Gemholic

A private on-device AI companion with personality — voice, photos and a thinking mode. Fully offline.

App StoreComing soonJoin TestFlight

Gemholic is a personal AI companion that runs entirely on your iPhone. Chat by text or HiFi voice, share up to nine photos at once, and switch on a deeper thinking mode for harder questions — all processed on-device, fully offline, with nothing ever sent to a server. With memory of your chats and the occasional check-in, it feels less like a tool and more like a companion.

Highlights

Truly Private

Everything runs on your device. No accounts, no analytics, no cloud — your conversations never leave your iPhone.

Voice & Vision

Talk with HiFi voice and share up to 9 photos at once, so the AI understands the moment, not just the words.

Thinking Mode

Ask it to think and it switches to a deeper, step-by-step reasoning mode for tougher questions.

A Real Companion

A warm, characterful persona that remembers your chats and even reaches out on its own between sessions.

Offline & Fast

After a one-time setup download it works with no internet — quick, on-device responses anywhere.

Native & Fluid

Hand-tuned SwiftUI throughout — springy message bubbles, a breathing typing indicator, and first words typically under a second on recent iPhones.
