AI assistants have become everyday tools for managing money. But which one actually helps with personal finance? I tested ChatGPT (GPT-5), Claude (Opus 4), and Google Gemini (Pro) head-to-head across real financial scenarios to find out.

Quick Verdict
Claude is best for deep financial analysis and document review. ChatGPT wins for broad financial education and budgeting help. Gemini excels at research with real-time data. None replace a human advisor, but all three can save you hours.
