A **Token chunker** component is a text splitter that creates chunks by respecting a recommended maximum token length, using delimiters to ensure logical chunk breakpoints. It splits long texts into appropriately-sized, semantically related chunks.
A **Token chunker** component is optional, usually placed immediately after **Parser** or **Title chunker**.
## Configurations
### Recommended chunk size
The recommended maximum token limit for each created chunk. The **Token chunker** component creates chunks at specified delimiters. If this token limit is reached before a delimiter, a chunk is created at that point.
### Overlapped percent (%)
This defines the overlap percentage between chunks. An appropriate degree of overlap ensures semantic coherence without creating excessive, redundant tokens for the LLM.
- Default: 0
- Maximum: 30%
### Delimiters
Defaults to `\n`. Click the right-hand **Recycle bin** button to remove it, or click **+ Add** to add a delimiter.
The global variable name for the output of the **Token chunker** component, which can be referenced by subsequent components in the ingestion pipeline.
