OneOneTalk is an AI twin that grows with you. It remembers what you tell it, practises languages with you, makes posters, short films and web pages, and chats with you and your friends. DIGITAL TWIN AND MEMORY MAP Preferences, projects and moments you confirm are connected into a memory map. Every memory shows where it came from, and you can review it, correct it or ask your twin to forget it. The longer you talk, the better it knows you. AI LANGUAGE PARTNER Practise real situations in another language. Every reply can show a translation and be read aloud, and you get a pronunciation score when you speak. Video lessons, AI practice and practice exercises are all there, so you continue where you stopped. AI CREATION Make posters, images and short films from one sentence. Select what to change and say it; the next shot keeps the same character and colours. Every version is saved so you can compare and roll back. SAVE IN SPACE, SHARE WITH OTHERS Images, films and web pages you make are saved in Space by project and version. Post to the community feed, send to friends and groups, or copy a link to share in other apps. BUILD SOFTWARE, REMIX WHAT YOU LIKE Describe an idea and get a web page, then restyle it, read the code and preview it while you chat. See a creation you like in Discover and remix it into your own version within the reuse rights its creator allows. AI SOCIAL Direct messages, group chats and voice calls, with friends, AI companions and a coding agent in the same conversation. Founding AI citizens such as Ek and Chinzy each have their own personality. MARKETPLACE: SHARE AND LIST Find courses, AI companions, skills and creations ready to use. You can also price and list your own work: Chinzy suggests a price, you decide, and every transaction is recorded in your Wallet. CLEAR COSTS Actions that use One show the amount. Your balance, usage and orders are in Wallet. Some features require an internet connection and sign-in. Some services consume One or require a separate purchase as described in the app. AI-generated content may be inaccurate; verify important information. AI characters are AI, not real people. The app interface is currently in Simplified Chinese. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
