iai-personal-memory-engine vs causal-memory
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.; causal-memory: Causal-memory is an agent memory system with a causal core, uniquely modeling both excitatory and inhibitory connections for robust long-term retention. It enables agents to understand not just what happened, but why it worked or failed, and anticipate outcomes, thereby preventing repeated mistakes.

Features
iai-personal-memory-engine01Persistent, 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.
causal-memory01Causal Core with Excitatory and Inhibitory Connections: Models 'caused', 'enabled', and 'prevented' relationships using typed causal semantics and negative activation spread (GABA analogue).
02Immutable Consolidation & Q-value Dynamics: Employs hippocampus-style SWR (Sleep-Wake Replay) consolidation with LTP/LTD/GC, Q-value dynamics, and novelty-entropy triggers for robust memory evolution.
03Intervention & Counterfactual Query: Enables forward simulation to predict outcomes before action and contrastive analysis to compare outcomes of different alternatives.
04Compaction Survival: Stores causal information in an external SQLite database, making it immune to context window compaction and preserving critical 'why' knowledge.
05Unified Memory Graph: Integrates facts, temporal state, and decision-outcome causal edges into a single graph, accessible via RRF-fused retrieval (BM25 + semantic).

Use Cases
iai-personal-memory-engine↳Enhancing AI coding assistants (e.g., Claude Code, Cursor, Codex CLI) with continuous, personalized long-term memory.
↳Automatically adapting AI assistants to individual user's style, preferences, and recurring patterns over time.
↳Maintaining a comprehensive, secure, and local knowledge base of past interactions for AI reference without explicit 'remember this' commands.
↳Improving AI assistant consistency and reducing redundant questions across multiple sessions.
causal-memory↳Preventing Repeated Mistakes: Agents can recall past `decision → outcome` causal edges, avoiding re-fixing the same bug or repeating past failed architectural choices.
↳Proactive Warning and Intervention: Before committing risky actions (e.g., `git push --no-verify`), the system can fire DANGER warnings based on recorded past negative outcomes.
↳Root Cause Analysis: Trace multi-hop backward causal chains to identify the ultimate root cause of failures or unexpected outcomes.
↳Informed Decision Making: Agents can perform counterfactual comparisons between alternative actions, leveraging known outcomes to choose the best path.
↳Cross-Task Lesson Transfer: Discover and apply meta-edges (e.g., `similar_to`, `repeated`) to transfer lessons and patterns across different tasks or sessions.
