Notion vs Obsidian

Cloud-hosted on Notion's AWS infrastructure with SOC 2 Type 2 compliance. Data is encrypted in transit and at rest. Privacy Mode available for AI features. However, data lives on Notion's servers, requiring internet for full functionality. Export options include Markdown, PDF, and HTML.

Local-first architecture stores all notes as plain Markdown files on your device. No account required for core functionality. Optional end-to-end encryption with Obsidian Sync. Your data remains yours forever, accessible with any text editor even if Obsidian disappears.

Deeply integrated AI with Custom Agents, AI Autofill for databases, writing assistance, summarization, and Q&A across your entire workspace. Uses multiple LLM providers. Included in Business tier ($24/user/mo) or as $10/month add-on. Supports voice input and cross-page AI blocks.

No native AI, but extensive plugin ecosystem enables integration with local models via Ollama or cloud APIs through plugins like Copilot. Users bring their own API keys. Community plugins provide AI chat, text generation, and semantic search capabilities.

Real-time collaborative editing with live cursors, comments, mentions, and page history. Granular permissions (view, comment, edit). Guest access for external collaborators. Team workspaces with shared databases and automated workflows. Enterprise SSO and SCIM provisioning.

Limited native collaboration. Obsidian Sync enables vault sharing between users with version history. No real-time collaborative editing. Third-party solutions like Git or external sync required for team workflows. Publish feature allows public sharing but not private collaboration.

Powerful relational databases with multiple views (table, board, timeline, calendar, gallery, list). Formula support, rollups, relations between databases, and filtered views. Database templates and automated properties. Ideal for complex project management and structured knowledge.

No native databases, but Dataview plugin enables querying notes as structured data using JavaScript-like syntax. Kanban and Calendar plugins provide project views. Metadata via YAML frontmatter. Less polished than Notion but highly customizable for technical users.

Basic backlink support with a 'Linked References' section on pages. No visual graph view. Mentions and page links create connections, but the graph is implicit and not explorable. Notion focuses on hierarchical organization over networked thought.

Industry-leading knowledge graph with interactive visualization, local graph views, and global graph exploration. Bidirectional linking with automatic backlink creation. Graph analysis tools show note centrality and orphaned notes. The graph is core to Obsidian's philosophy of connected thinking.

Full-featured iOS and Android apps with offline support for recently viewed pages. Real-time sync when connected. Mobile AI features including voice input. Clean interface optimized for touch. As of 2026, mobile databases and editing match desktop capabilities.

Available on iOS and Android with local vault access. Obsidian Sync keeps mobile and desktop in sync. Improved significantly in 2026 with better editing and plugin support. However, complex plugins and graph views are less usable on small screens.

Custom templates, page icons, covers, and color themes. Formula support for calculated properties. Limited API for integrations and automations. Third-party tools like Notion Enhancer provide additional customization. Locked into Notion's interface paradigms.

Over 1,000 community plugins enabling everything from daily notes to advanced data visualization. Custom CSS themes via community themes or personal CSS snippets. Plugin API for building custom functionality. Core plugins can be disabled for a minimal experience. Ultimate flexibility.

Intuitive block-based editor most users grasp quickly. Database features have moderate learning curve. Template gallery provides starting points. Some power features (formulas, rollups, relations) require learning. Generally approachable for non-technical users.

Markdown editing is simple, but the learning curve steepens for advanced features. Plugin selection requires research and configuration. Knowledge graph concepts (Zettelkasten, MOCs) need study. Best suited for users willing to invest time in their system.
