Twenty dollars a month, three subscriptions, one question: what does the money buy? This is the AI tool pricing comparison people ask me for most, and the answer is value, not price, since they all cost about the same. - ChatGPT Plus: buys the platform around the chatbot. The biggest model, custom GPTs, the deepest third-party integrations. You are paying for the ecosystem. - Claude Pro: buys the model itself. The largest context window of the three and, in my opinion, the best writing quality. You are paying for capability. - Gemini Advanced: buys zero friction in Google's world. Workspace integration that just works. You are paying for convenience if you live in Google. The uncomfortable part: the free tiers are good enough that many people need no subscription. Be honest about whether you are paying for capability or for the feeling of having the best one.
