Read File

The Read File component reads and processes uploaded files within a flow. Agentlab extends the standard Langflow component in two distinct ways:

  • Document Extraction — the component can delegate processing to the KARLI extraction service via an extraction backend dropdown. See Document Extraction.
  • Upload Targets — the component can be turned into a user-facing upload slot in the Karli Studio chat. Multiple Read File components in a flow can be configured this way to expose distinct upload buckets. See Upload Targets.

The two extensions are independent: a flow can use either, both, or neither.

Basic Usage

Drag the Read File component onto the canvas. With default settings it behaves identically to the upstream Langflow component — read file contents and pass them downstream as text.
