Introduction & Context
The rise of AI APIs like OpenAI's GPT and Hugging Face Transformers has opened a new frontier for frontend developers. Today, you can enrich your Vue apps with AI-driven features—without being a machine learning expert.
This tutorial walks you through building an AI-powered UI component in Vue 3. You'll learn how to connect to an AI API, handle user input, display responses, and create a polished, interactive user experience.
Whether you're working on chatbots, intelligent writing assistants, or form enhancers, this post is for you.
Goals and What You’ll Learn
By the end of this article, you’ll learn how to:
- Integrate OpenAI’s API into a Vue 3 project
- Build a smart text component that suggests improved phrasing
- Handle async requests and loading states with good UX
- Apply responsive, accessible design to AI interfaces
The Project: AI Writing Assistant
We’ll build a smart textarea component. Users write a sentence, and the AI suggests a more professional or grammatically improved version.
Stack
- Vue 3 with
<script setup>and Composition API - Axios for API requests
- OpenAI API (you’ll need an API key)
- Tailwind CSS (optional for styling)
Setup the Project
Install Vue 3 via Vite:
npm create vite@latest ai-text-suggester -- --template vue
cd ai-text-suggester
npm install
npm install axios
Add your OpenAI key to an .env file:
VITE_OPENAI_KEY=your_api_key_here
Build the AITextSuggester.vue Component
<template>
<div class="max-w-xl mx-auto p-4">
<textarea v-model="inputText" placeholder="Write something..." class="w-full p-2 border rounded" rows="5" />
<button
:disabled="loading || !inputText"
@click="generateSuggestion"
class="mt-2 bg-blue-600 text-white py-2 px-4 rounded disabled:opacity-50"
>
{{ loading ? 'Generating...' : 'Improve Writing' }}
</button>
<div v-if="suggestion" class="mt-4 p-4 border rounded bg-gray-50">
<strong>Suggested:</strong>
<p>{{ suggestion }}</p>
</div>
</div>
</template>
<script setup>
import { ref } from 'vue'
import axios from 'axios'
const inputText = ref('')
const suggestion = ref('')
const loading = ref(false)
const generateSuggestion = async () => {
if (!inputText.value.trim()) return
loading.value = true
suggestion.value = ''
try {
const response = await axios.post(
'https://api.openai.com/v1/chat/completions',
{
model: 'gpt-3.5-turbo',
messages: [
{ role: 'system', content: 'You are a helpful writing assistant that improves clarity and grammar.' },
{ role: 'user', content: `Improve this sentence: ${inputText.value}` }
]
},
{
headers: {
Authorization: `Bearer ${import.meta.env.VITE_OPENAI_KEY}`
}
}
)
suggestion.value = response.data.choices[0].message.content.trim()
} catch (error) {
console.error('Error generating suggestion:', error)
suggestion.value = 'Something went wrong. Please try again.'
} finally {
loading.value = false
}
}
</script>
Accessibility and UX Considerations
- Disabled button state ensures user can’t spam the API.
- Loading text gives feedback on current action.
- Clear separation of input and response aids comprehension.
💡 Tip: Use aria-live="polite" on the suggestion div for screen reader accessibility.
Further Enhancements
- Add speech-to-text input support using the Web Speech API.
- Show AI confidence score or alternate suggestions.
- Store suggestion history locally.
- Animate loading states or add skeleton loaders.

Summary and Conclusion
You just built a functional, polished AI-enhanced component using Vue 3 and OpenAI’s API. With just a few lines of code, we turned a regular textarea into a smart assistant that improves user writing.
This is just the beginning—imagine applying similar principles to form validators, chatbot interfaces, or document generators.
