Nexsus Reviews & Product Details

Nexsus — The substrate is a private workspace your AI assistant connects to over the open Model Context Protocol (MCP). Once connected, your assistant gains a persistent, structured memory: it reads, stores and reasons over your data across every session, instead of starting from scratch each conversation. Every customer gets a separate, walled-off workspace, isolated at the database level — your data is never mixed with anyone else's. Nexsus understands meaning, not just values: records carry structure and are searchable semantically, and the platform keeps a complete history of every change so nothing silently drifts or breaks. Every write is checked against the workspace's own correctness rules before it's accepted, and if a write would break structure, you get back the specific reason, not a generic error. Nexsus works with Claude, ChatGPT, Gemini, Claude Desktop, and any other client that speaks the open MCP standard — one workspace, every assistant. There's nothing to host: sign up, add your Nexsus MCP server URL as a connector, authorise once with OAuth, and you're working. You own your data — export any time, and deleting your workspace deletes it for good.
