Build Agents That Continuously Learn & Adapt

As users interact with your agent and business, Zep integrates new knowledge, marks outdated facts as invalid, tracks changes, and retains history—enabling agents to reason about evolving user states.

More Than Just Conversational Memory

One User Record from Chat and Business Data

Ensure your agent always has accurate context. Zep fuses chat and business data into a unified Knowledge Graph, accessible through a single API call.

Add Agent Memory in Minutes

With minimal code changes, enable your agent with rich, relevant context from chat and business data.

example.py
# Add a chat message to the graph
await zep_client.memory.add(session_id, messages=[
    Message(role="Jane", role_type="user", content="I can't log in!")
])
# Add business data to the graph
await zep_client.graph.add(user_id=user_id, type="json", data={"account_status": "suspended"})

# get memory relevant to the current conversation
memory = zep_client.memory.get(session_id="session_id")
print(memory.context)

"""FACTS and ENTITIES represent relevant context to the current conversation.
# These are the most relevant facts and their valid date ranges
# format: FACT (Date range: from - to)
