products reflect that: Supio, EvenUp and Paxton are built around records, chronologies and demands, while Marveri and Centari are built around data rooms and deal precedent. Pick the group first and the vendor second. Next decide whether you want the AI where lawyers already work. Clearbrief, Qanooni, StrongSuit, Newcode and Legora all run as a Microsoft Word add-in, which matters because a redline a lawyer has to copy out of a browser is a redline that gets skipped. Then test citations on your own authority. Ask for a research answer in your jurisdiction and open every source it cites. Alexi, midpage, Paxton and Qanooni all stake their pitch on cited output, so this is a fair test rather than a trick. Finally, settle cost and data terms before the pilot. Only 4 vendors in this category publish a figure: midpage at 100 dollars a month for a professional seat and 25 dollars for a law student, Clearbrief at 300 dollars per user a month, StrongSuit at 249 dollars a month per attorney, and Paxton at 499 dollars per user a month or 2,999 dollars a year. Everyone else quotes, so ask for the rate per seat and the minimum commitment in the first call, and ask where your documents are held while you are there.
