| Description | TaxGPT is an AI tax co-pilot built for CPAs, accountants, and tax firms (from solo practitioners to enterprise) that automates tax research, drafts client-ready memos and IRS correspondence, and analyzes returns and tax documents, all with cited answers pulled from the IRC, Treasury Regulations, court cases, and IRS guidance. It goes beyond a chatbot with client-memory profiles, AI 'Cowork' agents that run firm workflows inside existing software, and Agent Andrew, an audit/review tool that flags return errors and missed tax savings. Its main differentiator is built-in hallucination control with every answer cited to authoritative sources, positioned as faster and more accurate than legacy tools like Thomson Reuters and CCH. | Grammarly is the world's leading AI writing assistant with 30+ million daily active users. From grammar to clarity to brand voice, Grammarly helps you communicate with confidence everywhere you write. |
