AutoLingo — Automatic Translation for Polylang & WPML

AutoLingo translates your Polylang or WPML site automatically. Publish a post in your language and AutoLingo creates its translations in every other language, with DeepL, Google Translate, Microsoft Translator, OpenAI (ChatGPT) or DeepSeek, on your own API keys, with no markup.

The free version includes

• All five providers, with automatic fallback when a quota runs out: about 3,000,000 free characters a month with free DeepL, Google and Microsoft accounts
• Translation on publish, a Translate link in the post list and the editor, and bulk translation with WP-CLI
• Categories, tags, menus and image alt text, not just posts
• Gutenberg, the Classic Editor and shortcode builders (Divi, WPBakery, Flatsome)

AutoLingo Pro adds Elementor, Bricks and Beaver Builder, SEO meta (Yoast, RankMath, SEOPress, The SEO Framework), ACF fields and WooCommerce, plus AutoLingo AI with no API key.

Features (Free)

• Translate Gutenberg content (title, blocks, excerpt) on publish or manually
• Manual translate button in the post editor and post list
• Bulk translation via WP-CLI (translate-missing, translate-all)
• Nav menu translation (Polylang and WPML)
• Five providers: DeepL (Free and Pro, auto-detected from the :fx key suffix), Google Translate, Microsoft Translator, OpenAI and DeepSeek
• Automatic fallback: when the selected provider runs out of quota, the next one that has a key translates — free DeepL, Google and Microsoft accounts add up to about 3,000,000 characters a month
• Credit balance check before each translation
• Admin alert + dashboard widget when credit runs low
• Category and tag translation — term names (and descriptions) are genuinely translated via your chosen provider, not just linked to an existing Polylang/WPML translation
• Image alt text translation — when a translated media item exists, its alt text is translated too, not just copied
• Image alt and title text inside your content (Gutenberg images, HTML) translated in the same call as the rest
• Context-aware: the provider is told what it translates (blog post, page, product, category, menu item) for better short texts
• Post meta copy on creation (theme settings, page templates, layout options)
• Shortcode-based builders (Divi, WPBakery, Flatsome) — shortcodes preserved verbatim

Features (Pro)

AutoLingo Pro adds:

• Page builder support: Elementor, Beaver Builder, Bricks Builder

• Bricks Builder — _bricks_page_content_2 (JSON), nested items (accordion, tabs)

Shortcode-based builders (Divi, WPBakery, Flatsome) are supported on the free plan — their shortcodes are preserved verbatim during translation.

SEO plugin support (Pro)

• Yoast SEO — title, meta description, focus keyword

Reliability

• Exponential back-off retry on HTTP 429 (rate limit): 2 s → 4 s → 8 s, up to 3 retries
• Dual lock (static + transient) prevents duplicate translations on Gutenberg REST saves
• Translation log viewer in the admin (DB-backed, 30-day retention)
• Integration test suite — 41 tests covering all modules

External Services

This plugin optionally connects to one of four external translation APIs depending on which provider you choose in Settings → AutoLingo. No data is ever sent without an explicit translation action and a valid API key that you supply yourself.

DeepL

What it is: DeepL is a machine translation service. This plugin uses the DeepL REST API to translate your post content.

What data is sent: The text content of your posts (title, body, excerpt) is sent to DeepL’s servers for translation. If you use the Glossary feature, your glossary terms (source and target words) are also sent to create a DeepL glossary. No personally identifiable information about your site visitors is transmitted.

When it is sent: Only when a translation is triggered — either manually via the Translate button, automatically on publish (if enabled in settings), via WP-CLI, or when syncing a glossary.

Service endpoint: api.deepl.com (Pro) or api-free.deepl.com (Free plan)

OpenAI

What it is: OpenAI provides the GPT language model API. This plugin uses the gpt-4o-mini model to translate your post content when OpenAI is selected as the provider.

What data is sent: The text content of your posts is sent to OpenAI’s servers. No visitor data is transmitted.

When it is sent: Only when a translation is triggered manually or on publish.

Microsoft Translator

What it is: Microsoft Translator (Azure AI Translator, Text API v3) provides machine translation. This plugin uses it to translate post content when Microsoft Translator is selected as the provider, or when it takes over because the selected provider’s quota is used up.

When it is sent: Only when a translation is triggered manually or on publish, and only if you entered a Microsoft Translator key.
