Sleeveworks

Chat with a cast of AI characters — a noir detective, a Shakespearean bard, a cosmic optimist and more. Private, on-device, and fully offline on your iPhone.

Sleeveworks is a private AI companion that runs entirely on your iPhone. No account, no cloud, no sign-up — after a one-time model download, it works completely offline, and your conversations never leave your device. Chat by text or talk out loud with a cast of characters who each have their own voice and personality: • Companion — a warm, easygoing friend • Pengo — a goofy, big-hearted genius penguin • Gremlin — a witty, mischievous troublemaker • Sage — a calm, reflective mentor • Shekky — a fast-talking, all-ages nightclub comic UNLOCK MORE PERSONALITIES Expand your cast with premium personality packs — buy once, yours forever: • Atlas — a no-excuses strength coach • Stella — a wide-eyed cosmic optimist • Quill — a theatrical Shakespearean bard • Vance — a hardboiled film-noir detective • Doc Hertz — an eccentric mad-scientist inventor • Pixel — a hyper-energetic gamer • Bea — a warm, sassy Southern grandmother • Brio — a fiery, passionate chef • Sterling — a proper, unflappable British butler • Specter — a gothic, cozy-spooky storyteller WHY SLEEVEWORKS • Truly private — the AI runs on-device. Your chats stay on your iPhone. • Works offline — no connection needed once the model is downloaded. • Real voices — natural, on-device neural speech. Talk and listen. • Your choice of brain — switch between on-device models and free up storage anytime. • Collect characters — start with five free personalities and unlock more anytime. • Optional lookup — turn on a quick online fact-check only when you want it. No ads. No tracking. No data collection. Just a private, characterful AI that's yours. Sleeveworks runs large language models locally, so responses are limited by your device rather than a server farm — but everything you say stays with you.
