Custom knowledge sources no longer have to be written one article at a time. Drop in documents and Handhold turns them into searchable content your agents can use.

- **Use the files you already have.** Upload PDF, Word, Markdown or plain-text documents.
- **Bring over several at once.** Drag files anywhere onto the upload area and Handhold works through them two at a time.
- **Keep the source close.** The original file stays attached to the article, so you can review the extracted content or download the document later.
