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.
Summarize articles, blogs and YouTube videos with ChatGPT in one click
Turn any long article, blog post or YouTube video into concise bullet points or a short paragraph powered by ChatGPT.
Choose Short, Medium or Long output so the summary matches the depth you actually need.
Highlight a hard paragraph or concept and let TLDR rewrite it in simple, plain language with helpful metaphors.
Export summaries as a clean branded PDF that keeps the article title, source link and TLDR branding.
