Outline review
A structured, self-hosted knowledge base with collaboration, AI answers, and integrations.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Outline is a collaborative knowledge base and wiki for organizations that need structured internal documentation, public content, or both. Teams can organize information into collections and nested documents, write in Markdown with slash commands and embeds, and collaborate through realtime editing and comments. The product supports web, Windows, macOS, Linux, API access, and self-hosted deployments, making it relevant to teams that want a hosted service or control over their own infrastructure.
The published cloud plans show three monthly tiers: Cloud 1–10 members costs $10 per month, Cloud 11–100 members costs $79 per month, and Cloud 101–200 members costs $249 per month. Each listed tier includes unlimited documents and version history, realtime collaborative editing, AI question answering, SSO authentication, and API and webhooks. The first 30 days are free as a trial, but there is no free plan. For teams evaluating the product, the main value is the combination of structured documentation, full-text search, AI answers, and revision history rather than a narrow wiki editor alone.
Outline also fits teams with an established software ecosystem. Integrations include Google, Microsoft, Discord, OpenID Connect, Slack, Figma, GitHub, GitLab, Linear, Zapier, Make, Google Analytics, Matomo, Umami, and Notion. Internal permissions, groups, guest access, public sharing, custom domains, and analytics integrations extend its use across private and published knowledge. Teams seeking self-hosting, collaboration, and integrations should find a strong fit; organizations requiring a free plan or a listed cloud tier above 200 members should consider whether the available options match their needs.
