Written by the checker for a first version. Paste it into Vibecode as is, or change it to make the app yours.
Build an iPhone app for people who want to chat with fictional AI characters and create their own personas. The main screen should show a library of original characters with names, short descriptions, and simple avatars. Tapping a character opens a chat with message bubbles, a text box, and a send button. Save conversations on the device so I can reopen them. Add a create button that opens a form for a character's name, personality, backstory, and opening greeting. Use a dark purple theme with clear text and rounded cards. Include realistic sample characters and simulated replies for the first build. Label chats clearly as AI conversations, not real people.

Vibecode builds a first version from one prompt, and the checker would start with these parts: browse a small library of original characters; chat with a selected character and save the conversation on your device; create a custom character with a name, personality, and greeting. Plan on an afternoon for a working first version with its real features.
Vibecode's first build is free for new accounts that sign up with Google or Apple on the web or the iPhone app, as the account's first project: one build of about 10 minutes with up to 3 features, on sample data. After that you need credits, from a paid plan or auto-reload. For your own version of Character.AI, the checker lists these costs: Vibecode Plus ($20 a month); Apple Developer Program ($99 a year).
