Send one prompt to ChatGPT, Gemini, Claude and more — all at once
Write a prompt once and send it to several AI chats — ChatGPT, Gemini, Claude and others — with a single click.
The extension opens a pinned tab for every selected AI service, reusing existing tabs so your workspace stays tidy.
Your most recent prompt is stored automatically and can be copied to the clipboard for quick re-use or editing.
Choose exactly which AI chats receive each prompt, so you can run a quick two-model comparison or a broad multi-model sweep.
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.
