Quizper

Quizper positions itself around variety and team play: its own tagline promises trivia you can play "alone or with a team," across a spread of topics that reportedly includes science, film, history and technology among others. Rather than a single endless question stream, the format leans toward discrete quizzes you can start and finish, making it easier to fit a session into a short break.

Group-chat support is one of its stated strengths, letting a team work through questions together rather than every player racing individually — a different social dynamic from bots where the fastest single answer wins. That makes it a reasonable option for a group that wants to solve trivia collaboratively rather than compete head-to-head.

Its own profile description is in Russian, and detailed usage information beyond that is limited, so treat the exact category list and scoring mechanics as things to confirm by trying it rather than settled facts; there is no visible monthly-user count on its public page.
