Key Differences

Zep AISupermemory
Sessions & MessagesDocuments & Container Tags
session.create()Use containerTags parameter
memory.add(session_id, ...)add({containerTag: [...]})
memory.search(session_id, {text: ...})search.execute({q: ..., containerTags: [...]})

​
Installation

pip install supermemory

from supermemory import Supermemory
client = Supermemory(api_key="your-api-key")

​
API Mapping

​
Session Management

session = client.session.create(
    session_id="user_123",
    user_id="user_123"
)

​
Adding Memories

client.memory.add(
    session_id="user_123",
    memory={"content": "User prefers dark mode"}
)

​
Searching

results = client.memory.search(
    session_id="user_123",
    search_payload={"text": "preferences", "limit": 5}
)

​
Getting All Memories

memories = client.memory.get(session_id="user_123")

​
Migration Steps

  1. Replace client initialization - Use Supermemory client instead of Zep
  2. Map sessions to container tags - Replace session_id="user_123" with containerTag: ["user_123"]
  3. Update method calls - Use add() and search.execute() instead of memory.add() and memory.search()
  4. Change search parameter - Use q instead of text
  5. Handle async processing - Documents process asynchronously (status: queued → done)

​
Complete Example

from zep_python import ZepClient

client = ZepClient(api_key="...")
session = client.session.create(session_id="user_123", user_id="user_123")

client.memory.add("user_123", {
    "content": "I love Python",
    "role": "user"
})

results = client.memory.search("user_123", {
    "text": "programming",
    "limit": 3
})

​
Important Notes

  • No session creation needed - Just use containerTag in requests
  • Messages are documents - Store with metadata.role and metadata.type
  • Async processing - Documents may take a moment to be searchable
  • Response structure - Supermemory returns chunks with scores, not direct memory content

Migrating Existing Data

​
Quick Migration (All-in-One)

Complete migration in one script: 
import { ZepClient } from "@getzep/zep-js";
import { Supermemory } from "supermemory";

// Initialize clients
const zep = new ZepClient({ apiKey: "your_zep_api_key" });
const supermemory = new Supermemory({ apiKey: "your_supermemory_api_key" });

// Export from Zep and import to Supermemory
const sessionIds = ["session_1", "session_2"]; // Add your session IDs

for (const sessionId of sessionIds) {
  const memory = await zep.memory.get(sessionId);
  const memories = memory?.memories || [];

  for (const mem of memories) {
    if (mem.content) {
      await supermemory.add({
        content: mem.content,
        containerTag: [`session_${sessionId}`, `user_${memory.user_id || "unknown"}`],
        metadata: {
          role: mem.role,
          type: "message",
          original_uuid: mem.uuid,
          ...mem.metadata
        }
      });
      console.log(`✅ Imported: ${mem.content.substring(0, 50)}...`);
    }
  }
}

console.log("Migration complete!");

Full Migration Script
