| Which plan to pick | There's only one way to pay. Use the $1 trial credit to test the MCP server, then top up $50 and set a daily limit of a dollar or two. Use the cheaper standard queue for bulk jobs and the live mode only when you need an answer now. | The free version is enough for most small businesses because it includes every feature and only caps the crawl at 500 pages. Buy a licence when your site or your clients' sites go past that. The price is listed in pounds with dollar and euro options at checkout. | Start on Starter to see where you stand in AI answers. Growth is the plan for teams who will act on the findings each month, because that is where sentiment and suggested fixes come in. |
