A goal-driven AI copilot inside Chrome that guides multi-step projects end to end
The popup walks you through multi-step workflows one stage at a time, so large projects stay organised instead of overwhelming.
When you start a paper or proposal, AI Mentor proposes reference material to review and helps shape a working outline.
It reviews grammar, structure and style as you draft, offering corrections and improvement notes inside the browser.
For skill building it assembles a curriculum of books, courses and resources matched to the goal you describe.
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.
