KnowledgeOwl flags articles by age. Ferndesk keeps itself accurate.

When to choose Ferndesk, and when to choose KnowledgeOwl
Choose Ferndesk if
- Your product ships every week and articles go stale between reviews.
- You want your own domain and the widget without moving to a higher plan.
- You want several languages in one help center, not one knowledge base per language.
- You want merged pull requests and support tickets to drive doc updates.
Choose KnowledgeOwl if
- You have dedicated writers who want versions, review statuses and a style guide.
- You want full HTML, CSS and JavaScript control of the design.
- You need an internal knowledge base with required reading for reader groups.
- You want a 30-day trial and regular onboarding calls.
KnowledgeOwl adds up as you grow. Upkeep stays manual.
Teams move when authors, knowledge bases and AI credits add up, and articles still go stale between reviews.
The basics start on Pro
A custom domain, the help widget and custom HTML start on Pro at $250 a month, with 1 author. Each extra author is $25 and each extra knowledge base $50.
AI runs on monthly credits
Basic includes 100 AI credits a month and Pro 500, shared by the chatbot and writing help. When they run out, the chatbot stops until next month or you buy more.
Review dates, not reviews
Articles move to Needs Review after a set age, so a person knows to look. Nothing reads your code, your tickets or your product to find what changed.

KnowledgeOwl marks articles for review. Fern reviews them and drafts the fix.
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 KnowledgeOwl importer. It rebuilds your nested categories, brings category pages and articles across, 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 categories, nested categories and articles
- Category pages and article content
- Old article aliases, pointed at the new pages
- Your URLs, with redirects from the old paths
The importer reads your public knowledge base. Private articles move from an export, or we import them with you.
