A friendship book for grown-ups (and kids)

Growing up, many of us had a notebook we called a lexicon — or a friendship book, slam book, Poesiealbum, carnet d'amitié, vriendenboekje. It held the same kind of questions: your full name, your birthday, your favourite song, do you have a crush? We passed it around the classroom and got it back full of handwriting, doodles, and little secrets. Lexiconaut is that notebook, reborn as a free web app. Add open-ended questions, this-or-that picks, and tournament brackets. Share a link. Get answers back in words, drawings, photos, and GIFs. For friends, families, couples, classmates, teams, party guests — for anyone who still loves a good question.

How It Works

Create a Lexicon

Build your own questionnaire by mixing and matching three types of sections: open-ended questions, "Pick a Side" pairs, and tournament brackets.

Share It

Send a simple link to your friends, family, coworkers, or anyone you'd like to know better.

Read the Answers

Browse responses question by question or person by person. Laugh, learn, and connect.

Why We Built This

We built Lexiconaut because the ritual of filling out someone's lexicon is one of the simplest, kindest ways to get to know another person. It doesn't feel like a survey. It feels like a gift.

A paper notebook worked beautifully in one classroom. A web app works across cities, borders, and generations. Your grandmother can answer the same lexicon your niece made — and both of them can reply in their own language, with a drawing or an emoji if words aren't enough.
