It's a clean sentence but doesn't make more sense. The screenshots fill in the blanks for me, as in it looks like you rebuilt Google Alerts with additional features for finding that content again later (tagging, notes).
If we were talking face to face and you said "This is the easiest way to find quality content" I'd follow it up with "what kind of content?" and "what problems do I have now in finding content?". I'd say "What problem of mine are you solving?" And the answer to that last question should be your tagline.
