Run powerful AI models completely offline. No cloud, no subscriptions, and zero data leaving your phone.

AI Playground brings state-of-the-art language models directly to your Android device. Everything — your conversations, prompts, and history — stays 100% private and on-device.

🛡️ PRIVACY BY DESIGN
• 100% On-Device: Inference, chat history, and prompts stay on your phone.
• Airplane Mode Ready: Turn off Wi-Fi or cellular — AI Playground runs seamlessly offline.
• Zero Data Collection: No telemetry or external server traffic unless you opt in.

🚀 TWO HIGH-PERFORMANCE ENGINES
• llama.cpp: Run GGUF models (Qwen, Llama, Gemma, Phi, Mistral) directly on ARM64 CPU.
• MediaPipe LLM Inference: Google's optimized runtime for mobile .task bundles.

📥 DISCOVER & DOWNLOAD
• Curated Model Catalog: One-tap downloads for Qwen3, Qwen2.5, Gemma 3, Gemma 2, Llama 3.2, and Phi-3.5.
• Hugging Face Hub Search: Explore and download thousands of community GGUF models inside the app.
• Safe & Verified: SHA-256 checksum validation with background resume support.

📂 BRING YOUR OWN MODELS
• Single & Batch Import: Easily import any .gguf or .task files from internal storage, SD card, or USB OTG.
• Smart Duplicate Detection: Fingerprints files to prevent duplicate imports.

💬 CHAT & QUICK PROMPTS
• Quick Prompt Chips: One-tap shortcuts for email drafting, code writing, proofreading, summarization, and brainstorming.
• Rich Markdown & Math: Beautiful rendering for code blocks, lists, and formatted text.
• Thinking Mode: Toggle deep reasoning traces for supported models (e.g. Qwen3).
• Generation Metrics: Live tokens/sec speed, latency, and total token count.

🎙️ VOICE & ACCESSIBILITY
• Hands-Free Dictation: Continuous speech-to-text with auto-restart listening.
• Natural Text-to-Speech: Read responses aloud with auto-detection for Arabic script.

🛠️ ADVANCED FINE-TUNING & MEMORY
• Full Parameter Control: Adjust Temperature, Top-P, Top-K, Max Tokens, Context Length, and Seed.
• KV Cache Quantization: Saves up to 75% RAM for longer conversations without crashes.
• GPU Driver Crash Shield: Isolated Vulkan driver probing with automatic CPU fallback.
• Smart RAM Guard: Pre-checks device RAM to prevent low-memory crashes.

🎨 MODERN DESIGN & LOCALIZATION
• Android 15 Edge-to-Edge: Sleek layout with transparent status and navigation bars.
• 9 Languages Supported: English, Spanish, German, French, Hindi, Arabic (RTL), Japanese, Portuguese, Chinese.
