SpeakLocal — Offline AI Tutor

The only AI language tutor that never uploads your voice. SpeakLocal runs entirely on your phone — no cloud, no subscription required, no data collection. Your conversations stay yours. Forever. Practise speaking English, Mandarin Chinese, or Japanese with an AI tutor that listens, responds, and corrects you in real time. SpeakLocal uses Google's Gemma AI model running directly on your phone to hold natural conversations across 25 real-world scenarios — coffee shops, job interviews, airport check-in, doctor visits, business meetings, first dates, and more. Every turn comes with a pronunciation score and one specific tip for what to fix next. A built-in spaced-repetition vocabulary vault remembers the words you struggled with and brings them back at the right moment for long-term retention. Works on the plane. In the subway. In the mountains. Anywhere. After the first one-time model download (about 3 GB), SpeakLocal requires zero internet connection — no Wi-Fi, no SIM card, no cellular data. Perfect for travellers, language learners on a budget, and anyone tired of apps that throttle their practice when they're offline. Unlike ELSA, Speak, and TalkPal — which all upload your voice recordings to their servers for processing — SpeakLocal processes everything locally. Your microphone audio never leaves the device. Open Settings → Privacy Center to see, byte for byte, exactly what's stored on your phone and what's been sent anywhere else (spoiler: 0 bytes). When you delete the app, every conversation, every vocabulary card, every practice session goes with it. No retention, no server-side copy, no "we may use your data to improve our models" small print. Free includes: • 3 speaking sessions per day, 10 minutes each • 5 everyday scenarios (coffee shop, casual chat, shopping, directions, self-intro) • Pronunciation trainer (10 drills per day) • Vocabulary vault for up to 50 saved words • Daily streak tracking and progress charts • Full Privacy Center with on-device data inspector Upgrade to Pro for: • Unlimited speaking sessions • All 25 scenarios + Business English, JLPT N3, HSK 4, and British-accent packs • Larger AI model (Gemma 3n E4B) for richer cultural and idiomatic replies • Unlimited vocabulary vault • Zero ads — the Home screen ad strip you see on the free plan disappears The same privacy guarantee applies to both free and Pro: your voice stays on your phone, always. The only difference is what the AI can do once it's listening. Built for serious language learners by language learners. SpeakLocal is a one-person project that earns from a small in-app subscription so it can stay independent — no VC funding, no growth-hacking dark patterns, no email harvesting. If you've ever wanted to practise speaking out loud without worrying about who's recording you, this is the app.
