Powered by the OpenRouter API, it translates your content fields to a variety of target languages within seconds. Key features include: * **Gutenberg & Classic Editors**: Complete sidebar integration in Gutenberg and a custom metabox inside the Classic Editor. * **Granular Field Selection**: Translate the Title, Content, Excerpt, or any arbitrary custom fields simultaneously. * **Custom Field Mapping**: Define translatable fields dynamically using custom CSS selectors to target specific page elements. * **Performance Caching**: Local caching via the WordPress Transients API preserves translations for 24 hours to speed up repeated edits and minimize API usage. * **System Prompt Customization**: Customize the core instructions sent to translation models, with full support for HTML tag preservation and specific typography rules. * **Dynamic Model Selection**: Connect to any model on OpenRouter, with visual badges highlighting free tiers, fast options, and auto-routing models. * **Tabbed Settings Dashboard**: A fully responsive settings page with slide-in tab transitions and persisted navigation states. #### External Service Integration This plugin relies on the external service **OpenRouter** (https://openrouter.ai) to perform translation requests. * **Service URL**: https://openrouter.ai * **Terms of Service**: https://openrouter.ai/terms * **Privacy Policy**: https://openrouter. ai/privacy * **Data Transmission**: When you perform a translation, the selected text, chosen target language, system prompt guidelines, and your configured API key are securely transmitted via HTTPS requests to OpenRouter’s API endpoint (https:// openrouter.ai/api/v1/chat/completions). No other personal or site details are shared. ### Help & Guide #### Step-by-Step Translation Guide 1. Open any supported Post or Page. 2. Write or paste your content in the Title, Content, Excerpt, or Custom text area. 3. Observe that the translation panel automatically detects which fields contain text and lights them up. 4. Select the field(s) you wish to translate. 5. Select your target language from the buttons group. 6. Click **Translate Now**. 7. The fields will temporarily disable during execution and then update automatically. #### System Prompt Best Practices Use the system prompt to guide your translation model. Always keep the `{target- lang}` placeholder, which is replaced dynamically. To prevent models from breaking layouts, instruct them to preserve: * WordPress blocks and shortcodes (e.g., `[ gallery]`) * HTML tags and attribute values (e.g., class names, URLs) * Typography preferences (e.g., prohibiting em dashes) ## Screenshots [[ [[ ## Installation 1. Upload the `hypermew-ai-translator` directory to the `/wp-content/plugins/` directory, or install it through the WordPress plugins administration screen. 2. Activate the plugin through the ‘Plugins’ menu in WordPress. 3. Navigate to **Settings -> HyperMew Translator** to input your OpenRouter API Key. 4. Customize your preferred translation model, target languages, and enabled post types. 5. Save the configuration and edit any supported Post or Page to access the translation module. ## FAQ ### Do I need an OpenRouter API key to use this plugin? Yes. You must sign up at openrouter.ai, generate a secret API key, and save it in the settings dashboard. ### Which models are supported? The plugin fetches all active OpenRouter models dynamically. It includes built-in defaults such as: * Llama 3 8B Instruct (Free) * Mistral 7B Instruct (Free) * Claude 3 Haiku * OpenRouter Auto (Dynamic model selection) * You can also specify any exact custom model identifier path supported by OpenRouter. ### How does the cache work? When local caching is enabled in settings, the plugin saves the successful translation output locally using WordPress Transients. If the exact same text is translated to the same language with the same model, it will be served instantly from the cache, bypassing the API to save you money. ### How do I configure custom fields? Under the “General Settings” tab in settings, click “Add Custom Field”. Specify a label (e.g., Subtitle) and its unique CSS selector in the page DOM (e.g., `#subtitle`). The translator panel will automatically detect this selector and translate its value when editing. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “HyperMew AI Translator” is open source software.
