A classic stranger roulette with filters that make matching a bit less random. Interest-based pairing is what many basic anonymous chats are missing. The bot speaks English, so expect people from all over.
There is a whole genre of bots where you press a button and get connected to a total stranger who cannot see your profile. TopStranger belongs to it but adds settings: you can specify age, gender and interests, and the bot tries to pair you with someone who matches.
The interests filter changes a lot. In plain roulette half the chats die after hi, where are you from, but when both people care about the same game or music, conversation starts faster. How many topics there are and whether filters cost anything is not visible from the profile.
Since everything runs in English, practicing the language with real people is very doable. Whether there is moderation, a report button or bans for abuse, the description does not say, though bots like this always let you end a chat and move on to the next one.
Your partners here are random, and whatever you share stays with them. Do not give out your phone number, address or workplace, and think twice before moving a chat to private messages with someone you met five minutes ago.
