Dating where the AI swipes, messages and chooses on your behalf
Ditto is an AI agent you reach on iMessage and SMS. To start, create an account. It reaches out on a schedule.
How Ditto works
Ditto is a college matchmaker that runs on a weekly clock: submit your preferences by Tuesday night, get one match in iMessage at seven on Wednesday, and it curates the date. Dates happen at chosen spots on the campus you are near, and it says it only matches verified students who are 18 or over.
It is the largest campus number in this directory by a wide margin. The front page claims 184,110 students and more than a hundred schools, against the 42,000 across five campuses recorded here before, and the FAQ adds that 70% of users now get a first date within two days.
The policy names Anthropic, OpenAI and Google as its AI service providers, which puts it among the minority here that name any, and it states the thing a matchmaker has to state: when you decide to proceed with a match, your contact details go to the other person. Everyone in that exchange is a Ditto user, which is why the question about people who never signed up does not arise here.
Two operational details are worth having. The operating company is Popcorn AI Tech Inc., which appears only in the policy. And Ditto does not have a number: its FAQ explains that the lines get busy and offers to move you to a new Ditto number without resetting your profile, which is an unusually plain description of what running a consumer product on iMessage actually involves.
Who carries its messages has two answers on the record. Photon's engineering blog names Ditto as a customer, which is the row above; on 18 September 2026 Linq's account said it powers Ditto too. A product can use two carriers, and neither company's page says which, so the row keeps the earlier source and this sentence keeps the other.
