Sage: On-Device AI Assistant

Sage is an AI assistant that runs entirely on your iPhone. Chat, translate, cut out, redact, transcribe meetings, OCR handwriting—all on-device. No servers. No tracking.

Sage is an AI assistant that runs entirely on your iPhone. All processing — chat generation, image understanding, speech recognition, text recognition — happens locally on your device. Nothing is ever sent to any server.

WHY SAGE IS DIFFERENT • Fully offline: works in airplane mode • Zero tracking: no third-party analytics, advertising, or tracking SDKs • No subscriptions: one-time in-app purchase unlocks every pro feature • Fully transparent: models are downloaded from public sources like Hugging Face
