Threadist is your personal storyteller, making it effortless to consume captivating Reddit content while multitasking or relaxing.

How we built it

We built Threadist as a robust and modern multi-platform application, leveraging a powerful and complementary tech stack to deliver a seamless user experience.

Frontend

The mobile application was developed using React Native with Expo, allowing us to efficiently target both iOS and Android from a single codebase. This approach ensures a consistent and high-quality user experience across devices. We used TypeScript for enhanced code quality and maintainability, benefiting from its type safety features. For smooth audio playback, we integrated Expo AV. The user interface was meticulously designed to be Spotify-like, prioritizing a beautiful, modern aesthetic and intuitive navigation.

Backend

Our backend is powered by FastAPI, a high-performance Python web framework, chosen for its speed, asynchronous capabilities, and developer-friendly design. This ensures our API is fast, responsive, and easy to build upon. We integrated ElevenLabs for its cutting-edge AI text-to-speech capabilities, which deliver incredibly natural and diverse narration voices, bringing stories to life. Supabase serves as our comprehensive backend-as-a-service solution, managing secure user authentication (signup and login) and providing our PostgreSQL database for user interests and story data. Reddit content is dynamically pulled directly from the Reddit API. To enhance performance and responsiveness, Redis is utilized for caching frequently accessed data and managing background tasks, ensuring rapid story loading and smooth audio generation.

Challenges we ran into

Developing Threadist presented a few exciting challenges that pushed our technical capabilities:

  • Optimizing AI Narration for Scale: Converting potentially very long Reddit threads into natural-sounding audio efficiently, while managing ElevenLabs API rate limits and ensuring a seamless user experience, required careful design around text chunking and asynchronous processing.
  • Efficient Audio Storage and Delivery: Handling the storage and streaming of a large number of generated audio files to mobile clients posed a challenge. We had to optimize file sizes and delivery methods to ensure quick loading times and minimize user data consumption.
  • Complex Multi-API Integration: Seamlessly integrating three distinct external APIs (Reddit for content, ElevenLabs for TTS, and Supabase for authentication/database) and ensuring robust data flow, error handling, and security across them was an intricate task requiring meticulous attention to detail.
  • Cross-Platform UI Consistency: Maintaining a consistent and high-quality user interface and experience across both iOS and Android platforms using React Native, especially with dynamic content and audio playback, demanded careful testing and platform-specific adjustments.
