Inspiration

WhatsApp is an ubiquitous program that everyone uses. However, unlike competitors like Telegram, it does not have an API for personal accounts, which limits the use of the application to solely communication via calls or messaging. Considering the growth of smart assistances and chatbots in other mediums, we were looking to offer similar functions to something we use very often - WhatsApp.

What it does

wa++ is a library that allows programs to interact with users via WhatsApp. wa++ enables you to turn your personal WhatsApp account into a chatbot, whose program you can either use current pre-added functionalities or you can build your own simply. The possibilities are limitless - listed below are examples of functionalities we have pre-added into the software.

for Self:

Auto reply to specific messages (when you are in DnD mode)
Set personal reminders that will message you during set time
Answer your personal questions, regarding weather, general knowledge etc.
Journal your day by conversing with a bot
Support your health - log diet, exercise, set medication reminders etc.

for Groups:

Set group reminders for specific friends
Search for past information covered in past discussions
Targeted messaging - send to specific members within the group chat
Time management bot - set alarms for specific task
Mathematical tools - quick calculation
Discussion note taking bot

for Fun:

Solve individual puzzles e.g. guess the number, hangman
Play group based games like Werewolf and Avalon
Spam your friends quickly and effortlessly
Returns the message you just sent
Bot that randomly sends nonsensical gibberish to you
Joke telling bot

How we built it

We used Python and a framework called Selenium to automate the browser interaction for Whatsapp Web. First, we wrote the API functions that our bots would be built on, such as sending and receiving messages. After ensuring that these functions worked as intended, we then proceeded to build some simple bots to demonstrate the API, such as an auto-reply bot and games like hangman and guess the number. We also tried to get as many friends as possible to test our bots, to make sure they worked properly.
