Guide: AI in business › AI in marketing, advertising and content
An AI translator for business is a tool based on a language model that translates emails and offers, documents and even conversations faster and more naturally than older machine translators, but it still needs a human for texts for which the company bears legal or reputational responsibility. The choice is not decided by which model “translates best”. It is decided by where your data goes and who checks the result. Below we compare tools and prices, propose a rollout plan and show the limits you are better off not crossing.
In 60 seconds AI translators in five sentences
- What it can do: translates text, files or speech with the help of AI and can preserve the company’s tone and terminology.
- Who will find it useful: exporting companies, customer service for foreign clients and teams that write in several languages every day.
- Prices: from free versions to business plans, and DeepL Pro starts at 7.49 euros per user per month with annual billing.
- First step: a glossary of company terms and one rule stating what may be pasted into the tool.
- Limit: contracts, medical texts and crisis statements are always checked by a person who knows the language.
How does an AI translator differ from an old-style machine translator?
Classic machine translation worked sentence by sentence. An AI translator based on a large language model (a program that has learnt from billions of sentences and predicts the most sensible continuation of a text) looks at the whole paragraph, and often the whole document, so it understands context better and knows that an “offer” in a sales email is something different from an “offer” in a job advert.
The second difference is that you can talk to an AI-based translator. Write “translate into German, formal register, for a purchasing director, no anglicisms” and you will get text in that style. The old translators couldn’t do that. We show how to phrase such instructions so that they work every time in our guide to prompts for marketing, and in English tools of this kind are simply called “AI translators”.
The third difference can be a problem. AI can be overconfident, and when it doesn’t understand a passage, it doesn’t leave a gap but adds something that sounds good. So for important texts, always compare the output with the original. We explain where such fabrications come from in our piece on AI hallucinations, and for the wider context, meaning where translation sits among other uses of AI in business, see our guide to AI for marketing and PR.
Who saves the most time with an AI translator?
The biggest winners are companies where translation is everyday routine rather than a one-off project. A sales rep replies to an enquiry from Germany. Customer service receives a complaint in Czech. Marketing prepares an English version of a product page, and each of these people currently loses time copying text between windows or waiting until a translator has a moment.
- Sales correspondence and customer service: a quick reply in the customer’s language that keeps the company’s tone.
- Offers, product sheets and manuals: translating entire files without breaking the formatting.
- Internal communications in companies with teams abroad: announcements, procedures, training.
- Meetings and calls: live speech translation, for now with the caveats described below.
- Monitoring foreign media and competitors: understanding the gist of a text before deciding whether to commission a full translation.
DeepL, Google Translate, ChatGPT or Copilot?
The question “best LLM for translation” (i.e. which language model translates best) has no single answer, because quality changes with every model version and depends on the language pair. In a business, other things matter more. Does the tool stick to a term glossary? Does it translate files without breaking the layout? And what happens to the data?
Tłumacz ChatGPT (w wyszukiwarce ludzie wpisują też „translator ChatGPT”) sprawdza się najlepiej tam, gdzie tekst trzeba przy okazji przeredagować, czyli skrócić, zmienić ton albo dopasować do odbiorcy; to w gruncie rzeczy praca redakcyjna, którą opisujemy przy AI copywriting. Copilot as a translator is convenient for companies working in Microsoft 365, because it runs directly in Word and Outlook. DeepL was built for translation and has features chatbots lack: glossaries (term lists enforced in every translation) and translation memory.
| Tool | Best for | Strength | What to watch out for |
|---|---|---|---|
| DeepL Pro | documents and consistent terminology | glossaries, file translation, Pro customer data is not used to train models | less freedom when editing text |
| Google Translate with Gemini | quickly understanding text and conversations when travelling | live speech translation in the app | the free version is no place for confidential documents |
| ChatGPT (translator and editor) | translations with tone adaptation and summarising | translation and editing at the same time | can “improve” the content beyond the original |
| Copilot in Microsoft 365 | companies working in Word and Outlook | translation within the document, no copying | live translation in Teams does not currently support Polish |
| Human translator + AI | contracts, regulated texts, campaigns | accountability and market knowledge | higher cost and longer turnaround |
Live conversation translation: what already works and what doesn’t yet
On 9 June 2026 Google announced Gemini 3.5 Live Translate, a speech-to-speech translation model which, according to the company, recognises more than 70 languages. It is coming to the Google Translate app on Android and iOS, and in Google Meet it is currently in a closed testing programme for selected companies.
Hasło „Copilot tłumacz” dotyczy nie tylko Worda, ale też spotkań: Microsoft ma w Teams agenta tłumacza (Interpreter), który na żywo tłumaczy wypowiedzi uczestników spotkania. Według strony pomocy Microsoft licencja Copilot daje 20 godzin tłumaczenia na osobę miesięcznie. Obsługiwanych jest dziesięć języków, między innymi angielski i niemiecki, a także francuski oraz hiszpański. Polskiego na tej liście nie ma. W praktyce rozmowa z partnerem z Niemiec, w której Polak mówi po polsku, jeszcze przez ten mechanizm nie przejdzie.

How to introduce an AI translator in your company step by step
A rollout is not about buying licences. It is about agreeing who uses what, for which texts and who checks the result, and the sequence below protects you from chaos in which every employee uses a different free tool.
- STEP 01List what the company translates
For two weeks, record the type of text and language, the volume and the name of the person translating. It often turns out that most of the volume comes from a handful of recurring text types. Start with those.
- STEP 02Divide texts into three risk groups
Define a low group (internal emails, background research), a medium group (offers, website) and a high group (contracts, safety instructions, public statements), and set a different procedure for each.
- STEP 03Build a glossary of terms
Enter product and job titles and the phrases the company does not translate, then upload it as a glossary in DeepL or as a standing instruction in ChatGPT or Copilot.
- STEP 04Choose one company tool
Choose a plan that does not train models on your data and has an admin panel, because only then will you know who is using what. Block private accounts for company business, or at least clearly discourage them.
- STEP 05Decide who checks medium- and high-risk texts
It can be someone who knows the language or an external translator, as long as every published text records that person’s name, so that it is clear whom to contact if questions arise.
- STEP 06After a month, measure the time and the number of corrections
Count how many texts went through unchanged, how many needed correcting and where the AI went wrong most often, because that is what you will use to improve the glossary.
What can you hand over to AI, and what must a human check?
The line does not run between “important” and “unimportant” text. It runs between text in which an error is easy to spot and fix, and text in which an error has consequences. AI as a translator handles meaning well, but legal and cultural nuance less well.
| Type of text | AI translator alone | Who checks |
|---|---|---|
| Internal correspondence, research | yes | nobody, or the sender spot-checks |
| Email to a customer, reply to a complaint | yes, with checks | the sender reads it before sending |
| Website, product sheet, proposal | draft | someone who knows the language and the market |
| Press release, campaign | draft | a native speaker with communications experience |
| Contract, terms and conditions, safety instructions | not as the final version | a specialist or sworn translator, a lawyer |
How much does an AI translator cost and what drives the budget?
AI translation tools are cheap compared with the cost of an error, because the time spent on corrections costs more, and for public texts so does the work of someone who knows the market and will catch sentences that sound foreign. The table shows public prices (as at 24 September 2026; ChatGPT and Microsoft excluding VAT, DeepL including VAT as shown on its website).
| Item | Cost | What it depends on |
|---|---|---|
| DeepL Pro, individual plan | €7.49 per user per month (annual) | 300,000 characters per month, 3 files, 1 glossary |
| DeepL Pro, Team plan | €24.99 per user per month (annual) | 1 million characters per user, 20 files, 5 glossaries, administration |
| DeepL Pro, Business plan | €49.99 per user per month (annual) | unlimited characters, translation memory |
| ChatGPT Business | USD 20 per user (annual) or USD 25 (monthly), min. 2 users | translation and editing in one, no training on company data by default |
| Microsoft 365 Copilot | from USD 21 (Business) to USD 30 (enterprise) per user per month | translation in Word and Outlook, interpreter in Teams |
| Human review | translator’s rate or employee time | type of text, language, deadline, legal liability |

Data security: what to paste in and what not to
The biggest risk is not translation quality but where the text ends up. An employee who pastes a customer contract into a free browser translator does not know how long that text will be stored or what it may be used for. DeepL states that Pro subscribers’ data is not used to train models and is deleted once the service has been performed, and OpenAI states that ChatGPT Business does not train on company data by default. Free accounts can be a different story.
The second layer is regulation. Since 2 February 2025, Article 4 of the AI Act has required companies using AI to ensure their staff have the relevant skills, and a short instruction on “what we don’t paste into the translator” is the cheapest way to meet this obligation. We write more about the risks in our article on the risks and ethics of AI in business, and the principles of talking to customers are covered in our piece on communication with customers.
When an AI translator pays off, and when it isn’t enough
An AI translator almost always pays off for large volumes of short, repetitive texts. As the only link in the chain for texts that build the company’s reputation abroad, it won’t do. It is time to get translation in order when employees use several different free tools, foreign customers ask what your emails mean, or product names sound different in each language every time.
Przy wejściu na nowy rynek tłumaczenie to dopiero początek, o czym piszemy szerzej w poradniku o wprowadzeniu produktu na rynek zagraniczny. Liczy się też, co o firmie piszą lokalne media i co odpowiadają o niej wyszukiwarki oraz modele AI w danym języku. Różnicę między pozycjonowaniem w Google a widocznością w odpowiedziach AI wyjaśniamy w artykule o tym, how SEO differs from GEO and AEO, and the role of the media in what ChatGPT says about a company in our piece on PR AI.
Jeśli tłumaczenia mają wesprzeć wejście na konkretny rynek, a nie tylko szybsze odpowiadanie na maile, umów rozmowę o międzynarodowym PR. Zaczynamy od jednego kraju i od tego, co tam dziś o Twojej firmie piszą media.
Lista kontrolna, próg decyzji i przykład na 90 dni
AI tłumaczenie w firmie działa dobrze, gdy zasady są spisane, zanim pracownicy wyrobią sobie własne nawyki. Poniższa lista kontrolna mieści się na jednej stronie i nadaje się do powieszenia przy biurku działu sprzedaży.
Próg decyzji ustal na starcie. Przykład: po miesiącu pracy z firmowym narzędziem czas przygotowania odpowiedzi dla klienta zagranicznego wyraźnie spadł, a liczba poprawek w tekstach publicznych nie wzrosła. Wtedy rozszerzasz licencje na kolejne działy. Jeśli poprawek przybyło, uzupełniasz słownik terminów i instrukcję, zanim dokupisz miejsca. ChatGPT tłumaczenie robi szybko, ale szybkość bez słownika oznacza trzy wersje nazwy tego samego produktu.
Dostawcy narzędzia zadaj pięć pytań. Czy dane z naszego planu trenują model? Jak długo przechowujecie przetłumaczone pliki? Czy możemy narzucić własny słownik terminów? Czy tłumaczenie plików zachowuje układ dokumentu? Kto w firmie widzi, jakie teksty i kiedy trafiły do narzędzia? Odpowiedzi zapisz w dokumentacji, bo przydadzą się przy kontroli zgodności z AI Act. Jeśli chcesz dopiero wybrać narzędzie, porównanie szerszej grupy programów znajdziesz w tekście o najlepszych narzędziach AI dla firm.
- Wiesz, jakie teksty firma tłumaczy i w jakich językach.
- Teksty są podzielone na trzy grupy ryzyka, a każda ma przypisaną osobę sprawdzającą.
- Istnieje słownik terminów: nazwy produktów, usług i stanowisk w każdym języku.
- Wszyscy używają jednego firmowego narzędzia, a nie prywatnych kont.
- Spisane jest, czego nie wklejamy do tłumacza: umowy, dane osobowe, dane finansowe klientów.
- Mierzysz czas przygotowania tekstu i liczbę poprawek przed wdrożeniem i po nim.
AI translation in a company’s international strategy
Firmy, które dobrze korzystają z tłumaczy AI, traktują je jako część większego systemu. Mają słownik terminów, jedną osobę odpowiedzialną za ton w każdym języku i lokalnego partnera, który zna media i zwyczaje. Ton marki najłatwiej przekazać tłumaczowi, ludzkiemu czy maszynowemu, gdy jest spisany w brand booku. Maszyna przyspiesza pracę. Nie wyjaśni jednak, czego oczekuje kupiec w Niemczech, a czego w Czechach.
Jeśli rozwijasz sprzedaż za granicą, zacznij od sprawdzenia, jak firma jest dziś widoczna w danym kraju: w mediach, w wyszukiwarce i w odpowiedziach AI. Jeśli chcesz to zrobić z partnerem, umów rozmowę o międzynarodowym PR; pierwszym krokiem jest przegląd widoczności firmy na jednym wybranym rynku. Powtarzalne tłumaczenia da się też spiąć z innymi procesami, co pokazujemy na przykładzie automation with AI and n8n. Gdy tłumaczy kilkanaście osób, przyda się też porządek w dostępie: w Commwork®AI system zapytania do modeli idą przez jedną firmową bramę, z kluczami po stronie serwera i dziennikiem, więc wiadomo, jaki tekst i kiedy trafił do maszyny.
The AI translation mistakes that cost companies the most
You lose control over data and naming consistency. In a single week a customer gets three different names for the same product.
One awkward phrase on a website or in a press release stays online for years. It undermines the company’s credibility in a new market.
AI translates proper names and industry terms differently every time, and correcting the same errors eats up hours every month.
A one-word difference in a liability clause can cost more than the annual translation budget.
A feature that works brilliantly in English may not support Polish. That is currently the case with live translation in Teams.
Questions about AI translators we hear from exporting companies
Which AI translator is best for a business?
For documents and fixed terminology, usually DeepL Pro, because it has glossaries and file translation. For translation combined with editing, ChatGPT or Copilot on a business plan will serve you better. The surest way to choose is to test two tools on ten real company texts.
Is ChatGPT a good translator?
Translation with ChatGPT captures meaning and tone well, especially when the model is told who the text is for. Sometimes, though, it “improves” the content beyond the original or adds details. For important texts, compare the translation with the original sentence by sentence.
Does Copilot have a translator?
Yes. Copilot in Microsoft 365 translates in Word and Outlook, and Teams has a live interpreter agent which, according to Microsoft, currently supports ten languages, but Polish is not among them.
What is Gemini 3.5 Live Translate?
It is Google’s model for real-time speech-to-speech translation, announced on 9 June 2026. According to Google, it recognises more than 70 languages. It works in the Google Translate app, and in Google Meet it is being tested with selected companies.
Is an AI translator safe for confidential documents?
It depends on the plan. Paid business plans (e.g. DeepL Pro, ChatGPT Business) state that they do not train models on customer data, whereas you should not paste contracts, personal data or trade secrets into free versions.
Will an AI translator replace a sworn translator?
No. A certified translation requires the signature of a sworn translator, who takes responsibility for it. AI can speed up their work, but it cannot replace the certification.
How much does an AI translator cost for a business?
DeepL Pro costs from 7.49 to 49.99 euros per user per month with annual billing, depending on the plan, and ChatGPT Business USD 20–25 per user. On top of that comes the time of the person checking texts published externally.
