Openrouter for Multilang app

Supports both UI 1.3 and 2.0 interfaces

The Openrouter plugin works in both backend interfaces of the Multilang application and supports both the light and dark backend themes for UI 2.0.

The Openrouter plugin for the Multilang app: smart AI-powered content translation in Webasyst, featuring a glossary, a custom prompt, and user-friendly settings.

OpenRouter - AI translator for an online store on Webasyst.

The OpenRouter plugin connects to the Multilang application and enables automatic translation of products, categories, and store content using neural networks. Instead of being tied to a single provider, you get access to hundreds of LLM models from OpenAI, Anthropic, Google, Meta, and other developers through a single OpenRouter API key. One plugin handles the localization of your online store into any language in the world.

What is the plugin for?

Manually translating a catalog into several languages takes days of work and requires language expertise. OpenRouter takes care of this routine: select a language, and the neural network will translate product names, descriptions, and characteristics while preserving the HTML structure and terminology of your business. A multilingual store opens up foreign markets, increases organic traffic from search engines, and improves conversion rates thanks to content that is clear and understandable to customers.

Key features of the OpenRouter plugin.

Access to hundreds of models with a single key.

OpenRouter is a single gateway to language models. You only need one API key to switch between cost-effective and top-tier models by simply changing the model slug in the settings. It is suitable both for testing with free models and for production-scale workloads with paid models.

Terminology dictionary.

Add your own translation variants for brands, SKUs, and specialized terms - the plugin will reliably insert them into the result. Product names and trademarks will remain unchanged.

Preserving markup and translation cache.

HTML tags and special characters are protected by service tokens and are not damaged during translation. Completed translations are cached: restarting the process does not consume additional tokens and is performed instantly.

Smart limit management.

The built-in request rate limiter (RPM) and automatic retry with a waiting period when API limits are reached eliminate errors such as "too many requests". Progress is displayed directly on the page, and the "Stop" button allows you to stop translation generation at any time.

Custom prompt and fine-tuning.

You can supplement the translator's system instruction for your specific niche, as well as enable the option to replace em dashes, which are commonly generated by AI.

Tip: use paid models for batch catalog translations - their cost is only a few cents even for thousands of items. Free models are convenient for getting started, but they have daily request limits.

Who is this plugin for?

The plugin is designed for owners of Webasyst Shop-Script stores and web studios that are developing international sales or managing multilingual websites. It is also useful for marketers scaling traffic from new regions and content managers who need to quickly localize thousands of product pages without hiring translators.

How to use it.

1. Install the plugin and obtain an API key in your OpenRouter account.
2. In the plugin settings, enter the key and specify the model slug from the OpenRouter model catalog page.
3. Select OpenRouter as the translation provider in the Multilang application settings or directly in the editor.
4. Start translating products, categories, or pages - progress is displayed on the screen, and the result is immediately added to the multilingual content fields.

Benefits of using the OpenRouter plugin.

• Freedom of model choice - no dependency on a single vendor: change one line in the settings and compare the translation quality of different neural networks.
• Budget savings - competitive model pricing through the aggregator and caching that prevents tokens from being charged again.
• Stability - automatic request retries and limit control are designed for large catalogs.
• Unified billing - all models, projects, and spending statistics in a single OpenRouter account.
• Simple integration - native integration with the Multilang application without code modifications; current PHP versions are supported.
