| Which plan to pick | Pro is enough to see what it can do for you. Browser tasks use your limits faster than chat, so if you hand it real work every day you'll likely need Max. Teams should use the Team plan so an admin can control which sites Claude can use. | 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. |
