Finance AI Chatbot: Best 6 Tools Compared for 2026

ChatGPT, Claude, and Google Gemini work as finance AI chatbots despite not being built specifically for finance. ChatGPT handles calculations and Excel formulas. Claude processes financial documents like 10-Ks. Gemini integrates with Google Sheets for real-time analysis. DeepSeek costs 99% less than ChatGPT Plus. Microsoft Copilot embeds directly into Excel for formula assistance. No dedicated finance chatbot exists in 2026. Financial institutions build internal chatbots, but you cannot access them. Instead, you use general-purpose AI chatbots for finance tasks. This guide compares six chatbots to help you choose which one fits your financial analysis workflow.

Frequently Asked Questions

No, AI chatbots do not provide SEC-regulated investment advice or recommendations to buy or sell securities. They analyze data, calculate metrics, and explain financial concepts. You make investment decisions based on your own judgment. Chatbots explicitly state 'I cannot provide financial advice' when asked for recommendations. Use chatbots for analysis and research, not for final investment decisions.

ChatGPT, Claude, Google Gemini, DeepSeek, Microsoft Copilot, and Perplexity all function as finance AI chatbots despite none being built specifically for finance. Choose based on your primary task: document analysis (Claude), calculations (ChatGPT), Excel integration (Copilot), Google Sheets integration (Gemini), cost efficiency (DeepSeek), or real-time data (Perplexity).
