Cortis: Private AI Chat

Cortis: Private AI Chat provides a private, offline-capable chat interface that lets you interact with AI assistants while keeping data on your device. The app emphasizes local control, configurable model settings and straightforward history management to support personal workflows.

How it works

Cortis: Private AI Chat runs models locally when available and can connect to external models you configure. Chat history is stored on-device by default, and you decide when to export, back up or delete conversations. Data is not shared with third parties unless you explicitly choose to send it.

Key features

With Cortis: Private AI Chat you can use on-device models or connect to servers you manage, customize assistant behavior including response length, tone and system prompts, manage your chat history and exports, and attach local documents to give context to conversations without automatic uploads to outside services.
