PerChat AI, the chatbot app powered by your own devices. Unlike other AI chatbot apps, all Characters, Chats, and data remains on your iPhone at all times and no data is shared. This app can run AI chats all on your iPhone if you wish, no internet required! It supports a wide range of iPhones, starting from the iPhone XS and up. 4GB of RAM is recommended but the more RAM you have, the better! If you happen to have a Mac or Windows PC lying around, you can have more complex and interesting chats by using that machine as a remote server for this app. Note that remote chatting is only supported on your own home network, or with the use of a VPN to access outside your home. You can run the PerChat AI server on your Mac or Windows PC with some hand-picked models, or you can run your own server such as LM Studio or Ollama, and have character chats using those tools. Features: - create richly detailed Characters to chat with, and Personas to chat with - partake in epic conversations with dungeon masters, real celebrities, or any character you can imagine - choose from a curated list of LLM models that will run well on your iPhone to change the flavor of your chats - run a vast number of LLMs on your own Mac or Windows PC to offload computing, and improve chat quality
