validate your market, blazing fast.

What can you validate with Plastic in 10 minutes
Test more ideas before you spend traffic, sales time, or weeks building.
Surface what stops people from buying
Upload your offer, pricing page, or pitch copy and let your target personas name the specific doubts, risks, or missing information that would stop them from committing.
Find the right price points
Knowing how much to charge is always hard. See how your target segments react to your tiers, anchoring, and value framing before you lock in a number. Try different pricing schemes, including unconventional ones.
Sharpen your messaging
Test headlines, value props, and ad copy with your target personas. Know what lands and what falls flat before spending on distribution. Including the take you think is too absurd.
Review your landing page
Get honest reactions to your headline, copy, and CTA from your target personas before you drive real traffic to a page that doesn't convert.
Test a cold email or DM before you send it
Run your outreach message past your target persona and find out whether it earns a reply or lands in the trash — before you burn a list.
Stress-test an offer or proposal
Run your pricing page, service package, or client proposal past your target persona. See whether the scope, terms, and price read as clear and fair — before the real conversation.

Why Plastic feels real
Plastic applies frontier human decision simulation to model how different people judge, hesitate, and choose. The realism comes from deliberate constraints that keep every persona grounded in role, context, and lived experience.
Behavioral authenticity
Personas are pushed to react like people, not like polite assistants. They can be blunt, bored, skeptical, confused, or unexpectedly enthusiastic.
Knowledge boundaries
Each persona stays inside what they would realistically know. Outside that boundary, they hesitate, guess badly, or say it is not their domain.
Inner-voice prompting
Responses are framed as private thoughts, not polished interview answers. That brings out honest friction, hidden doubts, and real purchase resistance.
Repeatable synthetic research
The same personas can evaluate new materials under the same constraints, so you can compare changes without losing the underlying behavioral frame.
