I want to automate asking GPT4 to analyse articles/research papers. The goal is to post a URL or PDF attachment in Discord, and get the ChatGPT analysis as a message in the same channel. The Zap looks like this:

Discord Msg Trigger → extract text from article in message → ChatGPT Conversation (analysis) → post analysis in Discord

Discord message input/output setup has been fine; the roadblock I’m experiencing is getting the bulk text of the article to pass to ChatGPT. I am a free user, so webhooks are not an option for me currently.

Options I have explored are as follows:

• PDF handler apps: the ones available seem to be for PDF generation only or extracting data from predictable templates e.g. invoices, so not suitable.
• Web Parser: can’t handle the amount of text I want to extract as it seems designed for normal webpages.
• Webhooks: premium option.

Can I do something with Google Docs acting as a “middle man” for this Zap, or are webhooks my only solution?
