Free tools
Free tools for AI visibility.
Free tools for AI visibility: read how Gemini describes your brand, which AI crawlers your robots.txt allows, whether your llms.txt follows the proposed format and what share of voice you have on the mentions you count.
Without an account
What can you check for free, tool by tool?
Each tool answers a precise question about your brand’s presence in AI answers. Three work only on the text or numbers you enter; the Gemini check queries the model for you.
For each of the four free tools, the question it answers, what you need to enter and where the result comes from: in your browser or through a question to Gemini.
| Tool | Which question it answers | What you enter |
|---|---|---|
| Gemini check | How does a Gemini model describe your brand, without web search? | The brand name and the site’s domain. |
| AI crawler check | Which AI crawlers can read a path on your site? | The robots.txt text and, if you want, a path. |
| llms.txt validator | Does your file have the title, sections and links of the proposed format? | The text of the llms.txt file published on the site. |
| Share of voice calculator | How much space does each name take out of the total mentions counted? | The names to compare and the mentions of each. |
Origin of results
Three tools work in your browser, without sending anything.
The crawler check, the llms.txt validator and the share calculator read the text you paste and the numbers you type. The result is produced in the page: no site visited on your behalf, no text sent or stored.
The three steps of the tools that work in the browser: you paste the text or type the numbers, the page applies the rules on your device, you read the result with the parts to fix.
You paste the text
Copy robots.txt or llms.txt from your site, or type names and mentions.
The page reads
The rules run on your device, with no calls to a server.
Read the result
A table or a list says what is allowed, present or missing.
After the check
From the free check to measurement repeated over time.
A free tool takes a snapshot of a file or a count at one moment. The platform repeats the reading: it follows the AI agents that visit the site, checks the pages with the audit and calculates share of voice on the collected answers.
Three free tools set next to the platform feature that continues their reading: from written rules to recorded visits, from the file to the whole site, from manual counts to collected answers.
| Free tool | In the platform | |
|---|---|---|
| AI crawlers | Says what the rules of the pasted robots.txt request. | Shows which AI agents actually requested your pages. |
| llms.txt | Checks the structure of the file you copied. | The audit reads the published file together with the site’s pages. |
| Share of voice | Calculates the shares from the numbers you counted yourself. | Counts the mentions in the answers to the questions in your panel. |
Frequently asked questions
Questions about TrustInsider’s free tools.
The answers explain what you need to use the tools, what happens to the text you paste and when it makes sense to move from the free reading to continuous measurement in the platform.
Do I need an account to use the free tools?
No. The four tools are used from their page without signing up. You need an account when you want to repeat the readings over time, on more questions and more assistants.
What happens to the text I paste?
In the crawler check, the llms.txt validator and the share calculator, the text stays in the page: the rules run in your browser and nothing is sent. The Gemini check, by contrast, sends brand and domain to ask the question.
Do the free tools visit my site?
No. They read only what you paste or type. To read the published site, files and pages included, you need the site audit in the platform.
