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.
Real-time bias and logical fallacy detection for your browser
Highlights loaded language, framing, and one-sided presentation directly on the news article or page you are reading.
Flags common reasoning errors such as false dichotomies, appeals to emotion, cherry-picking, and straw-man arguments as you scroll.
Offers opposing viewpoints and alternative angles so you can weigh a claim against more than the author's framing.
Works on YouTube, Vimeo, TED Talks, TikTok and other platforms by decoding video transcripts for bias, fallacies, and conspiracy-style rhetoric.
