The best AI visibility tools under $100 a month
Five of the tools we looked at start under $100 a month. What you get for that varies a lot, so compare the workload and not only the price.
Disclosure: IndexHalo publishes this guide and sells one of the tools listed. Every fact about another company comes from its own website, read on 3 November 2026. Vendors change their pages and show different currencies by location, so check the current price before you buy.
What matters for budgets under $100 a month
- Questions covered. Entry plans range from 15 to 150 tracked prompts.
- AI sources included. Low entry prices often cover fewer sources, or sell others as add-ons.
- Billing terms. Check whether the figure requires annual billing.

How to choose
The units differ, so a headline price says little until you turn it into your own workload. These four questions usually settle it.
- How often do you actually need to measure? Daily tracking is sold by the prompt, and it suits teams that act on daily changes. Most teams review monthly, which needs far fewer runs.
- Which AI sources do your buyers use? Several plans include only some sources and sell others as add-ons. Check the sources before you compare prices.
- What do you have to hand over? If you report to clients or colleagues, try producing a real report during the trial, and check that you can inspect each original answer behind a number.
- Do you already pay for an SEO suite? If your team already works in Semrush or Ahrefs, their add-ons may be enough. A dedicated tool may go further on evidence and reporting.
Whichever you pick, run a small test first: ten real buyer questions, in one market, on the sources you care about. Our guide on how to choose a GEO tool and on measuring AI visibility go deeper.
