Epitome

One memory layer, every AI agent.

The portable identity layer that gives every AI agent a shared, persistent memory of you.
Open source. Self-hostable. Yours.

The Problem

Every AI conversation starts from zero. You repeat yourself to every agent — your name, your preferences, your allergies, your tech stack. Chat history is siloed per app. There's no portable memory layer.

Epitome fixes this. One database that every AI agent shares, so they all remember you.

Quickstart

Hosted (fastest)

1. Sign up at epitome.fyi
2. Go to Settings → API Keys and copy your MCP URL
3. Connect an AI agent — done

Self-Hosted

git clone https://github.com/gunning4it/epitome.git
cd epitome
cp .env.example .env    # edit with your credentials
docker compose up -d

Open localhost:5173 and sign in with Google or GitHub OAuth.

Connect an AI Agent

Get your API key from Settings → API Keys in the dashboard (hosted or self-hosted).

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "epitome": {
      "url": "https://epitome.fyi/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Claude Code

claude mcp add --transport http --header "Authorization: Bearer YOUR_API_KEY" epitome https://epitome.fyi/mcp

Self-Hosted

For self-hosted, replace https://epitome.fyi with http://localhost:3000.

Epitome exposes 3 MCP tools — recall, memorize, and review. See the full tool reference.

Who This Is For

• AI developers building agents that need persistent user memory
• Power users who want every AI to remember them across platforms
• Self-hosters who want full data ownership — no cloud required

Use Cases

• Your meal-tracking agent remembers your allergies
• Your coding assistant knows your stack, your patterns, your team
• Your calendar agent knows your family, your priorities, your routines
• Every new AI tool you try already knows you on day one

The Five Layers

#	Layer	Description
01	Personal Database	Structured tables, vector semantic memory, and key-value storage. Your data lives in PostgreSQL — queryable, exportable, yours.
02	Portable Identity	A structured profile any AI agent reads instantly. Name, preferences, relationships — zero cold start, every conversation.
03	Memory Quality	Confidence scoring, source attribution, and lifecycle management. Memories earn trust through reinforcement, not blind faith.
04	Knowledge Graph	Entities with typed, weighted edges. People, places, concepts — connected in a graph that grows with every interaction.
05	Consent & Audit	Per-table permissions and an append-only activity log. You control exactly what each agent can see and do.

Architecture

AI Agent ──→ MCP (Streamable HTTP) ──→ Hono API ──→ PostgreSQL
                                         │
                                    per-user schema
                                      isolation

Each user gets their own PostgreSQL schema (user_{id}) — not row-level security, full schema-level isolation. Cross-schema access is impossible at the SQL level.

See EPITOME_TECH_SPEC.md for the full architecture.

---

Security & Privacy

• You own your data — self-host or use the hosted service
• Per-user PostgreSQL schema isolation — not row-level security, full schema separation
• Per-agent consent rules — you control what each agent can read and write
• Append-only audit log — every access is recorded
• GDPR-ready — export or delete all your data at any time
