LLMs forget everything. Every conversation starts from zero. Existing solutions bolt on vector databases and LLM calls for basic recall, adding latency, cloud dependency, and cost to every operation.

Aura gives your AI agent an adaptive cognitive layer: memory that decays, consolidates, learns from feedback, and evolves over time. Every record carries a semantic type (fact, decision, trend, preference, contradiction, serendipity) that shapes how it decays, promotes, and surfaces in recall. Like a brain, not a database. One `pip install`, works fully offline.

```bash
pip install aura-memory
```

```python
from aura import Aura, Level

brain = Aura("./agent_memory")

brain.store("User prefers dark mode", level=Level.Identity, tags=["ui"],
            semantic_type="preference")
brain.store("Deploy to staging first", level=Level.Decisions, tags=["workflow"],
            semantic_type="decision")

context = brain.recall("user preferences")  # <1ms — inject into any LLM prompt
```

Your agent now remembers. No API keys. No embeddings. No config.

## Why Aura?

| | **Aura** | Mem0 | Zep | Cognee | Letta/MemGPT |
|---|---|---|---|---|---|
| **Architecture** | **Cognitive engine** | Vector + LLM | Vector + LLM | Graph + LLM | LLM orchestration |
| **LLM required** | **No** | Yes | Yes | Yes | Yes |
| **Recall latency** | **<1ms** | ~200ms+ | ~200ms | LLM-bound | LLM-bound |
| **Works offline** | **Fully** | Partial | No | No | With local LLM |
| **Cost per operation** | **$0** | API billing | Credit-based | LLM + DB cost | LLM cost |
| **Binary size** | **~3 MB** | ~50 MB+ | Cloud service | Heavy (Neo4j+) | Python pkg |
| **Semantic memory types** | **Built-in (6 types)** | No | No | No | No |
| **Memory decay & promotion** | **Built-in** | Via LLM | Via LLM | No | Via LLM |
| **Trust & provenance** | **Built-in** | No | No | No | No |
| **Encryption at rest** | **ChaCha20 + Argon2** | No | No | No | No |
| **Language** | **Rust** | Python | Proprietary | Python | Python |

### Performance

Benchmarked on 1,000 records (Windows 10 / Ryzen 7):

| Operation | Latency | vs Mem0 |
|-----------|---------|---------|
| Store | 0.09 ms | ~same |
| Recall (structured) | 0.74 ms | **~270× faster** |
| Recall (cached) | 0.48 µs | **~400,000× faster** |
| Maintenance cycle | 1.1 ms | No equivalent |

Mem0 recall requires an embedding API call (~200ms+) + vector search. Aura recall is pure local computation.

## How Memory Works

Aura organizes memories into 4 levels across 2 tiers. Important memories persist, trivial ones decay naturally:

```
CORE TIER (slow decay — weeks to months)
  Identity  [0.99]  Who the user is. Preferences. Personality.
  Domain    [0.95]  Learned facts. Domain knowledge.

COGNITIVE TIER (fast decay — hours to days)
  Decisions [0.90]  Choices made. Action items.
  Working   [0.80]  Current tasks. Recent context.

SEMANTIC TYPES (modulate decay & promotion)
  fact          Default knowledge record.
  decision      More persistent than a standard fact. Promotes earlier.
  preference    Long-lived user or agent preference.
  contradiction Preserved longer for conflict analysis.
  trend         Time-sensitive pattern tracked over repeated activation.
  serendipity   Cross-domain discovery record.
```

One call runs the lifecycle — decay, promotion, consolidation, and archival:

```python
report = brain.run_maintenance()  # background memory maintenance
```

---

## Key Features

**Core Memory Engine**
- **Fast Local Recall** - Multi-signal ranking with optional embedding support
- **Two-Tier Memory** — Cognitive (ephemeral) + Core (permanent) with decay, promotion, and archival
- **Semantic Memory Types** — 6 roles (`fact`, `decision`, `trend`, `preference`, `contradiction`, `serendipity`) that influence memory behavior and insighting
- **Phase-Based Insights** — Detects conflicts, trends, preference patterns, and cross-domain links
- **Background Maintenance** — Continuous memory hygiene: decay, reflect, insights, consolidation, archival
- **Namespace Isolation** — `namespace="sandbox"` keeps test data invisible to production recall
- **Pluggable Embeddings** - Optional embedding support: bring your own embedding function

**Trust & Safety**
- **Trust & Provenance** — Source authority scoring: user input outranks web scrapes, automatically
- **Source Type Tracking** — Every memory carries provenance: `recorded`, `retrieved`, `inferred`, `generated`
- **Auto-Protect Guards** — Detects phone numbers, emails, wallets, API keys automatically
- **Encryption** — ChaCha20-Poly1305 with Argon2id key derivation

**Adaptive Memory**
- **Feedback Learning** — `brain.feedback(id, useful=True)` boosts useful memories, weakens noise
- **Semantic Versioning** — `brain.supersede(old_id, new_content)` with full version chains
- **Snapshots & Rollback** — `brain.snapshot("v1")` / `brain.rollback("v1")` / `brain.diff("v1","v2")`
- **Agent-to-Agent Sharing** — `export_context()` / `import_context()` with trust metadata

**Enterprise & Integrations**
- **Multimodal Stubs** — `store_image()` / `store_audio_transcript()` with media provenance
- **Prometheus Metrics** — `/metrics` endpoint with 10+ business-level counters and histograms
- **OpenTelemetry** — `telemetry` feature flag with OTLP export and 17 instrumented spans
- **MCP Server** — Claude Desktop integration out of the box
- **WASM-Ready** — `StorageBackend` trait abstraction (`FsBackend` + `MemoryBackend`)
- **Pure Rust Core** — No Python dependencies, no external services

---

## Quick Start

### Trust & Provenance

```python
from aura import Aura, TrustConfig

brain = Aura("./data")

tc = TrustConfig()
tc.source_trust = {"user": 1.0, "api": 0.8, "web_scrape": 0.5}
brain.set_trust_config(tc)

# User facts always rank higher than scraped data in recall
brain.store("User is vegan", channel="user")
brain.store("User might like steak restaurants", channel="web_scrape")

results = brain.recall_structured("food preferences", top_k=5)
# -> "User is vegan" scores higher, always
```

### Pluggable Embeddings (Optional)

```python
from aura import Aura

brain = Aura("./data")

# Plug in any embedding function: OpenAI, Ollama, sentence-transformers, etc.
from sentence_transformers import SentenceTransformer
model = SentenceTransformer("all-MiniLM-L6-v2")
brain.set_embedding_fn(lambda text: model.encode(text).tolist())

# Now "login problems" matches "Authentication failed" via semantic similarity
brain.store("Authentication failed for user admin")
results = brain.recall_structured("login problems", top_k=5)
```

Without embeddings, Aura continues to use its local recall pipeline - still fast, still effective.

### Encryption

```python
brain = Aura("./secret_data", password="my-secure-password")
brain.store("Top secret information")
assert brain.is_encrypted()  # ChaCha20-Poly1305 + Argon2id
```

### Semantic Memory Types

```python
brain = Aura("./data")

# Decisions are treated as higher-value memory
brain.store("Use PostgreSQL over MySQL", semantic_type="decision", tags=["db"])

# Preferences persist longer than generic working notes
brain.store("User prefers dark mode", semantic_type="preference", tags=["ui"])

# Contradictions are preserved for conflict analysis
brain.store("User said vegan but ordered steak", semantic_type="contradiction")

# Search by semantic type
decisions = brain.search(semantic_type="decision")

# Cross-domain insights surface higher-level patterns
insights = brain.insights(phase=2)
# Example:
# [{'insight_type': 'preference_pattern', 'description': 'Preference cluster around ui', ...}]
```

### Namespace Isolation

```python
brain = Aura("./data")

brain.store("Real preference: dark mode", namespace="default")
brain.store("Test: user likes light mode", namespace="sandbox")

# Recall only sees "default" namespace — sandbox is invisible
results = brain.recall_structured("user preference", top_k=5)
```

## Cookbook: Personal Assistant That Remembers

The killer use case: an agent that remembers your preferences after a week offline, with zero API calls.

See [`examples/personal_assistant.py`](examples/personal_assistant.py) for the full runnable script.

```python
from aura import Aura, Level

brain = Aura("./assistant_memory")

# Day 1: User tells the agent about themselves
brain.store("User is vegan", level=Level.Identity, tags=["diet"])
brain.store("User loves jazz music", level=Level.Identity, tags=["music"])
brain.store("User works 10am-6pm", level=Level.Identity, tags=["schedule"])
brain.store("Discuss quarterly report tomorrow", level=Level.Working, tags=["task"])

# Simulate a week passing — run maintenance cycles
for _ in range(7):
    brain.run_maintenance()  # decay + reflect + consolidate + archive

# Day 8: What does the agent remember?
context = brain.recall("user preferences and personality")
# -> Still remembers: vegan, jazz, schedule (Identity, strength ~0.93)
# -> "quarterly report" decayed heavily (Working, strength ~0.21)
```

Identity persists. Tasks fade. Important patterns get promoted. Like a real brain.

## MCP Server (Claude Desktop)

Give Claude persistent memory across conversations:

```bash
pip install aura-memory
```

Add to Claude Desktop config (Settings → Developer → Edit Config):

```json
{
  "mcpServers": {
    "aura": {
      "command": "python",
      "args": ["-m", "aura", "mcp", "C:\\Users\\YOUR_NAME\\aura_brain"]
    }
  }
}
```

Provides 8 tools: `recall`, `recall_structured`, `store`, `store_code`, `store_decision`, `search`, `insights` (with phase filtering), `consolidate`. Store and search support `semantic_type` filtering.

## Architecture

Aura uses a Rust core with Python bindings and a local-first memory runtime.

Publicly documented concepts are:

- Two-tier memory: cognitive + core
- Semantic roles for records
- Local multi-signal recall
- Trust, provenance, and namespace isolation
- Maintenance, insights, consolidation, and versioning

The public repository documents the user-facing behavior and integration surface. Detailed internal architecture, tuning, and research notes are intentionally not published.
