π§ More than a standard Chrome highlighter
A traditional chrome extension for highlighting text depends on manual selection. This AI tool starts with your question, searches the material, and marks supporting passages automatically.
Key differences:
β Question-based search
β Concise responses linked to evidence
β Direct navigation to the relevant wording on the page
β Support for both web content and PDFs
β¨ Designed for focused reading
The sidebar stays beside the content:
β Ask a follow-up
β Keep the page visible while you review the result and its citation
β Clear the chat when you begin a different topic
β Highlight webpages for research, work, study, or everyday reading
π€ Frequently Asked Questions
β Can it answer general questions?
π‘ AI Highlighter responds from the web page or PDF currently open in Chrome. If the required information is missing, it should not invent it. References help you confirm what the material says.
β How do I highlight keywords on a web page?
π‘ Enter a keyword, phrase, or topic in the sidebar. The AI browser highlighter for Chrome finds relevant content, provides a concise result, and opens the cited passage.
π Read with context, not guesswork
Add AI Highlighter to Chrome and explore web pages or PDFs through natural questions:
π’ Get concise responses.
π’ Inspect the cited passages behind important claims.
π’ Move directly to the text that matters instead of scrolling through the entire document.
π’ Use text highlighter AI for reading, research, and document review.
