Short version: There are really three separate paths here — a paid monitoring vendor, a branded Custom GPT, or checking the data yourself, since a surprising amount of it turns out to be public. I'd actually start with the free option before paying for the first one: Obsurfable's Explorer is a public corpus of real AI observations you can search today, at no cost, before deciding whether a paid vendor's added layer is worth it for your specific situation.
The three paths people usually mean when they ask this
A monitoring vendor. Paid platforms in this category — Profound, Peec AI, and SignalKit are commonly mentioned examples — run a set of prompts against AI systems on your behalf and report back mention frequency, citation patterns, and share of voice against competitors. This is the path most people picture when they say "tool to monitor how we appear."
A branded Custom GPT. This is a genuinely different goal, even though it gets grouped with the first path sometimes. Building your own GPT using OpenAI's Custom GPT builder gives you a controlled, on-brand assistant powered by your own docs and FAQs — useful for customer support or sales, but it doesn't tell you anything about how the default, general-purpose ChatGPT describes your brand to someone who isn't using your custom assistant.
Checking and earning it directly. The slower path: build genuinely authoritative content, get mentioned by sources AI systems already trust, and check your actual results rather than paying a vendor to check them for you (or as a complement to a vendor, not a replacement for the content work either way).
Before paying for a monitoring vendor, check what's already public
Here's the thing that changed how I think about this category: a meaningful chunk of what a monitoring vendor charges a monthly fee for is aggregating information that's fundamentally public. Anyone can open ChatGPT and ask "what are the best project management tools for remote teams" — the answer isn't proprietary, locked, or specially licensed. What a vendor is really selling is the tedious part: running hundreds of these questions consistently, logging every response, extracting every brand mention, and keeping it current as models change.
That's real, legitimate work. It's also work that doesn't have to be paywalled, which is the position Obsurfable has taken — the corpus of recorded prompts and observations is public and searchable for free at explorer.obsurfable.com, no account needed to browse. You can search your own company, search a named competitor, and look at category pages showing who gets recommended and who doesn't, without a subscription in front of any of it.
A solo founder researching their own category can look at the same evidence a well-funded competitive intelligence team would otherwise pay for — that's the actual argument for treating this baseline data as public rather than a paid unlock, and it's worth taking seriously before assuming a subscription is the only way to get a real answer.
What a paid vendor still offers that the free version doesn't
To be fair about this rather than oversell the free option: a paid monitoring vendor typically covers ground a public corpus doesn't.
| Capability | Typical paid vendor | Free public option |
|---|---|---|
| Quick baseline visibility check | Yes | Yes — free AI visibility checker |
| Browse real recorded AI answers by company or category | Sometimes | Yes — the Explorer corpus |
| A custom, private prompt list tracked specifically for you | Yes | Not the same thing |
| Automated ongoing monitoring with alerts on your schedule | Yes | Not currently offered the same way |
| Export to your own analytics or BI stack | Often | Not applicable |
| Cost | Monthly subscription | Free |
If what you actually need is a private, custom-tailored prompt list monitored continuously with alerting built around your specific reporting workflow, that's a real gap the free corpus doesn't close. If what you need is a fast, honest read on where you currently stand and how your category looks in general, the free version covers a lot more of that ground than the pricing pages of most vendors would suggest.
The Custom GPT path is solving a different problem
Worth separating this out clearly, because it gets lumped in with "monitoring" more than it should. A Custom GPT is about controlling the answer a customer gets when they specifically use your assistant — consistent tone, accurate product details, a controlled experience you can point sales and support toward. It tells you nothing about what the general ChatGPT app says about you to someone who never opens your custom assistant, which is usually the actual concern behind "how do we appear in ChatGPT." Both are worth having for different reasons; neither substitutes for the other.
It's also worth considering who actually encounters a Custom GPT in practice. Unless you're actively promoting it to customers and partners, usage tends to stay low compared to the volume of people asking the default ChatGPT app about your category unprompted — which is exactly the traffic a Custom GPT has no influence over.
The content and citation-earning path underneath both
Whichever tool decision you make, the underlying work doesn't change: authoritative, well-structured content, real third-party mentions, and consistent entity information across the web are what actually shape whether AI systems describe you accurately in the first place. A monitoring vendor or the free Explorer both just tell you whether that work is landing — neither one does the work for you. This guide to what answer engine optimization actually involves is a reasonable starting point if that side of things is still unclear, and understanding which domains AI systems already cite most in your category — covered in this report on frequently cited domains — helps set realistic expectations for how much of the authority gap is closeable through your own content versus third-party coverage.
What I'd actually do, in order
Check the free data first. Search your company and two or three competitors on the Explorer, and run the free visibility checker for a fast structured read. That alone tells you whether you're dealing with a real, current gap or a hypothetical one. If what you find justifies ongoing, private, alert-driven tracking beyond what a public corpus offers, that's the point to evaluate a paid vendor seriously, ideally against the specific gap you've already confirmed rather than a general sense that "we should probably monitor this." Build a Custom GPT separately, if at all, based on whether controlling a branded assistant experience is actually a priority — not as a substitute for either of the above. And whatever you decide on tooling, understanding the metrics worth tracking in the first place will make any vendor conversation more focused, since you'll know what you're actually trying to measure before someone's sales team tells you.
FAQ
Do I need to pay for a tool to monitor how my brand appears in ChatGPT? Not necessarily to get started. A meaningful amount of this data is now public and searchable for free — worth checking that first before evaluating a paid vendor's subscription.
What's the difference between a monitoring tool and a Custom GPT? A monitoring tool tells you how the general-purpose ChatGPT app describes your brand to anyone who asks. A Custom GPT is a branded assistant you control, built from your own content — it doesn't reflect what people see when they're not specifically using it.
Is free monitoring data as good as a paid vendor's? For a baseline check and general category visibility, often yes. For a private, custom prompt list tracked continuously with alerts on your own schedule, a paid vendor typically still covers ground the free version doesn't.
Which AI platforms should I actually check? Prioritize whichever your actual customers use for research — ChatGPT is the obvious starting point given its scale, but Perplexity, Gemini, and Claude are all worth at least a spot-check depending on your category.
How do I know if this is even worth investing time in for my company? Run a free baseline check first. If you're already showing up accurately, the priority is lower than if you find you're absent or misrepresented — either way, that's a five-minute way to find out before committing budget to anything.
Will a paid monitoring vendor make my content get cited more? No, not by itself. Monitoring tools measure and report — they don't change what a model retrieves or cites. The content and authority work described above is what actually moves that, regardless of which monitoring approach you pick.
The honest version of "what tool should I use" is: check what's already free before assuming you need to pay for it, and be clear about which specific problem — measurement, brand control, or content authority — you're actually trying to solve, since they're three different things that happen to get sold under the same "AI visibility" label.
