The problem

The same questions, every day

Much of a support queue is questions your team has answered before: how to reset a password, where to find an invoice, why the app says it is offline. Each one takes an agent a few minutes, and together they push the hard conversations to the back of the line.

Plenty of customers would rather fix it themselves than wait for a reply, if the answer is easy to find. When it sits in an old email, a PDF or a page search engines never see, they give up and write in.

A customer service knowledge base fixes this at the source: write each answer once, put it where customers look, and keep your team for the questions only people can answer.

How it works

Customer self service software that keeps tickets down

Your brand, on your domain

Make the help center look like your product. Start from a theme in the Template Customizer, then change colors, fonts, layouts and components in the template editor, previewing each change on desktop, tablet and mobile. Add your own CSS and JavaScript when you need more.

Serve it on your own domain with SSL, over a global CDN on every plan, so pages load fast wherever customers are. On Growth and Catalyst, you can also host it in a subfolder of your site, at yoursite.com/docs.

  • Subfolder hosting: available on Growth and Catalyst

Being found

Many customers start at a search engine, so give every article its own SEO title, description and URL, and add redirects so old links keep working. Typo-tolerant search finds the right article even when a word is misspelled.

Once published, your help center serves AI assistants too: llms.txt, one setting for what search engines and AI crawlers may do, and a public, read-only MCP server at https://<your help center>/mcp. On Growth and Catalyst, smart 404s suggest articles for a broken link.

  • SEO title, description and URL, redirects, typo-tolerant search, llms.txt, AI crawler controls, public MCP server: available on every plan
  • Smart 404s: available on Growth and Catalyst
  • Semantic (AI) search: included on Catalyst, an add-on on Bootstrap and Growth

Help where customers are

Customers get stuck inside your product, not on your help center's home page. The AI Widget brings search and your articles to any page of your website or app. When an article does not settle it, customers message your team from the widget's contact form.

FAQ sections put short questions and answers on the pages that raise them, such as pricing or checkout. On Growth and Catalyst, you can embed the whole help center in your product with JavaScript.

Learning what's missing

Readers rate each article and can tell you what was missing, and each article's Feedback tab keeps every rating and comment. The Satisfaction score shows the share of positive ratings, with the articles readers like most and those that need work.

Analytics show what customers read and search for, including searches that found nothing: the articles to write next. Analytics are kept for 14 days on Bootstrap, 60 days on Growth and 365 days on Catalyst, and Catalyst includes advanced analytics.

  • Article ratings and feedback, Satisfaction score, analytics: available on every plan
  • Analytics retention: 14 days on Bootstrap, 60 days on Growth and 365 days on Catalyst
  • Advanced analytics: available on Catalyst

Ticket deflection, at the moment customers ask

Ticket deflection works best just before a customer writes in. As someone types into your help center's contact form, it searches your articles and lists the closest matches under the message box, so the answer can arrive before they press Send.

The AI Widget puts search first too, with its contact form one step away. With AI Answers, customers ask in their own words and get a reply written only from your articles, with links to the ones it used.

  • Article suggestions on the contact form: available on every plan
  • AI Answers: included on Catalyst, an add-on on Bootstrap and Growth

FAQ

Questions support teams ask

How long does setup take?
You can start the day you sign up: pick a theme, write or import articles and preview them, then publish once your plan is activated. If we migrate your content, most help centers are live in under 7 days.
Can I use my own domain?
Yes, on every plan, with SSL. On Growth and Catalyst, you can also serve it from a subfolder, at yoursite.com/docs.
Can customers search with typos?
Yes. Search tolerates typos on every plan, so "pasword reset" still finds the right article. Semantic (AI) search, which matches by meaning, is included on Catalyst and an add-on on Bootstrap and Growth.
Can I put help inside my product?
Yes. The AI Widget adds search, articles and a contact form to any page of your site or app, and FAQ sections add questions and answers, both on every plan. On Growth and Catalyst, you can embed the whole help center with JavaScript.
Can you migrate us?
Yes, free on every plan, monthly or annual: we move your articles, categories and images. You can also import them yourself.
Which plan do I need?
Bootstrap suits one person writing in one language. Growth adds up to 10 team members, more languages, subfolder hosting and JS embedding. Catalyst includes AI Answers, semantic search, advanced analytics and unlimited team members.
