Cortis: Private AI Chat

Cortis: Private AI Chat is a privacy-centered conversational assistant designed for secure, local-first interaction. Cortis: Private AI Chat organizes your conversations, notes and file references while giving you choices about cloud sync and processing. Cortis: Private AI Chat supports customizable prompts, selectable models, and offline use so you can control where your data is processed.

Key features

• Local-first processing — Run models on your device to keep conversations private when possible.
• Optional encrypted sync — Back up and sync data only if you enable secure, encrypted syncing.
• Chat and notes — Keep searchable chat history, save important replies, and organize content with folders or tags.
• File and media support — Attach or reference documents and images within conversations for context-aware responses.
• Custom prompts and tools — Create templates, adjust system instructions, and choose model settings for different tasks.

Privacy and security

By default data stays on your device; any cloud features are optional and require your consent. The app requests only necessary permissions and provides controls to export or delete your data. Review privacy settings to manage sync, backups and local storage behavior.
