Knowledge base and AI answers for software products
The AI help center for your product.
PageTruth answers your customers from your own docs, with a citation for every claim, inside your app, on your site and on your own domain. When the docs don’t cover something, it says so and hands over to your team.
Free plan, no card. Live on your site in about ten minutes.
The problem
Your docs answer the question. Your customers can’t find the answer.
Support teams spend their day pasting links to articles that already exist. The fix is not more docs — it is getting the right sentence from the docs you have to the person asking.
Search finds keywords, not answers
A help-center search for “export” returns twelve articles. The customer opens a ticket instead of reading them.
Knowledge lives in five places
The docs site, a PDF admin guide, the changelog, a Notion page and a support macro. Nobody searches all five.
You never see what was missing
A failed search leaves no trace. You find out what your docs lack one ticket at a time.
One knowledge base, four ways in
Answer customers wherever they ask
Curate the knowledge once in the dashboard. Every surface answers from the same sources, with the same citations and the same tone.
Knowledge base
Everything your product knows, in one index: your docs site, PDFs, Word files, changelog and articles you write in PageTruth.
Learn more →Hosted help center
A search-first help center on help.yourproduct.com, with your logo, your colours and your articles, answering in plain words.
Learn more →In-app help widget
One script tag. A side panel, a popover, a ⌘K search or an inline block — the same answers, wherever your customers are.
Learn more →Answers API
Ask from your own code with a secret key and get the answer and its citations as JSON, for your app, your bot or your support tool.

How it works
From docs to answers in an afternoon
No training runs, no flows to draw, no intents to label. Add what you already have.
Connect your sources
Import your docs site by URL or sitemap, upload PDFs and Word files, or write articles in the editor.
Publish
Turn on the hosted help center, choose a widget layout and paste one script tag into your app or site.
Customers ask
They get an answer in seconds, from your docs only, with the page and section it came from.
Close the gaps
See what was asked that your docs could not answer, and write the article that answers it next time.
The help widget
Four layouts, one script tag
Pick the one that suits the page. Side panel for in-app help, popover for your marketing site, centered search for docs, inline for a Help page.
Side panel. Slides in from the right or left at full height, next to the screen the customer is stuck on. The page stays usable behind it.
Switch layouts from the dashboard at any time. The snippet on your site never changes.
Grounded answers
Every answer shows its source
Citations are not a link list at the bottom. Each claim is tied to the passage that supports it, resolved to a real document and page, so a customer can read on and your team can check it in one click.
- Answers only from the sources you add, never from the open web
- Says “that isn’t in our docs” instead of guessing, then offers your support channel
- Every claim links to the page or section that supports it
- Documents are treated as evidence, never as instructions — injected text in a file cannot take over the assistant
- Each knowledge base has its own isolated search index
Insights
See exactly what your docs are missing
Every question the knowledge base could not answer is grouped, counted and waiting for you, with a button that starts the article.
- Content gaps, ranked by how often they are asked
- Answer volume, resolution rate and ratings over time
- Every conversation, with the sources each answer used
- A weekly digest of new gaps by email
Knowledge
Bring the docs you already have
No migration. PageTruth reads what you have today and keeps it current.
Your docs site
Import one page, a whole sitemap, or keep a URL re-synced daily.
PDF, Word, Markdown
Admin guides, runbooks and specs, including scanned PDFs.
Articles
Write and publish help articles in PageTruth; they are searchable the moment you publish.
Changelog and release notes
Point at your changelog so the help center knows what shipped yesterday.
Examples
See it set up on real-looking products
A project-management app, a payments API, a scheduling tool and a form builder — each with its sources, its settings, its widget and the questions their customers ask.
Predictable costs
You pay for answers, and only the ones that help
AI answers cost real money to produce, so we built the controls in rather than leaving you to discover the bill.
One clear number
Plans include a set number of AI answers a month. The meter is in your dashboard, and we email you at 80% and 100%.
Repeat questions are free
When the same first question is asked again and your content has not changed, the stored answer is served and not counted.
“Not in the docs” is free
If nothing in your knowledge base is relevant, the reply costs no answer — you only pay for questions it can answer.
Caps you control
Set a monthly limit per knowledge base, so a launch-day spike on one product never spends the budget of another.
Only your sites
The widget only answers on domains you allow. Nobody can copy your snippet and spend your answers.
Abuse limits built in
Per-visitor and per-IP rate limits stop scripts and runaway loops before they reach the model.
Pricing
Start free, pay as your customers ask more
Every plan includes the help center, the widget in every layout and page-level citations. Prices in USD.

Questions teams ask
Something else? Email us. A person replies.
Is this a chatbot?
No. A chatbot is a script with a personality. PageTruth is a knowledge base and help center for your product: it answers only from the docs you give it, cites the page every answer came from, and tells you what your docs are missing.
What can it learn from?
Your docs site (by URL or sitemap, re-synced on a schedule), PDF, Word, Markdown and text files, and articles you write in the PageTruth editor. Scanned PDFs work too.
What happens when the answer is not in our docs?
It says so, plainly, and offers the handoff you configure: your support email, a contact form or a link. The question is logged as a content gap so you can write the missing article.
How do I add it to my app?
Paste one script tag into your app or site, then pick the layout in the dashboard: side panel, popover, centered ⌘K search or inline. You can open it from your own Help button with PageTruth.open().
Can I use my own domain?
Yes, on Growth and Scale. Add a CNAME such as help.yourproduct.com and the hosted help center is served there with your branding and no PageTruth badge.
What counts as an answer?
One question that gets an AI-written answer. Repeat questions served from the cache, and replies where nothing in your docs was relevant, do not count. When you run out, the widget offers your support handoff instead, or you can add 500 answers for $20.
Is our content used to train AI models?
No. Your content is used to answer your customers’ questions and nothing else, and our AI providers do not train on it.
Give your customers answers, not a ticket number
Point PageTruth at your docs, publish a help center and drop the widget into your app. The free plan is enough to see it answer your own questions.
