My idea is basically a WhatsApp event reminder, where users add events on the website (which has a very simple interface) and they can put the event name, a description, the time of the event, and they can also upload files. Once uploaded, when the time of the event comes, the bot will send a message to the WhatsApp number registered with a reminder of the event and the information provided.
And if you have the premium version, you could just chat with the bot explaining the event and it will remind you when the time comes.
What do you think? I want your honest opinion, please, it would be so much help for me as I would not waste my time if it's not a good idea. Thanks for reading!
