A research
panel that
never sleeps.
Drop in screenshots, name the persona you wish you could test with, and a panel of five testers will respond — in character, each tuned to a different cognitive bias — within a minute and a half. No recruiting. No NDAs. No two-week wait.
“Screen 2's primary CTA loses to the back arrow visually — copy says 'Continue', icon points left.”
“Empty state copy is friendly but doesn't tell me what to do first.”
“Information architecture mixes 'settings' with 'profile' — separate them.”
“I'd close this tab. It feels like onboarding designed for a deck, not for me.”
“I read this top-to-bottom and the value prop only landed at the third paragraph.”
UX research has the answers.
It just gets them too late.
By the time you finally have five real users in a recruiting tool, you've already shipped, scrapped, or rebuilt the thing. The feedback arrives in time to validate decisions you can't reverse.

Average cost of a five-participant unmoderated session round.
Of researchers say speed is the single biggest blocker to using UXR more.
The recruiting bottleneck
Brief recruiter, write screener, wait for slots, no-shows, reschedule — two weeks.
Persona dropped in. First model speaking in 4 seconds. Full panel done in 90.
One reviewer's bias
A single chat answer = one polite voice. You're back to one tester, not five.
Five testers, each tuned to a different cognitive bias. Where they agree is signal; where they disagree is interesting.
The pre-launch problem
Real users on unreleased designs = NDAs, leaks, and legal nervousness.
Screens never touch our database. Zero retention with model providers, by default.
Three steps.
No briefing meetings.
Built for the moment between “the prototype works” and “maybe we should test this” — the moment that usually disappears under deadline pressure.
- Step 01PNG, JPG, WebP up to 10 MB each.
Drop screens
Upload one screen, a flow, or two variants to compare. Drag to reorder. Label them so the panel knows which is welcome and which is checkout.
- Step 02Templates editable. Custom personas welcome.
Pick a persona
Start from a curated template — first-time user, busy SMB owner, skeptical trial user — then customize freely. The richer the persona, the sharper the read.
- Step 03Median: 78 seconds end-to-end.
Get five honest reads
Five testers respond in character — each with a different cognitive bias trained into how they read a screen. We synthesize where they agree, where they disagree, and the single highest-leverage change to make.
Five testers.
Five biases.
One read.
One reviewer is a focus group with one person. We assemble a panel of five testers, each tuned to a different cognitive bias — detail, structure, contrarianism, pragmatism, open-endedness. That's how you find both the signal and the disagreement, not just one polite read.
Reading 01 · Pragmatic
Tester 1 of 5Helpful generalist. Looks for usability friction first.
Reading 02 · Detail-oriented
Tester 2 of 5Reads copy like an editor would. Notices inconsistencies.
Reading 03 · Structured
Tester 3 of 5Thinks in flows and information architecture.
Reading 04 · Contrarian
Tester 4 of 5Will say what others soften. Less polite.
Reading 05 · Open-ended
Tester 5 of 5Thinks out loud, less hedged. Brings unexpected angles.
Each tester is powered by a different frontier model family, picked specifically for cognitive diversity. We swap models when better ones ship; the panel composition is documented end-to-end in our security disclosures.
Provider matrixYour unreleased
designs are safe.
We built UXRBuddy specifically for pre-launch work. That means the security pitch can't be footnotes — it has to be the product. Here's exactly what happens to a screenshot.

No database. No disk writes.
Screenshots travel from your browser, through our server's RAM, to the model providers. They are never written to a database, an object store, or a log line.
Provider-enforced no-training.
Every request is gated through Vercel AI Gateway with `disallowPromptTraining: true`. Requests only route to providers contractually committed to never training on your prompts. If no compliant provider is available, we fail loud rather than fall through.
Studies live in your tab.
Sessions are stored only in your browser's tab memory. Closing the tab deletes them. We don't sync them to an account, an analytics tool, or a marketing pixel.
Public links are explicit, expiring, and yours to revoke.
If you choose to share a study, we generate a short-lived link gated by your decision — not a default. We surface a clear warning before it leaves your machine.
For the moments
UXR usually skips.
Every research team has a list of things they know they should test and never quite get to. This is for that list.
- 01 · Pre-launch
Stress-test before recruiting.
Find the obvious confusions before you spend a week recruiting. Save real users for the questions only humans can answer.
- 02 · Variants
Pick a winner before the meeting.
Two design variants. One persona. Five testers. Walk into the design review with directional evidence, not vibes.
- 03 · Copy review
Audit copy through fresh eyes.
The fastest copy review you'll run. Five readers, each with a different tolerance for jargon, evaluating tone and clarity.
- 04 · Empty states
What does day-one feel like?
Empty states are where most products lose new users. Have the panel walk a freshly-signed-up persona through your zero-data state.
