Chat with ChatGPT, Gemini, Copilot, Grok and Claude in one Chrome sidebar
Access ChatGPT, Google Gemini, Microsoft Copilot, Grok, and Claude from a single sidebar instead of separate tabs.
Switch models with one click from the top bar, or open two assistants side by side to compare their answers.
The official AI web apps run in a compact window that is lighter on CPU, RAM, and network than multiple full tabs.
Take one-click window screenshots or record short MP4 clips of the window, and use the built-in emoji keyboard.
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.
