Notion vs Sage-wiki
Sage-wiki is the stronger fit for users who want a self-hosted, open-source knowledge base that compiles existing files into linked Markdown, supports graph-aware retrieval, and can serve agents through MCP. Notion remains the better choice for teams that need one integrated workspace spanning collaborative documents, project tracking, calendar workflows, application connections, meeting notes, and broader automation
Decision guide
The practical reasons to choose either option, based on documented capabilities.
Choose Sage-wiki if
- Individuals overlaying AI-assisted search and compilation on an existing Obsidian vault
- Teams building a self-hosted knowledge base from documents, notes, code, email, and other supported files
- Organizations requiring provenance-bearing knowledge graphs, cited Q&A, or MCP access for agents
Stay with Notion if
- The workspace must include documented project-tracking or calendar functionality
- Teams require a documented replacement for Notion's collaborative document editing, application connections, or AI meeting notes
- Migration depends on a documented Notion importer or compatibility path; none is established by the supplied Sage-wiki material
Deployment and operations
Sage-wiki is MIT-licensed and self-hostable. It can be installed as a Go CLI binary; building the web UI also requires Node.js. Prebuilt multi-architecture Docker images and Compose files are documented, but Kubernetes support is not established. Local projects use Markdown output plus SQLite by default, while company deployments can move storage to PostgreSQL/pgvector. Operators are responsible for configuration, model/provider setup, hosting, authentication in front of the server where needed,
Migration considerations
Sage-wiki can overlay an existing Obsidian vault and preserves existing configuration, manifest, and gitignore files unless forced. It also ingests multiple file formats, including Markdown, PDF, Word, Excel, PowerPoint, CSV, EPUB, email, text, transcripts, images, and code. No direct Notion importer or Notion-specific compatibility is documented.
