WhenX: Semantic Alerts That Track Web Answer Changes

WhenX turns any question into a smart alert, scanning the web and pinging you the moment the answer changes.

Overview

WhenX reimagines how we monitor information online by letting you ask a question in plain language instead of hunting for a specific webpage or keyword to track. Once you submit your question, WhenX searches the web to find a current answer, then continuously monitors that answer for changes over time. Rather than refreshing pages or setting up complicated scrapers, you simply describe what you want to know and let WhenX handle the rest. This approach, which the creators call 'Semantic Alerts,' is especially powerful because it understands the meaning behind your question rather than just matching static text. Whether you're waiting for a favorite author's next release, a new job posting, or a product launch, WhenX watches the underlying answer and flags it the moment something shifts. Alerts can be delivered through email, SMS, or Discord, making it easy to stay informed wherever you already spend your time. Built as an open-source personal project, WhenX offers a refreshingly simple three-step workflow: write your question, test it to confirm accuracy, and deploy it to start receiving notifications. It's a lightweight yet clever solution for anyone who needs to keep tabs on ever-changing information across the web without manually checking back.
