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.
One private, encrypted AI memory you can carry between ChatGPT, Claude, Gemini and the rest of the web
Saves conversations from ChatGPT, Claude, Gemini, Grok and Kimi into one shared library, so your history survives a change of assistant.
Push only the selected memory into the AI you are currently using, without moving or re-pasting an entire chat history.
Find saved items by keyword, tag, star or filter, or ask a natural-language question and let AI locate the relevant passage locally.
Memory is encrypted with a key only you hold and can be synced to decentralised storage, with optional verification on Unibase Explorer.
