Sleeveworks just shipped.
It's a private AI companion that never leaves your phone.
It runs entirely on-device. No account, no cloud, no data collection, and after a one-time model download, it works completely offline. Your conversations stay on your iPhone, period.
What makes it fun isn't just the privacy.
It's the cast:
🐧 Pengo — a goofy, big-hearted genius penguin
🎤 Shekky — a fast-talking nightclub comic
🌿 Sage — a calm, reflective mentor
😈 Gremlin — a witty little troublemaker
☕ Companion — a warm, easygoing friend
Each one has its own voice, literally.
You can chat by text or just talk out loud, with natural neural speech generated on the device itself.
Under the hood: open-source large language models running locally via Apple's MLX framework, on-device neural text-to-speech, and a reading experience inspired by e-ink warm paper, serif type, no bubbles.
Building this taught me a lot about squeezing billion-parameter models into a phone's memory budget, and about how much of an "AI product" is really character design.
It's free on the App Store. Link in the comments, and I'd love to hear which personality you end up talking to most.
My favorite is Pengo.
