How to choose a group
- You want to start this week on a small budget: look at group 1 and use the trials.
- You need procurement, SSO and a custom contract: group 2, or the Enterprise tier of a group 1 tool.
- Your team already lives in Ahrefs or Semrush: try group 3 first; it adds no new login.
- Your bottleneck is producing content: group 4.
- Whatever the group: confirm which engines your plan includes, whether prompts contain your brand name, and whether you can see the original answers behind every number.
For a closer look at three tools that often share a shortlist, see Profound, Peec AI and Otterly: how they differ. For the questions to ask any vendor, see How to choose an AI visibility tool.
What no tool in this category can do
No tool can prove why an AI answer changed, because nobody can run a controlled experiment on an AI engine's output. No tool can see a model's training data. And every tool samples answers that vary from run to run, so small movements can be chance. Ask each vendor how many answers a number rests on and how much it moves by chance alone.
How we checked
We read each vendor's public pricing or product page on 6 October 2026 and did not test the products ourselves. Prices are monthly billing unless stated. Tools we could not verify that day are left out. Corrections: contact@cleraeoai.com. We re-check this page every quarter.
