inte sant

inte (“not”) +‎ sant (“true”)

inte sant

1. Used to ask for agreement with (or confirmation of) a statement; isn't it?, right?, isn't that so?, etc.

   – Jag tror han begick mordet. – Men han var ju på andra sidan jorden, inte sant?

   – I think he committed the murder. – But he was on the other side of the world, right?

   – Du fick svart. – Det passar ju bäst så, inte sant?

   – You got black. – That's the most fitting, isn't it? (from Antonius Block playing chess against Death in The Seventh Seal)

Indicates somewhat stronger expectation that the listener will agree compared to eller hur (and so can function as a kind of reminder), though the difference is subtle.
