Care that speaks first.

Nova catches medication mistakes before they happen and spots the patterns a family would miss, like a dose change followed by new dizziness. It connects Rose's Echo, her daughter's Echo and the Ring doorbell at her front door.

It sees what's in her hand.

Rose's knee hurts and she reaches for ibuprofen. She holds the bottle up to her Echo Show. Amazon Nova reads the label, and Nova checks it against her medication plan and her doctor's notes.
