Every feature serves one promise: translations you can trust.
Other tools stop at "translated." LingoTuner is built around what happens next - verifying, controlling, and protecting your content in every language.
Self-verifying AI translation
LingoTuner doesn't just translate - it proves the translation. Your text is translated, then back-translated into your own language, then compared against the original. Discrepancies get caught and corrected before publication.
Run the loop two ways:
⚡ Autopilot
The AI Agent runs the entire loop by itself: translate, back-translate, compare, fix - and then reports back. After every run you get a summary of exactly what it modified and why, so the quality check is never a black box. Ideal for product catalogs, documents, and continuous updates.
🎯 Hands-on
You review the back-translation personally, refine the reference text, and re-verify until every nuance lands. No knowledge of the target language required. Ideal for labels, contracts, and brand-critical copy.
And the loop is engine-agnostic: run it with our AI Agent, or with the machine translation engine you already trust - Google Translate, Microsoft Translator, DeepL, and more. LingoTuner adds verification on top; it never forces you to switch.
Most tools make you choose between speed and certainty. The loop gives you both - with any engine you choose.
Stay in control
Machine translation fails on ambiguity. These features put you back in charge of meaning.
Word-sense control
"Nail" the hardware or "nail" the fingernail? Choose the correct meaning for ambiguous terms once, and LingoTuner applies it consistently across your entire website or document. The #1 source of embarrassing machine-translation errors - eliminated.
Protected terms
Brand names, model numbers, SKUs, and signature marketing lines stay exactly as you wrote them - untranslated, in every language. Your brand never gets "translated" into something it isn't.
Your engine, your choice
Use LingoTuner's AI Agent, or plug in the engine you already rely on - Google Translate, Microsoft Translator, DeepL, and others. Compare results, pick the best output per project, and never get locked into a single provider. The verification loop works the same on top of all of them.
Reference text editing
Sometimes the best fix isn't in the translation - it's in the source. Edit your reference text to remove ambiguity, and every language benefits at once. One edit, twenty better translations.
Built for scale
From one paragraph to an entire catalog - without the process changing.
Unlimited languages, all at once
Once your reference text is verified, translate it into every language you need in a single run - there's no language cap and no per-language fee, on any plan. Verifying once and publishing in twenty languages is the whole point.
Format preservation
Upload a .docx, get a .docx back - same layout, same styles, same structure. Your translated manual looks like your original manual, not like a text dump.
Webstore integrations
Native plugins for Shopify, WooCommerce, Magento, and OpenCart. Translate and verify products, categories, SEO titles, metas, and slugs directly from your store - and keep them verified as your catalog grows.
API access
Build the loop into your own workflow. Everything LingoTuner does in the app, your systems can do automatically through the API.
Pay for what you use
Quality shouldn't require an agency budget.
A fraction of agency cost
Verified translations from €0.000029 per character - orders of magnitude below professional translation rates, with quality you can check yourself.
Characters that don't expire
On annual plans, unused characters roll over. Buy once, use them when your content is ready - no "use it or lose it."
Subscription or single project
Monthly plans, annual plans with 17% savings, or a one-off project with no subscription at all. Start free with 200,000 characters of translated output - about 33,000 words, in as many languages as you like.
