Building an AI-Powered Laravel + MongoDB App
A Walkthrough Using Laravel Boost
This tutorial shows how to build a modern AI-enabled app using:
-
⚡ Laravel 11
-
🍃 MongoDB
-
🤖 OpenAI API (for AI features)
-
🚀 Laravel Boost (for AI-assisted development)
We’ll build a simple AI Knowledge Base App where:
-
Users submit content
-
AI generates summaries
-
Data is stored in MongoDB
-
AI responses are cached and reusable
Step 1: Install Laravel 11
composer create-project laravel/laravel ai-mongo-app
cd ai-mongo-app
Step 2: Install MongoDB in Laravel
Laravel doesn’t support MongoDB natively, so we install the MongoDB driver:
composer require mongodb/laravel-mongodb
Update .env
DB_CONNECTION=mongodb
DB_HOST=127.0.0.1
DB_PORT=27017
DB_DATABASE=ai_app
DB_USERNAME=
DB_PASSWORD=
Update config/database.php
'default' => env('DB_CONNECTION', 'mongodb'),
Step 3: Create MongoDB Model
Unlike SQL, MongoDB uses collections instead of tables.
php artisan make:model Article -m
Update Article.php:
use MongoDB\Laravel\Eloquent\Model;
class Article extends Model
{
protected $connection = 'mongodb';
protected $collection = 'articles';
protected $fillable = [
'title',
'content',
'summary',
'ai_embedding'
];
}
No traditional migrations needed unless you want validation structure.
Step 4: Add OpenAI Integration
Install HTTP client if needed:
composer require guzzlehttp/guzzle
Create a service:
php artisan make:service OpenAIService
app/Services/OpenAIService.php
namespace App\Services;
use Illuminate\Support\Facades\Http;
class OpenAIService
{
public function summarize($text)
{
$response = Http::withToken(env('OPENAI_API_KEY'))
->post('https://api.openai.com/v1/chat/completions', [
'model' => 'gpt-4o-mini',
'messages' => [
['role' => 'user', 'content' => "Summarize this: ".$text]
],
]);
return $response['choices'][0]['message']['content'] ?? null;
}
}
Add in .env:
OPENAI_API_KEY=your_key_here
Step 5: Store AI Summary in MongoDB
Create controller:
php artisan make:controller ArticleController
use App\Models\Article;
use App\Services\OpenAIService;
public function store(Request $request, OpenAIService $ai)
{
$summary = $ai->summarize($request->content);
Article::create([
'title' => $request->title,
'content' => $request->content,
'summary' => $summary,
]);
return back()->with('success', 'AI summary generated!');
}
Now every article automatically gets an AI-generated summary.
Step 6: Using Laravel Boost for Faster Development
Laravel Boost helps you:
-
Generate models instantly
-
Create controllers with AI prompts
-
Generate test cases
-
Refactor code intelligently
-
Create API resources quickly
Example AI Prompt inside Boost:
Generate a RESTful API for Articles with pagination, filtering, and search.
Boost will auto-generate:
-
Controller
-
Resource class
-
API routes
-
Validation rules
-
Feature tests
Huge productivity gain 🚀
Step 7: Add AI Embeddings (Advanced Feature)
For semantic search:
-
Generate embeddings from OpenAI
-
Store vector inside MongoDB
-
Use vector search (MongoDB Atlas)
Modify OpenAI service:
public function embedding($text)
{
$response = Http::withToken(env('OPENAI_API_KEY'))
->post('https://api.openai.com/v1/embeddings', [
'model' => 'text-embedding-3-small',
'input' => $text,
]);
return $response['data'][0]['embedding'] ?? [];
}
Store in MongoDB:
'ai_embedding' => $embeddingArray
Now you can implement:
-
AI-powered search
-
Recommendation system
-

Best Practices
✔ Cache AI responses
✔ Queue AI requests (don’t block request lifecycle)
✔ Use Laravel Queues
✔ Rate-limit API calls
✔ Validate input length
✔ Log AI failures

When to Use MongoDB Instead of MySQL?
Use MongoDB when:
✔ You need flexible schema
✔ You store AI vectors
✔ You handle JSON-heavy data
✔ Rapid prototyping
✔ Large text content
Use MySQL when:
✔ Strong relational data
✔ Complex joins
✔ Traditional business systems
Final Thoughts
Laravel + MongoDB + AI is powerful for:
-
SaaS apps
-
AI startups
-
Automation tools
-
Smart dashboards
Using Laravel Boost dramatically speeds up development and testing.
