How to Check Your LLM Visibility: Free & Paid Methods

At some point almost every marketing team asks the same question. Does ChatGPT even know we exist? It's a fair thing to wonder, since there's no dashboard built into these tools that tells you where your brand stands the way Google Search Console does for organic search. Checking chatgpt brand visibility takes a bit more effort, but it's entirely possible, whether you're doing it by hand or using a dedicated tool.

This post walks through both the free and paid ways to actually find out.

Why This Isn't as Simple as a Google Search

With traditional search, checking your visibility is straightforward. Type a keyword, see where you land. AI models don't work that way. The same question can produce different answers depending on how it's phrased, which model you're using, and even when you ask it, since these systems update regularly. That means checking your visibility isn't a single lookup, it's closer to an ongoing habit than a one-time search.

Free Method 1: Run Prompts Directly in ChatGPT

The most direct free option is simply asking. Open ChatGPT and run the kind of question a real buyer would type, not just your brand name on its own. Broad category questions, comparison questions, and "best" or "top" style prompts tend to surface the most useful chatgpt brand mentions, since these are the questions where the model actually has to make a judgment call about who to include.

Run the same prompt a few times, since answers can vary slightly between sessions. Note whether you're mentioned at all, where you land if you are, and how accurately the model describes what you do. This gives you a rough, honest read on where you currently stand.

Free Method 2: Check Perplexity for Visible Citations

Perplexity is useful here because it often shows source links directly in its answers, which makes it easier to see whether your content is actually being cited rather than just recalled from general knowledge. Run the same category and comparison questions you tested in ChatGPT, and pay attention to whether your website shows up as an actual linked source, not just a name mentioned in passing.

Free Method 3: Test Gemini and Compare Results

Testing a single model only tells part of the story. Run the same set of prompts in Gemini and compare the results against what you saw in ChatGPT and Perplexity. It's common to see meaningfully different answers across the three, and that gap itself is useful information, since it shows you where your visibility is strongest and where it's weakest across the tools buyers are actually using.

The Real Limits of Doing This Manually

Manual testing works fine for an occasional gut check, but it breaks down quickly once you try to do it consistently. Running the same set of prompts across three models week on week, tracking results over time, and comparing them against competitors is a lot of repetitive work for a marketing team to sustain on top of everything else on their plate.

It also misses a layer that matters. Manual checks tell you whether you showed up on a given day, but they don't easily show you patterns, like whether your share of voice against a specific competitor is improving or slipping over several months. That kind of trend is where the real insight is, and it's hard to build by hand.

Paid Method: Dedicated Visibility Tracking Tools

This is the gap dedicated tools are built to close. Branviz runs this kind of testing automatically across ChatGPT, Gemini, and Perplexity, tracking mentions, citations, position, and sentiment continuously instead of relying on someone manually checking prompts every week. 

For any team that needs to report on this consistently or track it against competitors over time, a dedicated tool removes the repetitive manual work and gives a far more complete picture.

What to Look for When Deciding Between Free and Paid

If you're only curious about a general sense of where you stand, free manual testing across the major models will get you there. If you need to track this on an ongoing basis, compare yourself against named competitors, or report on trends over time, the manual approach stops being practical fairly quickly. This is also where regular tracking becomes more valuable than a single audit, since visibility shifts as models update and competitors change what they're doing too.

Common Mistakes When Checking LLM Visibility

Testing only branded prompts is a frequent one, since it tends to paint a rosier picture than testing the broader category questions buyers actually ask. Checking only once and treating that as a permanent read on your standing is another. Some teams also test only one model, usually ChatGPT, and assume the results generalize, when Gemini and Perplexity often tell a different story. And it's easy to overlook citations entirely, focusing only on whether the brand name appears rather than whether the model is actually treating your content as a source.

Bringing It Together

Checking your chatgpt brand visibility doesn't require a tool to get started, a few well chosen prompts run manually will give you a useful first read. Where it gets harder is doing this consistently, across multiple models, in a way that actually shows trends rather than one-off snapshots. That's the point where a dedicated tool like Branviz starts to make more sense than manual checking, since it turns an occasional curiosity check into something you can actually track and act on over time.
