Questions to ask about price
- Is there a minimum number of seats or a minimum annual spend?

Is Nuclino worth the price?
Nuclino is good value for small teams that want a simple, fast wiki with a free plan, and for teams that need SAML SSO at a lower tier than enterprise suites, since it sits on Business. It gets awkward because guests and read-only members count as users, which inflates seat totals for wikis with many readers. Teams over 100 users, those with heavy workflow or approval needs and those building customer help centers will want a different tool.
Worth it if
- Small teams wanting a simple, fast wiki with a free plan.
- Teams that need SAML SSO at a lower tier than enterprise suites.
Look elsewhere if
- Teams over 100 users (custom talk needed)
- Heavy workflow or approval needs.
- Customer help centers.
Pricing details most reviews leave out

Our verdict on Nuclino
Nuclino is a lightweight wiki and workspace with a free tier and three plans: Free, Starter and Business. Free covers up to 50 items, 3 canvases and 2GB total storage. Nuclino lists no dollar amounts for Starter or Business on the pricing page, so you cannot calculate a bill without checking the vendor. Yearly billing saves up to 25%, and Starter has a 14-day trial.
The cost catch is seat counting: guests and read-only members count as users, so a wiki shared widely costs more than it appears. Business adds Sidekick AI, audit log, SAML SSO, a custom domain and unlimited history. Above 100 users you need a custom plan. G2 rates it 4.7 out of 5, but across only 24 reviews, so weigh that lightly.
