Language Tutor · Baro vs Sacred Knowledge Vault

ON-DEVICE TUTOR NEEDS APPLE INTELLIGENCE. On an Apple Intelligence iPhone (15 Pro+, iOS 26) with Apple Intelligence on, conversation stays on your phone. On a phone that cannot run that model, enjoy 5 free AI conversation turns daily or activate Cloud Tutor. Written exercises and guides work on every iPhone. Practice a new language by talking — privately, on your own phone. Language Tutor is a language-learning tool you practice by chatting. A patient tutor role-plays a conversation partner in the language you're learning, replies at your level, and gently corrects your mistakes so each exchange becomes a small lesson. No teacher to book, no class to attend, no judgment. ON-DEVICE FIRST, PRIVATE BY DESIGN On an Apple Intelligence phone the tutor is Apple's own on-device model — nothing to download, no account. Turn on airplane mode and keep practicing to see for yourself. Saved phrases and settings always stay on your phone. LEARN BY DOING, NOT MEMORIZING • Voice input — tap the mic and practice speaking aloud; on-device speech recognition transcribes words privately. • Pronunciation speed & auto-speak — listen at a comfortable, slower pace designed for beginner learners, or have replies read automatically. • Spoken guided dialogue — tap any line in guided conversations to hear clear native pronunciation on any iPhone. • Conversation practice — chat through real scenarios: ordering food, the airport, small talk, directions, and more. • Gentle corrections — mistakes are corrected kindly, with a hint when you get stuck, so you actually improve. • Suggestions when stuck — tap starting lines, or ask “What should I say?” mid-chat for short reply ideas. • Instant meaning — tap a tutor message and what it means appears in your own language, right under the bubble. • Choose your level — beginner to advanced; the tutor adjusts how it speaks to you. • Pick your target language — separate from the app's menu language. • One tap to start — your language, level and scenario carry over from last time, so practice begins the moment you open the app. LEARN KOREAN — INCLUDING TOPIK Practice Hangul conversation by exam band (TOPIK 1–6). The tutor coaches particles and honorifics, and written drills follow the same bands. Travel Korean is here too — speaking practice, not flashcards. A REAL STUDY TOOLKIT • Phrasebook — save useful lines from any chat into a local phrasebook, grouped by scenario. • Scenario guides — offline guides for common situations, plus grammar and usage tips. • Review — come back to your saved phrases and practice them again. • Practice record — days practiced, conversations and saved phrases at a glance, with a shortcut to whatever is due for review. This record lives only on this phone. BUILT THE BARO WAY • Works offline — the on-device tutor practices anywhere, even with no signal. • No ads, no tracking, no analytics, ever. • Big text, high-contrast design, single-tap controls — easy at any age. • English, Korean, Japanese, German, French, Arabic, and Simplified Chinese interface. OPTIONAL CLOUD TUTOR — AUTO-RENEWING SUBSCRIPTION Only for phones that can never run Apple Intelligence, and only after a single notice. Apple Intelligence phones stay on-device and do not need it. Written exercises stay available on every iPhone without it. No ads. Cloud Tutor — US$0.99 per month. Renews automatically until you cancel; manage or cancel in Apple Account settings.

Where the on-device tutor cannot run, the app says so — there is no silent stand-in. Part of the Baro family — The tools you reach for first.

An AI knowledge tool with an exclusive role-playing system featuring two separate knowledge base modes. All conversation data is stored locally to fully protect your privacy.  Six Exclusive Roles： You must pick an identity on your first launch: Angel, Demon, Sage, Knight, Fox and Hermit. Each role comes with unique salutations, conversation tones and placeholder texts for the input box. You may switch roles anytime in Settings. The AI opens every reply with role-specific greetings for an immersive Q&A experience.  Dual Knowledge Base Modes — Balance of Convenience & Privacy： 1. Sacred Library — Official Built-in Public Knowledge Base It includes ten complete categories: full-stack development, general learning, quotes & proverbs, design thinking, workplace communication, history & literature, finance & psychology, space science and more. Pre-built prompt templates named Wisdom Sparks are available. You can read daily offline quotes without API configuration — ready to use right after installation.  2. Personal Codex — Custom Private Model Knowledge Base (Max Privacy Protection) Create your private knowledge vault by entering your LLM API address, secret key and model name. All conversations are only sent to the third-party interface you configure. The app will not collect, upload or retain your Q&A content on its own. Full chat history is saved locally in the on-device FMDB database with no cloud uploads. You retain full ownership of all your data.  Full Suite of Knowledge Management Tools： - Sacred Archives: Conversations are auto-saved locally, paginated and grouped by knowledge base; only accessible on your device. - Sacred Favorites: Long-press any dialogue to save it locally for later review. - Wisdom Sparks: Built-in prompt templates to start knowledge inquiries with one tap.  Privacy & Security Guarantees： 1. Local Data Storage: All chats, favorites and history remain in your local database with no automatic cloud uploads. 2. Isolated Private Mode: Messages in your private vault are only relayed to your self-provided model endpoint. We never access your API keys or conversation data. 3. Encrypted API Key Storage: Your custom model keys are securely stored in Keychain with no plaintext caching. 4. Full Data Control: Clear all local chat cache and device data in one tap via Settings.  Target Users： Programmers, designers, educators, copywriters, students, casual knowledge seekers, and users who run private LLMs and prioritize data privacy. We keep updating built-in knowledge bases and role interaction experiences continuously.
