A side-panel AI chat, image and writing assistant you plug your own API key into
Open an AI chat window beside the page you are browsing without leaving the tab or switching to a separate site.
Point the extension at any endpoint that follows the ChatGPT-compatible interface and authenticate with your own key.
Send images into the conversation and have the model read, describe or answer questions about what is in them.
Draft and refine text directly in the panel, handy for emails, notes and short copy.
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.
