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.
Chrome's AI sidekick that remembers every page you read
Describe a page you read weeks ago and TabX finds it even if the tab was closed, using semantic search that matches intent rather than exact keywords.
Mention any tab, stack, or journey timeline in the chat and get streaming answers grounded in and cited back to the pages you actually read.
Your visits auto-organize into named research sessions that can be reopened in one click, restoring every page in the chronological order you browsed them.
Open tabs automatically cluster into named, colored Chrome tab groups so you stay focused by topic without manual tagging.
