Plumbline reads every page you publish and checks each price, limit and promise against the system it came from. When the two disagree, you get the page, the sentence and the fix.
Free for one site up to 200 pages. No card.
Plans start at $12 per seat with a 14-day trial, and every plan includes 40+ integrations out of the box.
Single sign-on is included on every plan, with SAML and SCIM for larger teams.
Plumbline reads plan prices, seat limits and trial lengths from Billing. It never writes back.
14 claims on this page. 13 match their source and one has drifted since the last check.
Checks run every night at 02:00 and each time someone publishes. One page takes about 20 seconds.

Product
Your site says hundreds of things that are true today. Plumbline notices the day one of them stops being true.
Plumbline crawls your marketing site, help center and in-app strings, then lists every factual claim it finds. A 5,000-page site takes about four minutes.
Plans start at $12 per seat with a 14-day trial.
Every plan includes 40+ integrations and EU hosting.
Link billing, your product database, feature flags or a plain spreadsheet. 24 connectors, all read-only, and nothing stored beyond the values it checks.
Each mismatch shows the page, the exact sentence, the value in the source and when that value changed.
Accept a suggested edit and it opens as a draft in your CMS. Nothing goes live until a person approves it.
Checks run when someone hits publish, on a nightly schedule, or both. One page takes about 20 seconds.
Setup
Start with billing, where most drift lives. Access is read-only and you can revoke it in one click.
Paste the URL or connect the CMS. Plumbline finds your help center and its articles by itself.
The first check lists every claim it could match and every one that has drifted from its source.
Customers
“We moved our trial from 14 to 30 days and missed nine pages. Plumbline found all nine before standup.”
“Our help center has 1,100 articles. I used to audit a tenth of them each quarter. Now I read one inbox.”
“The first check found a refund window on our terms page that legal had changed back in March.”
“Pricing said 10 seats and the app allowed 12 for six weeks. The first nightly check caught it.”
“When legal edits a clause I get every page that repeats it. That used to take a week of searching.”
“We publish in 11 languages. It found a German FAQ still quoting last year's refund window.”
Questions
A person reads every message, usually within a few hours.
Write to a personAny sentence that states a fact your systems also hold: a price, a plan limit, a trial length, a feature name, a supported region, a refund window. Plumbline ignores opinions and marketing adjectives.
A language model pulls out candidate claims, then plain rules match each one to a source value. The model never decides whether something is true; the comparison is exact.
No. Suggested fixes open as drafts in your CMS, or as a list you copy by hand. Plumbline has read-only access to every source.
Billing systems, Postgres and MySQL, feature-flag services, Google-style spreadsheets, CSV files and any JSON endpoint. The full list of 24 is on the integrations page.
It goes in an “unmatched” list. You can link it to a source, mark it as fine, or leave it.
Yes, from settings, any time. Your reports stay readable for 30 days after.
About four minutes for 5,000 pages. A single page checks in about 20 seconds, so checks on publish finish before the page is shared.
Yes. Plumbline reads the published pages, so it works with any CMS, a static site or plain HTML. Draft fixes need a CMS connection; without one you get a list to copy.
The first check is free and usually finishes before your coffee does.
