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.
Save web content into boxes and organize it with AI-recommended tags
Drag any sentence from an article, blog, or document and it is saved instantly into the box you choose, keeping related material together.
The combined GPT-4 API and proprietary algorithm proposes tags matched to the context of each saved snippet.
The extension is built to work on both Korean and English web pages, so mixed-language research stays in one system.
Find saved material by tag instead of hunting through browser bookmarks or a long uncategorized list.
