An idea is following: you add a bot to the chat, it starts collecting word frequency statistics from conversation between users and then it will be able to generate list of topics that were discussed. It looks like: you open Telegram application, see 500+ unread messages at some chat, but you don't want to read it all. Then you just use command '/topics' and see what has discussed today.
