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.
Highlight any passage, right-click, and get a ChatGPT-powered summary in a pop-up
Highlight text, open the context menu, and pick SimpliSum to generate a summary without leaving the page or switching tools.
Results appear in a small pop-up over the current page, so you can compare the condensed version against the original passage side by side.
The listing describes summaries built on advanced machine-learning and natural language processing techniques powered by ChatGPT.
Rather than truncating, the extension is designed to identify the most important ideas, concepts, and details in the selected text.
