These two solve different problems. Al Ansari is a physical exchange house that says it has 280+ branches in the UAE — you can walk in, hand over cash, and have someone collect cash on the other end. Wise has no branches at all; everything happens in the app, and the money only ever moves bank-to-bank.
The pricing philosophy differs just as much. Al Ansari charges a modest flat fee on popular corridors with the exchange-rate margin layered on top and widening on less common currencies. Wise says it skips the margin and uses the mid-market rate, charging an explicit percentage fee instead, which varies by currency. For a UAE resident, though, the bigger difference right now is availability: Wise's UAE send-money pages show a waitlist, and its Help Centre says paying for transfers in AED isn't supported except with money already held in a Wise account.
