Stop paying €300/month for translations that aren’t even yours!
Most WordPress translation plugins charge monthly based on word count — and when you cancel, your translations disappear. WP AI API Translate Multilang works differently. You use your own AI API key from Anthropic Claude, OpenAI ChatGPT or Google Gemini, and the plugin translates your content directly. Your translations are stored in your own WordPress database. Cancel whenever you want — your translations stay put.
How does it work?
Install the plugin, enter your API key, select your target languages and click translate. The plugin sends your content to the AI provider of your choice, receives the translation and saves it as a WordPress post in your own database. No external servers, no cloud dependency, no word limits.
Translating an average 500-word page costs roughly €0.005 to €0.02 — depending on which AI model you choose. That’s about €5 to translate a complete 500-page website. Compare that to WeGlot’s €150–€699/month.
Three AI providers, one plugin
Choose the provider and model that suits you:
- Anthropic Claude (Sonnet 4.5, Haiku 4.5) — nuanced translations with excellent tone preservation
- OpenAI GPT (GPT-4o, GPT-4o Mini, GPT-4.1 Nano) — fast and reliable, with ultra-cheap options from €0.01 per page
- Google Gemini (2.5 Pro, 2.0 Flash, 2.0 Flash-Lite) — powerful and extremely affordable
Switch providers anytime. Your translations are independent of the AI provider used.
Built for SEO
Every translated page gets its own clean URL with language prefix (/en/, /es/, /de/). The plugin automatically generates hreflang tags, sets canonical URLs, translates meta titles and descriptions, and works alongside Yoast SEO and RankMath. Your translated pages get fully indexed by Google and other search engines.
Glossary for brand consistency
Define how specific terms should always be translated. Technical terms, brand names, product names — add them to the glossary and the plugin ensures they’re translated consistently on every page, every time.
