Origin story

Nuit de charrette — the night of the cart.

The name comes from a ritual at the École des Beaux-Arts in 19th-century Paris: weeks of work on an architectural project, finished in one impossible final night. We built Nuit for that moment — when a brief has to become something you can point to by morning.

En charrette: on the cart, still working, running out of time.

A name borrowed from architecture school. In late 19th-century Paris, students at the École des Beaux-Arts worked for weeks on architectural projects and finished them all in one final, impossible night. At dawn, runners arrived with wooden handcarts — charrettes — to collect the drawings and carry them to the jury.

Frantic to add the last lines before the deadline, students would climb onto the carts and keep drawing as the horses pulled them through the cobblestone streets. That was the original meaning of en charrette: on the cart, still working, out of time. The word entered the architectural vocabulary and never left.

The all-nighter was a ritual, not a punishment. The charrette wasn't only about deadlines — it was the moment the abstract became an object. A brief, a program, a set of constraints, finally made real. Architects who lived through it talk about it the way musicians talk about late-night studio sessions.

Working against time, against sleep, against your own doubts, made the work sharper. The charrette was where you stopped thinking and started deciding.

The word travelled. By the 1960s it had crossed into American architecture programs; by the 1990s the “design charrette” had become a standard practice in urban planning worldwide. The tool changed, but the feeling it named stayed exactly the same.

Today the charrette looks different. The handcart is a browser tab. The oil lamp is a laptop screen. The jury is a client meeting at 9 AM. But the shape of the night is identical: you have a brief, you have until morning, and by then an idea has to exist in the world as something you can point to.

We built the tool we wish we had at 4 AM.

For the moment when you stop sketching and start deciding — when a brief has to become a visual, fast, and the cost of a wrong direction can't be a whole night wasted. Nuit is built for the concept phase: the fast, exploratory stage where a project finds its direction.
