| Which plan to pick | The free plan is now good enough to use properly, so stay on it until the image, voice or research limits annoy you. Plus is the sensible upgrade. Only look at Pro if you run Codex or deep research all day, and read the current tier details first because they keep changing. | 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. | Start free and see how often you hit the Pro search limit. If you research most days, Pro pays for itself in saved tabs. Max only makes sense if you're using the Computer agent heavily enough to burn through the credits. |
