Nuclino overview: who it is for and what it does.
Nuclino positions itself as a clean, fast internal wiki for teams that find tools such as Confluence or Notion heavier than they need. Reviewers describe a simple, intuitive interface with a low learning curve, a visual canvas workspace unique among wiki tools, and real-time collaboration. Capterra shows 42 reviews on its summary page, and independent pricing comparisons call it the most affordable paid plan in the wiki and knowledge base category at $6 per user per month.
The free plan supports unlimited members with up to 50 items, 3 canvases and 2 GB of total storage, and includes limited Sidekick AI. Starter ($6 annual, $8 monthly) removes the item cap with unlimited items and canvases, 10 GB storage per user, 30-day version history, groups, private and default workspaces, access and editing restrictions, admin tools, publishing and priority support. Business ($10 annual, $12.50 monthly) adds Sidekick AI for Q&A, content generation and image creation, audit log, team insights, advanced security controls, SAML single sign-on, unlimited version history, 20 GB storage per user and a custom publishing domain. Enterprise is available by quote.
Buyers should weigh three limits. The free plan's 50-item cap forces most real teams to Starter quickly, AI is only on the $10 Business plan, and per-user pricing grows linearly, with 50 users on Starter costing about $300 a month. Sources conflict on enterprise controls: GetApp, Toolradar and CostBench list SAML SSO and audit logs on Business, while the comparison site Docsie, which sells a competing product, says Nuclino has no SSO, API access or SOC 2 certification at any price. Confirm security requirements with Nuclino before purchase.
