Pricing

Flexible plans built for every stage of research.

Whether you’re running one quick test or dozens of experiments a week, Propensity Guru gives you two simple ways to pay:

Pay-as-You-Go for total flexibility.

Subscriptions for teams that run synthetic surveys regularly — with automatic savings and overflow tokens when you exceed your monthly allotment.

Option 1 — Pay-as-You-Go

“Only pay when you run.”

PackTokensPriceEffective cost/run
Starter100$10~$0.10
Pro500$39~$0.08
Scale2,000$129~$0.065

What’s included

  • Access to all concept categories (CPG, App Store, Paywall, Logo).
  • Full use of the research workspace—concepts, personas, panels, and reports.
  • Tokens valid for 12 months.

Perfect for

Freelancers, agencies, or small teams running ad-hoc product or creative tests.

Option 2 — Subscription Plans

“Predictable monthly research power — with rollover flexibility.”

PlanMonthly tokensPrice / monthOverage
Starter200$19 / mo$0.10 / run
Pro1,000$59 / mo$0.08 / run
Scale4,000$189 / mo$0.065 / run

How it works

  • Your monthly token allotment refreshes every 30 days.
  • Unused tokens roll over for 3 months, so you never lose value.
  • If you exceed your plan, you simply pay the standard per-run rate.
  • Cancel anytime — no lock-in.

Perfect for

Growing teams or recurring research programs who want predictable cost and ongoing access.

  • Test one concept on our demo persona before spending a cent.
  • No credit card required.

Why token pricing works

Synthetic consumer runs cost only fractions of a cent in compute, so we pass the savings to you. Each token buys a fully simulated survey response — complete with Likert-scale distributions, rationales, and persona context — at a fraction of traditional panel costs.
