Show HN: One memory layer across every MCP-compatible AI tool (subvault.ai)

SubVault has launched as a groundbreaking MCP server that enhances AI tools like Claude, Cursor, and Copilot with permanent memory capabilities, fundamentally changing how these tools handle information retention. Unlike traditional AI interactions where context is lost after each session, SubVault captures and retains crucial decisions and ideas, enabling a more coherent and informed user experience. It allows users to recall not just conversations but also critical technical decisions—including architecture patterns, API choices, and debugging solutions—making this information searchable across all sessions. This innovation is significant for the AI/ML community as it addresses a key limitation in current AI systems: the ephemeral nature of conversation contexts. By automatically configuring various tools and extracting structured knowledge based on authority, recency, and relevance, SubVault ensures that users can access pertinent information at any time. Its simple integration process—requiring just a command line input and no upfront payment during the early access phase—democratizes advanced memory capabilities for developers, potentially accelerating productivity and collaboration in AI-driven projects.
