| Which plan to pick | Start on Pro to see which jobs it handles well for you. If you hand it real work most days you will hit the limits, and Max is the plan that makes it a daily tool. | Start on Premium at $30 a month, which already includes Grok Bot, and only move up if you hit the usage limits. If your team already pays for Cursor's top plans, check whether Grok Bot is included before paying for anything else. Plans changed on 12 October, so check x.ai before you buy. | 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. |
