Your all-in-one AI copilot, right inside any Mac app
Chat with ChatGPT, Claude, Gemini, Grok and more in one client, with web search, file uploads, and side-by-side model comparison.
Select any text and a floating bar appears so you can rewrite, translate, or transform it instantly using built-in or custom actions.
Capture the active window, take a screenshot, or OCR text straight off the screen and ask questions about it immediately.
Generate, edit, upscale, extend, or remove backgrounds from images using leading image models such as Flux and Seedream.
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.
