Side by side: a formal apology into german

The same input on GPT-6 Luna and GLM 5.3 Flash, as each answered it, unedited.

Translate this text. Keep every name and link exactly as it is and every number at its value, and give only the translation. Translate it into German. Make the translation formal.

How the inputs are scored

  • Back-translation: the translation must keep every name and number, be in the right language, and read back close to the original when another model translates it back without seeing it.

The inputs: a shipping notice into spanish, museum opening hours into french, a work message into portuguese, a formal apology into german, and idioms in a welcome note, into japanese. Every model gets the tool's own instructions and up to Pro's reply limit. The method is the same as our other test runs.

How to use the AI translator

  1. Paste the text to translate, up to 1,400 characters in a free run.

  2. Pick the language to translate into, and the tone.

  3. Press “Translate”. Without an account you see the start of the translation (1 free run a day, no account needed).

  4. Signed in, pick up to three models and get their translations side by side.

Tips for a better answer

  • Give it context

    Translate whole paragraphs, not single sentences: the model needs the context to pick the right word and the right tone.

  • Set the tone

    Pick Formal for customers, officials and anyone you'd address by surname; the translation then uses the polite forms the language has.

  • Let models check each other

    Signed in, run the same text on two or three models. Where they agree, you can trust it more; where they differ, that's the phrase to check.

  • Translate it back

    Translate the result back into your language in a second run. If the meaning comes back intact, the translation carried it.

What a good translation looks like

  • Every name and number kept

    Names, codes and links should come through exactly as they were, and numbers, prices, dates and times at the same value. A translation that changes 14:30 to 2:30 or drops an order number isn't one you can send.

  • Meaning over words

    Idioms should be translated by what they mean, not word for word. “Hit the ground running” has no literal equivalent in most languages.

  • The same tone

    The tone should match: a formal letter stays formal (usted, vous, Sie), a message to a friend stays casual.

  • A second opinion for what matters

    For anything that matters (a contract, a medical note), have a native speaker read it. Two models agreeing is a good sign, not a guarantee.

What's free, and what signing up adds

  • Without an account: 1 free run a day, on GPT-6 Luna, shared with the free message on our home page. It takes up to 1,400 characters, writes up to about 600 tokens (roughly 450 words), and shows you the start of the translation.

  • Signing up is free, with an email link and no card. The translation you ran comes with you as your first chat, and you get 5 free messages on almost every model (all but Claude Fable 5.1, Claude Opus 5.5, and GPT-6 Astra).

  • Signed in, it runs the same text on up to 3 models at once, the ones you pick, and shows their answers side by side; each model's answer is a message on your plan, and you can carry on in the chat.

More free tools are on the tools page, and what each plan gives is on pricing.

Questions

Is the AI translator free?

Yes. Without an account you get 1 run a day on GPT-6 Luna, shared with the free message on our home page: you see the start of the translation, and the rest when you sign up. Signing up is free and adds 5 free messages on almost every model in llmwise (all but Claude Fable 5.1, Claude Opus 5.5, and GPT-6 Astra), with no card.

Can I compare translations from different AI models?

Signed in, pick up to three models and the same text goes to each at once; their translations appear side by side, so you can pick the best or spot where they disagree. Each model's answer counts as one message on your plan.

Which languages can it translate into?

The ten in the list: Spanish, French, German, Portuguese (Brazil), Italian, Hindi, Japanese, Chinese (Simplified), Arabic and English. Signed in, you can ask for any other language in the chat.

Can it translate a document or a web page?

It translates the text you paste; it doesn't read files, links or pictures in a free run. Signed in, you can attach a PDF or an image in a chat and ask for a translation.

How do you check the translations?

Our test runs below give every model five texts to translate and check that names and numbers survive, the language is right, and the meaning comes back when it's translated back into English.

Which AI is best for this, in your tests?

Every one of the 15 models we ran passed all 5 of our AI translator test inputs, so choose on speed and price: GLM 5.3 was quickest, at 1.0 s a run on average. GPT-6 Luna, the model a free run is on, took 1.4 s. The table on this page has every model's result, what a run counts as on Pro, and the time it took.
