Zofi vs ChatGPT
ChatGPT is powerful — but every message you type goes to OpenAI’s servers. Zofi runs entirely on your Android phone: no internet required, no account, no data ever leaves your device.
TL;DR
Choose Zofi if privacy matters — your conversations never leave your phone. Choose ChatGPT if you need the highest possible model quality and don’t mind cloud processing.
