Are you concerned about sharing private data, confidential documents, or personal chats with cloud-based AI? Do you need a powerful AI assistant when traveling, commuting, or working in areas without internet access?

Transform your Android device into a secure, private AI workstation with LocalAI. LocalAI is a 100% offline AI chatbot that runs open-weight Large Language Models (LLMs) entirely on-device. There is no cloud processing, no mandatory subscriptions, and absolutely zero data collection. Your prompts, documents, chats, and photos never leave your phone.

🚀 Why Choose LocalAI?

• Complete Data Ownership: Total peace of mind. Analyze confidential work, legal PDFs, and personal journals securely offline.

🧠 Run State-of-the-Art Open-Source LLMs
Discover, download, and manage GGUF models directly within our Hugging Face-powered Model Hub. Supported cutting-edge architectures include:
• Meta LLaMA 4 (Scout, Maverick) & Llama 3.x
• Google Gemma 4 & Gemma 4 Mobile
• DeepSeek-V4 (Flash & Pro distilled)
• Alibaba Qwen 3.5 & Qwen 3.6 (including MTP architectures)
• Ornith 1.0 & Bamboo 1 (high-efficiency models)
• IBM Granite 4.1 & Microsoft Phi-4

⚡ Hardware-Accelerated Local Inference
Designed for extreme speed and memory efficiency:
• Flash Attention 2: Hardware-accelerated attention for faster token generation.
• KV Cache Quantization: Q4_0/Q8_0 caching saves 30-40% RAM, preventing Out-Of-Memory crashes.
• GBNF Grammar & JSON Schema: Force structured outputs natively.
• Response Telemetry: Real-time tokens/sec, prompt/sec, and RAM/CPU hardware monitors.
• Reasoning Support: Natively surfaces `` reasoning blocks (DeepSeek-V4, Ornith).

📄 Chat with PDFs and Documents (Offline RAG)
Import PDFs, Word (.docx), Excel (.xlsx), CSVs, or text files. LocalAI parses, chunks, and embeds content locally using on-device Vector RAG (sqlite-vec). Summarize, ask questions, and chat with PDFs offline securely without an internet connection.

🖼️ Multimodal Vision AI Offline
Load any vision-capable model (like SmolVLM, LLaVA, or Qwen-VL) to chat about your photos. Take a picture or import an image to summarize, extract text, or analyze layouts—processed 100% offline.

✨ Artifact Mode (Interactive UI Generation)
Auto-promotes LLM-generated code blocks (HTML, SVG, Python, etc.) into interactive Sandboxed UI cards. Render UI mockups, charts, or games directly inside your private chat!

💬 SQLite Local Chat History
Your chats are saved locally on your device with full Markdown rendering, LaTeX math formulas, zero-dependency syntax-highlighted code, and quick-copy buttons.

Note: Local performance is hardware-dependent. Devices with 8GB+ RAM and modern high-end processors (e.g., Snapdragon 8 Gen 3+, Dimensity 9300+) will experience significantly faster token-per-second generation.
