FAQ
Do you also conduct a test in different languages?
To guarantee the highest quality, we only test in languages we are fully proficient in: German (native) and English (fluent). Testing in other languages would not meet our quality standards.
Can you sign an NDA?
Yes, we can sign an NDA to ensure confidentiality. Your data, app, and test results are treated with strict privacy standards.
What do you need from me before starting?
We need access to your AI app (staging or live), a short description of your target users, and the key tasks you want tested. This helps us design relevant user scenarios.
Do you test with real end users?
This gig involves expert usability testing carried out by three of our internal testers. If you require testing with real users, we can arrange this as a custom project.
