HelpDocs vs ProProfs Knowledge Base
An honest look at how the two knowledge base platforms actually differ, from per-author pricing to what sits behind ProProfs' top plan.
The verdict
ProProfs Knowledge Base is the cheaper way to start. It has a genuinely free forever plan, paid plans from $49 per author, and it is easy for non-technical authors to pick up. HelpDocs costs more on day one but charges one flat price with editors, AI credits, a custom domain, and API access already in it, instead of metering every author and reserving the API, SSO, and audit logs for the top tier.
HelpDocs is best for
Teams with more than a couple of authors who want flat, predictable pricing that does not climb with every writer, AI and a custom domain included, an API on every plan, and deeper customization.
ProProfs Knowledge Base is best for
Solo authors and very small teams on a tight budget, especially anyone who can live inside a free 25-page help center, plus organizations that need many separate branded sites or already run the wider ProProfs suite.

Pricing
Pricing, side by side
Credit where it is due: ProProfs publishes its prices, which puts it ahead of the quote-only end of this market, and there is a real free forever plan. The catch is the model. Paid plans are billed per author, so the bill grows with every person who writes or edits, and a custom domain plus white labeling is a separate $300/year add-on on every tier. The figures below are the annual-billed rates shown on proprofskb.com as of July 2026, and ProProfs advertises up to 50 percent off for paying annually, so month-to-month costs more.
Sprout
$99/mo billed annually. 5 editors, 1,000 AI credits/mo, AI meta features, unlimited free public viewers, custom CSS.
Bloom
$239/mo billed annually. 15 editors, 5,000 AI credits/mo, AI drafts, rewrites, Ask AI, and AI style enforcement, audit trail, 20 languages, Lighthouse widget, custom JS and HTML templating.
Harvest
$399/mo billed annually. 25 editors, 10,000 AI credits/mo, unlimited languages, permissioning, SSO. Extra editors on Harvest are $25 each per month.
Free
1 author, up to 25 pages, unlimited public views, help widget, revision history. No AI Writer or AI Search.
Essentials
$588 per author billed annually. 1 site, 300 pages, AI Writer, AI Search, AI SEO, custom CSS, API documentation articles.
Business
$828 per author billed annually. 3 sites, 500 pages, AI Style Guide, version control, page and folder restrictions, 60+ languages, data export, platform migration.
Business Complete Elite
$948 billed annually, annual plans only. Unlimited sites and pages, API, webhooks, SSO, SCIM, audit logs, approval workflow, 100+ integrations. The page labels this the cost for unlimited authors, and its AI chatbot and AI agents are marked Coming Soon.
Internal knowledge base
Priced per user with a 50-user minimum, billed annually ($11.88 to $35.88 per user per year) across the same three tiers.
Custom domain and white label
Add-on required on any plan to use your own domain and remove the Powered by ProProfs mark.
Customer Delight Suite
Annual plans only. Bundles the knowledge base with ProProfs Help Desk, Live Chat, Survey Maker, and Qualaroo, plus white-glove data migration.
The bottom line: For one or two authors ProProfs is clearly cheaper, and the free plan really is free. The maths flips as your team grows. At $49 to $79 per author per month, five authors is roughly $245 to $395/mo and ten authors is roughly $490 to $790/mo, before the $300/year domain and white-label add-on. HelpDocs is $129/mo flat for 5 editors on Sprout, $299/mo for 15 on Bloom, and $499/mo for 25 on Harvest, with the custom domain, AI credits, API, and unlimited free public viewers already in the price. The second thing to weigh is what sits behind ProProfs' top tier: the API, webhooks, SSO, SCIM, audit logs, and approval workflow are all Business Complete Elite.
Switching
Switching from ProProfs Knowledge Base
This is one of the easiest switches HelpDocs supports, because ProProfs Knowledge Base is a built-in migration source rather than an export-and-reimport job. In Settings > Migrations you pick ProProfs Knowledge Base, and HelpDocs copies your articles and categories across with formatting intact, so there is no CSV to wrangle and no copy and paste. Your ProProfs content stays untouched while the import runs, which means you can keep the old site live and compare the two before you cut anything over. Two things are worth planning for: any custom header HTML or CSS needs rebuilding against your HelpDocs theme, and if you were paying the $300/year ProProfs add-on for your domain, you can point that same domain at HelpDocs at no extra cost.
- 1 In HelpDocs, go to Settings > Migrations and choose ProProfs Knowledge Base as your source.
- 2 Connect your ProProfs site and let HelpDocs copy your articles, categories, and images.
- 3 Review formatting, rebuild any custom header CSS against your HelpDocs theme, and tidy your categories and navigation.
- 4 Point your custom domain at HelpDocs and add redirects from the old ProProfs URLs.
- 5 Turn on Ask AI and the Lighthouse widget, then invite your team (public viewers are always free).
