Sign up

  1. Go to app.3ngram.ai and create an account
  2. Complete onboarding to set up your workspace
Once signed in, you can use the dashboard to browse memories, commitments, and decisions. But the real power comes from connecting your AI tools.

​
Connect an MCP client

3ngram works through the Model Context Protocol (MCP). Connect any MCP-compatible AI tool to give it persistent memory across sessions. The fastest way to get started is with Claude Desktop:
  1. Open Claude Desktop settings
  2. Navigate to the MCP servers section
  3. Add 3ngram with your auth credentials:
{
  "mcpServers": {
    "3ngram": {
      "url": "https://mcp.3ngram.ai/mcp"
    }
  }
}
Claude Desktop will walk you through OAuth authorization on first connection. For other clients (Claude Code, Cursor, ChatGPT), see the Connecting Clients guide.

​
Save your first memory

With 3ngram connected, just ask your AI assistant to remember something:
“Remember that we chose PostgreSQL for the database”
3ngram stores it with the right type, project tag, and scope automatically. Try saving a commitment with a due date:
“Remember this commitment due Friday: finish the API review”

​
Recall memories

Ask naturally:
“What do you remember about the database decision?”
“What commitments do I have this week?”
“Show me my open blockers”
3ngram uses semantic search, so you don’t need exact keywords.

​
Run a briefing

Start your next session with a briefing to pick up where you left off:
“Run my briefing”
This gathers open commitments, blockers, overdue items, and recent decisions into a structured summary.
