Knowledge base software is one shelf.
This is the shelf beside it.

Article tools are priced per plan, and per seat on some tiers. This page says what each one is for, in plain words. Then it shows the cheaper shelf next to them: the questions your customers actually asked, answered once. $9 one time on a Forumcat subdomain, or $99 a month for your own domain.

This is not a knowledge base editor. It is a public Q&A archive that sits beside one.

Free for 7 days. No credit card. Live in about five minutes.

The shape of it

Two shelves in one help center

A knowledge base holds the articles your team decided to write. Someone plans them, writes them, and keeps them in order.

A Q&A archive holds the questions your customers actually asked. The order comes from them, not from a content plan.

Most support teams end up wanting both. The articles explain the product. The questions cover the corners no article thought of.

Search

The list of what to write next

Every search on your portal is counted. When a search finds nothing, it lands in a list you can read on the Analytics page.

That list is the honest version of a content plan. It is written by the people you are writing for.

  • Full-text search over every question, open to everyone
  • A log of searches that found nothing
  • Views per question, so you can see which answers carry the load

Side by side

An article, and an answered question

Both are help content. They are made in different ways, and they age in different ways.

The left column describes article tools as a group, not any one vendor. Vendor numbers move, so price them on their own pricing pages.

Related questions

Answered once, then it answers itself

While a customer types a title, the form shows questions that look like it. Many people stop there and read the answer.

Every thread also carries up to five related questions beside it, so one answer leads to the next one.

  • Duplicate suggestions while the title is being typed
  • Up to five related questions beside every thread
  • One accepted solution, pinned under the question

The shelf you are pricing

Six knowledge base tools, in plain words

How much does knowledge base software cost? It depends on the tool and the seat count. The numbers move, so we do not print them here. What follows is what each tool is for, and what to weigh. If you are pricing knowledge base software today, read this as the cheaper shelf beside it.

  1. 1

    GitBook

    Best for
    Product and developer documentation teams who write in git and publish a docs site.
    Price
    Per plan, and per seat on some tiers. Check their pricing page for the number today.
    Does well
    A real editor with version control and a clean reading experience. Developers are happy to live in the docs site it publishes.
    Worth weighing
    It is built for documents you plan and maintain. Customer questions still land somewhere else.
  2. 2

    Document360

    Best for
    Support and docs teams who want a full knowledge base platform, public or private.
    Price
    Per plan, and per seat on some tiers. Check their pricing page for the number today.
    Does well
    Article workflow, categories, versions, and reader analytics in one place, with roles for who can publish.
    Worth weighing
    It is a platform, so there is setup to do first. And someone still has to write every article.
  3. 3

    Guru

    Best for
    Internal teams who want their own answers to show up inside the tools they already use.
    Price
    Per plan, and per seat on some tiers. Check their pricing page for the number today.
    Does well
    Short cards, and reminders that ask an owner to verify a card again. A browser extension brings them into the work.
    Worth weighing
    It points at your own staff. A public archive your customers can read is a different job.
  4. 4

    Bloomfire

    Best for
    Bigger companies sharing knowledge across departments, not only in text.
    Price
    Per plan, and per seat on some tiers. Their site asks you to talk to sales for a number.
    Does well
    Search that reaches inside documents and video, so knowledge that is not an article is still findable.
    Worth weighing
    It is an internal knowledge tool. Your customers are not in it, and they cannot ask it anything.
  5. 5

    Helpjuice

    Best for
    Teams who want a hosted public help center and care how the articles look.
    Price
    Per plan, and per seat on some tiers. Check their pricing page for the number today.
    Does well
    Focused on authoring and on customizing a public help center, with reporting on what readers search for.
    Worth weighing
    Same shape as the rest of the shelf: articles written ahead of time, while the questions keep arriving.
  6. 6

    Zendesk Guide

    Best for
    Teams already paying for Zendesk who want help articles beside the work their agents do.
    Price
    Comes with Zendesk Suite plans rather than as a separate line. Check their pricing page.
    Does well
    The articles sit next to the queue your agents already work in. Nobody logs into a second tool to publish.
    Worth weighing
    It is the article half of a suite you are already buying. This is the public question half, and it leaves your queue alone.

AI engines

A copy an AI engine can read

Every public thread is also served as raw markdown, with front matter that describes it. AI engines and your own agents read that instead of scraping a page.

demo.myforumcat.com/md/q/105.md
The raw markdown view of a question thread, with YAML front matter, as an AI agent reads it.

The same thread with the layout stripped out. This is the copy an agent asks for.

Questions people ask before switching

Fair questions.

Is this a knowledge base editor?

Answer

No. There is no article editor, no version history, and no publishing workflow. It holds questions and answers, and it is meant to sit beside a knowledge base rather than replace one.

Can we import our old forum or help docs?

Answer

Not today. There is no importer. Most teams start fresh and let the new questions build the archive, which is live in minutes.

We are choosing between Document360 and Helpjuice. Where does this fit?

Answer

Pick between them on the writing experience, because both are article tools. This goes next to whichever you pick, and holds the questions the articles never covered.

We use Confluence or Notion as our knowledge base. Do we need this too?

Answer

Those are good homes for internal documents. Neither gives customers a public place to ask. If you want a Confluence alternative for the customer-facing half, start with the questions.

Will the answers show up in Google and AI engines?

Answer

Every answered question becomes a fast public page with QAPage structured data, a sitemap entry, and a raw markdown view. That is what search engines and AI engines read.

What does it cost in month twelve?

Answer

The same as month one. $9 one time for a portal on a Forumcat subdomain, or $99 a month for your own domain. The bill never grows with traffic or questions.

Do customers need an account to read?

Answer

No. Reading and searching are open to everyone. Signing in is only for asking, replying, and voting, and it is passwordless.
