I'm sharing a tool here that I found quite useful for streamlining the reconnaissance and OSINT phase. It’s a website that automates the creation of complex Google Dorks.
Basically, it allows you to enter a domain and instantly generate searches to find PDF files, login panels, exposed directories (index of), or configuration files.
It is Open Source and static (you can check the code on GitHub).
It automatically cleans URLs before sending them to Google.
