Rubric applies hundreds of UX checks to your pages and tells you what to fix first. It predicts where attention lands, sends simulated visitors through the page, and measures the real ones. Built for agencies and freelancers who look after websites.

Building with a coding agent? Connect it over MCP →
Observed — Homepage uses technical jargon without explanation: 'MCP' (Model Context Protocol), 'corpus', 'audit', 'checklist' are not defined for unfamiliar visitors. Example: 'serves a curated UX corpus to coding agents over MCP' assumes knowledge.
Issue — The page lacks a low-commitment secondary path — only a single primary action with no fallback for visitors who aren't ready to commit yet.
A real audit, a predicted heatmap, a simulated visitor and live analytics, on our own site.
The rubric was the passage a scribe wrote in red so a reader could follow the text. Rubric does that to a page: before launch, and after it.
Hundreds of checks, up to 7 pages. Findings by severity, each with the fix.

Predicted
Where the eye goes, on desktop and mobile, before launch.
See how it works →
Simulated
Describe a visitor. A simulated one tries the page and says where it hesitates.
See how it works →
Real visitors, no cookies, and a weekly read of what to fix.
See how it works →Each finding has four parts: the issue, why it matters, what to do, and the references behind it. Paste the issue into a client report; hand the actions to whoever builds the fix.
The page lacks a low-commitment secondary path — only a single primary action with no fallback for visitors who aren't ready to commit yet.
Visitors not ready to act at the primary level have no way to engage; they leave instead of taking any step at all.
A discovery pass finds the pages worth auditing. It's part of the audit.
Behind a login too: you sign in yourself, nothing typed is stored.
Findings grouped by severity, each with the fix. Watch it happen live, step by step.
Claude Code and other MCP clients can call the same checks while they build. One command, approve in the browser, done.
