You can look at a door shoe.
They come in brown too. Any hardware store with any normal amount of stock will have one like it. If you drill the holes correctly, you can adjust it slightly downward if/when the door shifts in the frame.
Just measure the gap, and buy one that claims to cover gaps of that size.
I put a white one of the above product on my back door with your same problem, and it's holding up nicely after 2 months. It's all plastic. They had metal shoes that were more expensive that may or may not be more durable. You're looking at $10-20 max. Either one will resolve your bottom draft immediately.
Edit: Bonus is that it also protects the bottom edge of the door from splintering/chips/wear.
