Is there a free AI visibility checker?

Yes. Several tools offer free tiers for single-prompt checks, including Am I On AI and Otterly's free trial. For deeper audits, running prompts manually across ChatGPT, Claude, Gemini, and Perplexity costs nothing but time. This guide explains both approaches.

How do I check if my brand appears in ChatGPT?

Open ChatGPT and enter a prompt a customer might use, such as "what are the best tools for [your category]." Review the response for your brand name, your domain in citations, and the context of any mention. Repeat across three to five prompt variations to avoid single-response noise.

Can I track AI visibility over time for free?

Free manual tracking is possible if you document each check in a spreadsheet with the date, prompt, model, and outcome. Free automated tracking requires a tool with a free tier, which typically limits you to single-prompt checks without history. For ongoing tracking, paid tools starting at $29 per month offer scheduling and dashboards.

Which AI models should I check first?

ChatGPT has the largest user base and should be checked first. Perplexity is a strong second because it cites sources explicitly and is increasingly used for research queries. Claude and Gemini matter for technical and developer audiences. For most brands, checking all four weekly provides enough signal to spot changes.

Free AI Visibility Checker: Test How Your Brand Appears in ChatGPT, Claude & Gemini

What an AI Visibility Check Actually Does

AI visibility testing is an assessment method where you submit prompts to different AI models that simulate customer behavior when researching your niche, and then you capture the responses from the models to see if your brand is mentioned, if your sources are quoted, and if the data mentioned is accurate.

You don’t require any paid software to get started. All techniques listed here can be used for ChatGPT, Claude, Gemini, and Perplexity for free. For those who want automation or tracking over time, there are paid tools included in the list below.

The 15-Minute Manual Check

Have you ever checked how visible your AI is? It takes around fifteen minutes to check the AI visibility for one brand through four models.

Step 1: Create Three Prompts

Think of three questions that someone looking to buy something could ask. Write them naturally, without resorting to unnatural, keyword-filled queries.

Sample prompts set for AI Humanizer tool:

"What are the best tools to humanize AI-generated content?"
"How do I make my text undetected by AI detection software?"
"Should I try out [competitor name]? Why?"

Step 2: Test Each Prompt on Four Models

Start separate sessions with ChatGPT, Claude, Gemini, and Perplexity. Input all prompts into each model, recording their answers.

Step 3: Assess the Answers

Analyze how well the model responded to the input:

Visibility: Is there any mention of the brand name?
Backlink: Did it cite your website or any article there as sources?
Tone: Is the context positive, neutral, or negative?
Details: How accurate is the information provided?

Step 4: Re-check Each Prompt Variation

Repeat the test for each prompt on a second day. Large Language Models can produce various responses, so the single one is often misleading.

Once done with twelve combinations (3 prompts * 4 models), you've got yourself a benchmark. Note down its details into a spreadsheet.

Free Automated Tools

Three methods can check AI usage for free without needing a credit card.

Am I On AI

Tests a prompt against ChatGPT, Gemini, Claude, and Perplexity and gives a summary of brand mentions. Forever free with one-off testing capability.

Useful for: Checking AI use quickly after publishing fresh content.

Downside: No past data, scheduling, or multiple prompts.

Otterly.AI Free Trial

A seven-day trial with full access to all features, including scheduled prompts, history tracking, and sentiment analysis. Post-trial, users pay $29 per month on the starter plan.

Useful for: Checking if investing in paid tracking will be worthwhile.

Downside: Limited to a trial period; requires credit card registration.

Perplexity Source Attribution

Perplexity lists every source it uses, making this method not a separate AI detection tool but still relevant for this guide. Category prompts through Perplexity show which domains are most frequently referenced, thereby providing insight into AI presence across the industry.

Useful for: Identifying which competitor websites rank highest within your niche.

Downside: Only covers Perplexity AI detection.

What to Look For in Results

Pattern 1: Absent Brand, Present Domain

The mention does not cite your brand name but includes your domain name. It means the model managed to find a page from your site, but did not include any information about it in its answer. Fixable via improved mention of brands in on-site content.

Pattern 2: Mentioning Your Competitor, Not You

You have better or equal content compared to the competing sites, yet the model mentions a competitor. This situation arises when the competitor has a stronger backlink profile, thicker page, or a more specific text.

Pattern 3: Untrue Statement About Your Product

The model mentions your brand but gives a description of your product that isn't accurate. The issue is most likely caused by old content appearing at the top results for your site's queries. Fixable with updates to old pages.

Pattern 4: Absence of Any Mencions

This problem arises if the category is mentioned, the clients do searches for this category, but no mentioning of your brand can be found. It indicates that there is a content gap. You haven't written authoritative content in the queries customers use.

The Fix That Changes Results Fastest

In my personal experiments with a dozen categories, the one change that got AI visibility moving the fastest wasn’t adding new content. It was rewriting old AI-created content so it sounded like it was written by a person.

LLMs seem to ignore sites where the writing style matches the profile of AI-generated content. This makes sense since the algorithms learned not to cite their own output as part of their training. The bottom line is that if you’ve created AI-generated content on your website, it hurts your citation rate even if the information is correct.

There’s an easy way to solve this problem by rewriting AI-generated pages using this process before leveraging them for AI visibility. For two out of three of the brands I tried this with, the citation rate jumped up 20-40% in Perplexity over six weeks. The information didn’t change; only the wording and vocabulary profile did.

When to Upgrade to Paid Tools

Three indicators point to when free checks are no longer adequate:

You are monitoring more than one brand or group of competitors.
You wish to have automated daily or weekly tracking.
You require history data to link changes in visibility to changes in content.

For most small organizations, paid visibility tools costing $29-$99 per month are appropriate for addressing these requirements. For a single brand baseline check, the process outlined in this article suffices.
