Are there any generic tools/apps that allow you to search for a specific hotel and see the lowest prices over a given period?

For example if I go to the Premier Inn website in the UK I can enter the area I would like to stay and the date and select flexible. It will then show me nightly prices for the hotels on a week by week basis.

What I would find really useful is if you could do this for any hotel on a hotel agnostic website. So for example you could request the lowest price for Le Bristol hotel in Paris for January.
