Looking to validate an idea for whatsapp chat export to pdf and other format conversion

I had this idea for this when I had some legal dispute with a landlord and needed to provide detailed whatsapp chat messages, but when I exported them they were ugly and lacked context so I built this tool to try get the chats into a more clean and structured format in a pdf which would be shareable. I built a simple tool which I could upload the files to aws s3 then it would process it via aws lambda into a pdf format. I later then had seen on reddit that people were looking for this kind of tool so I decided to launch a basic MVP its evolved a bit since then I have created the full tool and started with content marketing.
