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.
Free, on-device AI tab grouping for a calmer browser
On-device AI sorts dozens of open tabs into logical categories automatically, so related research and reading stay together.
Instantly close duplicate tabs opened more than once, so the same article does not appear six times in your tab bar.
Clear out tabs you opened weeks ago and forgot about, so long-neglected tabs do not pile up.
Everything runs 100% locally, with the developer disclosing that no data is collected or sold, so your browsing chaos stays private.
