FAQ
Astra AI Assistant questions
Does Astra work without the internet?
Yes. Astra runs on local language models through Ollama or on Apple Intelligence, so chats, memory and document search work on your Mac. Only optional cloud features, like image generation, need a connection.
Does my data leave my Mac?
No. Chats, memories, tasks and documents are stored in a private database on your Mac. Cloud features are off until you enable them yourself.
Can Astra answer questions about my own documents?
Yes. Point it at your notes, PDFs or Obsidian vault and ask in plain language — it searches by meaning, not just keywords.
How is Astra different from ChatGPT on Mac?
ChatGPT runs in a cloud data center. Astra lives on your Mac: it uses local models, remembers you over time, works with your calendar, reminders and files, and can control your Mac.
Does Astra support voice?
Yes — push-to-talk, hold-to-talk, continuous listening and a wake phrase, with replies spoken by a macOS voice, a local Qwen3 voice or a cloned voice of your choice.
