As answered by people managing Mnemoverse and MemoryPlugin.
Mnemoverse's answer
Mnemoverse is a memory API, not a vector database. It scores importance when a memory is written, strengthens the associations between concepts that get recalled together, and re-ranks recall from outcome feedback, so memory improves with use instead of staying static. One API key gives the same memory to Claude Code, Cursor, VS Code, ChatGPT, and any MCP client.
Mnemoverse's answer
You add persistent memory to the AI tools you already use with a single key and nothing to host. Most alternatives are either a vector store you wire into each app or a framework you build an agent in. Mnemoverse is a drop-in memory layer that learns from outcomes and works across tools out of the box, with an open-source MCP server and Python SDK and a free tier.
Mnemoverse's answer
Developers and teams building with AI agents and assistants who want persistent, cross-tool memory without standing up their own memory infrastructure.
Mnemoverse's answer
Mnemoverse began with a simple frustration: AI assistants forget everything between sessions and between tools, so people re-explain context over and over. The team built a memory layer modeled on how human memory works, importance, association, and reinforcement from outcomes, and exposed it over the Model Context Protocol so any tool can share one memory. Its research foundation, the SLoD framework, is published on arXiv.
Mnemoverse's answer
Python and FastAPI on the backend, PostgreSQL with pgvector, HDBSCAN for clustering, sentence-transformers for embeddings, a TypeScript MCP server (npm), and a REST API. Tool integration is through the Model Context Protocol (MCP).
