AutoLingo — Automatic Translation for Polylang
Settings page — choose your translation provider (DeepL, OpenAI, Google), API key, source and target languages, and which modules to enable.
AutoLingo is the automatic translation plugin for Polylang. It auto-translates your posts and pages using DeepL, OpenAI (ChatGPT) or Google Translate — created and synced natively with Polylang. AutoLingo Pro adds WooCommerce products, SEO metadata (Yoast, RankMath), ACF fields and page builder support (Elementor, Beaver Builder, Bricks).
Whether you need Polylang automatic translation for a single post or your entire content library, AutoLingo does it on publish, in bulk, or via WP-CLI, with AI translation quality from DeepL, OpenAI or Google.

External Services
This plugin optionally connects to one of three 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.
