About

This application consists of a contextual chatbot on top of webpages modelled on Groww. The chatbot displays FAQs and information based on an investor’s current context on the website, by making use of the user's context consisting of user's id, category of choice (Stocks, Mutual Funds, Gold, FDs), web page selection (product or order pages), and other information to help the investor have a smooth & interactive browsing experience.

Contextual Responses

• As an example, let's take a non-KYC user whose My Account looks like this:

• The chatbot on a product page will show user's KYC status related FAQs in addition to product FAQs

• The chatbot on My Orders page will show FAQs relevant to the user's orders

• The chatbot on product pages also shows FAQs relevant to order status, if the user has any order history for that product
