Which plan to pickStart on Free to see if the writing suits you. Most people who stick with it move to Pro within a month; only go to Max if you hit the Pro limits every day or you're running Claude Code for hours at a time.Stay on Free unless you also want a VPN. Plus is good value if you'd pay for a VPN anyway. Pro is $19.99, the same as ChatGPT Plus or Claude Pro, so only pick it if anonymity matters more to you than features.Start free. If you're putting anything sensitive in or building something people will use, switch to a paid API key so your prompts aren't used for training. Google AI Pro only makes sense if you'd use the Gemini app upgrade too.
