EmailTrust

🧠 Inspiration

With the increasing number of email scams and phishing attacks, I wanted to build something simple and accessible that could help people—especially those without technical knowledge—stay safe online. I was inspired by apps like Truecaller but focused on email safety instead of phone numbers.

💡 What It Does

EmailTrust is an AI-powered email safety checker. It allows users to input:

• The sender’s email address
• The email message content

The app then:

• Checks the domain (like gmail.com or freemoney.biz) for trust level
• Scans the message content for dangerous or suspicious phrases
• Returns a result: ✅ Safe or ⚠️ Suspicious
• Provides simple safety tips for email protection

It’s built using Bolt.new, which made it possible to create this prototype without traditional coding.

🛠️ How I Built It

I used the Bolt.new no-code platform:

• Used text input fields to receive user email and message
• Built a smart AI prompt using logic for content + domain analysis
• Added clear output blocks and safety instructions

Everything was built by writing prompts — no code needed.

🚧 Challenges I Faced

• Bolt’s AI isn’t always accurate, so I had to carefully design the prompt
• It sometimes trusts safe-looking domains even when content is dangerous
• Limited customization in no-code UI design

📚 What I Learned

• How to design and test a full product using AI without code
• How to simulate cybersecurity logic in a limited AI tool
• How to write strong prompts and test UX for beginners

🔮 What’s Next

• I plan to rebuild EmailTrust using Flutter and Firebase
• I want to connect it to real-time spam-check APIs
• I’ll continue improving the AI logic and release the app for public use
• I also plan to add support for multiple languages such as Arabic, French, and Spanish
• We aim to introduce both payment options and a free trial period for users
