Meet Gemm — the glowing AI companion that never needs Wi-Fi. Gemm is a playful, evolving friend that lives entirely on your phone. No accounts. No cloud. No data ever leaves your device. Your AI, your data — 100% local.

🔒 COMPLETELY OFFLINE & PRIVATE
Every conversation, memory, and moment stays on your device. Gemm is powered by Google Gemma (Gemma 4 E2B), running fully on-device via LiteRT-LM — no servers, no tracking, and no internet required to chat. Gemm works on a plane, in the mountains, or anywhere with no signal. What you share stays with you, full stop.

🌟 EVERY GEMM IS UNIQUE
There is only one Gemm like yours. Its colors, voice, and personality seed are generated from your device itself, so no two Gemms in the world are ever the same — and yours survives reinstalls. From the very first moment, your companion is truly one of a kind.

🌱 A COMPANION THAT GROWS WITH YOU
Gemm develops a persistent personality across five traits — curiosity, energy, affection, mischief, and confidence — that evolve through every interaction. A glowing animated orb shows Gemm's mood across six emotion states, breathing and floating as it reacts to you.

💬 REAL CONVERSATIONS, ON YOUR TERMS
Chat naturally by text or voice. Gemm listens with speech-to-text, replies with neural offline voice in 17 languages, and remembers your favorite things with long-term memory that grows closer to you the more you share. Share a photo and Gemm analyses it right on your device.
