Back in 2015 Chase added a free FICO score and credit dashboard for Chase Slate cardholders, this was a time when other card issuers were adding free FICO scores across the board but it did make sense for Chase to offer it only on this card as the Slate is specifically designed for people with bad/no credit and they are the ones most likely to be interested in credit scoring. Chase has sent out messages to Slate cardholders informing them that on June 9th, 2019 that this feature will be removed and replaced with the Chase Credit Journey instead.
Credit Journey uses a VantageScore V3 model and relies on data provided by TransUnion. FICO is more commonly used than VantageScore in actual lending decisions, although VantageScore is generally the preferred option when providing free scores (presumably because it’s cheaper).
