Input Blocks

Use input blocks to request content from users when the workflow runs. Inputs can be optional or required, and some can collect a batch (list) of items.

Available blocks:

  • User Text Input: prompts for a text string or a list of strings.
  • User Image Input: lets users upload one or more images.
  • User Audio Input: lets users upload one or more audio files.
  • User Video Input: lets users upload one or more videos.

How to use:

  1. Add the input block to your canvas.
  2. Configure its label and whether the input is required.
  3. If you expect multiple items, enable batching. The output becomes a list.
  4. Connect the block’s output to downstream blocks of the same modality.

Known constraints:

  • Modality must match the target input (text → text, image → image, etc.).
  • If batching is enabled, connect only to inputs that accept lists.
  • Media uploads must meet allowed size and type limits.
  • During testing, you’ll be prompted to type or upload the required content.
