5 Free Apps to Run AI Systems Locally
Artificial Intelligence has revolutionized how we work, but relying on cloud-based, subscription-driven models like ChatGPT or Claude brings privacy concerns and recurrent costs. Fortunately, the open-source community provides powerful tools that allow you to download and run Large Language Models (LLMs) completely on your own hardware.
By running AI locally, your data never leaves your computer, you don't have to pay monthly subscription fees, and you can work without an internet connection. Here are 5 excellent, free applications to help you get started with local AI:
1. Jan
Jan is a fantastic, open-source desktop alternative to ChatGPT that runs 100% offline on your computer.
