I am assuming you are calling openai API - which requires to pay based on tokens. Whats your business model since all the users are unpaid users?

Do you maintain the costs from ADs? Do you charge users?

Thank you

I'm just exploring whether or not it's useful. If people continue using it and/or it evolves into something more useful, I'll likely charge a monthly fee for access to certain features (e.g. longer pdfs, merging multiple pdfs into one bot, having multiple bots). The plan is to keep it partially free though

Got it. Thank you Currently is there any limit on the pdf sizes or number of pages to upload. For example, if I upload my entire book pdf (500pages), it will cost you a lot.

From your tweet, I saw you now support 2x file size limit (300 → 600 pgs). I am assuming its costing a lot for the free trial. Best of Luck :)
