Inspiration

Every day, millions of users spend hours browsing TikTok videos. The attention to short content is unequivocally high. Nonetheless, this also poses a challenge: how do news, science, and information show compete with music covers and comedy sketches to find a place in a world of short-form entertainment? FactCheck solves this problem by gamifying information videos to capture user attention. Through the short pop quiz, we hope to introduce a novel form of "TL;DR" for media files and deliver information in 10-15 seconds.

What it does

State-of-the-art: We adapted a state-of-the-art Generative AI model to extract the content of uploaded videos and provide a small pop quiz for users.
Extensive: The model is extensively trained to cover a wide range of topics, including but not limited to Science & Technology, Finance, Sports, Healthcare, and Politics.
Personalized: Additionally, the quiz will be provided in the user's preferred language to promote equal access to the tool.

How we built it

We used the Qwen2 model with 1.5 billion parameters to generate the quiz for the video. The model can adapt its response to a specified conversation history, enabling tailored responses and ensuring ethical constraints to generated questions.

Our application is developed using Flutter and made available on iOS 14+ operations systems, with a fastapi backend. Our model is preloaded, and generated quizzes are also cached in a Firestore (Firebase) database to enable quick access for other users.

We used TikTok Display API to get user information. This information is later used to cache responses and record answered quizzes on our database.

Challenges we ran into

Ethics of AI: How to tune the model to fit with the ethical values of AI: accuracy of information, denial of service for prohibited contents, and respect for users' privacy.
Data & Privacy: Collecting users' preferences without encroaching on their privacy.
Balancing Human & AI Expertise: How to use AI efficiently but still stay consistent with the educational intentions of the creators.

Devised a new way to access information for TikTok users
Enabled fast generation for content creators using state-of-the-art Generative AI and fast access for users using streamlined backend protocols
Bridged the gap between short-form content and educational channels.
