Why OpenAI
Stop paying agencies for copy GPT-4o handles better
OpenAI's GPT-4o consistently tops independent translation benchmarks for marketing and editorial output — and runs at a tiny fraction of agency cost. With AutoPoly, it slots directly into Polylang so every post, page, and product description gets the same flagship-grade quality.
Editorial-grade output
GPT-4o handles idiom, nuance, and brand voice better than any other AI provider — translations don't read as machine-translated.

★★★★★
I had an issue with some configurations during setup, but the support team helped resolve it immediately.
★★★★★
This plugin is doing a better job for me with translation than other AI plugins I tried before on my website. I just plug it with Gemini Pro and I've paid less than $1 for massive translates on my website with the 2.5 Flash model.
OpenAI charges roughly $0.10–0.30 per 1,000 words translated, depending on which GPT model you choose. For a typical small WordPress site (50–100 pages), that's usually under $5 in one-time API costs. There are no per-translation fees from us — you only pay OpenAI directly for what you use.
Yes — translation requires a paid OpenAI API account, which is separate from a ChatGPT subscription. Most users top up $5–10 of credit and that covers hundreds of pages. Sign up and add credit at platform.openai.com.
We support GPT-4o, GPT-4 Turbo, GPT-4, and GPT-3.5 Turbo. We recommend GPT-4o for the best balance of quality and cost — it's the latest flagship model and produces the most accurate translations across all languages.
Your API key is stored encrypted in your WordPress database and is only used server-side. Translation requests go directly from your WordPress site to OpenAI — we never proxy or store any of your content or your API key.
Yes. The plugin supports OpenAI, Gemini, Claude, DeepL, Google Translate, and Yandex (depending on which plugin you're using). You can switch the active provider any time from the plugin settings — already-translated content stays as-is.
Yes — our plugin sends WooCommerce product data, ACF custom fields, and Yoast/RankMath SEO meta through OpenAI for translation, then writes the translated values back to the right WordPress fields. HTML and shortcodes are preserved automatically.
