Pillow serves your outreach in the participant’s language, and your Researcher Agent runs the whole interview in that language too. Add translations for your outreach, and each participant sees the message that matches their locale.
Localization goes beyond outreach: the agent conducts the entire interview in the participant’s language, and the chat interface is shown in that language too.

Add languages

1

Write your primary outreach

Your first outreach message is drafted for you. Review and adjust it.
2

Add the languages you need

Click Add language and pick a locale, or click Add all languages to cover every supported language at once. Each message is translated for you, and you can edit any of them.
Translations carry the meaning and tone of your primary message, so edit them the same way you’d edit the original.

​
How locale matching works

A participant’s locale is detected from their browser. Pillow then picks the outreach language in this order:
  1. Exact match: their locale matches one you’ve added (for example, fr-FR).
  2. Same language: a variant in the same language (their fr-CA uses your fr-FR).
  3. Your default: the study’s default language.
  4. English: en-US as the final fallback.

​
Viewing interview language

Each interview records the participant’s locale in its metadata, so you can segment your results by language. If an interview comes in a language you don’t read, translate the transcript while reviewing it. See Review interviews.
