| 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. | Professional is the plan most teams settle on, because Starter's 10 articles a month runs out quickly. Try the 7-day trial on two or three real articles before paying. | 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. |
