WalkCast — Screen-Free Audio Digest for Outdoor Walks
This is a submission for the Hacktoberfest Open-Source AI Challenge Week 1: Touch Grass What I Built WalkCast is a 100% offline, screen-minimizing audio web app that ingests long-form articles, tech news, and newsletters, converting them into a warm, conversational podcast script.

This project, known as WalkCast, is an open-source audio digest app created specifically for outdoor walks. The app takes long-form articles, tech news, and newsletters, and transforms them into a warm, conversational podcast script. Users can generate the audio digest and listen to it while walking outside, without needing to look at their phone screen.
WalkCast operates as a privacy-first, offline tool that runs local Llama 3.2 inference on the user's browser. This means it does not rely on a hosted backend and all processing occurs locally. The app does not require a cellular data connection or any cloud-based API subscriptions, making it completely free to use and environmentally friendly.
The code for WalkCast can be accessed by simply opening the walkcast.html file in any web browser that has local Ollama running. The app fetches the conversational podcast script from the local Llama 3.2 instance, which then uses the native browser SpeechSynthesis API to play back the audio digest at a relaxing walking pace of 0.95x. The user interface is designed with a cozy, storybook street aesthetic that matches the theme of stepping outside and enjoying the outdoors.
