Nuclino

Overview

Nuclino is a shared workspace for team documents, knowledge, and projects, best suited to groups that want written and visual work organized together. Its range of views and collaborative documents make it flexible, but the Free plan’s small item and storage allowances make it a starting point rather than an unrestricted team workspace.

Key features

Each item is a collaborative document that can hold notes, tasks, flowcharts, and embedded files. That gives teams a place to keep reference material alongside project work, though teams with larger libraries will need to account for the Free plan’s 50-item ceiling. List, board, table, and graph views provide distinct ways to arrange work and knowledge; the graph view suits connected information, while boards offer a task-oriented layout. An infinite canvas adds room for whiteboards and diagrams, but Free users are capped at three canvases.

Search filters, keyboard shortcuts, slash commands, and Markdown support help people find and edit content in different ways. Sidekick can draft content, generate images, and summarize notes. The API can create and update content, retrieve it as Markdown, search it, list items, and fetch users. MCP connections support Claude, ChatGPT, and Cursor, while integrations include Slack, Microsoft Teams, Discord, Google Drive, OneDrive, Dropbox, Jira, and embeddable diagram and media tools.

Nuclino says it encrypts data in transit with TLS and at rest with AES-256, and keeps automatic encrypted database backups for up to 60 days. It states a GDPR commitment and displays ISO 27001, ISO 27018, and SOC2 standards on its security page. These controls may matter to teams assessing a shared knowledge workspace, while SAML SSO and advanced security controls are Business-plan features.

Pricing

Nuclino has a Free plan at no cost. It allows up to 50 items across all workspaces, three canvases, and 2GB of total storage. Help center access and basic email support are included. These limits suit small teams evaluating the workflow or maintaining a compact workspace, but are restrictive for a growing knowledge library.

Starter has custom pricing, billed monthly or yearly, with up to 25% off on yearly billing. It adds unlimited items and canvases, admin tools, publishing, 30-day version history, and 10GB of storage per user, plus priority email support. It is the practical step up for teams that have outgrown Free’s caps but do not need the Business feature set.

Business also has custom pricing and monthly or yearly billing, with up to 25% off on yearly billing. It includes Sidekick, audit logs, team insights, advanced security controls, SAML SSO, a custom publishing domain, unlimited version history, and 20GB of storage per user. This tier is aimed at teams that need those administrative, security, AI, or publishing capabilities; its extra storage and features come with a price that should be weighed against team requirements.

Nuclino offers a 14-day trial. The plans do not state a seat minimum or trial renewal terms.

Platforms

Nuclino supports Android, iOS, Linux, macOS, Windows, and the web, as well as an API. That breadth makes it relevant to teams working across desktop and mobile environments, while the API provides an option for content workflows beyond the interface.

Who it's for

Nuclino is a strong fit for teams that want shared documents, several ways to organize information, and a canvas for visual collaboration in one workspace. It is less compelling for teams that need a large free knowledge base, since Free is limited to 50 items, three canvases, and 2GB total storage. Teams requiring SAML SSO, audit logs, unlimited version history, or a custom publishing domain need Business.

Pros and cons

• Pros: Collaborative documents combine notes, tasks, diagrams, and embedded files, keeping related project and reference work together.
• Pros: Four views and an infinite canvas support both structured and visual ways of organizing work.
• Pros: Broad integrations, API access, and MCP connections extend how teams can work with content.
• Cons: Free’s 50-item, three-canvas, and 2GB limits can constrain a team workspace as it grows.
• Cons: Version history is limited to 30 days on Starter; unlimited history and SAML SSO require Business.
• Cons: Starter and Business have custom pricing, so teams cannot compare their costs from a published amount.

Alternatives

For a knowledge-base-focused option, compare ProProfs Knowledge Base: its free plan includes one author and 25 pages forever, making it a different fit for a tightly scoped base. Confluence may suit teams who prioritize a free allowance for 10 users, 2GB of file storage, and three active whiteboards per user.

XWiki is an alternative for organizations seeking a self-hosted community edition. Zoho Learn may suit smaller groups that want a free learning-oriented plan for five users, with spaces, manuals, courses, learning paths, and 1GB storage. BlueSpice is an option for those seeking a self-hosted free distribution with business features.

GitBook is worth considering for an individual seeking a free plan with one user and unlimited page views. Wiki.js is a free, self-hosted alternative. Docmost is another alternative.

Verdict

Choose Nuclino if your team wants documents, multiple organizing views, and visual canvases in a single collaborative workspace. Its main trade-off is that Free has tight capacity limits, while the expanded tiers have custom pricing; teams with larger needs should compare the required Starter or Business features against that cost before committing.
