Today, we had European elections in Germany.

We have the Wahl-O-Mat, a state-funded service, where you can answer 38 questions, and then match your positions against a selection of or all political parties that could be elected. It then shows you how much overlap (a percentage) you have with the various parties and their answers to those questions.

I find this to be a very important and useful tool for citizen information.
Campaign adverts are shallow and colorful PR. Broad slogans.
Individuals are not necessarily what the broader party policies are and how they vote. Personal sympathy can even be misleading in that a sympathetic person may not hold the values and positions you do.
Voting for a party, I think their program and stances should be the primary decision factor. (Alongside assessment of whether you can trust them of course.)
It obviously and drastically shows you misconceptions about parties and your alignment, and shows you parties relevant to you that you may not have known about before.

Do other countries have something/things like that too? A tool to match personal stance against political parties' stances? [In a concrete and up-to-date way.]
