Chat Input Box

A fully responsive chat input component built with React, TypeScript, and Tailwind CSS. Modeled after modern AI chat interfaces, it auto-grows with content, adapts cleanly across breakpoints, and keeps its toolbar anchored without ever spilling outside its own bounds.

Key features

1. Auto-resizing textarea

The input grows line by line as the user types, capped at a maximum height, then scrolls internally rather than pushing the rest of the layout around. Height resets cleanly when the field is cleared.

2. Overflow-safe container

Built on min-height rather than fixed height, so the card always expands to fit the textarea and toolbar together no clipped buttons, no content escaping the rounded card, at any screen size.

3. Mobile-first responsive layout

The credits/premium bar collapses out of view on small screens while the input and its toolbar remain fully usable, with icon buttons protected from being squeezed or hidden as space tightens.

4. Icon toolbar

Attachment, click-to-select, and voice-input actions sit on one side; a send button that enables only once there's real content sits on the other spaced to stay legible from mobile up to desktop.

5. Composable by design

Ships as a single selfcontained component, so it can be dropped into any page shell a landing page, a dashboard, or a full chat interface without extra wiring.
