Documents and PDFs
The chatbot can read the text inside the PDFs in your Media Library and link to them in answers.
Turn it on
Open Settings → Content
Find Documents under What the chatbot reads.
Tick the three boxes
Read documents in the Media Library, Documents only, not photos and other images and Read the text inside PDFs.
Save changes
New PDFs are read automatically when you upload them.
Reading status
Under the Documents options the settings page shows how many of your PDFs have text the chatbot can read, and how many are still waiting. To catch up a large library, click Read PDFs now: it reads a few straight away and the rest in the background.
Scanned PDFs
Scanned pages without a text layer cannot be read: they’re pictures of text. Re-save them with text recognition (OCR), which most scanner software and PDF editors offer, and upload the new file.
PDF text from
Leave PDF text from blank and the chatbot reads each PDF itself. That needs a common server tool called Ghostscript; if your host doesn’t have it, the settings page tells you. If another plugin already keeps each PDF’s text in a custom field, enter that field’s key here instead.
Finding PDFs by their contents
Turn on Let searches match the fields below and PDF text (Content → Search) so a question can find a PDF by what it says, not just by its title.
