How to decide
- 1Write down the AI engines your buyers actually use, and check each tool covers them on the plan you can afford.
- 2Count the prompts, brands and countries you need now and in a year, and price both tools at that size.
- 3Check whether you need an API or exports for your own reports.
- 4Run a trial with 20 to 50 of your own buyer questions, and compare what each tool shows with what you see when you ask the same questions yourself.
- 5Pick the one that shows you something you can act on fastest.
