More than one way to find it again

Element details, page route, and screen size keep each mark in place.

Context around the report

On paid plans, context replay includes the steps before the report, along with console errors and failed requests.

The original evidence stays original

Your team sees the original report. Sensitive values are filtered before storage.

Reading your own data stays free

View reports in the dashboard or API on any plan.

Two modes

Choose who is reporting.

Use the full QA reporter or a simpler form for customers. The site owner chooses the mode with one script attribute.

Developer modeFor QA teams
  • Pin an element or select an area
  • Draw marks and choose a report type
  • Pause recording when needed
  • Capture clicks, console errors and failed requests
  • Keep captured technical details redacted
<!-- The default mode -->
<script src="https://alpha.commentunderscore.com/v1/embed/comment.js"
        defer></script>
Consumer modeFor customers
  • Circle or draw on the page
  • Write a message
  • No technical controls
  • Keep only what the person draws and types
<!-- Add one attribute -->
<script src="https://alpha.commentunderscore.com/v1/embed/comment.js"
        data-comment-mode="consumer" defer></script>

Use the same script, project and reports list, with developer mode on staging and consumer mode on production.

Performance context

See the slowdown behind the report.

Coming soon to Team and Business, in developer mode only. Each report will show how the page performed for the person who filed it.

Preview with sample numbersDeveloper mode

Find the slow part

Markers on the live page will point to slow main content, a slow click and content that shifted.

Trace the blocking code

In Chrome and Edge, see the script and function behind a slow moment. With source maps, see the original file and line.

See the visitor’s experience

The measurements will come from the person’s reported slow moment, not a lab page load.

Developer mode only

The overlay will never run in consumer mode. Consumer mode records no background activity.

Markup

Marks that stay visible.

Pin, outline, draw, add an arrow, or add an ellipse in seven colors. Choose glow, high contrast, or a color-blind-safe palette.

Seven colors

Choose the color that fits your review. It stays with the mark.

Change how marks look to you

Choose glow, high contrast, or a color-blind-safe palette.

A color-blind-safe palette

The alternate palette keeps marks distinct for deutan, protan, and tritan vision.

How it works

From click to resolution.

Share a review link

Reporters open the link, mark the problem, and add a note. No account required.

Get the full report

Get the note, marks, page, element, and screen size in one report.

Replay the steps

Paid plans show the steps before the report. Typed input and passwords are not captured.

Close the loop

Assign, reply, and update the status. Reporters can follow progress from their link.

Team workflow

Keep the evidence with the work.

Review evidence in Comment, on the live page, in GitHub, or through MCP.

Create a GitHub issue from a report

Connect a repository, then create an issue from any report.

GitHub integration

GitHub is available now. Other listed integrations are not yet supported.

Give AI coding tools the evidence

MCP gives coding tools direct access to projects, reports, and evidence.

Capture from the Chrome extension

The extension captures on a configured site and shows when recording is active. On a site that is not set up, it offers to register it.

Check saved evidence against approved conditions

Approve checks, then run them against saved evidence. Comment does not rerun the site.

See the report on the real page

An on-page overlay displays reports as pins on the live site, with each mark back in place.

Help when you need it

Open the help center or follow a short guided tour inside the app.

Delete one report

Owners and admins can remove a report while keeping its capture session.

Privacy

Your page stays private.

Comment does not capture typed input or passwords. Sensitive values are filtered before storage. A report screenshot shows the page with the reporter’s marks.

  • A copy of the page’s text
  • Keystrokes or typed input
  • Pointer paths
  • URL query strings or fragments
  • Request or response bodies
  • Headers or cookies
  • Password or payment fields
  • Anything outside the capture window

The marked element can include up to 80 characters of its accessible name. Freehand marks are stored because the reporter draws them.

Redaction you control

Email addresses, tokens, card numbers, and other sensitive values are filtered before storage. Add your own terms for anything specific to your team.

You can tell when capture is running

Recording is visible and consented. Reporters can stop it before sending.

Export or erase your data

Export or erase reports from the dashboard under Settings, then Your data. The security page explains the deletion timeline.

Your data lives in the United States, in the San Francisco region, with no EU option. The data processing agreement covers EU and UK transfers.

Capture stays focused on the report.

FAQ

Common questions, clear answers.

What does a report capture?

Each report includes the marked element’s role and accessible name, page route, screen size, marks, and note. Paid plans add console errors, failed requests, and context replay.

Do reporters need an account?

Anyone with your review link can report without an account. After they submit, they receive a link to follow the report.

Will Comment slow down my site?

Comment runs from one deferred script and a single origin. It makes no third-party requests and sets no cookies on your domain.

Can I export or erase my data?

Export or erase reports from the dashboard under Settings, then Your data.

What does context replay include?

On paid plans, context replay includes the steps before a report, plus relevant console errors and failed requests. It never records the screen, typed input, passwords, or page text.

How will the performance overlay differ from Lighthouse?

Lighthouse and PageSpeed measure a lab page load. Coming soon to Team and Business, the performance overlay will attach a real visitor’s slow moment to their report and show it on the live page in developer mode.
