Helpjuice

A documentation team outgrowing its wiki wants two sites at once: a public help centre matching the brand, and an internal one only staff can reach. Helpjuice runs both from one account and bills the account, not the writers.

Three flat monthly prices, no per-seat line anywhere: $249 for 30 users, $449 for 100, $799 for unlimited. A user is anyone added in the Users section, read-only Internal Viewers included; customers reading the public site are not. Four things separate the tiers: user count, file storage, SSO, and the AI Suite. Swifty, the chatbot that answers from your own articles and cites them, starts at $449. AI translation meters separately at $0.00015 per character after 30 free translations.

Reach the user ceiling and readers keep reading, but no login can be added until the plan moves up, so the 31st person costs $200 a month. There is no annual price, no free plan and no enterprise tier. SSO and the AI Suite are both missing from the $249 plan, hosting is United States only, and no SOC 2 or ISO 27001 report is claimed anywhere. Self-serve import reads .xls and .csv; every other format goes to an email address.

KnowledgeOwl charges $100 plus $25 per author and never counts readers, cheaper below seven writers and dearer past thirty. Document360 sells the same shape and prints no number at all. HelpKit runs $15 to $79 per site and leaves the articles in Notion. All four sit in knowledge base software.
