Sounds like you may be thinking of this site:
Our Laughing Place - Travel Wizard
FWIW, I don't think it always shows the best option. For example, if you want to go from the All Star Sports to the Boardwalk, it suggests bus to EPCOT and then Boat to BW. Doen't mention that you have to walk through EPCOT (requires admission to park) to get to the boat. As an alternative, it suggest you take the bus to Blizard Beach and then take the bus from there to the Boardwalk. Don't think the bus goes to BB all seasons and there could be a long wait at BB. It doesn't even mention what I think is the best/quickest route - take the bus to MGM and then either walk or take the boat to the BW. No park admission required and if you take the walking path, no waiting for alternate transportation.
Anyway, if you are an experienced visitor, the T Wiz will help you remember options and you will know if there are others or if it suggests one that no longer exists.
