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
Growing documentation teams who want flat, predictable pricing that does not climb with every writer, AI, a custom domain and an API on every plan, and governance like an audit trail, permission groups and SSO without buying the top tier.
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 October 2026, and ProProfs advertises up to 50 percent off for paying annually: month-to-month is $79 per author on Essentials and $99 on Business, and the top tier is annual-only.
Sprout
$99/mo billed annually (23% off). 5 editors, 1,000 AI credits/mo, AI meta features, AI drafts and rewrites, Ask AI, 3 languages, the Lighthouse widget, custom CSS and JavaScript, unlimited free public viewers.
Bloom
$239/mo billed annually (20% off). 15 editors, 5,000 AI credits/mo, AI meta features, AI drafts and rewrites, Ask AI, AI improve, AI style enforcement, 20 languages, audit trail, advanced permissioning, embedded SSO (JWT), the Lighthouse widget, custom CSS and JavaScript, custom HTML templating, unlimited free public viewers.
Harvest
$399/mo billed annually (20% off). 25 editors, 10,000 AI credits/mo, AI meta features, AI drafts and rewrites, Ask AI, AI improve, AI style enforcement, unlimited languages, audit trail, advanced permissioning, SSO with anonymous mode, IP restriction, the Lighthouse widget, custom CSS and JavaScript, custom HTML templating, unlimited free public viewers.
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, or $79 per author month-to-month. 1 site, 300 pages, AI Writer, AI Search, AI SEO, custom CSS and header HTML, API documentation articles.
Business
$828 per author billed annually, or $99 per author month-to-month. 3 sites, 500 pages, AI Style Guide, side-by-side version control, page and folder restrictions, 60+ languages, data export, platform migration, help widget and in-page contextual help.
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. You can see what every other source needs if ProProfs is not the only place your content lives.
- 1In HelpDocs, go to Settings > Migrations and choose ProProfs Knowledge Base as your source.
- 2Connect your ProProfs site and let HelpDocs copy your articles, categories, and images.
- 3Review formatting, rebuild any custom header CSS against your HelpDocs theme, and tidy your categories and navigation.
- 4Point your custom domain at HelpDocs and add redirects from the old ProProfs URLs.
- 5Turn on Ask AI and the Lighthouse widget, then invite your team (public viewers are always free).
Honest trade-offs
Why teams pick one over the other
Why teams choose HelpDocs
- Flat pricing per knowledge base with 5 editors on Sprout, 15 on Bloom, and 25 on Harvest, where ProProfs meters $49 to $69 per author per month on Essentials and Business.
- A custom domain is included on every plan, not a $300/year add-on.
- A read/write REST API on every plan, rather than reserved for ProProfs' top Business Complete Elite tier.
- Ask AI answering readers today, with monthly AI credits in every plan alongside drafts and rewrites, plus style enforcement from Bloom, where ProProfs still lists its AI chatbot, AI agents, and deflection analytics as Coming Soon on its Elite plan.
- Custom JavaScript from Sprout and full HTML templating on Bloom and up, where ProProfs explicitly disallows JavaScript and limits custom HTML to the header.
- Free one-click migration from ProProfs Knowledge Base under Settings > Migrations, plus Zendesk, Intercom, Help Scout, Readme, and Helpjuice.
- Unlimited free public viewers on every plan, where ProProfs prices its internal knowledge base per user with a 50-user minimum.
- Bulk editing across hundreds of articles at once, plus a contributor leaderboard and content health scoring.
- Governance from Bloom rather than the top tier: an audit trail, permission groups and JWT SSO, with SAML and OIDC SSO plus IP restriction on Harvest. ProProfs bundles its audit logs and SSO into Business Complete Elite.
- Built to carry a larger docs team: 25 editors on Harvest with volume discounts on extra editors past 100, version history with side-by-side diffs, and SOC 2 and ISO 27001 certification in progress.

- Swagger and OpenAPI spec import to auto-generate API reference documentation.
- Screen-recording capture, a browser extension, AI screenshot annotation, and interactive demos for building step-by-step guides.

- One vendor and one login for docs, help desk, live chat, and surveys if you want the whole ProProfs suite.
