About Guessbook

A trivia game about one person, played by the people who love them.

What it is

Guessbook is party trivia about a real person — the guest of honor at a baby shower, a birthday, a wedding, a retirement, a team night. The host answers a few questions about them (first pet, worst haircut, the thing they always order), we turn those into a game with believable wrong answers, and everyone plays on their own phone from a link. Nobody installs anything or makes an account to play. At the end there's a reveal: the answers, the room's split on each one, and a podium for whoever knew them best.

It works in the room, on a video call, or across a week of people playing whenever they get to it. The reveal can go on a TV if there is one. It doesn't need one.

What it isn't

It isn't a pub-quiz app or a classroom tool, and it isn't general knowledge. Every question is about the person — that is the whole point, and it's why the reveal lands the way it does. We'd rather do that one thing well than add a general trivia mode that does it worse.

Who makes it

Guessbook is made by Spanvor LLC, a small company in Austin, Texas. The same people build it, answer the email, and refund you if something goes wrong. Write to hello@guessbook.app — a person reads it.

A few things we decided early

  • Guests never need an account. A link and a first name. The host can sign in to keep their games; nobody else has to.
  • Answers stay hidden until the reveal. No page, link or payload gives them away early — not to a guest, not to a clever guest. That rule is enforced on the server, not just in the design.
  • The free game is a real game. Up to four players, as many Guessbooks as you like, no card. Paying opens the door to more people; it doesn't unlock the product.
  • Plain prices, plain refunds. One Guessbook for everyone is $19, and it's refundable until the reveal has run or the day of the event.
  • No trackers, no selling data. We keep what the game needs to run and delete what you ask us to. The privacy page says the same thing in more words.

Where to start

Play the sample to see what a guest sees, or make one — it takes about ten minutes, and you can try it before anyone else does.
