Nuclino is a lightweight, collaborative knowledge management tool. It is built for writing things down together quickly: documents that several people can edit at once, whiteboard canvases beside them, and the same content viewable as a list, board, table or graph. It is fast, clean, and deliberately simple.
Whale is a SOP, training and knowledge platform. It also stores documented processes, but its job continues after the document exists: assigning it to the right roles, checking people understood it, tracking who has completed it, and giving every process an owner and a review date.
They overlap on writing and storing knowledge, and they separate on what happens after. This page sets out where each one is stronger, using both vendors’ own published information.

Whale is built around the whole life of a procedure, not just its creation. Every SOP has an owner, a version history and a review cycle. You can assign it, confirm it has been read, and test understanding with AI-generated quizzes. Approval flows and expert review cycles keep content trustworthy as it changes, an org chart maps processes to roles, and template libraries mean you are not starting from a blank page. Whale records screen walkthroughs too, with a built-in Step Recorder and Video to SOP, and through Whale’s MCP external AI tools can read and write your documentation directly.
Nuclino is a lightweight, collaborative knowledge management tool, and it is genuinely good at that job. Documents are editable by several people in real time, canvases put whiteboards and diagrams in the same place as the writing, and the same content can be browsed as a list, board, table or graph, which suits teams that think in connections rather than folders. Canvases are something Whale does not offer.
On the Business plan, Sidekick adds AI that answers questions from your own content, drafts and edits text and generates images, alongside SAML single sign-on, an audit log and unlimited version history.
Where it stops is structure. There are no approval or review workflows, no process owners and no review dates, so nothing prompts anyone to confirm a procedure is still correct. Permissions exist as admin, member and guest roles with access and editing restrictions, but there is no governance layer above them and no org chart tying processes to the people who own them. Integrations cover tools such as Slack and Google Drive plus an API, rather than deep connections into systems like Salesforce or Zendesk. And there is no training delivery at all: no courses, quizzes, assignments or completion tracking, so Nuclino can tell you a procedure exists but never that anyone read it.
Whale is rated 9.6 out of 10 for ease of use on G2 and is built so a non-technical team member can document, find and train on a process without help. The setup that matters is structural: where procedures live, who owns them, and who has to read them.
Nuclino is very quick to start and needs almost no training. The editor is minimal, there is little to configure, and a small team can be writing together within minutes. For a startup or a small team that wants documentation live this week with minimal overhead, that simplicity is the whole point and a fair reason to choose it.
Two limits are worth knowing before you commit. The free plan stops at 50 items and 3 canvases with 2GB of storage, which a real documentation project reaches quickly. And version history is capped at 30 days on Free and Starter, so restoring an older version of a procedure needs the Business plan.
The same simplicity is what limits it later. Larger teams that want advanced features, deeper customization and structured control over how knowledge is approved tend to outgrow it, which is the trade-off you are making when you pick it for the speed.
Whale provides a responsive team on live chat and email, plus Coaching & Training services and a Migration service that will take the documentation you already have, wherever it lives today, including exports from other tools, and get it in properly.
Nuclino offers a help centre for everyone, basic email support on Starter and priority support on Business. Admin and security controls follow the same pattern: two-factor authentication, access and editing restrictions, groups and private workspaces are available on the lower tiers, while SAML single sign-on, the audit log and advanced security controls are Business only.
Whale provides live chat and email, plus coaching on how to document well rather than only how to use the software, and a full migration service if you are moving existing content across.

“Next to their very competitive pricing, their support is from out of this world. We used other tools before, but we left a bit hanging in the past regarding the support piece. Stino & his team are always available whenever we have a query which is amazing!”
Jonas M., Small-Business (50 or fewer employees)
“We find Whale easy and intuitive to set up, navigate, and use, and the customer support has been AMAZING. Even though we are still onboarding—and so do not yet have our final structure in place—we can already find any process document within a few seconds (using Whale’s handy search feature).”
Verified User in Financial Services, Small-Business (50 or fewer employees)
“Whale is very user-friendly and has pre-built templates that make design and flow seamless! Automated reminders make it easy to keep important information up to date for staff in our change-oriented organization.”
Julie H., Mid-Market (51-1000 employees)
“The platform is easy to use and even easier to keep up to date. I love their search features, the widget (you can search and find without leaving your current window) and the automations.”
Julianne W., VP of Operations, Small-Business (50 or fewer employees)

Nuclino is a lightweight, collaborative knowledge management tool. It stores documents that several people can edit in real time, adds whiteboard canvases alongside them, and lets you browse the same content as a list, board, table or graph. It is designed to be fast and simple, and it is often used as a lightweight internal knowledge base or documentation space.
Nuclino prices in euros, per user per month, and states that yearly billing saves up to 25%. The free plan is €0 and covers up to 50 items, 3 canvases and 2GB of total storage. Starter is €6 per user per month billed yearly, with unlimited items, admin tools, publishing, integrations, API access and 10GB of storage per user. Business is €10 per user per month billed yearly, adding Sidekick AI, SAML single sign-on, an audit log, team insights, unlimited version history and 20GB per user.
One detail matters when you budget. Nuclino’s own pricing FAQ states that a user is anyone who joins your team, including guests and read-only members, and that upgrading upgrades your entire team. Everyone who needs to read your documentation is a paid seat.
Nuclino stores knowledge. Whale runs it. With Nuclino you get a fast, pleasant wiki where a team can write things down together, with canvases and flexible views. With Whale you get that documentation plus the layer around it: assigning procedures to the right roles, checking understanding with quizzes, tracking completion, and an org chart that maps processes to the people who own them.
Whale and Nuclino are priced differently.
Nuclino charges per user, and by its own definition that means every person on the team, including guests and read-only members. Whale is priced per plan, with unlimited members on paid plans and a set number of creators included, because it is carrying training delivery, assignments, completion tracking and an org chart as well as the documents. If you only need a small team writing and reading a wiki, Nuclino is the cheaper tool and the right one. If most of your people only ever need to read a procedure and prove they did, compare the per-head cost against a plan with unlimited members.
Whale. Nuclino is a fast, lightweight wiki and deliberately stays that way. Whale keeps that searchable simplicity and adds what Nuclino has no equivalent for: assigning a procedure to roles, quizzes to check understanding, completion tracking, process owners with review dates, and an org chart. Paid plans include unlimited members, so read-only people do not each cost a seat.
