You should allow around 45 seconds to 1 minute for each question asked, regardless of whether it is a scripted question or an AI Probing Question. The total time varies based on the number of questions in the interview.
Minimum:
Device with internet (computer, tablet, or phone)
Updated browser (Chrome, Firefox, Safari, or Edge)
Optional:
Microphone for audio responses
Camera for video responses
You can complete the interview entirely with text if you don't have a microphone or camera.
Yes. Works on iOS and Android. Fully responsive interface.
No. Everything runs in the browser. No apps, plugins, or account required.
Chrome, Firefox, Safari, or Edge. Any current version works well.
Not supported: Internet Explorer.
Yes, if the researcher has enabled language selection for the study. The interface is available in 64 languages, including right-to-left scripts such as Arabic, Hebrew, Persian, and Urdu (these are laid out right-to-left). You can usually pick your language on the welcome screen, and many invitation links open directly in the right language.
Yes. Responses are:
Stored securely with encryption
Accessible only to authorised research team
Not shared with third parties without consent
Subject to data protection regulations
That depends on how the study was designed. Check privacy policy before starting.
Three types:
Anonymous: No identifying information collected
Pseudonymous: Assigned ID, identity separated from responses
Identified: Required for incentives or follow-up
Research team conducting the study
AI analysis systems
The organisation commissioning the research (through the research team's reporting)
Not shared with public, marketing companies (unless disclosed), or other participants.
Yes. Same security as text:
Encrypted during upload
Stored on secure servers
Access controlled
Transcribed automatically
Retention defined by study terms
Email [email protected] with the survey link and the name of the brand it claims to represent. Tellet reviews the report against the account that published the survey, including who commissioned it and what data protection terms are in place. If the survey turns out to be unauthorized, or the account fails to meet Tellet's data protection requirements, Tellet can remove the survey and suspend the account.
Yes. Close browser anytime. Progress saved automatically. Click link again to resume.
Limitations:
Must use same device and browser (progress is saved locally)
Cannot switch devices
Don't clear browser cache
You can return and pick up where you left off by clicking your interview link again on the same device. (After an hour of inactivity the interview shows as incomplete in the researcher's dashboard, but you can still resume it.)
No. Cannot edit after submitting. The AI asks follow-ups based on responses, so editing would disrupt flow.
What to do: Take time before submitting. Clarify in later responses if needed.
It depends on what response types the researcher has enabled for this study.
Possible options:
Text only
Speech only
Video only
Multiple options (you can choose)
If multiple response types are available, you can choose which one(s) to use. If only one option is available, you must use that type to participate.
Be honest. Say you don't know or that the question doesn't apply. This is valuable data.
Examples:
"I don't have experience with that"
"This doesn't apply to my situation"
"I'm not sure I understand the question"
No skip button, but can give brief responses like "This doesn't apply to me" and the AI adapts.
The system handles this gracefully:
You'll be notified and can resend your message
Your saved progress is preserved
Most common cause: Browser permission denied.
Fix:
Click camera/microphone icon in address bar
Set to "Allow"
Refresh page
See Troubleshooting Guide for detailed steps.
Try in order:
Refresh browser (F5)
Try different browser (Chrome recommended)
Clear browser cache
Try incognito mode
Check internet connection
Yes. Works on iPad and Android tablets.
Completion message displays
Input area disappears
Progress bar shows 100%
Cannot add more responses
Depends on study:
On-screen message (always)
Email confirmation (sometimes)
Panel credit (if via panel)
Redirect confirmation (if integrated)
During interview: Yes, scroll up.
After completion: Conversation visible on screen until you close browser.
Later: No access after closing browser.
Varies by study. Check your invitation or panel platform for specific timing information about when you'll receive your incentive.
During interview: Clarify in next response.
After completing: Contact researcher directly with:
Interview ID
What you want to correct
Additional context
Yes. AI conducts the interview and asks follow-ups in real-time. Human researchers review responses afterwards to derive insights.
Usually not. One participation per person per study. Prevents duplicate responses.
If you try again: Shows completion message, cannot submit new responses.
Exception: Longitudinal studies may invite return participation with new link.
Traditional surveys:
Fixed questions
No adaptation
Multiple choice heavy
Rigid structure
Tellet interviews:
Dynamic questions based on responses
AI asks relevant follow-ups
Open-ended conversation
Natural flow
Depends on consent and study design. Check privacy policy.
Possible reasons:
Clarification questions
Follow-up studies
Results sharing
Panel opportunities
Control this through opt-in/opt-out when available.
