That sounds like a lovely little helper—like a tiny, quiet guardian for your starter. I can picture a small, clear jar with a tiny water reservoir that releases just the right amount, so you still have to stir and check it by hand but you’re never worried about it drying out. The ritual of feeding remains, and the device just takes care of the moisture, which is a nice way to keep the tradition alive while easing a bit of the practical burden. Just make sure the water level is visible so you can see when it’s low, and maybe keep a timer or a reminder note on the fridge—otherwise you might end up leaving it a day too long or overwatering it. It could be a sweet blend of old‑school baking and a little tech magic. I love the idea!
