Your Bilbao machinery exporter sends quotes in Spanish to buyers in France and Germany, the city runs on three languages — Spanish, Basque and English — and machine translation keeps mangling the tech

Bilbao is a three-language business town: Spanish and Basque are official in the Basque Country, English runs through the port and the international firms (Iberdrola, the BBK group, the Guggenheim-driven tourism industry), and French and German matter for exporters selling into Europe. A machinery firm sending quotes to Lyon and Munich cannot afford machine-translation errors in specifications — but it also cannot afford a human translator for every email. The tools below cover that spectrum, from free quality to self-hosted privacy.

1. DeepL — free tier, Pro ~€8.74/mo The best translation quality for business prose in supported language pairs (Spanish, French, German, English among them). Free tier is usable; Pro adds unlimited volume, document translation and glossary features. Check DeepL's current language list before assuming your pair is covered — it does not cover every language.

2. Google Translate — free The breadth champion: 100+ languages, including Basque (Euskera), and instant document and image translation. Quality on European business languages trails DeepL slightly but is perfectly usable. The only mainstream option that covers Basque out of the box.

3. Claude / ChatGPT — free tiers, Pro ~$20/mo LLM translation is the 2026 secret weapon: you paste the whole quote, give context ('translate for a French industrial buyer, keep the technical terms, formal tone'), and get a translation that handles tone and jargon — not just words. Free tiers handle this easily for documents up to a few pages.

4. immersive-translate — open source, 18,635 stars A free browser extension that shows bilingual side-by-side translation for web pages, PDFs, EPUBs and subtitles. The best tool for reading foreign-language sites and documents without leaving your browser. Free and open source.

5. LibreTranslate — open source, 16,185 stars A self-hosted translation API you can run on your own server, offline-capable. Quality is a step below the frontier LLMs, but for sensitive export contracts or continuous internal volume, keeping the data on-prem is worth the quality trade-off.

6. Lingvanex — ~$5-10/mo On-premises translation options plus a SaaS tier. A practical middle ground when a Basque company needs translation embedded in internal tools without sending data abroad.

Quick comparison: DeepL free/Pro ~€8.74 (best quality in supported pairs); Google Translate free (broadest coverage, includes Basque); Claude/ChatGPT free tiers (context-aware whole-document translation); immersive-translate free (bilingual reading in-browser); LibreTranslate free self-hosted (on-prem privacy); Lingvanex ~$5-10/mo (embedded/on-prem options).

The workflow that works for exporters: LLM (Claude or ChatGPT) for the first full draft of the quote — context matters more than word-for-word accuracy; DeepL or a native reviewer for the final pass; immersive-translate for reading your buyers' sites. And the Basque note: Google Translate covers Euskera; for Basque-language business documents, treat machine output as a draft and have a native speaker review — the language's agglutinative grammar trips up machine translation more than Spanish or French.

❓ FAQ

Is DeepL really better than Google Translate?

For business prose in supported language pairs, usually yes — more natural phrasing. Google wins on breadth (100+ languages including Basque) and on free document/image translation. Test your specific pair.

Can an LLM translate a whole PDF document?

Yes — Claude, ChatGPT and Gemini read PDFs directly. Formatting can break (tables, columns), so for layout-critical documents convert to text or Markdown first, then translate.

Which tool handles Basque (Euskera)?

Google Translate is the mainstream option that covers Basque. DeepL does not list Basque in its standard language set — check the current list. Treat Basque machine output as a draft; native review is essential.

Is self-hosted LibreTranslate good enough for business?

For standard text at volume, yes — and the data stays on-prem. For nuanced, high-stakes documents, frontier LLMs or DeepL plus human review remain the better choice.
