Cortis: Offline AI Assistant

Cortis enables users to chat with AI models without any network access after an initial download. Conversations remain private since processing occurs locally on the phone, with options for several models including those from Llama, Gemma, Qwen, and Phi. The app also offers multilingual support and features like streaming responses along with image understanding. Users can select from free models or upgrade via a one-time purchase for additional capabilities. Integration with Siri allows starting chats or performing tasks through voice commands even in offline environments such as airplanes or subways. Referral options provide ways to access premium features without payment. The tool emphasizes simplicity with no signup required and local storage for chat history that users control completely. It connects optionally to computer-based setups for larger models over local networks while maintaining the core focus on privacy and independence from external servers.
