How we chose
We looked at tools whose main job is measuring how AI assistants mention brands, and compared them on the things a buyer has to decide on: which AI engines are tracked on the plan you can afford, what you can do for free, the first paid price, and who the tool is built for. We read each vendor's pricing page rather than relying on review sites, because plans in this category change month to month.

How to choose an LLM visibility tool
- Which assistants do your buyers use? Make sure those engines are on the plan you'll actually buy, not just the enterprise one.
- How many prompts do you need? 15 to 25 covers one product; agencies and multi-product brands need hundreds.
- How often? Weekly is enough for most products. Daily data matters for large brands and active campaigns.
- Do you need sources? Citation tracking shows which pages the assistants used, which is what tells you what to fix.
- Reports, API or seats? Agencies need client reports and an API; teams want unlimited seats.
- Start free. Run a free check for a few weeks before committing to a monthly plan.
