Lantern is made for the person who opens the link. They get a door with their name on it, and a memory of a place you shared.
You describe it.
A few sentences about a room. What it looked like, what was in it, what the light was doing.
The roof of the block of flats we grew up in, where we went to get away from everyone. Cracked concrete, a water tank, aerials, and the whole city going orange at six o’clock.
Lantern builds it.
World Labs’ Marble turns the description into a spatial world you enter at its strongest viewpoint. Tripo makes the objects that were in it, the water tank, the aerials, and sets them into the scene so they sit behind and in front of what’s already there.
You leave your voice in it.
Record a short note on any object. Your voice belongs to that remembered thing inside the room. Then send the link.
Places people have built for each other. Each one was made for someone by name.
