ContextAlert

为任意网站设置高级智能提醒。

ContextAlert is a context-based reminder extension that transforms how you monitor the web. Instead of traditional time-based reminders that interrupt you at random moments, ContextAlert creates intelligent, location-aware alerts that appear only when you visit relevant websites. The extension serves a single, focused purpose: to help users never miss important changes on their favorite pages by providing smart, context-based notifications. When you create a reminder, it doesn't just alert you at a specific time - it waits for you to actually visit the relevant website, then automatically checks if your specified conditions have been met. 🎯 Why Context-Based Reminders Are Better ❌ Traditional Method (Time-Based) Other apps tell you: "Remind me at 5 PM to buy on Amazon". The problem? The alert pops up even when you're not on Amazon, interrupting you without being able to complete the task. ✅ Our Method (Context-Based) You tell us: "When I enter Amazon, remind me to buy book X". The reminder appears automatically only when you're in the right place to act. It's like a digital post-it that appears exactly when you need it. ✨ Key Features 📝 Create Lists Instantly - Need to buy something? Make a shopping list for any online store - Have pending tasks?

Solution: Set a "When price is less than..." trigger for €80.

Solution: Create a "When text appears..." trigger for 'Buy' or 'Add to Cart'. Get notified the moment tickets go live. 📦 Stock Monitoring Problem: Your desired Amazon product shows 'Out of Stock'. Solution: Use "When text disappears..." trigger for 'Out of Stock'.
