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.

Strengths & Pros

+Works inline on any page, so you never have to copy text into another tool
+Uses the whole page as context, not just the highlighted passage
+Low entry price with a genuinely usable free tier and clear plan differences
+Broad range of applications from study and research to summaries and email replies

Limitations

–The Free tier is tightly restricted to 3 Pro Searches per day and just 1 Deep Research query per month with no manual model selection.
–Power users requiring heavy agentic Computer runs or uncapped o3-pro/Opus-level research must jump from $20/month Pro to the steep $200/month Max tier.
–Synthesized summaries can still inherit inaccuracies if underlying top-ranked web sources contain outdated or biased reporting.
