Localised Stimuli lets you upload region or language-specific versions of your concepts and creatives directly within a single study. Each participant automatically sees the version that matches their language - no duplicate studies, no manual routing logic, no messy workarounds.

Why this matters

When you're testing a concept across markets, the stimulus itself needs to feel native to each audience. A creative that resonates in the UK might need different copy, imagery, or even a different product variant for Saudi Arabia or Turkey. Until now, handling that cleanly meant splitting your study - which fragments your data and doubles your project management.

Localised Stimuli keeps everything in one place, so your data stays unified and your comparisons stay meaningful.

What's included

• Upload localised versions of any stimulus - add language-specific assets directly to each stimulus variant via the new Localised Assets section

• Automatic language matching - during interviews, Conveo serves the version that matches the participant's chosen language without any manual routing

• Fallback to default - if a translation hasn't been uploaded, Conveo automatically shows the default version, so nothing breaks mid-fieldwork

• Works across all stimulus types - randomised, monadic, and sequential monadic designs are all supported

• Exposure balancing is unaffected - variant selection happens before language matching, so your experimental design stays intact

A few best practices before you launch

• Upload all translations before fieldwork goes live — mid-study uploads are possible but not recommended

• Use clear, consistent naming conventions across your stimulus sets

• Double-check that every variant has a localised version for each target language

One study. Every market. Exactly the right stimulus for each participant.
