Artificial intelligence tools are powerful, but many of them require sending your data to the cloud. This raises privacy concerns, especially for professionals, businesses, and freelancers handling sensitive information. That’s where local AI tools like Ollama come in. They allow you to run AI models directly on your computer, keeping your data private and secure.

In this guide, you’ll learn how to use local AI with Ollama, its benefits, setup process, and whether it’s right for your workflow.
