Quick startHow to create a survey LOI estimate
1. Choose sample type
Select panel, client, mixed, or not sure. Results stay blocked until this is captured.
2. Add the questionnaire
Upload Word/PDF, paste text, or enter structured survey elements manually.
3. Review assumptions
Check flagged routing, loops, screenouts, randomized items, and open ends before finalizing.
4. Generate and export
Create the LOI estimate, compare point-model and benchmark timing, then export Markdown or CSV.
Sample Type
Required before final LOI calculation. Programmed LOI never receives the client multiplier.
Timing settingsBenchmark model and device adjustment
Questionnaire Input
Used on review/results screens and as the export filename.
Sample type has not been selected yet. You can review the parse, but results will not calculate until this is captured.
