Show HN: QuizBuds – weekly team trivia inside Slack (feedback wanted)

https://quizbuds.app
1•sanilnz•1h ago
Hi HN,

We’re Sanil and Kyle, building QuizBuds, a simple quiz app that runs inside Slack.

We built it to help people who don’t usually interact have a quick, low-stakes reason to connect. We aim for questions that are light-hearted and easy to jump into (still improving this).

How it works: at the start of each week, QuizBuds uses a central channel to form teams. Trivia is posted in private team channels, teams have 15 minutes to answer, and results are posted back to the central channel. Teams rotate weekly, and we run a lightweight 4-week season leaderboard.

We’re early, and feedback matters more than growth. If you try it, blunt feedback would really help on: - setup/install friction - whether the experience feels fun or noisy - question quality - what would make this genuinely useful for your team - anything else, :send-it:

It’s free to start with a 2-month trial (no CC) at https://quizbuds.app, and we’ll be active in the thread.
