Three questions, one honest fit. All four major AIs are excellent tools — this is about matching one to your life, not ranking winners. Nobody pays us to be here.
1. Where does most of your daily work and life happen?
2. How do you feel about your chats being used to improve AI models?
3. Budget?
Honest limits: this is a fit-finder, not a verdict on quality — all four are capable, and the "best" one changes with the task. Details verified against official pages as of August 2026; menus and policies move, so double-check in the app. We take no money from any AI company.
