engram
"Persistent AI memory backend with semantic search and knowledge graph. Stores episodic, semantic, and procedural memories in a local SQLite database and retrieves the most relevant ones using vector similarity and graph traversal. Use when you need to remember information across sessions, recall past decisions, store facts about a project, detect contradictions between beliefs, or give any AI model a persistent growing brain. All embeddings run locally - no API keys required."

Recommended workflow
Session start → recall_context("current task or question")
During session → store_memory("decision or finding", type="episodic")
Session end → store_memory("session summary", importance=0.8)Key tools
recall_context— primary recall tool. Assembles the most relevant memories for a query and returns formatted context ready to inject into prompts. Call at the start of every session.store_memory— saves episodic events, semantic facts (type="semantic",concept="...") or procedural patterns (type="procedural").search_memory— semantic similarity search with optional type filter and threshold.check_contradictions— detects memories that conflict with a given memory ID.resolve_contradiction— resolves conflicts via strategy:keep_newest,keep_oldest,keep_important,keep_both, ormanual.decay_sweep— runs Ebbinghaus forgetting curve decay; archives stale memories and consolidates old episodes into facts.
