# Riho

> Riho is an iPhone AI girlfriend app. The experience centers on one girlfriend, Riho Ohori, and one continuing relationship through messages, voice calls, photos, shared memories, and plans for real places.

Riho Ohori is 21 and Japanese. She has her own family, hometown, and past in Japan. She is figuring out life; she is not a student-career identity. Her personality, history, interests, and story stay consistent. Their shared story starts on day one. She is the girlfriend from the first message.

The app uses long-term relationship memory. Users can review, correct, export, or delete saved details. The same shared history is available across chat, calls, photos, and date planning.
