💡 Inspiration

More than one billion people on Earth will travel the country each year, visiting many new and exciting places while on the adventure of a lifetime. Although traveling enables individuals to learn more about the rich culture, history, and background of those living in different cities, states, and countries, some experiences are much safer than others. Sadly, some areas have more significant risks, such as Jamaica, where human trafficking and kidnapping occur daily.

The Safe App uses the Expert A.I. Sentiment Analysis Model to see how safe the current location of the user is.

The app does that by:

  • Geocoding the user's current location to find their current address.
  • Articles on relevant news are found and parsed with web scraping.
  • The Document Analysis and Sentiment Analysis Model process each of the articles.
  • The Safety Index for the location is calculated based on the average sentiment score for all the results combined.

🚀 How we built it

  • Flutter - was used to create the user interface.
  • Google Maps Geocoding API - was used to find the current address.
  • Google Maps API was - used to display the map in the app.
  • Expert A.I.- was used for the Sentiment Analysis and Document Analysis for the topics.
  • Python - was used for the backend of the application.
  • AWS Amplify - was used for the profile management.
  • AWS Lambda - was used for the backend.

Challenges we ran into 🤬

Working with the brand new APIs from Expert A.I. APIs were entirely new for me at this hackathon. Learning it was challenging at the start but very fun. The playground made it easier to understand at: https://try.expert.ai/.

Accomplishments that we're proud of ⭐

  • We created a functional, helpful prototype of a great app in one month that can help people stay safe and save lives.
  • We spent a lot of time working on a simple user experience and a beautiful user interface.

What's next for The Safe App

  • Launching the Safe App on both app stores (pending)
  • The ability to show the safest location closest to the current area.
  • User acceptance testing on the prototype.
