Snoopy

Inspiration

With online scams becoming increasingly prevalent, especially with the adaption of AI by malicious actors, we decided to build an extension that'll make fact-checking your social media posts available at the click of a button.

What it does

Snoopy provides an in-built verification of each post on Facebook.com, alerting users of potential scam posts, providing the estimated factual accuracy of each post's claims, and flagging AI-generated images.

How we built it

We built a chrome extension using Vanilla Javascript with calls to the OpenRouter API for post fact-verification, and the SightEngine API for detecting AI-generated images.

Challenges we ran into

We struggled with scraping necessary data from the Facebook website, as the HTML structure of the website was somewhat disorganized and therefore difficult to handle consistently between posts. We also needed to experiment with various prompts and OpenRouter models to find the correct balance between speed and accuracy.

Accomplishments that we're proud of

We're especially proud of our accuracy meter, as well as the correct medical information suggestions in the case of our program spotting medical misinformation.

What we learned

We all learned the process behind building Chrome extensions and became a lot more knowledgeable about the extent to which misinformation is prevalent on Facebook.

What's next for Snoopy

Our original motivation for Snoopy was very much centered on concern for medical misinformation on the internet, so a big feature we'd love to implement in the future would be a background check on accounts posting medical information, so that users can know if the people they're receiving advice from have the proper certifications and qualifications to speak on such important topics.
