MARK•R

Highlight any web text and query it with conversational AI, right on the page

Highlight-to-ask interaction

Selecting any passage on a page activates a dynamic icon and AI prompt field, so a question can be asked at the exact place you are reading rather than in a separate chat window.

Whole-page context

Responses draw on the surrounding article or page, not just the highlighted fragment, which supports deeper questions about argument, terminology and implications.

Inline content generation

Ask for an executive summary, a white-paper outline, slide talking points, suggested email replies or rewritten copy without leaving the browser.

Comprehension support

Explain difficult terms, unpack technical or legal jargon and request simpler phrasing, which helps with dense academic, medical and financial material.
