ProProfs prices by author and add-on. Ferndesk includes everything and keeps itself accurate.

When to choose Ferndesk, and when to choose ProProfs
Choose Ferndesk if
- You ship software every week and the articles fall behind.
- You want merged pull requests and support tickets to drive doc updates.
- You want your own domain, the widget and AI answers without add-ons or per-author pricing.
- You want to get started today, with your first articles drafted from your codebase.
Choose ProProfs if
- You want a free plan to start.
- You already use ProProfs’ help desk, chat or training tools.
- You want interactive demos and recorded step-by-step guides.
- You need an internal wiki priced per viewer.
ProProfs grows by author and add-on. Upkeep stays manual.
Teams move when per-author pricing and add-ons add up, and articles still go stale between releases.
Priced per author, plus add-ons
Business is $69 per author a month billed yearly, or $99 month to month. A custom domain and removing ProProfs branding cost another $300 a year.
Self-healing is still coming soon
ProProfs lists its self-healing knowledge base on the top plan under “Coming Soon”. What ships today, Auto-Sync to UI Changes, covers step-by-step guides you record, not your articles.
Tickets need the full suite
Turning support tickets into articles comes with the Customer Delight Suite, from $499 a month. The knowledge base on its own has freshness scores and failed-search reports.

ProProfs lists self-healing as coming soon. Fern already drafts the fixes.
Fern watches the places docs go wrong: merged code, support conversations and the live product. The fixes arrive drafted, and nothing publishes until someone on your team approves it.
Every merged PR, checked for doc impact
Fern reads each pull request you merge, finds the help articles it made wrong, and drafts the edit with a link to the change it came from.
Support tickets turned into articles
She reads resolved conversations in Intercom, Zendesk, Help Scout, Crisp and other inboxes, spots the questions your docs do not answer, and drafts the missing article.
Every article checked against the product
Verification reads each article claim by claim and checks it against your codebase, your website and the live product. Anything that is no longer true becomes a drafted fix, and scheduled audits repeat the check.
Screenshots retaken from your real UI
When a screen changes, Fern recaptures the screenshot from your product, so articles stop showing last year’s design.
Move your knowledge base in minutes
Ferndesk has a dedicated ProProfs importer. It rebuilds your folders, rewrites internal links, and redirects your old URLs to the new pages so links and search rankings survive the move. If something will not import cleanly, we do it with you.
What comes across
- Your folders and articles
- Article content and images
- Internal links, rewritten to the new pages
- Your URLs, with redirects from the old paths
The importer reads your public knowledge base. Private sites move from an export, or we import them with you.
