Three prices for one HubSpot plan in one night, and nine content platform figures that match no vendor page
Two assistants named six content platforms and quoted seventeen prices. Twelve could be checked against the vendor pages the next day. Three matched, nine matched nothing, and one engine gave two different prices for the same plan inside one answer.
Published by AI Knows Us · Updated 22 October 2026
Asked which content marketing platforms are best right now, ChatGPT and Gemini named six products and quoted seventeen dollar figures between them. We fetched every vendor pricing page the next morning. Twelve of those claims were checkable, three matched the page exactly, and nine matched no figure anywhere on it, including three plan names that one of these vendors no longer has. The remaining five claims, all for one vendor, could not be checked because that vendor's pricing page rendered no price at all to our fetch route. One answer managed to carry two different prices for the same plan twenty lines apart, and a third figure for that same plan came from the other engine. If you are budgeting from an AI answer in this category, the plan name is a better guide than the number beside it.
What was asked, and what came back
One question, put to the ChatGPT and Gemini product surfaces through a data provider on 21 October 2026, at 22:20 and 22:38 UTC.
- ChatGPT ran a live search and returned 75 citations, led by 13 from one SEO vendor, 11 from a calendar product, 10 from one all in one platform, 9 from an AI writing tool and 10 across a publishing tool and its help centre. It named five platforms in order and listed four more in a table.
- Gemini ran no live search and returned zero citations. Its answer also arrived as two complete recommendation lists concatenated inside one response, the first breaking off mid way through its source list and the second starting again with a fresh heading and a different set of five platforms.
- Six products carry a price claim across the two answers. Four of them, the all in one platform, the SEO vendor, the calendar product and the AI writing tool, appear in both.
The twelve checkable claims
Every vendor figure below was read by us on 22 October 2026 and belongs to the URL it was read on rather than to the brand. The machine reading them sits on an Indian IP address, which matters on the two pages that render euros beside dollars.
| Claim, and which engine made it | What the vendor page rendered |
|---|---|
| CoSchedule Starter at 29 dollars a month billed annually, ChatGPT | Matches. coschedule.com/pricing renders 29 USD per month billed annually, 39 a month on monthly billing, one user seat included |
| A CoSchedule Social Calendar plan from 19 dollars per user a month, both engines | No plan of that name exists on the page and no 19 dollar figure appears on it. Its plans are Starter, Professional at 49 annual and Suite from 69 a month, custom |
| Semrush Pro at 139.95, Guru at 249.95 and Business at 499.95, Gemini | None of those three plan names is on semrush.com/pricing or on its SEO and AI search pricing page. Both render Free, SEO at 117.33 a month billed annually instead of 139 monthly, Starter at 165.17 instead of 199, Pro plus at 248.17 instead of 299, and Advanced as custom |
| A Semrush content toolkit from 60 dollars a month, both engines | Not on either Semrush pricing page we read. The only add on rendered is additional users from 45 dollars a month |
| StoryChief at about 85 dollars a month, 79 euros annually, Gemini | The 79 euro monthly rate on annual billing belongs to the Agency plan, per workspace, and the page renders its dollar equivalent as 81. Starter is 49 euros or 59 dollars on annual billing. No plan renders at 85 |
| Jasper Pro at 59 per seat a month annually and 69 monthly, Gemini | Both match. jasper.ai/pricing renders 59 a month per seat billed yearly and 69 billed monthly |
| Sprout Social at 249, 399 and 499 per seat a month, Gemini | Not rendered. sproutsocial.com/pricing shows Essentials at 79 annually or 99 monthly, Standard 199, Professional 299 and Advanced 399, all per seat on annual billing |
The one plan with three prices
For the all in one platform both engines named first, the professional tier was quoted three times on one night. ChatGPT said from 450 dollars a month. Gemini's first list said 500 to 890 a month including onboarding fees, and its second list, inside the same response, said 800 a month billed annually. Its starter tier moved too, from 20 dollars a month in the first list to 15 to 20 per seat in the second.
We could not settle it. hubspot.com/pricing/content returned a document to our fetch route whose pricing block did not render, so none of the three figures could be checked against the vendor that day. That records what we received on that date. For a buyer the practical consequence is the same either way: three figures spanning 450 to 890 dollars a month is not a budget, and the only number worth putting in a plan is the one on a quote.
The stale structured data problem, which is the useful lesson here
One of these vendor pages carries a machine readable pricing block that disagrees with its own visible page. Jasper's page renders Pro at 59 and 69 dollars in text, and its embedded structured data lists a Creator plan and a price valid until date of 31 December 2025. The visible page is current and the markup is a year out.
That matters more than it looks. Structured data is one of the things a crawler reads most reliably, so a pricing block left behind at a rename is a stale number sitting in the most quotable part of the page. Two of the wrong figures in the answers above are old plan names, which is exactly the shape of error a retired structure produces. If you publish prices, the audit is short: open your own pricing markup, check the plan names and the price valid until date against the page a visitor sees, and fix the one that is behind.
How to shortlist content platforms without trusting a quoted price
- Shortlist on the job, then price it. Editorial calendar, SEO research, multichannel publishing, AI drafting and content operations are five different purchases that all appear under one search. Our note on the four jobs content platforms do is the buying guide this page deliberately is not.
- Check the plan name before the figure. Nine of the twelve wrong or unfindable claims here are attached to a plan name that has changed or never existed.
- Price per seat against per workspace. Of these six, two charge per seat, one charges per workspace and one bills a platform fee, so the same headline number produces very different bills for a team of four.
- Open the monthly tab. Every confirmed figure above is an annual billing rate, and the monthly rates we could read ran 17 to 34 per cent higher.
- Watch the currency. Two of these pages render euros and dollars together, and one of the quoted claims converted a euro rate into a dollar figure that is on no part of the page.
What this says about being quoted correctly
The engine that ran a live search and cited 75 pages, most of them belonging to the products it named, made one checkable price claim that survived and one that did not. The engine that ran no search and cited nothing gave nine figures that match no vendor page, including a plan structure one vendor retired. For anyone selling software, the lever is not persuasion. It is whether the current number is readable in text, under the plan name a buyer will type, in the currency they see, with the markup matching the page.
That is the measurement AI Knows Us sells, and it is the half of this picture nobody in the answers above reported. We put buying questions to ChatGPT, Gemini, Perplexity, Claude and Google AI Overviews, record every product named, every price quoted and every source cited, and report them with the date rather than as a score. We sell no content platform and compete with none of the six products here.
Our own rates, verified on 22 October 2026, since this page grades other vendors on published pricing. In the US and the UK the ladder runs SEO Start at 149 dollars a month, Growth 299, Scale 599, SEO Scale 699, Inbound 1,099, Outbound 1,299, Agency 1,299 and Everything 1,799. Outside the US and the UK the first two tiers are 99 and 199, so the floor is a US and UK floor. SEO Start reads 0 questions on 0 engines, which makes Growth at 299 the cheapest plan that reads all five surfaces, and a Claude reading costs 3 credits where the others cost 1.
Where a rival is stronger, by name. tryprofound.com publishes single sign on, SAML and SOC 2 with up to nine answer engines on its enterprise tier. Our own pricing document, 119,203 bytes read the same day, renders no single sign on, no SAML, no SOC 2, no ISO certification, no data processing agreement and no white label, and we read five surfaces rather than nine. It also contradicts itself for multi brand work, listing businesses covered as 1 1 1 1 1 1 10 1 across the plans while the row beneath reads more than one business, no, in every column. Both render, which is the same class of defect this page documents in six other vendors.
The limits of this audit, stated plainly. It is one question per engine on one night, and six vendor pages fetched once from an Indian IP address. One of those pages did not render its prices to us at all, so five claims stay unchecked rather than wrong, and a page that served a blank pricing block on that date may render it correctly today.
Questions buyers ask about content platform prices in AI answers
Why did one answer give two different prices for the same plan
Because that answer was two complete recommendation lists concatenated into one response, written minutes apart from the same model with no live search behind either. The first list said 500 to 890 dollars a month including onboarding and the second said 800 billed annually, for the same tier of the same product. Treat an answer that repeats itself as two readings rather than one, and check both.
Is Semrush Pro really 139.95 a month
On semrush.com/pricing read on 22 October 2026 there is no plan named Pro. The plans rendered are Free, SEO at 117.33 a month billed annually against 139 monthly, Starter at 165.17 against 199, Pro plus at 248.17 against 299, and Advanced as custom. The 139 figure is real and it belongs to a different plan name than the one quoted.
Which content platform price in an AI answer can I rely on
The ones a vendor renders in plain text without a toggle. The two claims that survived every check here are a 29 dollar starter rate and a 59 and 69 dollar per seat pair, both printed as text on the vendor's own page under the plan name used in the answer.
Does an all in one platform cost 450 or 800 a month
Three figures were quoted for that tier on one night and the vendor's own pricing page rendered none of them to us, so the number to work from is the one on your quote, with onboarding, seats and the annual commitment itemised separately. The quoted spread of 450 to 890 is wide enough to change the decision on its own.
How do I check what assistants quote for my own software
Ask the category question a buyer would ask, with no product name in it, on each assistant. Record every product named, every figure quoted and every source listed, then check each figure against your own page and your own pricing markup. Repeat it a week later. The plan names move, and a retired plan name in your structured data will outlive the page it came from.
