Prompt Bar

A prompt box that grows as you type, with attachments, a model menu, an approval toggle and a mic that opens into a live level meter, plus a send button that only lights up when there's something to send.

npx shadcn@latest add https://devl.dev/r/prompt-bar.json

Use it

Import it and render it. Every prop has a typed default, so it works straight away, and you pass your own data when you’re ready.

import { PromptBar } from "@/components/prompt-bar";

export default function Page() {
  return <PromptBar />;
}

Streamed Reply

An answer that reads its sources first, then softly streams in word by word, with little numbered chips you can hover to peek at each source, all in a card that holds its size the whole time.

Footnoted Answer

An answer whose footnotes really point somewhere: hover a number and its sentence lights up in the source's colour, click it and the quoted passage unfolds with the matching words marked.

Reply Toolbar

The quiet row under an AI reply where every small action gives something back: copy draws a check, regenerate opens a version switcher, a thumb asks what worked and read aloud turns into an equaliser.

Model Switcher

A model menu that helps you choose: hover a model to compare speed, quality and cost, turn on thinking to set the effort, and watch latency and price count to their new values, inline or from a pill trigger.
