Best tool to track ChatGPT mentions: the one surface nobody gates, so the decision moves to cadence, prompt count and what a check costs
All nine vendors we read on 20 October 2026 cover ChatGPT at the cheapest tier they publish a price for. Not one gates it behind an add-on, a model slot you have to spend, or an Enterprise call. So coverage ranks nobody here, and the entry tiers that look alike turn out to differ by a factor of eight on prompts and by a factor of seven on how often they are read.
Published by AI Knows Us · Updated 22 October 2026
Every vendor in this market covers ChatGPT on its cheapest published plan, so the engine list cannot help you choose. We read nine vendors' own pages on 20 October 2026 and there is no add-on, no model slot and no Enterprise gate on this surface anywhere, which is not true of Claude, Gemini, AI Mode or Copilot. What does separate the entry tiers is how many questions you can point at ChatGPT, how often each one is read, and whether the vendor publishes what a single check consumes. On those three the published floors range from 15 prompts to 125, and from weekly to hourly.
The criterion, applied to us as well
Four questions answerable from any of these pages without a sales call: prompt allowance at the cheapest published tier, how often that tier reads the surface, how many seats are included, and whether one check has a stated cost. A vendor that publishes all four ranks above one that publishes two, and we say below where that leaves us.
| Vendor | Prompts at the cheapest published tier | Cadence | Seats | Unit published? |
|---|---|---|---|---|
| Otterly.AI | 15 search prompts | "Daily tracking frequency" | "Unlimited team members" | No per-check unit, but a per-engine add-on price |
| Peec AI | 50 prompts | "Daily tracking frequency" | "Unlimited users" | No. "Monthly AI answers" is "calculated by multiplying tracked prompts by active models and tracking frequency" |
| Scrunch | 125 unique prompts, 5,000 responses a month | Not stated per tier | 5 user licences | Responses per month, which is the closest thing to a unit on the page |
| Rankscale | Unlimited search terms, "execution is limited only by your available credits" | "Hourly to monthly" | "Team workspaces (unlimited seats)" | Yes. 0.25 credits per ChatGPT run, with a worked example: "50 prompts x 0.75 credits/run x weekly = 162.5 credits / month" |
| Depra AI | 16 prompt slots, 1,600 successful checks a month | ChatGPT "checked daily" | 1 project, 3 competitors | Yes. "One check is one question asked to one AI engine" |
| Ahrefs Brand Radar | Tiered prompt counts plus an index lookup | "Track prompts daily, weekly, monthly" | Per Ahrefs plan | Yes. "Each prompt uses 1 check per platform, location and update" |
| Semrush | "50 prompts to track daily" on Semrush One Starter; its own FAQ says 25 on the AI Visibility Toolkit | Daily | Per Semrush plan | Prompts per day, by tier |
| Profound | 50 prompts on the free trial | "Daily for 7 days" | Seats unlimited | Credits for its agent features, not for prompt checks |
| AI Knows Us | 30 questions on our lowest AI plan, 100 on the next | Weekly on priority questions, with extra checks on request | 1 full-access login | Yes. "One credit is one buyer question, asked on one AI app, once", with "If a check fails, the credit comes back" |
Where rivals beat us on this surface, which is most of it
This is the surface where we have the least to claim, and the page is more useful for saying so. Otterly, Peec and Depra all read ChatGPT daily on their cheapest published plans. Rankscale will read it hourly. We read weekly by default on priority questions, with extra checks available any time. Otterly, Peec, Rankscale and Profound publish unlimited or near-unlimited seats; we publish one login on every plan. Scrunch's entry tier carries eight times Otterly's prompt allowance. We publish no single sign-on. Any of those is a sound reason to buy somebody else for ChatGPT alone.
Two things we do publish that are hard to find: a unit a buyer can do arithmetic with before signing up, and a stated rule for what happens when a check fails. Of the nine, three publish a per-check unit at all, and one of the three publishes a failure rule.
The arithmetic that actually decides this, because the feature lists will not do it
Rankscale's calculator is the only place in this category where a vendor shows the multiplication, and it is worth copying whoever you buy from. Take your questions, multiply by surfaces, multiply by how often, and only then look at prices.
- Ten real buying questions, ChatGPT only, read weekly, is 40 readings a month. Every vendor on this page handles that at its entry tier.
- The same ten questions across four surfaces, read weekly, is 160. Otterly's 15-prompt entry tier does not carry ten questions on four surfaces if you count a prompt per surface, so check which way each vendor counts.
- Moving from weekly to daily multiplies consumption by about seven. Adding one location doubles it again at any vendor that meters per location, which Ahrefs says it does.
Write that number down in questions, surfaces, places and weeks, then ask each vendor to convert it into its own unit by email. The vendor whose answer matches its own pricing page is the one whose bill will match its quote, and the units genuinely disagree: a check, a credit, a response, a prompt slot and a monthly AI answer are five different things on these nine pages.
So who is best for ChatGPT
- Rankscale on the stated criterion, because it publishes all four answers: unlimited search terms, hourly to monthly scheduling, unlimited seats, and a per-run credit weight with worked arithmetic.
- Peec AI for the cleanest entry tier if three surfaces are enough: 50 prompts, daily, unlimited users, one project.
- Scrunch if a wide prompt set is the point, since 125 unique prompts and 5,000 responses a month is the largest published entry allowance here.
- Otterly.AI if you want the lowest published entry point and will live with 15 prompts, which is enough for one product in one market.
- Depra AI if you sell in India, since its ladder is published in rupees with GST invoicing and a copyable plain-text plan summary.
- Ahrefs Brand Radar if you already own Ahrefs, for the clearest metering rule in the trade and an index lookup that needs no setup.
- AI Knows Us if the unit and the failure rule matter more to you than cadence, and we are behind the first four on cadence and seats.
- Profound for a free seven days of ChatGPT data at 50 prompts daily, after which the route is a demo.
One of those two sells you a plan off the page and the other sells you a conversation, and that difference is worked through here, on one of 147 live pages of ours in this category with no durable inbound link, counted across 2,050 stored bodies.
Questions about tracking ChatGPT specifically
Why does every vendor cover ChatGPT when half of them gate Claude or Gemini?
Because it is the surface buyers ask about first, and because the collection route is the cheapest to run. Rankscale's own calculator sorts its list into GUI engines and API engines and prices a ChatGPT run at its lowest weight, 0.25 credits, the same as Gemini, Perplexity and AI Mode, with Claude at 2. A surface that costs a vendor little to read ends up on every tier.
How many prompts do I actually need on ChatGPT?
Start with the questions a buyer types before choosing, not the keywords you rank for. For one product in one market that is usually between five and fifteen, which fits every entry tier here. The count grows with markets and languages rather than with ambition, so a second country is the thing that doubles it.
Does checking more often make the number more accurate?
It makes the trend line usable sooner, which is a different benefit. Two readings a day of the same question return two slightly different answers, so the extra frequency buys you a faster read on change rather than a truer single figure. Daily is worth paying for when you are trying to prove that something you published moved an answer; weekly is enough for watching a competitor.
Do I need the vendor's suggested prompts or my own?
Your own, with suggestions as a source of ideas. Peec publishes a 1 to 5 relative demand score on each suggested prompt and Ahrefs draws from a very large prompt index, both of which are useful for finding questions you had not thought of. Freeze the set you choose, because editing a prompt breaks the trend line you are building, and ask any vendor in writing whether an edit resets history.
Can I measure ChatGPT without buying anything?
Yes. Ask your five real buying questions with your brand name absent, record every name and every source the answer gives, and repeat on the same weekday each month. Our own free scan asks 5 buyer questions on 2 AI apps and needs no account; our paid plans that check AI apps read all five, including this one. A paid tool earns its place when the repetition, the competitor columns and the stored answer text stop fitting in a spreadsheet.
Which ChatGPT is a vendor reading?
Ask, because the honest answers differ. Depra publishes that it reads consumer web interfaces for ChatGPT. Rankscale names specific model versions on its API side. Our own method uses a third-party data provider for ChatGPT and Gemini. A reading of the consumer product and a call to a model endpoint are both measurements, of two slightly different things, and only the first is what your buyer sees.
The comparison nobody will hand you
Because ChatGPT is on every plan, the engine column in every vendor comparison is a tie, and a tie is where buyers stop reading. The columns that are not tied are the ones above: 15 prompts against 125, weekly against hourly, one login against unlimited, and five different units for one check. Pick the three real buying questions your ChatGPT answer has to get right, ask them yourself this afternoon, then ask each vendor what it costs to read exactly those three, in exactly your market, once a week for a year. Four of the nine can answer that from their own published page, and the ones that can are the ones to start with.
