ChatGPT in your Mac menu bar, inline and everywhere
Press a shortcut and a floating text field appears in the middle of your screen for an instant ChatGPT query, no window switching.
Type a trigger phrase followed by your prompt in any supported text field and MacGPT writes the answer straight into it.
Reach ChatGPT from the menu bar either through the website or natively with your own API key, without leaving what you are doing.
Copy an entire conversation as a clean, readable transcript instead of fighting with selection across the UI.
AI sidebar and browser agent for reading, writing and research
A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab.
Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material.
Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move.
Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions.
