Translation and localization

Every new market means rewriting every product.

Cernel writes each product in every language you sell in, in the words, spelling and units of each market, by rules you set once.

If one of these sounds like your next market, this page is for you.

  • Word for word

    Instead of

    Translations that come back literal, in the wrong language, or with the wrong word for the product

    • A translation tool
    • ChatGPT, one product at a time

    With Cernel

    Each language has its own prompts for grammar, terms and conventions, and each market can follow its own keyword list

    A translation keeps the rules of the prompt that wrote the original, such as length, tone and format.

  • Nobody reads it all

    Instead of

    Nobody on the team reads every language, so mistakes go live unseen

    • Customer service checking translations
    • Spot checks before a launch

    With Cernel

    You choose which values go live automatically and which get a review step

    Review steps check every value, in every language by the same rules, and only ask a person when something fails or needs a decision.

  • Every new market

    Instead of

    Every new market means rewriting and re-checking the whole catalogue

    • A copywriter per language
    • A spreadsheet per market

    With Cernel

    Add a language, and the same agents write it for every product in one run

    Per language, the text is written fresh, translated from another language, or skipped.

How it works

From one product record to every market, in five steps.

What happens between adding a market and its product pages going live, with nobody copying text between spreadsheets.

  1. Add your markets

    Add each language by its code, such as en_GB, en_US or de_DE. UK and US English are two markets, each with its own rules.

  2. Set the rules once

    Each language gets a prompt for writing and one for translating. An agent can add its own instructions for any one language.

  3. Plan the run

    Per language, write it fresh, translate it from another language, or skip it. Fix the plan for an attribute so it is always done the same way.

  4. Checked like the original

    Translated values go through the same checks as the original, and your team can filter Review to one language at a time.

  5. Back to every store

    Each language goes back to your shop or PIM as that language's version of the product, or out as a file per language.

Local wording

Translated word for word, searched for by nobody.

A word-for-word translation keeps the original's words, not the ones shoppers search for: a travel mug becomes a Reisebecher, while German shoppers search for Thermobecher. In Cernel each language has its own rules for writing and translating, and each market can follow its own keyword list, so every product page uses its shoppers' words. What shoppers search for in each market is on Market insights.

In and out

What you set, what you get, and what stays yours to decide.

Languages
Every language you sell in, each added by its code, and a language spoken in two countries can be two markets.
Per language
A prompt for writing and a prompt for translating, both yours to edit. Per run, per automation or fixed per attribute: write it fresh, translate it, or skip it.
One set of agents
The same agents write every language. An agent can add instructions for a single language, and the options in your value lists can be translated too.
You decide
You choose which values go live automatically and which get a review step; review steps check every value and only ask a person when something fails or needs a decision.
Goes out to
Back to your shop or PIM in each matching language, each store with its own languages, or a file and a shopping feed per language.

FAQ

Questions about translation and localization.

  • What is product localization?

    Writing a product's content for a market rather than only swapping the words: the terms shoppers there use, their spelling, units and number format. In Cernel each language has its own prompts for this, and every language is also a market with its own search demand.

  • Should a market be generated or translated?

    Both work, per language and per run. Generate writes the text from the product in that language under its generation prompt. Translate starts from another language, keeps the original prompt's rules for length, tone and format, and follows that language's translation prompt.

  • Do we need a separate agent for every language?

    No. The same agents work across all your languages. Cernel handles the language through your language settings, and an agent can add its own instructions for any single language.

  • We sell in English in the UK and the US. Can they read differently?

    Yes. UK English (en_GB) and US English (en_US) are the same language but two markets, each with its own prompts and its own search demand. The same goes for a language spoken in two countries, such as Swedish in Sweden and in Finland (sv_SE and sv_FI).

  • How do we check the translations?

    Translated values go through the agent's review steps too, so only what breaks a rule waits for a person. Where you want a person to read a market, filter Review to one language and go through that market's values. Each value shows the language it was translated from.

  • How do the languages reach our shop?

    Each language goes back as that language's version of the product, so content lands in the languages and markets set up in your shop or PIM. If you run several stores, each keeps its own languages.

Bring one product and the markets you sell in.

In a demo we write one of your products in your languages, with a prompt per market, and show you how each language is checked before it syncs.
