README

A Filament 4 & 5 plugin that provides translatable form fields and infolist entries with AI-powered translation generation via laravel/ai. Designed to work with spatie/laravel-translatable.

Features

TranslatableInput — A form field with two display modes: modal (default) or inline
TranslatableEntry — An infolist entry with two display modes: inline (expandable) or modal
AI Translation — Generate all translations in a single API call using structured output
Configurable — Set languages, source locale, AI provider/model globally or per-panel
Disable AI — Optionally disable the AI section while keeping manual translation editing

Requirements

PHP ^8.3
Laravel ^12.0 | ^13.0
Filament ^4.0 | ^5.0

Installation

composer require backtik-ch/filament-translatable

Publish the config file:

php artisan vendor:publish --tag="filament-translatable-config"

Configuration

// config/filament-translatable.php

return [
    'languages' => ['fr', 'de', 'it', 'en'],
    'source_locale' => 'fr',
    'ai' => [
        'enabled' => env('FILAMENT_TRANSLATABLE_AI_ENABLED', true),
        'provider' => env('FILAMENT_TRANSLATABLE_AI_PROVIDER', 'anthropic'),
        'model' => env('FILAMENT_TRANSLATABLE_AI_MODEL', 'claude-haiku-4-5-20251001'),
        'prompt' => 'Translate the following text from :source_language to :target_language. Return only the translation, nothing else.',
    ],
];

API Keys

API keys are managed by laravel/ai. Add the relevant key to your .env:

# Anthropic
ANTHROPIC_API_KEY=sk-ant-...

# OpenAI
OPENAI_API_KEY=sk-...

# Disable AI (keep manual editing only)
FILAMENT_TRANSLATABLE_AI_ENABLED=false

See the laravel/ai documentation for all supported providers.

Panel Plugin Setup

use Backtik\FilamentTranslatable\FilamentTranslatablePlugin;

public function panel(Panel $panel): Panel
{
    return $panel
        ->plugin(
            FilamentTranslatablePlugin::make()
                ->languages(['fr', 'de', 'en'])
                ->sourceLocale('fr')
                ->aiProvider('openai')
                ->aiModel('gpt-4o-mini')
        );
}

All plugin methods are optional — values fall back to the config file.

Usage

Model Setup

Your model must use spatie/laravel-translatable and the translatable columns must be json in the database:

use Spatie\Translatable\HasTranslations;

class Post extends Model
{
    use HasTranslations;

    public $translatable = ['title', 'description'];
}

Form Field

use Backtik\FilamentTranslatable\Forms\Components\TranslatableInput;

// Simple text input (short content like titles)
TranslatableInput::make('title')

// Textarea for longer content
TranslatableInput::make('description')->inputType('textarea')

// Inline mode — all locale fields rendered directly in the form
TranslatableInput::make('title')->inline()

// Inline textarea
TranslatableInput::make('description')->inline()->inputType('textarea')

Modal mode (default)

The field displays the source locale value as a readonly preview. Clicking the translate button opens a modal where you can:

Edit translations for each configured language
Select a source language
Click "Generate translations" to auto-translate all languages in one AI call

Inline mode

All locale fields are rendered directly in the form without requiring a modal. The AI generation section is also displayed inline. Best suited for forms where you want all translations visible at a glance.

Infolist Entry

use Backtik\FilamentTranslatable\Infolists\Components\TranslatableEntry;

// Inline mode (default) — shows all translations with expand/collapse
TranslatableEntry::make('title')

// Modal mode — shows source text, click to view all translations in a modal
TranslatableEntry::make('description')->modal()

// Truncate text to a specific number of lines
TranslatableEntry::make('description')->lineClamp(3)
TranslatableEntry::make('description')->modal()->lineClamp(2)

Inline mode (default)

Displays the first language inline with an expandable section to reveal the remaining translations.

Modal mode

Displays the source locale text directly. A "View translations" link opens a Filament modal showing all translations. Best for longer text content.
