blinko vs gemini-cli
blinko and gemini-cli are both open-source, TypeScript-based tools, but they serve very different purposes. blinko is a self-hosted, privacy-first personal AI note-taking application designed for individuals who want to manage knowledge, thoughts, and notes locally via a web interface. Its focus is on data ownership, personal productivity, and long-term knowledge management rather than developer workflows. In contrast, gemini-cli is a command-line AI agent that integrates Google Gemini capabilities directly into the terminal. It is aimed primarily at developers, power users, and engineers who want AI assistance for coding, scripting, and automation tasks within their existing CLI workflows. While both are self-hostable and open source, their user experiences differ significantly: blinko emphasizes UI-driven note management, whereas gemini-cli prioritizes speed, flexibility, and integration with development environments. The key differences lie in interface, target audience, and ecosystem maturity. gemini-cli benefits from significantly higher adoption and a permissive Apache-2.0 license, while blinko appeals to users who value privacy, GPL licensing, and a dedicated personal knowledge system.
