Ok I think I've worked it out by comparing these:

• أَنْتَ = https://www.duolingo.com/dictionary/Arabic/%D8%A3%D9%8E%D9%86%D9%92%D8%AA%D9%8E-pronoun-personal+pronoun-second+person-masculine-singular/8f7554f03292f7731486b01ae682bf90

• أَنْتِ = https://www.duolingo.com/dictionary/Arabic/%D8%A3%D9%8E%D9%86%D9%92%D8%AA%D9%90/e894f221a2c6d9b4a31c7d3ffe1e689e

• أَنْتَ = (You are (male

• أَنْتِ = (You are (female

As far as I can tell, they're pronounced the same. Sorry for the bug above. It's meant to read You are (male) and You are (female). I think it's having a hard time writing right to left and left to right at the same time.

(2anta) أَنْتَ - you (male) (2anti) أَنْتَ - you (female) The different is a suffix, "-a" and "-i" and, with that, gender
