A prompt-polishing and chat-cleanup toolbar for ChatGPT
An Optimize button turns a rough, loosely worded prompt into a clearer and more specific question before you send it.
Ask ChatGPT to extend an unfinished answer with a single click instead of typing 'continue' yourself.
Shrink or open individual messages to get a bird's-eye view of a long conversation and a less cluttered workspace.
Removes the friction of the Show More button so the full chat history is visible immediately.
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.
