causal-memory vs emulo

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.; emulo: Emulo is an open-source tool that mines your past AI agent coding sessions (e.g., Claude Code, Codex) to build a private working profile. This profile, containing unwritten rules and preferences, allows agents to understand your unique workflow and act more like you before every task.

Features

causal-memory logocausal-memory
01Causal 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).
emulo logoemulo
01Mines implicit user behavior from raw AI agent session logs
02Generates a personalized working profile for agents to read
03Supports multiple AI agent platforms and LLMs (e.g., Claude, Codex, Gemini)
04Processes data locally with built-in redaction for privacy

Use Cases

causal-memory logocausal-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.

↳Tailoring AI agent responses and coding style to user preferences
↳Reducing repetitive instructions by providing agents with implicit context
↳Enhancing agent decision-making by learning from past user interactions
↳Integrating a personalized context layer into various agent workflows
