# Forget Endpoint

> Remove data from the knowledge graph.

- Set `everything: true` to delete all user data.
- Set `dataset` alone to delete an entire dataset.
- Set `dataset` + `data_id` to delete a single item.
- Set `dataset` + `memory_only: true` to clear memory
  (graph + vector), preserving raw files so the dataset can be re-cognified.
- Set `dataset` + `data_id` + `memory_only: true` to clear memory
  for a single file only.
