MetaSearch Project | Windows Desktop Application
Search trusted medical sources from one place.
MetaSearch is a Windows desktop application designed for healthcare professionals, researchers, and students who need fast, transparent access to multiple trusted medical and scientific sources.
Unlike AI-powered search engines, MetaSearch does not generate answers. Instead, it helps you access original scientific sources quickly and directly.
One fixed price. No per-search charges, no usage limits, and no unexpected bills. Some external sources may require their own institutional or personal subscription.
Below, you can download a fully functional 30-day trial version of MetaSearch.
Privacy matters!
No search history. No tracking. No profiling!
Only your first name, last name, email address, and a SHA-256 hash of your machine identifier are stored in our database to validate your license.
Your MetaSearch version is also stored so that we can provide faster support if you ever need assistance.

Windows 10 / Windows 11 • 30-day fully functional trial (Windows setup file .exe)
MetaSearch will probably display a Windows SmartScreen warning the first time you launch it.
This does not mean that the application is unsafe.
It simply means that I have not yet built enough reputation as a software developer for Windows SmartScreen.
If you wish, feel free to scan the installer with your antivirus before running it.
