Here’s a breakdown of the top contenders to help you make an informed decision.

How do the top small-business KBs compare?

Notion

Verdict: Notion is a versatile all-in-one workspace, ideal for startups and remote teams needing a flexible tool for notes, knowledge bases, and project documentation.

Pricing Tiers: Notion offers a Free plan with unlimited pages and users, but their paid plans, starting at $8/user/mo, unlock advanced features like version history and collaboration tools. The Plus plan is $10/user/mo, adding more advanced permissions and integrations, while the Business plan at $18/user/mo offers admin tools and security settings.

Standout Features: Notion excels with its blocks-based editor, allowing for dynamic document creation, and its AI features like Q&A and summaries. It integrates seamlessly with Slack, Google Drive, Github, and others, making it a powerful hub for team collaboration.

Who Should Not Use It: Teams that need robust offline capabilities or have very large workspaces might find Notion’s performance lacking. The learning curve can also be steep for new users.

Freshdesk KB

Verdict: Freshdesk KB is perfect for SMB support teams looking for a free entry point with potential for scaling. It’s particularly beneficial if you’re already using Freshdesk for ticketing.

Pricing Tiers: Freshdesk KB offers a Free plan, but to tap into its most valuable features, you’ll likely need the Growth plan at $15/agent/mo or the Pro plan at $49/agent/mo, which includes more advanced analytics and AI capabilities.

Standout Features: The AI engine suggests relevant articles directly from support tickets, which can significantly reduce response times. It also supports multilingual knowledge bases, a must-have for global teams.

Who Should Not Use It: If your team requires a sophisticated editor or you’re not already using Freshdesk, you might find the integration and editor capabilities limited.

Zoho Desk KB

Verdict: Zoho Desk KB is a cost-effective choice for SMBs on a budget or those already invested in the Zoho ecosystem.

Pricing Tiers: Zoho Desk’s Free plan is appealing, but the Standard plan at $14/agent/mo and the Professional plan at $23/agent/mo offer more comprehensive features like Zia AI suggestions.

Standout Features: This tool shines with its multi-brand help centers and Zia AI, which suggests articles to streamline support. The deep integration with other Zoho products is also a major plus for existing users.

Who Should Not Use It: Businesses outside the Zoho ecosystem may find other tools more intuitive or better integrated with their current tech stack.

ProProfs KB

Verdict: ProProfs KB is great for SMBs that need a simple, integrated solution for support and training content.

Pricing Tiers: While the Free plan is adequate for starters, the Essentials plan at $30/author/mo and the Premium plan at $40/author/mo offer more robust functionality.

Standout Features: It’s easy to use and ties into the ProProfs training suite, making it ideal for teams that also manage training and quizzes.

Who Should Not Use It: If modern design and advanced search capabilities are critical, ProProfs might seem outdated and basic.

Nuclino

Verdict: Nuclino provides a lightweight, high-speed wiki for small teams that prioritize speed and simplicity.

Pricing Tiers: The Free plan is limited but functional. The Standard plan at $5/user/mo and the Premium plan at $12/user/mo add useful features like advanced permissions.

Standout Features: Its graph and board views for pages offer a unique way to visualize content, and its minimal UI is refreshingly fast.

Who Should Not Use It: Larger teams or those needing extensive customization and advanced features might find Nuclino’s offerings sparse.

Slite

Verdict: Slite is well-suited for asynchronous teams and startups looking for a clean, AI-driven knowledge base.

Pricing Tiers: Slite’s Free plan is generous, but the Standard plan at $6.67/user/mo and the Premium plan at $12.50/user/mo provide enhanced features like advanced search and analytics.

Standout Features: Slite’s AI Ask feature efficiently pulls answers from your documents, making it a powerful tool for quick information retrieval.

Who Should Not Use It: Teams needing extensive integrations or template libraries may find Slite’s options limited.
