- Fits if a daily read on ChatGPT, Perplexity, AI Overviews and Copilot is what you need

Look elsewhere if

- Tight if you start on Lite, with 15 prompts, one workspace, no API or MCP, and no extra prompt packs
- Pricey if you outgrow Lite, as Standard is $160 a month yearly and extra prompts are $99 per 100, with 300 at most before Premium at $422
- Watch out: Claude is tracked through its API using the Haiku model, and crawler analytics needs server log files you upload

- Watch out: the full Action Center is Enterprise only, and Growth gets just a limited trial of it
- Too light for more than one market or project, as Starter allows one of each

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
