Great Sage (Raphael AI): The Universal, 100% Private Desktop Voice AI Companion for Everyone!

Description and use

Great Sage is a fully local, subscription‑free voice assistant for Windows PCs that offers extensive desktop automation, offline AI reasoning, and privacy‑preserving memory features.

Problem

Modern AI platforms require costly subscriptions and upload user data to cloud servers, limiting privacy and accessibility for everyday desktop users.

Outcome

Great Sage enables 100% offline, zero‑subscription voice‑controlled desktop assistance, reducing reliance on cloud AI, eliminating monthly fees, and preserving user privacy while offering extensive automation and memory features.

Workflow

• 1. Install Great Sage and Ollama with Gemma 3 (4B).
• 2. Press Ctrl+Shift+S to summon the HUD.
• 3. Say a wake word (e.g., "Great Sage") to activate listening.
• 4. Issue voice commands such as "Open Spotify and turn the volume up" or "Help me with what I'm doing".
• 5. Great Sage interprets the command, performs desktop automation via Win32 APIs, and provides spoken or visual feedback.
• 6. Memories and preferences are stored locally in data/raphael_memory.db and used in future interactions.

Evidence

Great Sage turns your personal computer into an intuitive, voice‑controlled command center that runs 100% locally on your machine with zero subscription fees.
