The macOS productivity browser built around organised tabs and project spaces
Tabs live in folders that survive closing windows and restarting the browser, keeping each project's pages together across sessions.
Separate work, personal and hobby contexts into Spaces, and switch profiles on a per-tab basis to stay logged into different accounts.
Builds a visual, linked and searchable tree of your browsing journey so multi-source investigations stay navigable.
Always-on-top windows for videos, calls and tutorials, plus a sidebar that connects your everyday web tools without leaving the browser.
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.
