Can AI Translate Texts?

By Hendrik De Winne Last updated: Lees dit in het Nederlands
Partly Partly. AI tools translate most business and general texts quickly and readably, from emails to product descriptions and manuals. For legal, medical, or certified documents, a certified human translator is usually required by law. For anything important, you still check nuance, terminology, and cultural fit yourself before you publish.

How to do it

For everyday translation work, you paste the source text into an AI tool, specify the target language, and give it context about audience and tone. Modern language models handle grammar, sentence structure, and common vocabulary well, and they work across dozens of languages without extra cost per language pair. This makes them useful for internal documents, first drafts of marketing copy, customer support replies, and technical manuals where speed matters more than perfect polish.

For recurring content, build a short glossary first: product names, brand terms, and industry jargon that should never be translated literally or should stay in the source language. Feed that glossary into your prompt every time. This keeps terminology consistent across documents and cuts down on the manual corrections you need to make afterward.

Microsoft Research analyzed 200,000 real Copilot conversations and found that translation work has the highest AI applicability score of any profession studied, at 49%. That matches what most translators report in practice: AI drafts well but still needs a human pass for accuracy, tone, and anything client-facing.

Step by step

  1. Gather the source text, the target language, and details about your audience and tone.
  2. Build a short glossary of brand names, technical terms, and words that must stay unchanged.
  3. Split long documents into paragraphs or sections before translating them.
  4. Give the AI clear instructions on register, length, and formatting to preserve.
  5. Compare the translation sentence by sentence against the original for numbers, names, and facts.
  6. Have a native speaker review the result, and use a certified translator for official documents.

Where it breaks down

Certified or sworn translations, the kind required for contracts, court documents, diplomas, and official certificates, must in most countries be produced and signed by a translator registered with a court or a national authority. AI output does not count, no matter how fluent it sounds. Check the specific requirement in your jurisdiction before you submit anything official.

Nuance, humor, poetry, slogans, and culture-specific expressions remain difficult. A literal translation of a joke or a marketing tagline often falls flat in the target language, so a native speaker should always review this kind of content before publication. Also watch confidentiality: do not paste contracts with personal data, medical records, or trade secrets into a public AI tool without checking how that tool handles your data. AI can also silently mistranslate numbers, units, names, or legal terms without any visible warning sign, so check figures and facts sentence by sentence against the original.

A prompt to start with

Translation prompt with terminology control

Translate the following text from [source language] into [target language]. Audience: [describe audience, e.g. B2B software buyers]. Tone: [formal / neutral / conversational]. Keep these terms unchanged: [list brand names, product names, jargon]. Preserve the original formatting (headings, lists, bold text). After the translation, list any sentences where you were unsure about tone or terminology. Text: [paste source text]

Frequently asked questions

Can AI replace a professional translator?

Not for official or high-stakes work. AI handles routine business and general text well, but certified translations for legal, medical, or government documents typically require a human translator registered with a recognized authority. For marketing, literary, or highly technical content, AI output usually still needs review by someone with subject expertise and native fluency.

How accurate is AI translation compared to a human translator?

For common language pairs and everyday text, AI translation quality is often close to human quality on grammar and readability. It weakens on idioms, humor, ambiguous references, and domain-specific terminology, where it can produce fluent but factually wrong output. The safest approach is to treat AI translation as a fast first draft that a qualified reviewer checks before use.

Is it safe to translate confidential documents with AI?

It depends entirely on the tool and its data policy. Free public AI tools may store or use your input to train future models, which is a problem for contracts, medical records, or trade secrets. Check the provider's data retention and training policy first, or use an enterprise version with a contractual guarantee that your data will not be reused.
