Two ways to research.
Answers with the code cited
Nomo AI grounds what it can in the Internal Revenue Code, Treasury regulations, IRS notices and revenue procedures. Each answer lists the sections it relies on.
Claude, ChatGPT and Gemini, side by side
Ask once and get three answers, plus a synthesis of where they agree and where they don't. No more wondering which AI is best.
Claude vs ChatGPT vs Gemini for tax research
Each model has strengths, and each one gets tax questions wrong sometimes. Seeing all three together makes disagreements obvious, so you know when to open the code yourself.
Nomo AI runs them under commercial terms that never allow training on your data.
