About Claude Brain
Memvid is a portable, single-file memory layer for AI agents that replaces traditional vector databases and RAG pipelines. It stores all data, embeddings, indices, and Write-Ahead Logs in a single .mv2 file, enabling sub-5ms hybrid search (BM25 + vector) with crash-safe deterministic recovery. Designed for enterprise-scale performance, Memvid offers +35% higher accuracy, 93% cost savings, and full portability across on-prem, private cloud, or air-gapped environments. It integrates seamlessly via MCP, SDK, or direct API, supporting time-based queries and offline operation. Trusted by builders at major companies, Memvid is open-source under Apache 2.0 with a free self-hosted tier and paid cloud plans for teams.
Key Features
