AI That Remembers, Learns, and Gets Smarter

Nous is a continuous memory platform for AI agents — inspired by Minsky's Society of Mind and grounded in cognitive science. It gives any LLM persistent memory, decision intelligence, and the ability to learn from its own mistakes.

AI Agents Are Goldfish with PhDs

Every major AI agent today forgets everything between sessions. They're brilliant — and amnesiac.

💀

Without Continuous Memory

Today's AI agents are stateless by default. Every conversation starts from zero.

  • Repeated mistakes — no correction learning
  • Lost context — user re-explains preferences every session
  • No skill accumulation — can't get better at what it does
  • No decision tracking — no idea what worked or failed
  • No identity — each session is a different agent
🧠

With Nous

A cognitive memory layer that makes any LLM agent persistent, learning, and self-improving.

  • Correction Learning — mistakes become permanent guardrails
  • 5 memory types — episodic, semantic, procedural, working, censors
  • Sleep consolidation — autonomous overnight memory optimization
  • Decision intelligence — Brier-scored prediction calibration
  • Persistent identity — same agent personality across all sessions

Brain / Heart Duality

Inspired by Minsky's Society of Mind — cognition split into evaluation (Brain) and memory (Heart)

🧠 Brain

Evaluation, judgment, and meta-cognition
  • Quality Scoring — LLM-judged response quality with multi-dimensional rubric
  • 🎯
    Brier Calibration — tracks prediction accuracy over time, self-correcting confidence
  • 📊
    Decision Tracking — every decision logged with outcome, enabling learning from history
  • 🕸️
    Knowledge Graph — relationships between facts, entities, episodes via pgvector + spreading activation
  • 🔗
    Bridge Definitions — cross-concept connections that enrich retrieval
  • 🛡️
    CEL Guardrails — Common Expression Language rules enforcing behavioral bounds

    Facts — extracted knowledge with confidence scores, categories, decay tracking
  • ⚙️
    Procedures — learned skills with triggers, tools, and effectiveness ratings
  • 🔄
    Working Memory — dynamic per-session context: frame, task, loaded facts, recent episodes
  • 🚫
    Censors — behavioral guardrails that block harmful patterns before they execute
  • 🪪
    Identity — persistent personality and initiation protocol across all sessions

Five Memory Types

Modeled after human cognitive memory systems — each type serves a distinct purpose

📖

Episodic

Conversation summaries with emotional valence, temporal ordering, and importance scoring. What happened and when.

💡

Semantic

Extracted facts with confidence scores, categories, tags, and staleness decay. What the agent knows.

⚙️

Procedural

Learned skills with triggers, tool lists, instructions, and effectiveness ratings. Self-evolving via EvoSkill.

🔄

Working

Per-session dynamic context — current frame, loaded facts, recent episodes, active task, execution ledger.

🛡️

Censors

Behavioral guardrails that block harmful patterns before execution. Regex + semantic matching with severity levels.

Production-hardened capabilities that no other memory platform offers

🌙

Sleep Consolidation

5-phase autonomous cycle: compaction, fact extraction, knowledge graph enrichment, decision calibration, amnesia prevention. Runs between sessions.

Unique
🔧

Correction Learning (F039)

Dual-path detection of user corrections → dual-write to facts + censors. Mistakes become permanent guardrails. MemAlign-inspired.

Live
🧬

EvoSkill

Self-evolving procedural memory. Skills are proposed, tested, merged, and improved autonomously. Transferable and composable.

Unique
🎯

Decision Intelligence

Every decision tracked with confidence, outcome, Brier scoring. The agent literally calibrates its own judgment over time.

Unique
🕸️

Knowledge Graph

Spreading activation across entities and relationships. Graph-expanded retrieval surfaces connections vector search alone would miss.

Shipped
🔍

Hybrid Retrieval

Vector + keyword + graph expansion, fused via Reciprocal Rank Fusion (RRF), then MMR diversity re-ranking. Research-grade retrieval.

Shipped
🖼️

Cognitive Frames

Dynamic context modes (task, research, creative, etc.) that reshape working memory, tool access, and retrieval strategy per situation.

Shipped

DAG Orchestration

Multi-step workflow pipelines with dependency tracking, 3-state exit codes, wave-based execution, and dashboard monitoring.

Live
🛡️

Execution Integrity

Action gating, claim verification, execution ledger, intent tracking. Prevents hallucinated actions and duplicate operations.

What Makes Nous Different

Head-to-head advantages vs. Mem0, Letta, MemOS, and stateless agents

01

Cognitive Architecture, Not Just Storage

Competitors store memories. Nous thinks with them — cognitive loop, frames, deliberation, monitoring. Memory is part of cognition, not bolted on.

02

Self-Improving Intelligence

Brier scoring, correction learning, EvoSkill, sleep consolidation. Nous gets measurably smarter with every interaction — competitors don't.

03

Research-Grounded Design

Built on 12+ cognitive science and AI research papers (Minsky, MemAlign, A-MEM, TIM, ACC). Every feature traces to published research.

04

Production-Grade Safety

Censors, action gating, claim verification, CEL guardrails, execution ledger. Enterprise-ready safety that memory-only platforms lack entirely.

05

Brain/Heart Duality

Unique organ architecture separating evaluation from memory. No other agent platform has this — it enables independent scaling and specialization.

06

4 Unique Capabilities

Pre-prune fact extraction, usage tracking feedback, anti-hallucination safety, and SmartCompress type-aware compression. Verified unique in competitive analysis.
