AI proofreading that shows every change as a track-change you can accept or reject
Every AI suggestion appears as a tracked edit you can accept or reject one by one, so you never lose your original wording or voice.
Import .docx files, edit with AI and export them back with track changes preserved, including rich formatting like bold and italics.
Choose from grammar-only fixes to full rewrites on a graded scale, so a quick email and a formal paper can use the same tool differently.
Save your own editing instructions and apply them consistently across documents, from tone adjustments to domain-specific style rules.
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.
