Hello There,
The basic funda of your requirement is very clear to me that you want me to create a chat interface for students and teachers. Here for chat, we have to use Comet chat SDK.
You already have your existing website and want me to add those functionalities to your existing system.
Need to manage admin, user module, student mapping module, conventional module, etc.
The message will receive text, basic formatting (Bold, italic, underline, line breaks), links, images, GIFs, emojis, videos, documents (PDF only), etc.
Need to make similar functionalities to Whatsapp.
Ready to work on your requirement. Please ping me over to the chat and let's continue.
Thank you,
Mahima
