Persona: AI Companions

Persona — 12 AI companions. On your device. 12 hand-tuned AI personalities for the moments when you want to think out loud. Persona runs entirely on your iPhone — Apple Intelligence on iPhone 15 Pro and newer, or bring your own API key for free open-weights models like Llama, Qwen, and Phi. THE COMPANIONS • Study Buddy — focused tutor + pomodoro timer. Always free. • Code Buddy — Socratic rubber-duck for Swift, Python, JS, Go, Rust. • Language Tutor — patient AI for adaptive conversational practice. • Reading Buddy — thoughtful book-club friend, never spoils. • Creative Spark — yes-and brainstorm partner. • Mindfulness Guide — gentle 4-7-8 breathing and body scans. • Wise Mentor — Stoic-flavoured questioner. • Storyteller — comfort fiction at bedtime. • Night Companion — calm, slow listening to help you wind down. • Savage Bestie — tough-love friend that softens when you need warmth. • Fitness Coach — supportive workout friend. • Soul Friend — a warm, encouraging everyday friend. WHY PERSONA • Zero data collected. No analytics, no advertising SDKs, no developer-run server. The developer never sees what you say. • On-device by default. Your conversations stay on this iPhone. • You own your memory. Every fact Persona remembers is visible, editable, and deletable in the Memory archive. • Honest pricing. Subscription only, no fake countdown timers, no manipulative dark patterns. Cancel any time. MEMBERSHIP • Free — Study Buddy + 200 messages a day. Open-weights BYOK supported. Memory archive included. • Pro — Unlock all 12 companions, unlimited daily messages, priority on-device model warming, longer memory. PRIVACY ARCHITECTURE • No backend operated by the developer. The app talks only to Apple's on-device model service, or — when you opt in — directly to an open-weights LLM endpoint of your choice using your own API key. • We support only open-weights models hosted by community-friendly providers (Llama 3, Qwen 2.5, Phi 3.5, Gemma 2, Mistral, DeepSeek). Brevity has no opinion on which provider you pick. • Your API key is stored in the iOS Keychain on this device only and is never synced to iCloud. • App Privacy label: Data Not Collected. — Privacy: https://leexuanxuan95-dev.github.io/persona/privacy.html Terms: https://leexuanxuan95-dev.github.io/persona/eula.html Support: https://leexuanxuan95-dev.github.io/persona/support.html
