TranslateWP Pro

Your entire website, in every language — translated by AI, owned by you.

TranslateWP Pro turns any WordPress or WooCommerce site into a true multilingual site in minutes. Connect OpenAI, Claude (Anthropic) or DeepL, pick your languages, and watch your frontend translate itself — page text, buttons, forms, tooltips, meta tags, product data, even customer emails. Every translation is stored in your own database: you pay for each string once, then serve it instantly, forever.

Premium-grade. Free. No locked features, no upsells, no per-word subscription.

Why site owners choose TranslateWP Pro

Three AI providers, one switch. Use OpenAI's full current lineup (GPT-5.5, GPT-5.4, GPT-5, GPT-4.1, GPT-4o families — 12 models), Anthropic's Claude (Haiku 4.5, Sonnet 5, Sonnet 4.6, Opus 4.8, Fable 5), or DeepL. Change providers anytime — and if your active provider ever fails or hits a limit, the others take over automatically.

Translate once, serve forever. Translations live in your database, not on someone else's cloud. No monthly per-pageview fees, no vendor lock-in, no external service between your visitors and your content. Translating 100,000 characters costs roughly $0.02 on GPT-4o Mini or $0.16 on Claude Haiku 4.5 — once.

Everything on the page, not just the paragraphs. TranslateWP Pro captures what other plugins miss: button labels, form placeholders, image alt text, tooltips, ARIA labels, validation messages, SEO and social meta tags — and it keeps translating content that arrives after the page loads, like mini-carts, "load more" results and product filters.

Spending caps you actually control. Monthly and daily character limits, separate USD budgets for OpenAI and Claude, a global daily cap for visitor-triggered translation, and an email alert at 80% of budget. Runaway API bills are structurally impossible.

FAQ

Is it really free? Yes — the full plugin, every feature. You only pay your chosen AI provider for the translations themselves, at their standard API rates, under the spending caps you set.

Do I need coding skills? No. Paste an API key, tick your languages, enable auto-translate. The included guide walks through everything step by step.

What happens to my translations if I switch providers? Nothing — they're yours, stored in your WordPress database, and keep working regardless of which provider translates new strings.

Will it slow my site down? No. Pages render from stored translations with async translation happening in the background, and the optional page cache makes translated pages faster than most untranslated ones.
