About
Arc is an AI assistant that works on the screen you are already looking at, so you can summarize, listen, rewrite, chat, extract information, and automate tasks without copy-pasting or switching apps. On Android it appears as a floating sidebar over other apps, while on Mac it opens over any window with Control+Space. Arc reads the current screen only when you run an action and uses that context to produce summaries, answer follow-up questions, explain or translate content, and generate context-aware replies or rewrites directly inside text fields. Its AI Writer can fix grammar, draft replies, change tone, or turn notes into posts, then insert the result back into Gmail, WhatsApp, Slack, or other apps. Text to Speech reads articles, documents, and messages aloud with automatic language detection, while Smart Extract pulls structured details such as dates, contacts, links, addresses, and tracking codes from the screen.
