This is a submission for the Redis AI Challenge: Beyond the Cache.

What I Built

Voice News Summary solves a common problem: information overload. Reading through dozens of articles every day can be time-consuming, and not everyone has time to skim long news posts. This app lets users type any topic, get an AI-generated summary of the latest news, and listen to it immediately.

Key Features

• AI-Generated Summaries: Uses OpenAI GPT to produce concise, high-quality summaries.
• Text-to-Speech Output: Converts summaries to natural-sounding voice with ElevenLabs TTS.
• Redis Caching: Speeds up subsequent requests by storing summaries and audio URLs in Redis.
• Serverless Deployment: Built on Next.js and deployed on Vercel for fast, scalable delivery.
• Clean UI: Built with TailwindCSS for a minimal and responsive design.

Tech Stack

• Frontend: React 19 with Vite, TailwindCSS
• AI APIs: Google Generative AI (for summarization)
• Database & Cache: Redis using ioredis for connection and caching
• Deployment: Vercel (for frontend) + Redis Cloud (for caching & vector storage)

Demo

Live Demo: https://voice-news-summary.vercel.app

Type any topic, get AI-generated summaries, and listen to them instantly.

How I Used Redis 8

Redis powers the core experience:

• Caching Summaries: Once an article summary is generated and converted to audio, it’s stored in Redis for fast future retrieval.
• Redis Vector Sets: Planned future upgrade for semantic search, allowing related news retrieval beyond exact keyword matching.
• Real-time Speed: With Redis Cloud, the app responds in milliseconds, even when handling multiple concurrent requests.

Why It Matters

In a world of information overload, Voice News Summary makes news consumption:

• Faster: Get to the core of a story in seconds.
• Accessible: Listen to summaries instead of reading long text.
• Scalable: Uses AI + Redis to deliver near-instant response times.

What’s Next

• Vector Search: Use Redis Vector Sets for semantic search and related topic discovery.
• Personalized Feeds: Customize summaries and voices based on user preferences.
• Mobile PWA: Turn this into a progressive web app for on-the-go usage.
