Nuclino: features, pricing and who it fits
Nuclino is a lightweight wiki with a free plan limited to 50 items and paid tiers that charge per user, guests included. SAML SSO and an audit log are on Business. Over 100 users requires a custom plan, and G2 reviewers complain that search tolerates typos poorly.
