| Which plan to pick | Use it free. The side panel is what most business owners will actually use, and it's free in Australia. Only pay for AI Pro if you're in the US or India and want auto browse, or you want Gemini's better models anyway. Nobody needs Ultra for the browser. | Hermes 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. | Use it free: the sidebar assistant alone is worth having, and most people never need more. Pro makes sense if you want Perplexity's research tools anyway, but don't buy it just for the browser agent, since Pro's credits are a one-off bundle. Nobody needs Max just for the browser. |
