| Which plan to pick | Stay on free. The side panel, tab comparisons and Journeys cover what most business owners need, and they cost nothing. Microsoft 365 Premium is only worth it if you're in the US and already want Office for the household; don't buy it just for the browser agent, which Microsoft still calls experimental. | Pro 100 is the cheapest way in for one person, and the bigger Pro tiers don't give you a better dot, just more room for the work it runs. If you're in the UK or Europe, or you want dots for staff, Business Premium is the only option. Don't upgrade from Plus just to try it until OpenAI publishes the usage terms that apply after the launch month. | It's all free. Sign in with a free Opera account if you want your chats saved and more images; otherwise just download it and click Ask AI. Opera sells a separate VPN Pro, but you don't need it for the AI. |
