Fenn

Fenn is a powerful file search engine for macOS that helps you find exactly what you need, whether it's inside videos, audio files, PDFs, or more. It's 100% local, with no privacy trade-offs.

I built Fenn out of frustration with Spotlight’s poor performance. Now, with Fenn, you can finally search inside your files and actually find what you're looking for, fast. So next time you’re stuck thinking, “I know I saw that somewhere…” 
You’ll find it in seconds.
