| Which plan to pick | 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. | Stay on the free plan. The paid Meta One bundles only raise image and video limits, and Meta doesn't publish the actual numbers, so only pay if you're making a lot of AI visuals for social. | Start free and see how often you hit the Pro search limit. If you research most days, Pro pays for itself in saved tabs. Its 4,000 bonus Computer credits are a one-off and run out after about 30 days, so don't count them as a monthly allowance. Max only makes sense if you're using the Computer agent heavily enough to burn through the credits. |
