iai-personal-memory-engine vs kaeru

iai-personal-memory-engine: iai-pme is an open-source, local-first personal memory engine designed for AI coding assistants, providing persistent, encrypted, and verbatim recall of past interactions. It integrates via the MCP protocol to give AI assistants a long-term memory, automatically capturing and recalling conversation content to enhance assistant adaptability and context.; kaeru: Kaeru is a local-first, cross-agent cognitive engine for LLM agents, providing a typed property graph and a recollection layer for long-term memory. It enables multi-session and multi-agent continuity, allowing agents to maintain full context, follow provenance, and build on shared knowledge over time.

Features

iai-personal-memory-engine logoiai-personal-memory-engine
01Persistent, long-term memory for AI assistants.
02Fully local, encrypted storage and processing with no telemetry or cloud dependency.
03Verbatim recall via vector search combined with a knowledge graph, preserving specific details.
04Automatic conversation capture and intelligent recall injection at session start via MCP hooks.
05Custom-built core components including storage engine, community-detection algorithm, and hyperdimensional memory substrate for optimal performance.
kaeru logokaeru
01Two-tier graph (operational/hippocampus and archival/cortex) for active thinking and settled knowledge.
02Bi-temporal nature with native assertion/retraction history for time-travel queries and non-destructive conflict resolution.
03Per-initiative scoping and layered re-entry to restore project context across sessions and access archival knowledge on demand.
04Optional cross-agent sharing through a cloud tier, allowing trusted teams to share settled knowledge with safety gates.
05Structural recall based on exact name lookup, typed graph traversal, and FTS fuzzy fallback, rather than primarily vector embeddings.
