Which plan to pickHermes itself costs nothing. If you already pay for an AI model's API, plug that in. If you'd rather not collect separate keys for models, search and browsing, Nous Portal Plus at $20 a month covers light use. There's also a free Portal tier limited to free models.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.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.
