Developer creates tool to filter and summarize urgent GitHub notifications

A developer has built a tool called GitHub Digest to address the problem of overwhelming GitHub notification feeds. The web application sorts notifications into three priority categories: those requiring immediate action, those worth reviewing, and those that can wait. It uses Google's Gemini AI to generate brief summaries for the most urgent notifications and adds explanatory labels. The tool, currently free to use, is built with Node.js, Express, and a Turso database and is hosted on Render.
