About ExplainTXT: Highlight text. Ask AI.
ExplainTXT — any page, explained.
Press ⌘⇧E (Ctrl+Shift+E on Windows) on any website:
• Nothing selected? Get a summary of the whole page — one line on what it is, then the key points.
• Text highlighted? Get a plain-language explanation of just that part.
Prefer the mouse? Highlight text and pick Explain or Summarize from the menu, or click the toolbar icon to summarize the page. ⌘⇧S also summarizes the page.
The answer opens in a sidebar right where you're reading. Ask follow-up questions without leaving the page. Choose your language and text size from your dashboard at explaintxt.com.
Works on articles, docs, contracts, emails, forums — anywhere there's text.
