avai is a free, open-source security scanner that runs entirely on your computer. It inspects the directories, processes, and system locations where malware typically hides, then passes the findings to a local AI model that explains in plain English whether anything looks dangerous. No security expertise required — instead of cryptic alerts and hash codes, you get a clear explanation of what was found and why it might matter. Because the analysis stays on-device, your files and system data are never sent to an external server. Aimed at everyday Windows users who want a second opinion on their machine without paying for a subscription or handing their data to a cloud service.
