LATW Multilingual

Give every visitor your website in their own language, for free. LATW Multilingual is a free WordPress plugin that adds unlimited languages, a clean switcher and native /en/ URLs, with the full SEO stack built in: hreflang, canonical tags and sitemaps. Instead of cloning every post per language, it keeps one original post and layers translations on top, so your database stays clean and your 100 PageSpeed score survives. Optional Pro adds AI translation using your own OpenAI key.

If you ever want to automate the work, there is an optional Pro version with AI translation, but it runs on a bring your own key model: you connect your own OpenAI key and pay the provider directly at cost, with no per word markup, and you can bulk translate an entire site in one run. The free core, though, is the heart of the project, and it stays free.
