A web page with a numbered callout on a button and a highlight across a line of text, the Simple MarkUp toolbar above it and the notes panel beside it, listing what each numbered mark says

Mark the page

Highlight, call out, point, or frame.

Write the brief

Your words become useful context.

Send it yourself

Copy or export it to the AI tool you choose.

Say it once

Point to the page.

Mark the thing instead of describing where it is. The screenshot shows the page; your words show what you mean.

Five ways to point

Highlight. Call out. Connect. Frame. Label.

Choose the mark that matches the thought: text, sequence, relationship, region, or aside.

The handoff

The brief follows.

You hand the AI the screenshot, your words, and the element you meant. Copy the screen, copy the prompt, or export both.
