Know your survey results before you ask anyone
Build a survey and Synthight answers it with synthetic personas, modeled either from demographics you configure or from the real experience of your customers. Anticipate the results with up to 85% correlation to reality, and prove the survey itself is well-built before it ever reaches a real person.

Overview
Surveys are expensive to get wrong. By the time responses come back, the budget is spent, the audience is used up, and a single leading or ambiguous question can quietly skew everything. Most teams only discover a flawed survey after they have already shipped it.
Survey Simulations flips the order. You build your survey in Synthight and run it against a panel of synthetic personas first. Those personas can be generated from demographic profiles you define — age, role, region, segment — or grounded in the actual experience of your real customers, drawn from the conversations Synthight has already analyzed.
The simulation returns a predicted distribution of answers with up to 85% correlation to how real respondents behave, plus a critique of the instrument itself: questions that bias the answer, options that overlap, and paths that lead nowhere. You fix it before launch, not after.
What you get
Demographic persona panels
Define the audience by age, role, region, industry, or segment and Synthight assembles a representative synthetic panel to answer.
Personas from real customers
Ground personas in the documented experience of your actual customers, so predictions reflect the people you really serve.
Predicted result distribution
See the full answer breakdown per question, with predicted percentages calibrated to reach up to 85% correlation with real responses.
Survey quality critique
Automatically flags leading questions, overlapping options, double-barreled wording, and dead-end logic before you send it.
Side-by-side iterations
Tweak a question and re-simulate instantly to compare versions and converge on the survey that measures what you intend.
Ready to launch
Once the simulation looks right, export or send the validated survey to real respondents with confidence.
How it works

Build your survey
Write your questions and answer options in Synthight, or start from a template.
- 02
Choose your panel
Configure synthetic personas from demographics, or base them on the experience of your real customers.
- 03
Run the simulation
Synthight has every persona answer the survey and aggregates a predicted result distribution.
- 04
Review and refine
Read the predicted results and the quality critique, fix what is weak, and re-run until the survey holds up.

Customer success
Anticipate how your real customers will respond to NPS and satisfaction surveys before sending them.
Frequently asked questions
How accurate are the predicted results?
Simulations are calibrated to reach up to 85% correlation with how real respondents answer. They are designed to anticipate direction and distribution reliably, not to replace a real survey entirely.
How are the synthetic personas built?
You choose. Personas can be generated from demographic profiles you configure — age, role, region, segment — or grounded in the real experience of your customers as captured in the conversations Synthight analyzes.
Does this replace running a real survey?
No. It validates the survey and anticipates the outcome so you launch a stronger instrument. You still send it to real people — you just do it with far more confidence.
What does the quality critique check for?
It flags leading or loaded questions, overlapping or double-barreled options, missing answer choices, and logic that dead-ends — the issues that quietly bias real results.
How long does a simulation take?
Minutes. You can iterate on questions and re-simulate as many times as you need before committing to a launch.
