Freemium · $8/moBrowser plugin to question highlighted web text with AI
What is MARK•R?
MARK•R is a browser extension that lets you highlight text on any web page and ask an AI about it in an inline text field. It considers the context of the whole page, and can help draft summaries, white papers or slide content from what you read.
Highlighting text opens a small icon with a text box for conversational questions, so you can clarify a passage or turn it into something new without leaving the page. Plans differ by daily call limits, how many characters you can highlight or type, and whether GPT-4 is available. A customized build is offered for organizations that need it.
