| Which plan to pick | 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. | If you're a sole trader or a household already paying for Microsoft 365, Premium is the easy upgrade. For a business, the $30 add-on only makes sense for the people who live in Excel, Outlook and Teams meetings; give everyone else the free Copilot Chat and a Claude or ChatGPT seat. | 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. |
