How Knowledge Base Tools Price Editors and Sites

A knowledge base invoice depends less on how much you write than on what the vendor counts. One charges per published site, one per person who logs in, and one sells a fixed block of users.

GitBook lists Essential at $65 per site a month billed annually. HelpDocs lists Sprout at $99 a month for five editors. Helpjuice lists its entry plan at 249 a month for thirty users.

Those three numbers are not comparable until the unit under each one is written down. That is the whole job of reading a page like this.

GitBook bills the site, then bills the people on top

GitBook's summary line is unusually direct: "Essential starts at $65 per site/month and Ultimate at $249 per site/month when billed annually, with additional team members at $12 per user/month."

Two charges, two units. A single documentation site with four writers on Essential is $65 plus $12 a head, which the editorial arithmetic puts at $113 a month.

The per-site part is the one that surprises people. A company that publishes product docs, an internal handbook and a partner portal is buying three sites, not three sections.

AI arrives as a dollar-denominated allowance rather than a feature tick. Essential "includes $20 of AI credits" shown as 2,000 credits, and Ultimate "includes $100 of AI credits" shown as 10,000 credits.

Divide either pair and a credit is one cent. That is the clearest AI price per unit on any page in this set, and it makes overflow easy to forecast.

A free plan exists for individuals, and the annual toggle advertises "2 months free". Enterprise pricing is described as customized, with SAML SSO sitting on that tier.

Identity features landing only on the top tier is the standard shape across business software. How help desks price seats and AI resolutions shows the same gate in a neighbouring category.

HelpDocs counts editors and gives readers away

HelpDocs prices three plans by how many people can log in. Sprout is $129 a month billed monthly or $99 billed annually, and includes five editors.

Bloom is $299 or $239 annually for fifteen editors. Harvest is $499 or $399 annually for twenty-five editors, plus two additional domains.

The seat rule is spelled out on the comparison table: "Only pay for people who log in to your dashboard. Anonymous viewers are unlimited." Extra users are listed at $25 each per month.

Annual billing is advertised as 20 percent off. Checking Sprout, $99 against $129 is a 23 percent reduction by our arithmetic, so the badge understates the gap slightly at that tier.

The per-editor rate moves with the plan. Sprout works out at $19.80 per editor a month on annual billing, and Harvest at $15.96, both by our arithmetic.

• AI credits scale with the tier: 1,000 a month on Sprout, 5,000 on Bloom, 10,000 on Harvest.
• Contact form submissions are capped at 1,000, 5,000 and 25,000 a month across the three plans.
• Machine translations are listed at 10, 100 and 500 a month.
• Analytics history runs 90, 180 and 365 days, so the cheapest plan also forgets the fastest.
• Languages are capped at 3 on Sprout and 20 on Bloom, and listed as unlimited on Harvest.

Five metered limits behind one price is a lot to track. The same layering shows up in how automation tools price runs and operations, where two meters sit on one invoice.

Helpjuice sells blocks of users, and draws the dollar sign as a picture

Helpjuice lists three plans at 249, 449 and 799 a month. Users included are 30, 100 and unlimited, with file storage of 12GB, 24GB and 38GB respectively.

Worth noting for anyone copying figures off the page: the currency mark is drawn as an image rather than written as text, so the rendered figure reads "249 /mo" with no symbol beside it.

The block model flips the usual arithmetic. At 249 a month for thirty users the per-user rate is $8.30, which is less than half the HelpDocs per-editor rate on any tier.

It only pays off if you fill the block. A five-person team on Helpjuice pays 249 a month for thirty seats and uses five, at roughly $49.80 per person actually working.

Storage is the limit that does not scale with users. Going from 30 users to unlimited roughly triples the price and raises storage from 12GB to 38GB.

Buying a seat block you cannot fill is the mirror image of a seat floor. What a minimum seat count does to small team pricing covers the other direction.

Document360 publishes no figure at all

Document360's pricing page carries no price. Its own page title reads "Get a custom plan tailored to your needs", and the rendered page offers a demo booking rather than a plan table.

We searched the fully rendered page for any dollar amount on October 29, 2026 and found none attached to a plan. That is a sales process, not a pricing page.

This is not automatically a worse deal. It does mean the tool cannot enter a shortlist built on published numbers, and it makes a like-for-like comparison impossible without a call.

Quote-only pricing has a second cost, which is time. The exit terms usually surface just as late, as described in what happens to your data after you cancel.

What to work out before you commit

• Count your published sites, not your articles. GitBook charges $65 a month per site on Essential before anyone is added.
• Count only the people who log in. HelpDocs states that anonymous viewers are unlimited and bills just dashboard users.
• Divide the block. Helpjuice's 249 a month covers thirty users, which is cheap at thirty and expensive at five.
• Check the storage row separately. Helpjuice lists 12GB, 24GB and 38GB, and that figure does not move with usage.
• Price the AI allowance per credit. GitBook's $20 for 2,000 credits makes a credit exactly one cent.
• Re-do the annual discount yourself. HelpDocs advertises 20 percent and the Sprout pair works out to 23.

The reading method carries over to any seat-priced tool. How per-user pricing works with contractors and how help desks price seats and AI resolutions apply it next door.

If a support team will also own the content, price both tools together. How client reporting tools price dashboards and sources shows how quickly stacked per-item fees add up.

Frequently asked questions

Which knowledge base tool is cheapest for a small team?

On the pages read October 29, 2026, GitBook. Essential is $65 per site a month billed annually plus $12 per user, so a one-site team of three is $101 a month by our arithmetic.

Do readers of my knowledge base need paid seats?

Not on HelpDocs or GitBook. HelpDocs states that anonymous viewers are unlimited and that you only pay for people who log in to the dashboard. Helpjuice counts users rather than readers in its 30 and 100 blocks.

How much does GitBook cost for more than one documentation site?

Essential is listed at $65 per site a month billed annually, so three sites is $195 a month before team members, each of whom is listed at $12 per user a month.

Does Document360 publish its prices?

Not on its pricing page. The rendered page read October 29, 2026 contained no plan price and the page title reads "Get a custom plan tailored to your needs", so a quote request is the only route.

What do knowledge base AI credits actually cost?

GitBook is the clearest: Essential includes $20 of AI credits shown as 2,000 credits, which is one cent per credit. HelpDocs includes 1,000 credits a month on Sprout without publishing a per-credit price.

Bottom line

Pick the unit that matches your shape. One site and many writers favours HelpDocs, several sites and few writers favours GitBook, and a large team on one site favours the Helpjuice block.

Then check what the cheap plan forgets. Sprout keeps 90 days of analytics and caps you at three languages, and neither limit appears in the headline price.

All figures reflect the vendors' own pricing pages as read on October 29, 2026 and can change without notice. Confirm the editor count and site count at the checkout step before paying for a year.
