Notion is a cloud-hosted, freemium all-in-one workspace (Free through $20/member/month Business, plus custom Enterprise) that stores data in its own databases…
Best for Notion: Teams that want a connected, cloud-based workspace combining docs, wikis, tasks, and databases with configurable AI agents, paying per member ($10 Plus or $20 Business).
Best for Obsidian: Individuals who want to own their notes as local plain-text Markdown files, extend the app via its open plugin API and thousands of community plugins, and only pay if they need optional Sync ($4/user/month) or Publish ($8/site/month).

Key Differences
Data Storage Model
Notion: Notion stores content in its own cloud-hosted block-based pages and databases.
Obsidian: Obsidian stores notes as local plain-text Markdown files that the user controls, explicitly avoiding lock-in.
Local plain-text storage means notes remain readable and portable even if the app disappears, unlike a proprietary cloud database.
Free Plan Depth
Notion: Notion has a free plan, but paid tiers (Plus $10, Business $20/member/month) add collaboration limits, admin controls, and advanced features.
Obsidian: Obsidian's entire core app is free with no feature limits at all — payment is only required for optional Sync, Publish, or organizational Commercial License add-ons.
A feature-complete free core versus a free tier that gates advanced features changes how much value is available before paying.
Extensibility
Notion: Notion offers flexible database views (table, board, calendar, timeline) and configurable AI Custom Agents.
Obsidian: Obsidian has an open plugin API and thousands of community plugins and themes for deep customization.
Plugin-based extensibility lets individual power users tailor the tool precisely to their workflow, beyond what built-in views offer.
Collaboration
Notion: Notion is built natively for team collaboration in a shared cloud workspace.
Obsidian: Obsidian's collaboration is limited to what the paid Sync add-on enables, including "shared vault collaboration."
Teams that need many people editing shared content simultaneously need native collaboration, not an add-on.
Commercial/Organizational Licensing
Notion: Notion's paid Business plan ($20/member/month) already covers organizational/team usage.
Obsidian: Obsidian requires a separate $50/user/year Commercial License for organizational use, on top of the free core app.
Organizations need to budget for a distinct commercial license with Obsidian, which isn't required with Notion's standard team plans.

Pricing Compared
Starting price reflects the lowest paid tier, not the full cost for every team size or usage level.
Notion
Free — $0 Free
Plus — $10/user/month (annual) or $12/user/month (monthly) Monthly or annual billing
Business — ~$20/user/month (annual) Monthly or annual billing
Extremely flexible block-and-database model adapts to many different workflows
Can replace several single-purpose tools (wiki, docs, task tracker) in one workspace
Large ecosystem of templates and community resources
Increasingly capable AI features for summarization, search, and multi-step tasks
Generous free tier for individuals and students
Cons
Full Notion AI functionality is now limited to Business and Enterprise plans
Flexibility means more setup and configuration effort than opinionated tools
Performance can slow down in very large, deeply nested workspaces
Free plan caps file uploads and page history, limiting solo use over time
Enterprise pricing requires a custom sales conversation rather than transparent list pricing
Obsidian
Pros
Core app is free for personal and commercial use with no feature paywall.
Local-first, plain-Markdown storage gives users full data ownership and long-term durability.
Extremely deep customization through a large community plugin and theme ecosystem.
Works fully offline with no required account or internet connection for the base app.
User-funded business model keeps incentives aligned with users rather than investors.
Cons
No built-in real-time collaboration, unlike Notion or Google Docs.
Steeper learning curve than simpler note apps, especially when configuring plugins.
Sync and Publish are paid add-ons rather than included with the free app.
Heavy reliance on third-party community plugins can introduce inconsistency or occasional compatibility issues after updates.
Mobile app experience, while functional, is generally considered less polished than the desktop app.
Use Cases
Choose Notion: Teams that want a connected, cloud-based workspace combining docs, wikis, tasks, and databases with configurable AI agents, paying per member ($10 Plus or $20 Business).
Choose Obsidian: Individuals who want to own their notes as local plain-text Markdown files, extend the app via its open plugin API and thousands of community plugins, and only pay if they need optional Sync ($4/user/month) or Publish ($8/site/month).
Need both: A person could keep a private, local Obsidian vault (using the free core app and plugin ecosystem) for personal notes and knowledge management while using Notion for team-facing collaborative docs and databases at work — a realistic split between individual-local and team-cloud needs.
Notion
Team knowledge base and wiki — Companies build a searchable internal wiki for documentation, onboarding, and process guides accessible to the whole team.
Lightweight project management — Teams track tasks and projects using Notion's board and timeline database views instead of a dedicated project management tool.
Personal notes and planning — Individuals use the free plan to organize personal notes, reading lists, and daily planning in one flexible workspace.
Obsidian
Personal knowledge management — Individuals build a linked, searchable 'second brain' of notes using bidirectional links and the graph view to surface connections between ideas.
Long-form writing and research organization — Writers and academics use Obsidian's plain-text, offline-first storage to organize research notes, drafts, and citations without vendor lock-in.
Developer documentation and technical notes — Developers use Obsidian's Markdown-native storage and plugin ecosystem to maintain technical documentation and code-adjacent notes alongside version control.
