Meet Bo

Bo is the bear who keeps you company while you learn.

He turns up at the edges of the work — the deck you haven't filled yet, the session you have just finished, the morning you open Langu with nothing started — and stays out of the middle of it. You will never meet him on a card you are trying to answer. He has six expressions and one job: to say something true about where you are, and then get out of the way.

Why a bear

Langu is built out of the things you get wrong. Every word you miss goes into your mistake journal, comes back on the day you are about to forget it, and turns into the next thing you study. That is a good way to learn a language and an uncomfortable thing to look at: a list of your own errors, getting longer.

Bo is how that list gets read back to you. He names the mistake and moves on. There is no scolding when you skip a day and no fanfare when you don't, because neither of those is information — and a bear who celebrated everything would mean nothing when you had actually done something hard. He is asleep when there is nothing to read, and waving when you arrive.

Where you'll meet him

Bo At the top of every screen, shrunk to the mark beside the wordmark. That build is three shapes: below 28px a face turns to mud, so the design system draws a heavier one.

Bo is thinking While a card, a quiz or an explanation is being written for you. He is waiting exactly as long as you are.

Bo is celebrating At the end of a study session, once, next to what you actually did. He is the ceiling of the celebration, not the start of it.

Bo is being encouraging Straight after a card you got wrong, beside the answer and the reason. This is the expression the whole character is for.

Bo is asleep On a screen with nothing on it yet. You are not behind — there is genuinely nothing here to read, and he is not going to invent something.

Bo is waving The first time you open Langu, on the sign-in screens, and here.
