# UI review for designers and QA

> Verify the shipped UI matches intent on UI-affecting GitHub PRs. Evidence you can replay, not screenshot arguments alone. hello@diffraction.sh.

## TL;DR

Designers and QA often inherit the same bad loop: a PR ships, someone pastes screenshots into Slack, and the argument becomes taste plus pixels instead of whether the running product matches intent.

Diffraction is private MVP / design-partner ready UI review (product experience review) for UI-affecting GitHub PRs on web apps. Findings are aberrations with evidence you can replay or inspect. Tagline: See the full spectrum of every diff.

## Quotable definitions

Aberration (design / QA framing): a verified product-experience failure found while reviewing a running UI, backed by evidence a reviewer can replay or inspect, not a lone screenshot opinion.

UI review for intent: UI review checks whether the shipped experience still matches design and QA intent on the running PR head: flows, states, copy, and outcomes, not only whether a frame looks close.

## Problem for designers and QA

A broken layout can be one aberration. So can a path that looks fine in a still and fails when you click through. Diffraction's category is product experience review of the running change, not another visual QA tool.

Thesis: source correctness ≠ product correctness. Pixel sameness ≠ intent match either.

## What Diffraction gives designers and QA

Faster check that the shipped UI matches intent on UI-affecting PRs. Replay / recording-style evidence so you are not arguing from screenshots alone. Findings tied to what a user would hit: flows, states, outcomes.

## How it fits design and QA workflow

Fit at the PR boundary, not as a replacement for design critique or full QA cycles. This does not turn every PR into a full manual QA session.
