LATW AI Translation for WPML
LATW AI Translation vs the WPML AI Translation Chrome Extension: plugin or browser tool?
The open-source Chrome extension adds AI-translate buttons directly to WPML's Advanced Translation Editor - free, but tied to an open browser tab: close it or lose your connection mid-run and the job stops, wasting the tokens already spent. LATW delegates every request to OpenAI as a background job on your server instead, which makes it both safer (nothing is lost if something breaks) and faster (not limited to one tab firing requests one at a time).

The real difference: a background job vs a browser tab
Both tools ultimately fill in the same WPML translation segments with AI output. What differs is where that work actually happens - and that one difference makes LATW both safer and faster for anything beyond a handful of strings.
A helper that only works while you're watching it
The extension adds buttons to translate one segment at a time, or sequentially in bulk, directly inside the ATE page. It preserves brand names and HTML structure via a system prompt, but the whole process runs client-side in your browser: it needs that tab open and connected the entire time, and it can only fire one request at a time, so a large batch is both slower and riskier - close the tab or lose your connection partway through, and the run stops with the already-spent tokens wasted.
Submit it, then walk away - safer and faster
Select content in WordPress and submit it for translation - each request is delegated to OpenAI as a background job on your server, not from your browser. That makes it safer: close the tab, lose your connection, even have the site hiccup mid-run, and nothing is wasted - it simply resumes and asks OpenAI for what's still pending. It's also faster on anything beyond a few strings, since requests aren't limited to one browser tab firing them one at a time.
Where LATW pulls ahead of the Chrome extension
Safer: nothing is lost if something breaks
The extension runs client-side, so closing the tab, losing your connection or a laptop going to sleep partway through a large batch stops the job and wastes the tokens already spent. LATW delegates every request to OpenAI as a background job on your server - if your site itself hiccups mid-run, it just resumes and re-queries OpenAI for what's still pending.
Faster on anything beyond a few strings
The extension fires one request at a time from a single browser tab, so bulk jobs run sequentially. LATW's background requests aren't limited to one open tab, so larger translation batches complete faster.
No browser tab required
Submit a translation job from WordPress and close your browser - it keeps running server-side. The Chrome extension stops the moment its tab closes.
A glossary and website context
Define preferred terms and describe your site's tone once, and every translation uses them. The extension has no persistent glossary or context field - only a per-session system prompt.
Full translation history
Every translation is logged with the model used, the prompt sent and the response received. The extension keeps no equivalent record once a tab is closed.
Theme and plugin string translation
LATW also covers WPML's String Translation module for menus, buttons and theme/plugin text. The extension is scoped to the Advanced Translation Editor screen only.
Maintained with paid support
LATW is a commercial product with ongoing updates and support. The Chrome extension is a community open-source project with no guaranteed maintenance or support channel.
Where the Chrome extension is still the safer pick
-
Genuinely free, forever: fully open source with no license fee at all - the only cost is your own AI provider usage.
-
Multi-provider flexibility via OpenRouter: access to Claude, Gemini, Llama and dozens of other models through one API key, not locked to a single provider.
-
No extra plugin on your WordPress site: everything runs in the browser, so it adds no PHP code, database tables or admin screens to your live site.
-
Open source and inspectable: the full source is on GitHub, so you can audit exactly what it sends and how before trusting it with your API key.

Is the WPML AI Translation Chrome Extension a replacement for a WordPress plugin?+
Not exactly. It's a browser extension that adds AI-translate buttons directly to WPML's Advanced Translation Editor page - it doesn't install anything on your WordPress site itself, and only works while you're on that screen in Chrome.
Is the Chrome extension really free?+
Yes, the extension itself is free and open source under a GPL-2.0 license. You still pay OpenAI or OpenRouter directly for the AI usage, the same BYOK model LATW uses, just without any plugin license fee at all.
Do I need to keep my browser open while it translates?+
Yes. The extension runs client-side inside your Chrome tab, so bulk translation only progresses while that tab stays open on WPML's Advanced Translation Editor. LATW instead runs the job on your server, so you can close the browser and it keeps going.
What happens if my connection drops or the tab closes mid-translation?+
With the extension, the run simply stops - any tokens already spent on that batch are wasted, and you have to check which segments actually got translated before restarting. With LATW, nothing is lost: each request is a background job delegated to OpenAI from your server, so if your connection drops, your laptop sleeps, or the site itself hiccups mid-run, it just resumes and re-queries OpenAI for whatever is still pending.
Is LATW actually faster than the Chrome extension for large translation jobs?+
Yes, for anything beyond a handful of strings. The extension fires one AI request at a time from a single browser tab, so a large batch translates sequentially. LATW's background requests to OpenAI aren't tied to one tab firing them one by one, so bigger jobs complete faster.
Can the Chrome extension use models other than OpenAI?+
Yes - through OpenRouter it can reach Claude, Gemini, Llama and many other models with one API key, which is broader provider choice than LATW currently offers. LATW instead focuses exclusively on OpenAI's GPT-5 family.
Is LATW AI Translation for WPML better than the Chrome extension?+
For most production sites, yes - LATW runs in the background without needing a browser tab open, adds a glossary, website context and full translation history, and comes with maintained support. The Chrome extension's strengths are being completely free and giving you a wider choice of AI models via OpenRouter.
Can I use both together?+
There's little reason to. Both add AI translation on top of the same WPML Advanced Translation Editor content, so most sites pick one - LATW for unattended background translation with more built-in controls, or the extension for a free, manual, provider-flexible workflow.
Submit it once, close the tab
Background translation, glossary, website context and full history - no browser tab to babysit.
