Ask a business question in plain language. Rifftest designs a rigorous survey, pressure-tests the wording, runs a free synthetic pretest in minutes, and fields it to verified physicians and patients — every number computed, benchmarked, and receipt-backed. And when the data can’t separate your options, it says so: “Statistical tie — don’t decide yet.”
The AI research tool that refuses to overclaim. When the data can't separate two options, Rifftest says so — and tells you exactly what it would take to find out. That honesty is the product: every number traces to a computed result, every synthetic read is watermarked, and anything unverifiable is withheld rather than guessed.
Free synthetic pretests, one-week Pulse decisions, full Standard studies, forecast-grade choice modeling, and trackers — with plain-English names, so you don't need a research translator. Designed, pretested, and fielded under one governed engine — quotes through your consultant.
The full study designer, watermarked synthetic results with verdicts and confidence ranges, norms benchmarking, reports, approvals, and the team workspace — try it behind the sign-in today.
Verified US physicians (M3/Sermo-grade verification) and advocacy-vetted patients, with live fielding QC, adaptive length, and pause/resume. Join the waitlist to field first.
KOL and expert interviews, fast qual, payer/market-access modules, caregiver research — stated honestly as roadmap, not silently absent.
Real-time AE detection in open-ends with a human-gated pharmacovigilance console and a 24-hour clock — the reason small teams who skipped patient research can finally run it.
Questionnaire → pretest → sample → fielding, each gate e-signed and bound to a frozen version. Change anything upstream and downstream approvals void automatically.
Fair-market-value documentation suitable for Sunshine reporting, passed through at vendor cost — the number on the quote is the number on the invoice.
