Loci - Private, Offline AI

Loci by Cozu is a private Android AI assistant that runs advanced language models entirely on your device — no account and no cloud AI server. Your conversations never leave your phone. Everything you type or dictate is processed on-device and stored only in a local database, so your chats, notes, and the things Loci remembers about you stay yours. Loci has no accounts and doesn't know who you are. WHAT YOU CAN DO • Chat with capable AI models that run 100% locally on your phone • Work completely offline — once a model is downloaded, no internet connection is needed • Talk hands-free with voice conversation mode and on-device dictation • Pull in fresh information with optional web search (only your search query is sent, never your conversation) • Choose the model that best fits your device, powered by open models from Hugging Face • Enjoy a calm, fast, distraction-free dark interface PRIVATE BY DESIGN Loci is built on a simple idea: your AI should work for you, not harvest your data. • Your conversations are never uploaded and are excluded from Android cloud backup • No ads, ever — and your data is never sold • Crash and performance diagnostics are on by default, can be turned off anytime in Settings, and never include your prompts, responses, files, or audio • On supported Android versions, Google Analytics measures new installs and first successful answers to help us understand Google Ads performance. It uses an app-instance identifier and basic app, device, network, and referral information, never your prompts or answers. This measurement starts after onboarding with diagnostics enabled and can be turned off in Settings. Whether you're offline, traveling, or you just value your privacy, Loci gives you a genuinely private AI assistant that lives on your Android device.
