Add feedback on any web page. Then hand it to your agent.

Review your own site the way you'd mark up a printout: pin notes, rewrite copy in place, strike what doesn't belong. Then copy one short Markdown review your agent can actually act on.

Add it to Chrome See a sample review

Free Chrome extension. No account, nothing uploaded.

A pricing page being reviewed: numbered comment pins on the Pro plan and the Business button, and the PageCrit panel listing comments, text edits and a removal with severity chips.

Feedback that lands where it belongs

Everything happens on the live page, and every note carries enough context for an agent to find the right file.

Hovering the Free plan card outlines it with a dashed border and a div.plan label, next to two placed pins.

Pin a note to anything

Hover to outline an element, click, type. Each pin follows its element as you scroll, and its number matches the note in the panel.

A review row with the Must fix chip selected.

Say how much it matters

Pins take the color, and the review lists the urgent things first.

A testimonial being edited in place, with the word Mondays in bold and an Editing text label.

Edit text where it lives

Click any text and type. Links and formatting around it stay put, and the usual shortcuts add emphasis.

The hero buttons outlined in red with a Remove div.actions label.

Strike whole sections

Remove hides a section on the spot, so you see the page without it. Restore it from the panel whenever you like.

A review your agent can act on

One short Markdown file. Each item says what to change and how to find it in your code: the exact text, the headings above it, a stable selector and a small excerpt. Never the whole page.
