MindOS

MindOS is a local-first knowledge base developed by the MindOS Team, currently available at version 0.4.16, with a total of 26 versions released over the course of its development. The software is designed around a single core idea: providing one shared space where users think and where their AI agents act. Rather than scattering notes, context, and knowledge across multiple tools and AI services, MindOS positions itself as a unified knowledge base that is shared between the user and every AI the user works with. Its local-first approach means the knowledge base lives on the user's own machine, keeping personal thoughts and data under the user's direct control rather than in a remote service. The publisher describes the product with the tagline "MindOS is where you think, and where your AI agents act," emphasizing the dual role it plays for both human thinking and AI-driven activity. A further message from the publisher, "Share your brain with every AI — every thought grows," captures the intended use case: instead of re-explaining context to each separate AI tool, users maintain a single knowledge base that all of their AI agents can draw from, so accumulated thinking compounds over time rather than being lost between sessions or platforms. Relevant use cases include personal knowledge management, note-taking, organizing thoughts and ideas, and supplying persistent context to AI agents so they can act on the user's stored knowledge. In terms of category, MindOS fits within knowledge management and personal knowledge base software, and it also intersects with the growing field of AI agent tooling, since it is explicitly built to serve as shared infrastructure between a user and multiple AI systems. The version number 0.4.16 indicates the software is in an early, pre-1.0 stage of development, and the existence of 26 recorded versions reflects ongoing iteration by the MindOS Team.
