What is ExplainTXT?
ExplainTXT—explain any webpage, instantly. Press ⌘⇧E (Ctrl+Shift+E on Windows): if no text is selected, it automatically summarizes the entire page, starting with a single sentence summarizing the main topic followed by key points; if you highlight a specific passage, it generates an easy-to-understand explanation tailored to that section. Mouse-based operations are also supported—right-click the context menu to choose “Explain” or “Summarize,” or click the toolbar icon to trigger summarization; ⌘⇧S likewise provides a quick summary of the current page. Answers appear directly in a sidebar at your reading location, enabling continuous follow-up questions, while language and font size can be customized via the dashboard at explaintxt.com. It works seamlessly across all text-based web scenarios, including articles, documents, contracts, emails, forums, and more.
