Laravel AI Form Validator

🚀 Use AI to validate free-text form inputs beyond normal Laravel validation rules.
Powered by matrixbrains/laravel-ai.

---

Installation

composer require matrixbrains/laravel-ai-form-validator

This package depends on matrixbrains/laravel-ai, which acts as the AI wrapper.

---

Configuration

Publish the config:

php artisan vendor:publish --provider="Matrixbrains\\LaravelAiFormValidator\\LaravelAiFormValidatorServiceProvider" --tag=config

AI Environment Setup

Make sure you have configured Laravel AI correctly in your .env file.
You need to define which AI driver to use and provide its API key.

Example .env:

# Choose AI driver (openai, gemini, claude)
AI_DRIVER=openai

# OpenAI
OPENAI_API_KEY=your-openai-key

# Google Gemini
GEMINI_API_KEY=your-gemini-key

# Anthropic Claude
ANTHROPIC_API_KEY=your-claude-key

By default, AI_DRIVER=openai will be used.
You can switch drivers at any time.

Usage

$request->validate([
    'feedback' => 'required|ai_appropriate',
    'company_name' => 'required|ai_custom:"Check if this looks like a real company name"',
]);

---

Built-in AI Rules

• ai_appropriate → checks if input is polite/respectful
• ai_professional → checks if input is written professionally
• ai_topic:laravel → checks if input is about a topic
• ai_custom:"instruction" → custom instruction for AI

---

Example

$data = ['feedback' => 'This product is trash!!!'];

$rules = [
    'feedback' => 'required|ai_appropriate',
];

$validator = Validator::make($data, $rules);

if ($validator->fails()) {
    dd($validator->errors()); 
}

✅ Output example:

[
    "feedback" => [
        "The feedback failed AI appropriate validation."
    ]
]

---

Roadmap

• Add multilingual validation prompts
• Support for streaming AI responses
• Configurable strictness levels (lenient, medium, strict)
• Fallback AI driver (e.g., use Gemini if OpenAI quota exceeded)
