Sleeveworks is private AI with a point of view. Choose a personality, type or talk, and keep the conversation close. Its language model runs directly on your iPhone instead of sending every thought to a cloud AI service. MEET THE CAST Start with Companion, Gremlin, Pengo, Shekky, and Sage. Browse every character, read sample replies, and hear their on-device voice before choosing. Expand your cast with one-time personality unlocks, including Atlas the accountability coach, Bea the warm Southern grandmother, Quill the theatrical bard, Specter the gothic storyteller, and more. Each personality brings a distinct voice, attitude, and way of seeing the conversation. VOICE THAT FEELS LIKE CONVERSATION Tap Talk, speak naturally, and hear Sleeveworks answer. After a reply, the microphone can reopen automatically so the conversation keeps moving. When parallel capture is available, Sleeveworks can continue listening while it responds and place longer interjections in Up Next instead of derailing the current answer. Interrupt at any time when you want to take the floor. PRIVATE BY DESIGN After the one-time model download, core conversations are processed on your iPhone and can work without an internet connection. No account. No advertising. No tracking or analytics. No API key. Optional Wikipedia lookup is off by default and only connects when you enable it. MADE FOR REAL CONVERSATIONS - Keep local conversation history and context - Choose an on-device model suited to your iPhone - Switch personalities without changing apps - Preview character voices before choosing - Type while a response is still being generated - Stop a response without clearing the conversation - Choose between Paperwhite and system themes - Continue chatting after the model is downloaded, even offline Sleeveworks puts the model, the conversation, and the cast directly on your iPhone. Some personalities require a one-time in-app purchase. Initial setup requires an internet connection and sufficient storage to download an on-device language model. Model availability and performance vary by device.
