NeuralMemory

Your AI agent forgets everything between sessions. Neural Memory gives it a brain.

·

·

Memories are stored as interconnected neurons and recalled through spreading activation — the same way the human brain works. No vector database. No API calls. No monthly embedding bill.

pip install neural-memory

Restart your AI tool. Your agent now remembers — no `init` needed, the MCP server auto-initializes on first use.

Already installed? `nmem update` upgrades in place and detects whether you installed via pip or from source. `nmem update --check` only reports what is available.

> The CLI is `nmem` (or the longer `neural-memory`). There is no `nm` binary.

3 Tools. That's It.

63 MCP tools are available, but you only need three:

Everything else — sessions, context loading, habit tracking, maintenance — works transparently in the background.

What Makes This Different

Most memory tools are search engines. Neural Memory is a graph that thinks.

When you ask "Why did Tuesday's outage happen?", a vector database returns the most similar sentence. Neural Memory traces the chain:

outage ← CAUSED_BY ← JWT expiry ← SUGGESTED_BY ← Alice's review

Relationships are explicit — `CAUSED_BY`, `LEADS_TO`, `RESOLVED_BY`, `CONTRADICTS` — so your agent doesn't just find memories, it *reasons* through them.

Cloud Sync — Your Data, Your Infrastructure

Sync your brain across every machine. Unlike other memory tools, we never store your data.

Laptop ←→ Your Cloudflare Worker ←→ Desktop
                  ↕
              Your Phone

You deploy the sync hub to your own Cloudflare account (free tier). Your D1 database, your encryption key, your data. We provide the code — you own the infrastructure.

nmem sync              # push/pull changes
nmem sync --auto       # auto-sync after every remember/recall

Sync uses Merkle delta — only diffs travel, not the full brain. Fast, efficient, private.

Features

Memory & Recall

• 14 memory types — fact, decision, error, insight, preference, workflow, instruction, and more
• Spreading activation — memories surface by association, not keyword match
• Cognitive reasoning — hypothesize, submit evidence, make predictions, verify with Bayesian confidence
• Workload presets — `nmem config preset {balanced,safe-cost,max-recall,chat-heavy}` tune the brain for SaaS, frugal mode, deep retention, or conversational agents
• Temporal recall — `nmem_causal` exposes `temporal_range` and `temporal_neighborhood` actions; see the Temporal Recall Recipes guide

Knowledge Ingestion

• Train from documents — PDF, DOCX, PPTX, HTML, JSON, XLSX, CSV ingested into permanent brain knowledge
• Import adapters — migrate from ChromaDB, Mem0, Cognee, Graphiti, LlamaIndex in one command

Lifecycle & Storage

• Memory consolidation — episodic memories mature into semantic knowledge over time
• Compression tiers — full → summary → essence → ghost → metadata (reclaim storage, keep meaning)
• Brain versioning — snapshot, rollback, diff, transplant memories between brains

Community

• Brain Store — browse, import, and publish pre-built brains to the community marketplace
• 3 seed brains — Python Best Practices, Git Workflows, Docker Essentials (ready to import)

Ecosystem

• Web dashboard — 7-page React UI with graph visualization, health radar, timeline, mindmap, Brain Store
• VS Code extension — memory tree, graph explorer, CodeLens, WebSocket sync (Marketplace →)
• Safety — Fernet encryption, sensitive content auto-detection, parameterized SQL, path validation
• Telegram backup — send brain `.db` files to Telegram for offsite backup

Quick Examples

# Store memories (type auto-detected)
nmem remember "Fixed auth bug with null check in login.py:42"
nmem remember "We decided to use PostgreSQL" --type decision
nmem todo "Review PR #123" --priority 7

# Recall
nmem recall "auth bug"
nmem recall "database decision" --depth 2

# Brain management
nmem brain list && nmem brain health
nmem brain export -o backup.json

# Sync across devices
nmem sync --full

# Web dashboard
nmem serve    # http://localhost:8000/dashboard

Neural Memory Pro

Free Neural Memory is complete — 63 tools, unlimited memories, fully offline. You never have to pay.

But past 10K memories, things change. Keyword matching misses semantically related content. Consolidation slows to minutes. Storage grows unbounded. If your agent's brain is getting big, Pro makes it smart.

Free recalls by keyword. Pro recalls by meaning.

Query: "authentication improvements"

Free (FTS5):  2 results — exact matches only
Pro  (HNSW):  7 results — includes "JWT rotation", "session hardening", "OAuth migration"

What Pro adds

Setup by Tool

Claude Code (Plugin)

/plugin marketplace add nhadaututtheky/neural-memory
/plugin install neural-memory@neural-memory-marketplace

Cursor / Windsurf / Other MCP Clients

pip install neural-memory

Add to your editor's MCP config:

{
  "mcpServers": {
    "neural-memory": { "command": "nmem-mcp" }
  }
}

OpenClaw (Skill or Plugin)

Skill — one click via ClawHub. Published on every release:

clawhub.ai/skills/neural-memory

Plugin — memory slot replacement. Use this if you want NeuralMemory to *be*

OpenClaw's memory provider rather than a skill it calls:

pip install neural-memory && npm install -g neuralmemory

Set memory slot in `~/.openclaw/openclaw.json`:

{ "plugins": { "slots": { "memory": "neuralmemory" } } }

Upgrade to Pro

Already using Neural Memory? Just activate your key:

nmem shared activate --key NM-PRO-XXXX-XXXX-XXXX   # activate license

Then enable InfinityDB (semantic search engine):

# ~/.neuralmemory/config.toml
storage_backend = "infinitydb"

Restart your MCP server. Existing memories are auto-migrated from SQLite to InfinityDB on first startup.
