🚀 Build an AI Teacher Tool with Laravel (Step-by-Step Guide)

📌 Overview

In this tutorial, we will build an AI-powered backend using Laravel and OpenAI that:

• Accepts lesson content
• Cleans and structures it
• Generates:
  • Simplified version
  • Glossary
  • Quiz

---

🧱 Step 1: Create Laravel Project

composer create-project laravel/laravel ai-teacher
cd ai-teacher

Run server:

php artisan serve

---

🔐 Step 2: Install OpenAI PHP SDK

composer require openai-php/client

---

⚙️ Step 3: Setup API Key

.env

OPENAI_API_KEY=your_api_key_here

---

config/services.php

'openai' => [
    'key' => env('OPENAI_API_KEY'),
],

---

🧠 Step 4: Create AI Service

📁 app/Services/AIService.php

<?php

namespace App\Services;

use OpenAI;

class AIService
{
    protected $client;

    public function __construct()
    {
        $this->client = OpenAI::client(config('services.openai.key'));
    }

    public function generate($prompt)
    {
        $response = $this->client->chat()->create([
            'model' => 'gpt-4.1-mini',
            'messages' => [
                ['role' => 'system', 'content' => 'You are an expert educational assistant.'],
                ['role' => 'user', 'content' => $prompt],
            ],
            'temperature' => 0.7,
        ]);

        return $response->choices[0]->message->content;
    }
}

---

✍️ Step 5: Create Prompt Service

📁 app/Services/PromptService.php

<?php

namespace App\Services;

class PromptService
{
    public static function clean($text)
    {
        return <<<PROMPT
Clean and structure this educational content.

- Keep meaning same
- Fix grammar
- Remove noise
- Keep poem/story format

Content:
"""
$text
"""
PROMPT;
    }

    public static function simplify($text)
    {
        return <<<PROMPT
Simplify this for Grade 5 students.

- Use simple words
- Short sentences

Content:
"""
$text
"""
PROMPT;
    }

    public static function glossary($text)
    {
        return <<<PROMPT
Extract important words and meanings.

Format:
Word → Meaning

Content:
"""
$text
"""
PROMPT;
    }

    public static function quiz($text)
    {
        return <<<PROMPT
Create:
- 3 MCQs
- 2 short questions

Content:
"""
$text
"""
PROMPT;
    }
}

---

🎯 Step 6: Create Controller

php artisan make:controller AIController

---

📁 app/Http/Controllers/AIController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Services\AIService;
use App\Services\PromptService;

class AIController extends Controller
{
    protected $ai;

    public function __construct(AIService $ai)
    {
        $this->ai = $ai;
    }

    public function process(Request $request)
    {
        $text = $request->input('content');

        // Step 1: Clean
        $clean = $this->ai->generate(
            PromptService::clean($text)
        );

        // Step 2: Simplify
        $simplified = $this->ai->generate(
            PromptService::simplify($clean)
        );

        // Step 3: Glossary
        $glossary = $this->ai->generate(
            PromptService::glossary($clean)
        );

        // Step 4: Quiz
        $quiz = $this->ai->generate(
            PromptService::quiz($clean)
        );

        return response()->json([
            'original' => $clean,
            'simplified' => $simplified,
            'glossary' => $glossary,
            'quiz' => $quiz,
        ]);
    }
}

---

🌐 Step 7: Add Route

📁 routes/api.php

use App\Http\Controllers\AIController;

Route::post('/ai/process', [AIController::class, 'process']);

---

📤 Step 8: Test API

Use Postman or curl:

POST /api/ai/process

{
  "content": "Today our papa is searching everywhere..."
}

---

📊 Sample Response

{
  "original": "...",
  "simplified": "...",
  "glossary": "...",
  "quiz": "..."
}

---

⚡ Step 9: Improve Performance (Important)

✅ Add Caching

use Illuminate\Support\Facades\Cache;

$clean = Cache::remember(md5($text), 3600, function () use ($text) {
    return $this->ai->generate(
        PromptService::clean($text)
    );
});

---

✅ Use Queue (Async)

php artisan queue:work

Move AI calls into Jobs to avoid slow responses.

---

🌍 Step 10: Add Language Support

Modify prompt:

public static function simplify($text, $lang = 'English')

Then pass:

• English
• Arabic
• Hindi

---

🧩 Step 11: Add Instruction Modes

Example:

Mode: step-by-step / analogy / real-life examples

Append inside prompt.

---

🚀 Final Architecture

Frontend (Flutter / React)
        ↓
Laravel API
        ↓
AI Service (OpenAI)
        ↓
Prompt Pipeline
        ↓
Structured Output

---

💡 Pro Tips (From Real Projects)

• Don’t send raw PDF → extract text first
• Always clean content before processing
• Use multiple prompts instead of one
• Cache everything to reduce cost
• Start simple → scale later

---

✅ Final Result

You now have:

• AI-powered backend ✔
• Structured content generation ✔
• Scalable Laravel architecture ✔
• MVP-ready system ✔

---

If you want next, I can:

• Add PDF upload + text extraction
• Build Flutter UI
• Or convert this into a SaaS product (login, billing, etc.)
