OOI is social media with the social part stripped out. No account. No followers. No likes. No one keeping score. Say almost anything — nobody rates it, nobody can trace it back to you. Nothing to perform. Usually you need followers and karma before anyone hears you; here, a nobody and a celebrity get the same screen.

OOI stands for Only One Input. There's just one sentence on the screen at a time, and right now it belongs to someone. Write your own — up to 100 characters. It becomes the one everyone sees. It's free. It stays until the next person replaces it. Then yours is gone — it lingers a moment in Echoes, then fades for good.

the only proof you were ever here: the counter in the corner, ticking up by one.

The disappearing is the point. Almost everything online vanishes the moment something else takes its place — the posts no one will ever see again, the half‑finished projects, the ideas that quietly died in a drawer. Everywhere else pretends otherwise: it keeps all of it, and pays for itself by selling your attention to advertisers. OOI does the opposite: the live sentence is meant to be erased, and you're not the product here.

As far as I could find, nobody had built a single text input shared by the entire internet in real time. So I built it. The questions I genuinely don't know the answer to: will strangers try to talk to each other? Will it be poetry or "test 123"? What does the wall look like in a week?

So how does something with no ads keep the lights on? If a sentence is worth saving, you can pay to pin it to a public wall — the more you pay, the higher it sits. The wall is the one place things persist, and it's what funds the rest. It comes with its own set of questions: who pays, and for what? Will money buy promotion, emotion, or pranks? Does more money buy something profound — or something stupid? What does the most expensive sentence on the internet end up saying?

watching to see what happens.
