Who you will be writing to
Galileo was born in Pisa in 1564. When he turned an improved telescope to the night sky, he found moons circling Jupiter and mountains on our own Moon, and he insisted on publishing in plain Italian so ordinary readers could follow along.
His discoveries brought him fame and, eventually, trial and house arrest. He kept working anyway, and he treasured the letters that reached him in confinement. He knows exactly what a good letter is worth.

Is each letter written by a person or by AI? A bit of both, and we're glad to be clear about it. Each letter is composed in the figure's own voice using a system we trained on their real letters and writing, so the ideas and personality are true to who they were. Then a real person reviews and refines every letter before it goes out. The result is original and personal, never pulled off a shelf.
