How visitors attach a file
- Select the attachment button beside the chat input.
- Choose one or more supported files.
- Wait until every file finishes uploading, then send the message.
- Remove a file before sending with the remove button on its preview.
Model compatibility
The attachment button only offers formats supported by the selected model. Models marked Vision can read images; models marked Files can read PDFs. The model picker shows these capabilities for every model.
If the attachment control is missing, choose a model with the required Vision or Files capability under Settings → General.
Privacy
Tell visitors not to upload secrets or regulated personal data unless your policies permit it. Uploaded chat files use temporary access links so Chatwith and the selected model can process the message.
