After some back and forth with our design team, I refined the AI input field to be more fluid and responsive. Rather than static transitions, I added subtle animations that make the interaction feel more natural - the input grows with content, the mic button slides, and the submit button fades in when you start typing.
We kept the implementation relatively straightforward, using React's built-in state management and refs to handle the auto-expanding textarea. The mic and submit buttons position themselves dynamically based on the input state, with smooth transitions handling their movement. Dark mode support comes built-in through Tailwind's dark variants, making it easy to maintain across themes.
