About this app

A 7-character message just for the two of you.

tsuu is a messaging app where you exchange words with that special someone using only "7 characters."

No emojis, no images, no URLs. Just 7 characters.

"Constraints become value," "Simplicity becomes depth."

Born from this philosophy, it's the quietest messenger in the world.

— For you if—
• You want to cherish words more with your partner or best friend.
• You want to regain tranquility from social media fatigue.
• You want to leave behind genuine words without relying on emojis.

— Features of tsuu—
◆ 7-character limit
All messages are limited to 7 characters. Shortness gives weight to the words.

◆ A space just for the two of you
Exclusively for 1-on-1 pairs connected by an invitation code. No groups, no unspecified users.

◆ 7-second delete right
Within 7 seconds of sending, you can erase it. Mistakes, doubts—you can delete them.

◆ 777 Message Haiku
When two people exchange 777 messages, AI creates a unique haiku just for the two of you.
A one-of-a-kind memento born from your words.

◆ The Aesthetics of Subtraction
A palette of seven colors, with whitespace arranged in multiples of seven. A space where the Japanese concept of "ma" (space/interval) and the tranquility of France blend together.

— For these occasions —
・As a signal in the midst of busy days
・As a secret code between you and your lover
・As a short prayer for someone special

Enter a world just for the two of you, where everything is unified by the rhythm of "7".
