FAQ
Is Elephas free to use?

Elephas indexes your files locally on your Mac and automatically redacts 28 types of sensitive data (names, SSNs, account numbers, case numbers, and more) before any content reaches a cloud AI model.

Where it holds up
- Indexes documents locally on your Mac and redacts 28 types of sensitive data (names, SSNs, account numbers, case numbers, and more) before anything reaches a cloud model
- Fully offline mode runs AI entirely on-device when nothing should leave the room
- Super Command adds AI writing, rewriting, and translation into any Mac app via one keyboard shortcut
- Super Brain gives grounded, cited answers from your own documents instead of generic chatbot responses
- You can bring your own API key from 15+ providers (OpenAI, Claude, Gemini, Groq, DeepSeek) for unlimited usage
- Every download includes 7 days of Pro automatically, no credit card required
Where it falls short
- Mac and iOS only today — Windows support is still on a waitlist
- Super Command and other text-writing features are unavailable in the Mac App Store version due to sandbox restrictions; the full version requires downloading directly from elephas.app
- Higher-value features (Super Brain, redaction visibility, offline workflows) require at least the Professional or Pro+ plan
