An open-source Chrome side-panel extension for chatting with your choice of AI models while you browse.
Open an AI chat alongside the page you are reading, without navigating away or switching tabs.
Attach one or more pages, or selected passages, as references so answers draw on your actual source material.
Connect directly to providers such as OpenAI, Anthropic, and Google using your own keys, and add more providers that follow supported API formats.
Save prompt templates to run frequent tasks in a single click.
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.
