About Uncle Louis
Uncle Louis helps tax teams research faster, draft better, and stay current without stitching together five tools.
We did not start Uncle Louis because the world needed another generic AI tool. We started it because international tax teams still spend too much time searching, cross-checking, rewriting, and monitoring across disconnected systems. The work is complex enough already. The tooling should not make it worse.
So we are building software that fits the way tax teams actually work: source-backed research, structured drafting, current legislation, and a cleaner path from first question to final advice.
