Engram: A Local Encrypted Memory Vault Unifying Agent Memory Across AI Tools
Acceptable_Leg3950 · reddit · 2026-09-22
A developer released Engram, a local daemon that stores agent memory in a SQLCipher-encrypted vault exposed via a single JSON API, usable by Claude Code, Cursor, and shell scripts. Retrieval combines FTS5 keyword search with local ONNX embeddings (all-MiniLM-L6-v2), plus MCP servers, a Firefox extension, and a ciphertext-only sync relay. A benchmark harness the author built caught a real bug—swapped arguments in the embedder producing near-constant embeddings; after the fix, retrieval beats full-context injection up to 110–150 memories. The daemon is closed-source for now, but the storage format is Apache-2.0.
