Key Principles
Section titled “Key Principles”Privacy First
Section titled “Privacy First”All your data — conversations, tasks, settings — stays on your machine. There is no cloud sync, no telemetry, and no external data collection. You own your data completely.
Choose Your AI Provider
Section titled “Choose Your AI Provider”Stina does not bundle any AI models. Instead, you connect to the AI provider of your choice:
- Ollama — Run models locally for fully offline AI (Llama, Mistral, Gemma, etc.)
- OpenAI — Use GPT-4, GPT-4o, o1, and other cloud models
- Build your own — Create a custom provider extension for any API
Work Anywhere
Section titled “Work Anywhere”Stina is available as:
- Desktop app (Electron) — Full-featured native experience for macOS, Windows, and Linux
- Web app — Self-hosted web interface accessible from any browser
- CLI / TUI — Terminal interface for keyboard-driven workflows
Extensible
Section titled “Extensible”Stina’s functionality comes from extensions. The core app provides the chat interface and scheduling engine, while extensions add capabilities:
- Mail Reader — Connect to IMAP, iCloud, Gmail, or Outlook
- Work Manager — Todos, projects, and reminders
- People Registry — Remembers people mentioned in conversations
- And more — or build your own
