You check ChatGPT and your brand shows up for "best project management tool for freelancers." Great. You feel good about your AI visibility and move on.
What you don't know is that Perplexity recommends your competitor for that same prompt. Gemini doesn't mention either of you. Grok gives a completely different list. And Claude recommends a tool you've never even heard of.
Each LLM has its own view of the world. Checking one and assuming the rest agree is like ranking on Google and assuming you also rank on Bing, DuckDuckGo, and Yahoo. You might. You probably don't.
Five LLMs, five different answers
This isn't theoretical. Run the same prompt across different AI platforms and you'll see wildly different results. There are real reasons for this.
ChatGPT draws on its training data and has the largest user base. It tends to favor well-known brands and sites with strong topical authority. If you've built a solid content presence, ChatGPT is likely where you show up first.
Perplexity actively searches the web and cites sources in real-time. It's closer to a research engine than a chatbot. Perplexity pulls from recent articles, reviews, and directories. If you have fresh content and strong backlinks, Perplexity often picks you up even if ChatGPT doesn't.
Gemini is Google's AI and pulls from Google's index and knowledge graph. If you have good traditional SEO, you might have an edge here. But Gemini's recommendations don't always mirror Google search results. It has its own logic for what it surfaces in conversational responses.
Claude (built by Anthropic) tends to be more cautious and specific in its recommendations. It often provides nuanced answers and may recommend different brands depending on how it interprets the prompt's context.
Grok (from xAI) integrates with real-time data from X (Twitter) and has its own training data mix. Brands with active social presence and community engagement sometimes show up on Grok even when they're invisible elsewhere.
The bottom line: your visibility on one platform tells you nothing about the other four.
The manual tracking nightmare
Before tools like Mentionable, the only way to check your AI visibility was manual testing. Open ChatGPT, type your prompt, screenshot the result. Open Perplexity, same prompt, screenshot. Repeat for Gemini, Claude, Grok.
Do that for 15 prompts and you've spent your entire morning on copy-paste work. Do it weekly and you've lost a full workday every month. Do it across 5 LLMs and you're managing 75 individual checks per cycle.
And screenshots don't show trends. You can't glance at a folder of screenshots and see "my visibility on Perplexity dropped 30% over the last month." You need structure. You need data over time. You need a dashboard.
How Mentionable tracks all five
When you set up tracking in Mentionable, every prompt you select is automatically checked across all 5 LLMs. You don't configure each platform separately. You don't pay extra for additional LLMs. All five are included on every plan, starting at Starter.
Your dashboard shows the results in one unified view. For each prompt, you see which LLMs mention you, which don't, and how that's changed over time. You can filter by individual LLM to see platform-specific patterns, or zoom out to see your overall visibility score across all five.
The tracking happens at regular intervals based on your plan, so you always have fresh data without lifting a finger.
Spotting platform-specific patterns
The real value of multi-LLM tracking shows up when you start noticing patterns.
Maybe you're consistently visible on ChatGPT and Claude but invisible on Perplexity. That tells you something specific: your site authority and content depth are strong (which is what ChatGPT and Claude value), but you might be missing the fresh, citeable content that Perplexity looks for. A few well-placed comparison articles or an updated resource page might fix that gap.
Or maybe you show up on Perplexity and Grok but not on Gemini. That could point to a traditional SEO gap, since Gemini leans on Google's index.
These patterns turn data into action. Instead of vaguely trying to "improve AI visibility," you know exactly where the gap is and can target your efforts.
Who uses which LLM (and why it matters)
Different audiences gravitate toward different AI platforms.
Tech-savvy users and developers tend to use Claude and ChatGPT. Researchers and information-heavy buyers lean toward Perplexity. The general consumer market is split between ChatGPT and Gemini (especially on Android devices where Gemini is built in). Grok captures the X/Twitter-native audience.
If your ideal customer is a startup founder, they're probably using ChatGPT and Claude. If you're targeting small business owners who aren't deep in tech, Gemini might be their first AI experience. If your audience lives on X, Grok matters more than you think.
Knowing where your target customer asks their buying questions helps you prioritize which LLM gaps to close first. Multi-LLM tracking gives you the data to make that call.
What you see in the dashboard
For each tracked prompt, Mentionable shows you:
- Mention status per LLM: a clear view of where you're recommended and where you're not
- Position and context: not just "mentioned" or "not mentioned," but how you appear in the response
- Trend over time: are you gaining visibility on a platform or losing it?
- Competitor presence: who shows up alongside you, or instead of you, on each LLM
This isn't a one-time snapshot. It's a living picture of your AI visibility that updates automatically.
Part of the full workflow
Multi-LLM tracking connects directly to the rest of Mentionable's features. Your automatically generated prompts get tracked across all five platforms. Competitor analysis shows you who's visible where. Email alerts notify you when your status changes on any LLM. And AI Insights (on Pro and Agency plans) use the cross-platform data to generate specific recommendations.
All of it starts with tracking all five LLMs, not just the one you happen to use yourself.
