How to create a simple phishing detection and awareness system

I am a beginner student working on a mini project about a "Phishing Detection and Awareness System".

I want to create a simple system that can:

- Check whether a URL is safe or suspicious

- Alert the user if the link is phishing

I am not using advanced machine learning. I prefer a simple method using basic programming (Python or JavaScript).

Can anyone suggest:

Simple techniques to detect phishing URLs?

Any beginner-friendly approach or example code?

What features should I include in a basic project?

Thank you.
