I (er Claude) wrote an RSS de-duper

Help me test it!

Upload your OPML RSS feed file, then subscribe to the new "aggregated" RSS feed with all of your articles in it, but you only hear about the new Apple phone once, not 87 different times!

100% free to use.

No accounts, passwords or signups required.

Nice project. Duplicate stories across different RSS feeds are a real pain.

I'm curious that how are you deciding that two feed items are the same story without dropping a distinct news?
