3A Copilot

AI copilot in your browser: translate selected text, summarize pages, and analyze emails in a side panel.

3A Copilot brings AI into every page you visit — without switching tabs. Select & translate Select any text and hover over the 3A dot for an instant translation into your language. Explain or polish it with one click, then ask follow-up questions, with optional web search. Email assistant for Gmail and Outlook Open the side panel to summarize an email, draft a reply, translate and analyze messages in other languages, extract action items and contacts, or check a sender and their company with live web research. Page tools Summarize any web page, pull out key points and financial figures, or review terms and risks in documents. PDF support Summarize and analyze PDFs opened in Chrome or previewed in Gmail. Email skills also read PDF attachments automatically. Your skills, your language Turn your own prompts into one-click skills. The interface and AI responses are available in English, Simplified and Traditional Chinese, Japanese, Korean, Spanish, French and Portuguese.
