This tutorial builds on [Add tools](./2-add-tools.md).
## 1. Create a `MemorySaver` checkpointer
## 1. Create a `InMemorySaver` checkpointer
Create a `MemorySaver` checkpointer:
Create a `InMemorySaver` checkpointer:
``` python
from langgraph.checkpoint.memory import MemorySaver
from langgraph.checkpoint.memory import InMemorySaver
memory = MemorySaver()
memory = InMemorySaver()
```
This is in-memory checkpointer, which is convenient for the tutorial. However, in a production application, you would likely change this to use `SqliteSaver` or `PostgresSaver` and connect a database.
