Element / Region Capture

Click to capture a specific element or drag to capture a region. Reliable screenshots via html2canvas.

Pin Notes & Severity

Attach notes directly to UI elements and mark severity (minor → critical) to prioritize fixes.

PDF in Seconds

Export a tidy, stakeholder-ready report with screenshots, notes, and severity—no copy/paste.

Where it helps

UX Audits & Design Reviews

  • Map findings to Nielsen’s heuristics (or your own rules).
  • Keep evidence tied to the exact element.

QA & Pre-release Checks

  • Spot regressions fast with annotated captures.
  • Share clear, reproducible issues with devs.

Stakeholder Demos

  • Guide walkthroughs with pinned notes.
  • Export a polished PDF after the session.

Training & Onboarding

  • Teach heuristics with real examples on live UIs.
  • Standardize how your team evaluates UX.

How it works

The extension injects a lightweight overlay for element/region capture and a side panel for notes, severity, and heuristic mapping. Screenshots are created locally (html2canvas) and compiled into a PDF in your browser.

Quick start

  • Install the extension
  • Open the page you want to evaluate
  • Capture element/region → add note → set severity
  • Map to a heuristic (or your own rule)
  • Export PDF and share

Heuristic Mapping

Use built-ins (Nielsen’s 10) or customize your own categories.

Local-first & Private

No servers, no tracking—everything runs on your device.

Side Panel Workflow

Keep context while recording issues. Stay in the flow.

No data collected

We don’t collect, transmit, or sell personal data.

Works on any site

Evaluate internal tools, staging, or production—your choice.

Run faster UX evaluations

Capture, annotate, prioritize, and export—without leaving the page.
