The app

A room for each friend. Lucy is in all of them.

Two Macs talk directly, encrypted end to end. Messages, notes, voice and photos stay between you, and Lucy answers from a memory of the whole room.

Memory you can read.

Lucy’s memory stays on your Mac, and her mind is a page you can open.

The room with Maya: the plan for Lisbon, a note Lucy started, and four images waiting for approval at about 16 cents on the asker’s own key

01

Ready when asked.

Lucy turns to whoever is talking. Ask her to write the note, plan the trip or make the images, and nothing that costs money happens until you say yes.

Lucy’s mind: what she saw, what she remembers, why it came up and her upkeep, for a room with Maya

02

Her mind, open.

Every answer shows its reasons: what she saw, what she kept and why. Her upkeep runs once a night, on your key, and you can switch it off.

Since you were away: Lucy read two rooms, Maya’s trip to Lisbon and Theo’s photos, with the one question that needs an answer

03

Since you were away.

Come back to a few lines per friend, and the one message that needs you.

A table of everything that leaves the Mac, where it goes and who can read it: messages go to your friend’s Mac directly, end to end encrypted
