Validate ideas without running a single survey
Type a hypothesis in plain English. Synthight scans every conversation you've ever had, returns the supporting and opposing evidence, and tells you exactly which customers back each side.
Your hypothesis
"Users abandon checkout because they can't see shipping costs upfront."
Probability of being true
High confidenceBased on 47 findings from 23 customers
"I got to checkout and backed out the moment I saw the shipping fee. Wish I'd known earlier."
"Honestly, didn't really care about the costs — I left because of the signup form."
Overview
Every product decision starts with a belief. "Users abandon checkout because of shipping costs." "Enterprise customers want SSO more than reporting." "Our onboarding is the biggest churn driver." Each one deserves evidence before it becomes a roadmap bet.
The old way to validate: write a survey, find respondents, wait two weeks, get a 12% response rate, squint at a bar chart. The cost is high enough that most hypotheses never get validated at all — teams just ship and hope.
Synthight turns your existing conversation history into an always-on research panel. Type a hypothesis, and within seconds you get a probability score, supporting quotes, opposing quotes, the customers behind each one, and a summary you can paste into a product brief. No new research cycle needed.
What you get
Natural-language hypotheses
Write hypotheses in your own words. No query language, no tag selection, no boolean operators.
Probability score
Every hypothesis gets a probability-of-being-true score, drawn from the weight of real evidence in your conversation history.
Supporting and opposing evidence
Both sides are always shown. You see the quotes that back the hypothesis and the ones that challenge it, side by side.
Customer attribution
Know exactly which customers support and which oppose. Reach out, segment by response, or bring them into a feature preview.
Confidence bands
Low evidence? Synthight tells you. No more pretending three anecdotes are a trend.
Save and revisit
Save hypotheses to track them over time. See whether the evidence shifts after a release, a pricing change, or a new cohort.
How it works
- 01
Write the hypothesis
Type it like you'd write a Slack message. "Users abandon checkout because of hidden shipping costs."
- 02
Synthight scans
Your entire conversation history — findings, topics, sentiment — is scanned against the hypothesis using semantic matching.
- 03
Evidence returned
A probability score, a confidence band, and sorted lists of supporting and opposing quotes are returned, each attributed to a real customer.
- 04
Act
Paste the summary into your brief. Reach out to the customers who support. Or challenge the hypothesis further.
Built for every team
Product
Validate roadmap bets in seconds. Kill weak hypotheses before they eat a sprint.
Design
Test whether a usability assumption is real before scheduling interviews.
Marketing
Validate positioning hypotheses against what customers actually say, not against what you hope they say.
Leadership
Pressure-test strategic beliefs with real evidence from real customers.
Frequently asked questions
Is this a replacement for user research?
No — it's a complement. Synthight validates hypotheses against conversations you already have. For novel, forward-looking questions, you still want dedicated research. It just means that research can be targeted at the hypotheses that actually need it.
How does the probability score work?
It weighs supporting and opposing evidence by relevance, recency, and volume, and maps the result onto a calibrated probability. Low evidence produces a clearly communicated low-confidence score.
Can I see the customers behind the evidence?
Yes. Every quote is linked to the customer, the conversation, and the finding it came from.
What happens if the evidence is mixed?
You see both sides with their weights. Mixed evidence is often the most valuable output — it means the hypothesis is more nuanced than the team assumed.
Can I save hypotheses to track over time?
Yes. Saved hypotheses re-run on fresh data and you can watch the evidence evolve.
