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.

An AI second brain for everything you read and watch
Ask questions about whatever you are browsing, and send summaries of the current page or a YouTube video to your memory with a single command.
Query your accumulated notes and past learnings in natural language and surface ideas you saved long ago when they become relevant.
Create, edit and organize memory notes inside a full rich text editor instead of dumping plain text into a list.
Synaptic AI turns your requirements into tasks that you manage on a Kanban board, connecting captured knowledge to actual work.
