Which plan to pickUse the free site. The paid data and custom testing are for AI companies and large businesses comparing models at scale.Start 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.
