Personal AI memory — gives every AI agent shared, persistent memory of you
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.
git clone https://github.com/gunning4it/epitome.git
cd epitome
cp .env.example .env # edit with your credentials
docker compose up -dOpen localhost:5173 and sign in with Google or GitHub OAuth.
Get your API key from Settings → API Keys in the dashboard (hosted or self-hosted).
Add to your claude_desktop_config.json:
{
"mcpServers": {
"epitome": {
"url": "https://epitome.fyi/mcp",
"headers": {
"Authorization": "Bearer YOUR_API_KEY"
}
}
}
}claude mcp add --transport http --header "Authorization: Bearer YOUR_API_KEY" epitome https://epitome.fyi/mcpFor self-hosted, replace https://epitome.fyi with http://localhost:3000.
Epitome exposes 3 MCP tools — recall, memorize, and review. See the full tool reference.
| Chat History | Vector DB | Note Apps | Epitome | |
|---|---|---|---|---|
| Portable identity | ✓ | |||
| Multi-agent shared memory | ✓ | |||
| Knowledge graph | ✓ | |||
| Consent & audit per agent | ✓ | |||
| Per-user schema isolation | ✓ | |||
| Structured + semantic data | partial | ✓ | ||
| Self-hostable | ✓ | ✓ |
| # | 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. |

per-user schema
isolationEach 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.
