Designed for sophisticated legal teams; source-check process depends on implementation.

Paid legal AI tool.
Enterprise purchase path.
Use with care
Run a same-question source audit before replacing an existing research workflow.
Usually not the first practical choice for a solo replacing an affordable research subscription.
Evaluation checklist
Run the same source audit before switching
Pick three real questions from recent matters. For each tool, record whether the answer cites sources you can open, whether the quoted rule actually appears in the source, and whether the result distinguishes binding authority from persuasive authority.
- Check one case-heavy issue, one statute-heavy issue, and one drafting workflow.
- Export the result and confirm citations remain attached to public or approved sources.
- Keep any unsupported authority in a review queue instead of polishing it into final work.
Why a reviewable source trail is the real decision
Any tool you compare here can produce confident-sounding text. The risk is fabricated authority. In Mata v. Avianca, Inc., No. 22-cv-1461 (S.D.N.Y. June 22, 2023), the court imposed Rule 11 sanctions after a brief cited cases that an AI tool had invented. Whichever product you pick, the practical test is whether every cited authority opens to a public source you can read — not which interface feels smartest.
