How It Works
Three steps. Under 60 seconds. You'll know exactly what to fix.
Paste your copy
Ad, email, social post, landing page — anything you'd put in front of a real audience.
Pick your audience
SaaS B2B, DTC, Consumer App — or describe your own niche. The crowd matches who you're actually targeting.
See what they think
Engagement score, live feed reactions, ranked objections, and suggested rewrites. You know what to fix before you spend a dollar.
Stop finding out the hard way.
Most copy fails in the market because it was never tested before it got there.

What 200 people actually think about your copy.
Every signal a real audience would give you — before they get the chance to.
Simulated Social Feed
See the scroll-past before it happens
Your copy appears in a simulated feed. Skeptics scroll past. Fans share it. Critics quote the line that lost them. You see every reaction — before your real audience does.
Engagement Score
Know if your number is good or bad for your audience
Calibrated against real industry benchmarks. A 4.2% engagement rate means something different for B2B SaaS than for DTC. CrowdTest tells you where you actually stand.
Objection Map
The exact lines that will kill your conversion
The top reasons your audience won't buy — ranked, quoted verbatim, and ready to fix. See the objections before your copy hits real people.
Experiment Testing
Two headlines. One winner. Zero ad spend.
Same crowd, two versions. Run A/B tests, holdouts, or fake door tests against your simulated audience — before you commit a single dollar of real budget.
Format Modes
The score changes based on what you're writing
Ad copy, email, social post, brand launch — each format is judged differently. CrowdTest shifts how personas weigh your content to match what you're actually creating.
Dissenting Voices
The comment you didn't want — before anyone posts it
The harshest critic in your crowd, quoted verbatim. The exact line that would end up in your comments section. Shown to you privately, while there's still time to fix it.
Does the simulation actually match what real audiences do?
We ran 5 real campaigns through CrowdTest before they launched — then tracked what actually happened. Here's the comparison.
See the results →They fixed it before it cost them.
We rewrote our launch email three times based on CrowdTest feedback. The final version converted 2x better. Eight cents of simulation saved us from a $10k campaign that would have flopped.
The objection map flagged three things we'd completely missed. We fixed them before launch. Open rate went from 24% to 41%. I run every email through this before it goes out now.
I ran our Series A announcement through CrowdTest the night before we posted it. Caught three credibility red flags my entire team had missed. The coverage the next day was the best we've ever had.
