# forget()

> Remove data with the unified v1.0 deletion API

# cognee.forget()

```python theme={null}
async def forget(
    *,
    data_id: Optional[UUID] = None,
    dataset: Optional[Union[str, UUID]] = None,
    everything: bool = False,
    memory_only: bool = False,
    user=None,
) -> dict
```

## Description

`forget()` is the unified deletion API in Cognee v1.0.

* Use it to remove a single data item from a dataset.
* Use it to delete an entire dataset.
* Use `everything=True` to remove all memory owned by the current user.
* Use `memory_only=True` to clear graph and vector memory while keeping raw dataset records so the content can be reprocessed.

For the full behavior walkthrough, see [Forget](/core-concepts/main-operations/forget).

## Parameters

<ParamField path="data_id" type="Optional[UUID]" default="None">
  Specific data item to remove. Requires `dataset` to also be set.
</ParamField>

<ParamField path="dataset" type="Optional[Union[str, UUID]]" default="None">
  Dataset name or UUID. When used alone, deletes the whole dataset. When paired with `data_id`, deletes only that item from the dataset.
</ParamField>

<ParamField path="everything" type="bool" default="False">
  Deletes all datasets and memory owned by the current user.
</ParamField>

<ParamField path="memory_only" type="bool" default="False">
  Deletes only graph and vector memory for the target dataset or data item while keeping underlying dataset records.
</ParamField>

<ParamField path="user" type="Any" default="None">
  Runs the operation under a specific user context instead of the default user.
</ParamField>

## Return value

`forget()` returns a summary dictionary. Depending on the mode, it includes fields like `status`, `dataset_id`, `data_id`, or `datasets_removed`.

## Examples

```python theme={null}
import cognee

# Delete a dataset
await cognee.forget(dataset="product_docs")

# Delete only graph and vector memory so the dataset can be re-cognified
await cognee.forget(dataset="product_docs", memory_only=True)
```
