What AI tells buyers about SaaS prices: a 17-company test
We asked ChatGPT, Claude and Google AI Mode what 17 SaaS products cost, then checked every answer against the official pricing page. AI mostly gets it right, but not when plans change.

answers cited the company's own pricing page
More buyers now ask an AI assistant "how much does X cost?" before they open a pricing page. If the answer is wrong, the buyer may never find out, and neither will you.
On Oct 23, 2026, we asked three AI engines the same question about 17 SaaS products: "How much does X cost? List each plan and its monthly price, and cite your sources." Then we compared every answer with the product's official pricing page.
How each engine did
Fully correct answers, out of 17 questions each:
- Claude: 16 of 17. One minor error, no wrong prices.
- ChatGPT: 13 of 17. Two wrong prices and two minor errors.
- Google AI Mode: 8 of 17. For 7 products it showed only a list of links and no AI answer. Of the 10 answers it gave, 1 had a wrong price and 1 a minor error.
The good news: AI with web search is better at prices than most founders fear. Cursor changed its plans 11 days before our test, and all three engines already had the new prices.
Four ways AI gets prices wrong
Renamed or retired plans
beehiiv moved to Free, Lite and Pro on Oct 1, 2026. ChatGPT still described the old Launch, Scale and Max plans, with their old prices. Google quoted Simple Analytics' retired Starter and Business plans, taken from third-party sites.
Example: ChatGPT listed beehiiv's Scale plan at $49/month. That plan no longer exists.
Monthly vs yearly billing
ChatGPT gave Kit's yearly rates, $33 and $66, as the monthly price. Paying monthly costs $39 and $79. It made the same slip in a table for Turso, though a note under the table corrected it. Many pricing pages open on the yearly toggle, which makes this an easy mistake. We misread two pages ourselves while building the answer key.
Example: ChatGPT said Kit Creator costs $33/month. Billed monthly, it's $39.
Old review and comparison sites
When an engine skipped the official page, it leaned on review and comparison sites, which is where old prices live. This was rare (the official page was cited in 41 of 44 answers), but it caused one of the worst errors in the test.
Example: Google AI Mode quoted Simple Analytics' retired Starter plan at $19, citing four third-party sites and not Simple Analytics.
Currency and region
ChatGPT showed Simple Analytics in pounds instead of dollars. It gave Kommo's Brazilian prices, because we ran the test from Brazil. That's correct for a Brazilian buyer, but easy to miss when comparing tools.
Your help center is a second pricing page
The engines also found contradictions in the companies' own material. Kommo's knowledge base still lists an old $15 Base price. Kit's Help Center doesn't match its pricing page. Activepieces' pricing page contradicts itself on when Free plan credits reset.
AI reads your help center, docs and blog, not just your pricing page. If those pages disagree, AI may repeat whichever one it finds.
What to do if you sell SaaS
- After any pricing change, ask ChatGPT, Claude and Google what you cost. Ask again a week later.
- Put the billing period right next to every price: "$39/mo, billed monthly".
- Search your help center, docs and blog for old plan names and prices, and update them.
- Ask the top review and comparison sites that list you to refresh their pages.
- Keep retired plans off live pages, or mark them clearly as retired.

How we tested
- Products: 17 SaaS products. 10 changed their pricing in 2025 or 2026; 7 are indie tools with stable pricing.
- Engines: ChatGPT (free, logged in, default mode), Claude with web search, and Google AI Mode. We planned to include Perplexity but dropped it after its sign-up wall blocked anonymous queries.
- Prompt: "How much does X cost? List each plan and its monthly price, and cite your sources." For Carrd and WP Rocket, which bill yearly, we asked for "its price".
- Cited means the product's own pricing page, docs or help center was among the sources.
- Correct means no price in the answer contradicted the official page. A minor error is a wrong currency, a mislabeled row, or a labeled estimate that was off.
Caveats: One prompt and one run per product, from a single location (Brazil), on a small sample. AI answers vary from run to run, so treat these numbers as a snapshot, not a rate. We plan to rerun the test with more products, several runs each, and a US location.
