Blinko is an open-source, privacy-focused note-taking app designed for quickly capturing short “card” notes and organizing them over time. It adds AI-assisted retrieval using RAG, enabling natural-language search across your personal knowledge base while keeping data under your control.
Key Features
- Card-style note capture optimized for quick, lightweight writing
- Markdown-based notes for simple formatting and portability
- AI-enhanced retrieval using RAG for natural language querying of notes
- Self-hosted data storage emphasizing data ownership and privacy
- Web app built with a modern UI stack
- Optional multi-platform desktop experience via Tauri
Use Cases
- Personal knowledge management with fast capture of ideas and snippets
- Searching a private notes archive using natural-language queries
- Lightweight alternative to heavier note systems for daily journaling and memos
Limitations and Considerations
- AI/RAG features may require additional configuration and external model/provider choices depending on your setup
Blinko fits users who want a clean, fast note workflow with Markdown and the option to add AI-powered retrieval. It is especially suited to individuals prioritizing privacy and control while still benefiting from modern AI search.
