Unfortunately, keeping it indoors won't do it any good - Rosemary is a mediterranean herb, so it expects to be cold or very cool in winter, and have hot summers. It likes full sun exposure, regardless of the time of year, and does best in free draining, gritty soil. It does need watering, but watering well when its in a pot, with any excess allowed to drain away freely (none left in an outer tray or pot after 30 minutes), and only water when the surface of the soil feels just about dry to the touch. It's hard to tell whether this was a watering issue, poor drainage, damage to the roots when it was potted up, or simply being kept indoors.
If its gone crispy this morning, it may be a goner, but just scrape back the surface of the bark with a fingernail near the base - if that's still moist, it may recover, but move it somewhere as cool as you can possibly manage, preferably in a spot with sun.
