Use it in your product

Start complete. Customize when you need to.

Components provide the fastest production path. Composables expose the same lifecycle for a UI that is entirely yours.

Vue component

Add a production summary workspace

Users can choose type, length, format and context without extra settings UI.
Vue component
<script setup lang="ts">
import { ref } from "vue";
import { Summarizer } from "@desource/browser-ai-vue";
import "@desource/browser-ai-vue/assets/lib.css";

const article = ref("Paste the article here...");
</script>

<template>
  <Summarizer v-model="article" type="key-points" format="markdown" />
</template>

Vue composable

Summarize inside your own workflow

The detailed result records token use, chunking and the final roll-up.
Vue composable
<script setup lang="ts">
import { ref } from "vue";
import { useSummarizer } from "@desource/browser-ai-vue";

const input = ref("The team shipped offline search. Next week, we will improve keyboard navigation.");
const output = ref("");
const error = ref("");
// Creating the composable in setup also registers session cleanup.
const ai = useSummarizer();
const { isProcessing, interrupt } = ai;

async function run() {
  if (isProcessing.value) return;
  output.value = "";
  error.value = "";
  try {
    if (!ai.isReady.value) {
      await ai.create({ type: "key-points", format: "markdown", length: "medium" });
    }
    const result = await ai.summarizeWithDetails(input.value, {
      autoCreate: false,
      onProgress: state => console.log(state.phase)
    });
    output.value = result.summary;
  } catch (cause) {
    if (cause instanceof DOMException && cause.name === "AbortError") return;
    error.value = cause instanceof Error ? cause.message : String(cause);
  }
}
</script>

<template>
  <textarea v-model="input" aria-label="Source text" />
  <button :disabled="isProcessing || !input.trim()" @click="run">Summarize</button>
  <button :disabled="!isProcessing" @click="interrupt">Stop</button>
  <p v-if="error" role="alert">{{ error }}</p>
  <pre>{{ output }}</pre>
</template>

One contract, native ergonomics

Use the same capability in every supported stack.

Vue composables, React hooks, Svelte stores, Angular signals, Nuxt auto-imports, and the TypeScript core all delegate browser behavior to the same tested runtime.

Vue

Vue component

Use the ready-made component or the matching use* composable.
Vue
<script setup lang="ts">
import { Summarizer } from "@desource/browser-ai-vue";
import "@desource/browser-ai-vue/assets/lib.css";
</script>

<template><Summarizer /></template>

React

React component

The matching hook exposes the same core operations for a custom interface.
React
import { Summarizer } from "@desource/browser-ai-react";
import "@desource/browser-ai-react/assets/lib.css";

export function Feature() {
  return <Summarizer />;
}

Svelte

Svelte component

Use the component or its create* controller with a readable state store.
Svelte
<script lang="ts">
  import { Summarizer } from "@desource/browser-ai-svelte";
  import "@desource/browser-ai-svelte/assets/lib.css";
</script>

<Summarizer />

Angular

Angular standalone component

Standalone components pair with signal controllers and BrowserAiService.
Angular
import { Component } from "@angular/core";
import { BrowserAiSummarizerComponent } from "@desource/browser-ai-angular";
import "@desource/browser-ai-angular/assets/lib.css";

@Component({
  standalone: true,
  imports: [BrowserAiSummarizerComponent],
  template: `<browser-ai-summarizer />`
})
export class FeatureComponent {}

Nuxt

Nuxt auto-import

The Nuxt module registers the Vue component on the client and protects SSR.
Nuxt
export default defineNuxtConfig({
  modules: ["@desource/browser-ai-nuxt"]
});

// app/pages/feature.vue
<template><Summarizer /></template>

TypeScript core

Framework-neutral controller

Start from a real click, handle browser errors, and release the native session after the result.
TypeScript core
import { createSummarizer } from "@desource/browser-ai";

const button = document.createElement("button");
const output = document.createElement("pre");
button.textContent = "Run Summarizer";
document.body.append(button, output);

button.addEventListener("click", async () => {
  button.disabled = true;
  const api = createSummarizer();
  try {
    const result = await api.summarize("The team shipped offline search. Next week, we will improve keyboard navigation.");
    output.textContent = typeof result === "string" ? result : JSON.stringify(result, null, 2);
  } catch (error) {
    output.textContent = error instanceof Error ? error.message : String(error);
  } finally {
    api.dispose();
    button.disabled = false;
  }
});
