memEx
Structured personal knowledge base inspired by Zettelkasten and Org mode

memEx is a structured personal knowledge base designed around interconnected notes, topic contexts, and step-based pipelines. It focuses on linking information together for long-term learning and documentation, while supporting collaboration and granular privacy.
Key Features
- Notes for documenting individual items or concepts
- Contexts to capture a topic overview and hotlink related notes
- Pipelines to document processes and attach contexts to each step
- Backlinks to view items that reference the current item
- Multi-user design with sharing and collaboration in mind
- Per-note, per-context, and per-pipeline privacy controls
- Email support via SMTP for account and system emails
Use Cases
- Personal Zettelkasten-style knowledge management with strong linking
- Team documentation space for shared concepts, references, and workflows
- Process/runbook documentation using pipelines for repeatable procedures
Limitations and Considerations
- Requires a PostgreSQL database and a configured SECRET_KEY_BASE to start
- Intended to run behind a reverse proxy when exposed externally
memEx is a practical option for users who want a web-accessible, structured PKM system with explicit support for both collaboration and privacy. Its note/context/pipeline model is well suited to turning scattered information into connected knowledge and repeatable processes.
