Sieve - filter webpages and watch changes

In plain words

Sieve is a tool that filters webpages and monitors them for changes. Users can set up watches on specific web content and receive notifications when updates occur. The service is designed for anyone who needs to track changes on websites without manually checking them repeatedly. It launched in May 2013 and serves as a practical solution for staying informed about webpage modifications in real time.
