Castmates is a private, on-device AI app for interactive character stories, running entirely on your iPhone. Most AI apps send every word you type to the cloud and make you sign in. Castmates doesn't — the model lives on your device, so your conversations are never sent to a server, there's no account, and it even works offline. Meet a cast of 32 characters who actually stay in role. They don't reply like a chatbot — they narrate the scene, act, and remember what happened last time, so the story keeps building each time you come back. A CAST FOR EVERY MOOD Meet 32 hand-crafted characters across 8 genres: • Companions — a loyal best friend, a warm life coach, a hype-man trainer • Romance — slow-burn crushes and devoted partners • Fantasy — elven rangers, dark knights, fae sorceresses, gentle orcs • Sci-Fi — sardonic ship AIs, starship captains, curious aliens • Anime — tsundere rivals, shy schoolmates, bubbly childhood friends • Historical — Regency nobles, samurai, Renaissance inventors, jazz-age icons • Mystery & Horror — noir detectives, vampire countesses, eerie keepers • Adventure — pirates, treasure hunters, wasteland survivors DROP INTO A SCENE Every character comes with ready-made scenarios — 96 in all — so you can jump straight into a story, or set your own opening scene and tone. BUILD YOUR OWN Create custom characters end to end: name, persona, greeting, appearance, tone, and a signature opening scene. Set their avatar from your photo library. They'll act exactly the way you wrote them. PRIVATE BY DESIGN — ON-DEVICE AI The whole AI runs locally on your iPhone. After a one-time model download: • Your conversations are generated and stored on-device — never sent to a server • No account, no sign-up, no profile • Nothing is logged on our servers or used to train models • It keeps working in airplane mode — on a flight, on the subway, off the grid THEY REMEMBER YOU Castmates summarizes past sessions, so characters recall who you are and pick up the thread days or weeks later. FREE TO START Start free with the full cast. Upgrade to Castmates Pro for unlimited messages and unlimited custom characters — and like everything else, kept private on your device. Castmates Pro options: • Monthly — $9.99 • Annual — $39.99 (best value) • Lifetime — $59.99 (one-time purchase, not a subscription) Payment is charged to your Apple ID at confirmation of purchase. Subscriptions automatically renew unless auto-renew is turned off at least 24 hours before the end of the current period; the Lifetime option is a one-time purchase that does not renew. Manage or cancel anytime in your App Store account settings. Privacy Policy: https://get-castmates.com/privacy Terms of Use (EULA): https://get-castmates.com/terms

Whether you love fantasy, sci-fi, romance, or mystery, there’s a ready-made scene (or 96!) to jump into.For anyone who values privacy, creativity, and seamless storytelling, Castmates is a must-have. 10/10!

• Less waiting to start: your castmate's AI now downloads in the background right after install • Swipe any reply to see other takes on the same moment • Scene direction: add a one-off note to steer how the next reply opens • Characters can text you first when a story has gone quiet • Tapping a notification opens that conversation directly, even from a cold start • Setup and stability fixes throughout
