LocalAI: Offline AI Chatbot

LocalAI is a 100% offline AI chatbot that runs open-source LLM models directly on your phone. No internet. No account. No cloud. Your chats, prompts and photos never leave your device.

Turn your Android phone into a private AI assistant that works on a plane, on the metro, in the mountains, anywhere with zero signal.

🔒 PRIVATE AI, 100% ON-DEVICE
• Offline AI chat: every word is generated locally by an optimized llama.cpp engine
• No sign-up, no API key and no subscription needed to start
• Your conversations are never uploaded or used for training
• Airplane-mode proof: an offline AI assistant that keeps your data on your phone

🧠 BUILT-IN AI MODEL HUB (GGUF)
Download, switch and manage open-weight LLM models, sized for real phones from 3GB RAM budget devices to flagships:
• Llama 3.2 1B & 3B Instruct
• Gemma 2 2B Instruct
• Qwen2.5 0.5B & 1.5B Instruct
• Phi-3 Mini & Phi-3.5 Mini Instruct
• DeepSeek R1 Distill Qwen 1.5B
• SmolLM2 360M & 1.7B Instruct
• TinyLlama 1.1B Chat
Every model card shows file size, RAM requirement and what the model is good at, so you never download an AI model your phone cannot run.

🖼️ OFFLINE VISION AI: CHAT WITH IMAGES
Attach a photo, screenshot or diagram and ask questions about it, processed 100% offline:
• SmolVLM 500M, SmolVLM2 256M & 500M for fast image description
• Gemma 3 4B Vision for high-quality image understanding on flagship phones
Describe photos, read text in images and explain screenshots and charts with no internet.

💻 OFFLINE CODING ASSISTANT

⚡ WHAT PEOPLE USE LOCALAI FOR
• Offline AI writer: emails, essays, captions, rewrites and grammar fixes
• Offline AI summarizer: turn long text into clear key points
• Offline AI translator for travel with no roaming or WiFi
• Offline study helper: explanations, quizzes and revision notes
• Private journaling, brainstorming, roleplay and story writing
• Coding help on a train, a plane or a remote site with no signal

📱 DEVICE REQUIREMENTS
• 3–4GB RAM: light models (SmolLM2 360M, Qwen2.5 0.5B, SmolVLM2 256M)
• 6–8GB RAM: balanced models (Gemma 2 2B, Llama 3.2 3B, Phi-3.5 Mini)
• 10GB+ RAM: Qwen2.5 Coder 7B and Gemma 3 4B Vision
• Storage: roughly 300MB to 5GB per model
Speed depends on your hardware. Phones with Snapdragon 8 Gen 2+ or Dimensity 9000+ generate text noticeably faster. The first run of a model is slower while it loads into memory.

LocalAI is an offline AI app, a local AI chatbot and an on-device AI assistant in one: run LLM models offline, chat with AI without internet, and use private AI for writing, summarizing, translation, study, coding and image analysis.
