Why teams use it

Real user research, minus the weeks of recruiting

Stop guessing why visitors drop off. Get the critique of a full UX panel on demand, as many times as you ship.

Catch conversion killers pre-launch

Surface the friction, confusion and trust gaps that make real visitors bounce — before you spend a dollar on traffic.

Predictive attention heatmaps

See where synthetic eyes land, where thumbs tap, and exactly where users hit friction on every viewport.

Prioritized remediation backlog

Every objection comes with a concrete fix and an estimated conversion-rate lift, ranked by severity.

10 distinct behavioral personas

Skeptics, skimmers, bargain-hunters and executives — each with real cognitive biases and risk tolerance.

A single Product Health score

Clarity, usability, trust, value and accessibility distilled into one benchmarked number you can track.

Any URL — even staging

Point it at production or a password-protected pre-prod environment and get a verdict in under 75 seconds.

How it works

Three steps, zero setup

01

Drop any URL

Paste a landing page, pricing page or full product. Pick a B2B or B2C audience and a viewport.

02

The swarm evaluates

Ten vision-driven AI agents render and scrutinize your page in parallel, each through its own bias.

03

Get a scorecard + fixes

A health score, attention heatmap, per-persona verdicts and a ranked backlog of high-leverage fixes.

The swarm

A panel of biased, opinionated users

Switch between a B2B software panel and a B2C consumer panel. Each agent role-plays a distinct archetype and reports what made them convert, hesitate or leave.
