Blinko
Open-source self-hosted AI card-note app with RAG-powered natural-language search over your own notes
0About Blinko
Blinko is an open-source, self-hosted note-taking app built around card notes and quick capture — the model is that ideas arrive in fragments and the tool's job is to catch them before they evaporate, then help you find them again later. Capture is plain text and Markdown, so writing is instant and formatting and sharing stay simple, and notes are organized as cards rather than as a rigid folder hierarchy. Retrieval is where the AI sits: Blinko uses retrieval-augmented generation over your own notes so you can search in natural language and get answers grounded in what you actually wrote, instead of relying on remembering the right keyword. Because it is self-hosted, everything stays inside an environment you control, which is the usual reason people leave hosted note apps once their notes accumulate anything sensitive. It is fully open source with public code, an API, and documentation, and the project actively takes community contributions. Deployment is either a one-click hosted deploy through PikaPods, which starts at a minimum of about $2.3/month and includes a $5 signup credit for new users, with 20% of PikaPods fees generated that way donated back to Blinko, or a self-managed deployment on your own infrastructure. There is a live demo on the site. Community reception centers on the polish of the UI and interaction details relative to the project's age, with users reporting they are gradually migrating off other note products.
