AI Buddy - Offline AI Chat

About AI Buddy - Offline AI Chat

AI Buddy is a private AI chat and voice assistant that runs entirely on your Android device. Download a small language model once and use it forever — no accounts, no subscriptions, no cloud, no tracking, no ads.

Ask questions, brainstorm ideas, draft messages, explain code, plan a trip, or just chat. Every reply is generated on your phone by a real large language model. Your conversations never leave the device.

**What makes AI Buddy different**
• 100% on-device inference — powered by Google's Gemma models via MediaPipe LLM Inference
• Works fully offline once installed — perfect for airplane mode, travel, low-signal areas
• Private by design — no analytics, no cloud, no external servers
• Free forever — no subscriptions, no in-app purchases, no ads
• Zero account setup — open the app and go

**Chat**
• Streaming replies token by token, exactly like the assistants you know
• Markdown rendering — bold, lists, code blocks with syntax-friendly monospace
• Copy any answer with one tap
• Suggestion cards on the empty state to help you start

**Voice mode**
• Tap the microphone for a hands-free conversation
• On-device speech recognition (no audio uploaded)
• Natural text-to-speech reads answers back to you
• Auto-continues the conversation after each reply — talk naturally

**Conversations**
• Automatic history with smart titles
• Full-screen sidebar with instant search across every message
• Pin important chats to the top

**Choose your model**
• Gemma 3 · 1B (recommended) — best speed and quality balance, ~530 MB
• Gemma 2 · 2B — higher quality answers for flagship phones, ~2.5 GB
• Swap models any time from Settings

**Privacy that actually means something**
AI Buddy does not:
- Send your messages to any server
- Track what you type or say
- Require an account or email
- Show ads or collect analytics
- Need any permissions beyond microphone (for voice mode) and network (for the one-time model download)

Your chats live in the app's private storage. Uninstall and every trace is gone.

**Requirements**
• Android 7.0 (API 24) or newer
• arm64 device (any modern phone)
• Roughly 1–2 GB free storage for the model
• Wi-Fi for the one-time download

**Use it for**
• Studying and research
• Writing emails, replies, and messages
• Brainstorming and planning
• Explaining tricky topics in plain language
• Learning a new subject
• Coding help and quick regex or shell tips
• Practising a language
• Any question you'd normally ask a cloud chatbot — but keep it private

**Under the hood**
AI Buddy uses Google's Gemma family of open-weight models with MediaPipe's LLM Inference runtime. Inference runs on your device's CPU or GPU depending on what performs best. No data ever leaves your phone.
