Show HN: Domvault – self-hostable second brain with consent-based note sharing (github.com)

Domvault, a new self-hostable second brain platform, has been launched, combining a Markdown-native knowledge engine with advanced features like a self-synthesis loop and an opt-in knowledge sharing layer called Constellation. Unlike typical "second brain" templates that only provide structure, Domvault allows users to generate new connections between their notes automatically while they sleep and control the sharing of their knowledge with others. The platform's architecture promotes privacy and consent by ensuring that users can opt-in to publish individual notes, creating a collaborative knowledge graph that maintains attribution to the original authors. The significance of Domvault lies in its innovative approach to personal knowledge management, emphasizing user control and privacy in an era where data sharing is often exploitative. With its agent contract facilitating seamless integration with existing workflows and a unique self-synthesis mechanism generating "sparks" of idea connections, Domvault fosters a living, dynamic graph of knowledge accumulation. By enabling users to create a "Constellation," the platform aims to build a consensual marketplace of shared intellectual resources, positioning itself as a rich ecosystem tailored for users looking to leverage AI technology in their note-taking and idea organization processes.
