How to Run AI Locally with Ollama (Step-by-Step)
ollama run llama3 — and you have a private AI assistant running offline on your own laptop, completely free. No API key, no subscription, no data sent to any company.Running AI locally means the model lives on your computer instead of a company's server. It works offline, keeps your data 100% private, and costs nothing per month. Ollama is the simplest free tool to do this — it handles downloading, running and chatting with open-source models in a single command.
Step 1: Download Ollama
Go to ollama.com and download the installer for your OS — Windows, macOS or Linux.
Step 2: Install it
Run the downloaded installer like any normal app. Ollama runs quietly in the background and adds the ollama command to your terminal.
Step 3: Verify the install
Open your terminal and check the version to confirm it works.
# Linux one-line install
curl -fsSL https://ollama.com/install.sh | sh
# Check Ollama is installed (all platforms)
ollama --versionUse ollama run followed by a model name. The first time, it downloads the model (a few GB); after that it runs instantly and offline.
# Download and chat with Llama 3 (general purpose)
ollama run llama3
# A smaller, faster model for low-RAM laptops
ollama run mistral
# Better Hindi / multilingual support
ollama run qwen
# Type your question, e.g. 'Explain photosynthesis in simple Hindi'
