Celiums

Your AI doesn't know what it doesn't know. And it forgets everything.

The open-source engine that gives AI persistent memory and instant access to 5,100+ expert knowledge modules — with a biological clock that adapts to each user.

The Problem

Every time your AI assistant starts a new session, it starts from zero. It doesn't remember your preferences, your project decisions, your debugging history, or what you were working on yesterday. It hallucinates because it has no specialized knowledge — just general training data frozen at a cutoff date.

You spend more time re-explaining context than getting work done.

The Solution

Celiums combines two engines into one:

Engine	What it does	How
Memory	Remembers everything — with emotion	PAD vectors, dopamine, circadian rhythm, 15 cognitive modules
Knowledge	Knows what experts know	5,100 curated technical modules, full-text search, 18 categories

Both engines expose 6 MCP tools that any AI IDE can call autonomously. Install once, your AI has persistent memory AND expert knowledge forever.

See it in action: ask.celiums.ai

Talk to Celiums AI directly — it uses all 5,100 modules, remembers you across sessions, and has a real circadian rhythm. Zero-knowledge: your data is never used for training.

Quick Start

Option 1: npm (local, 60 seconds)

npm install -g @celiums/cli
celiums init

That's it. celiums init:

• Asks your name, timezone, and if you're a morning or night person
• Loads 5,100 expert knowledge modules
• Auto-configures Claude Code, Cursor, and VS Code
• Creates your personal cognitive profile (circadian rhythm adapts to YOU)

Option 2: Docker (VPS, 3 minutes)

# 1. Clone
git clone https://github.com/terrizoaguimor/celiums-memory.git
cd celiums-memory

# 2. Configure
cp .env.example .env   # edit passwords

# 3. Start infrastructure (PostgreSQL + Qdrant + Valkey)
docker compose up -d

# 4. Install dependencies
pnpm install

# 5. Build + start Celiums
pnpm setup

You get: Celiums API on port 3210 + PostgreSQL + Qdrant + Valkey. On first run, 5,100 expert modules are loaded automatically.

Option 3: DigitalOcean 1-Click (coming soon)

One button. Deploys everything on your own DO droplet.

The 6 Tools

When connected via MCP, your AI can call these autonomously:

Knowledge tools (search 5,100 expert modules)

Tool	What it does	Example
forage	Search for expert knowledge	"find modules about Kubernetes security"
absorb	Load a specific module	"load the react-server-components module"
sense	Get recommendations for a goal	"what should I use for building a REST API?"
map_network	Browse all categories	"show me what knowledge areas are covered"

Memory tools (persistent emotional memory)

Tool	What it does	Example
remember	Store something in memory	"remember that we chose Hono over Express"
recall	Retrieve by semantic relevance	"what framework decisions did we make?"

What happens behind remember (the user sees nothing, it just works):

User: "remember that we chose Hono over Express for the API"
                    |
          PAD Emotional Vector (pleasure: 0.4, arousal: 0.3, dominance: 0.5)
                    |
          Theory of Mind (empathy matrix transforms user emotion)
                    |
          Dopamine / Habituation (novelty detection, reward modulation)
                    |
          Per-User Circadian (your timezone, your peak hour, your rhythm)
                    |
          PFC Regulation (clamp safe bounds, suppress extremes)
                    |
          Triple-Store Persist (PostgreSQL + Qdrant + Valkey)
                    |
          "Remembered (importance: 0.72)"

15 cognitive systems fire on a single remember call. The user just types one sentence.

How to Use It

Connect to your IDE

After celiums init, it's auto-wired. Or manually:

Claude Code:

claude mcp add celiums -- celiums start --mcp

Cursor — add to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "celiums": { "command": "celiums", "args": ["start", "--mcp"] }
  }
}

VS Code — add to settings.json:

{
  "mcp.servers": {
    "celiums": { "type": "stdio", "command": "celiums", "args": ["start", "--mcp"] }
  }
}

Use the tools in conversation

Once connected, your AI uses the tools automatically. Just talk normally:

You: "Find me best practices for PostgreSQL optimization"
AI:  -> calls forage(query="PostgreSQL optimization")
     -> finds postgresql-best-practices-v2 (eval: 4.0)
     -> presents the expert module content

You: "Remember that we decided to use JSONB for metadata columns"
AI:  -> calls remember(content="decided to use JSONB for metadata columns")
     -> stored with importance 0.68, mood: focused

You: "What database decisions have we made?"
AI:  -> calls recall(query="database decisions")
     -> finds: "decided to use JSONB for metadata" (score: 0.89)
     -> presents with emotional context

REST API

If running as a server (Docker/VPS), the full API is available:

# Search modules
curl http://localhost:3210/v1/modules?q=react+hooks

# Get a specific module
curl http://localhost:3210/v1/modules/typescript-mastery

# Browse categories
curl http://localhost:3210/v1/categories

# Store a memory
curl -X POST http://localhost:3210/store \
  -H "Content-Type: application/json" \
  -d '{"content": "The API uses Hono framework", "userId": "dev1"}'

# Recall memories
curl -X POST http://localhost:3210/recall \
  -H "Content-Type: application/json" \
  -d '{"query": "what framework", "userId": "dev1"}'

# Check your circadian rhythm
curl http://localhost:3210/circadian?userId=dev1

# Update your timezone
curl -X PUT http://localhost:3210/profile \
  -H "Content-Type: application/json" \
  -d '{"userId": "dev1", "timezoneIana": "Asia/Tokyo", "timezoneOffset": 9}'

# MCP protocol (for AI clients)

Per-User Circadian Rhythm

Each user gets their own biological clock:

curl http://localhost:3210/circadian?userId=dev1
# {
#   "localHour": 10.5,
#   "rhythmComponent": 0.99,
#   "timeOfDay": "morning-peak",
#   "circadianContribution": 0.30
# }

A user in Tokyo gets different arousal than a user in New York at the same moment.

Security

• Local-first. Your memories live ONLY on your machine or your own server. Nothing is sent to us.
• API key auth. Bearer token required for all non-localhost requests.
• Per-user isolation. Each user has their own memory space, emotional state, and circadian profile.
• No telemetry. Zero analytics, zero tracking, zero phone-home.
