A free GPT-4 sidebar for reading, scraping, prompting and image generation on any page
Ask questions about the page in front of you — articles, docs, dashboards — and get GPT-4 answers grounded in its content.
Pull tabular content from a page into a clean, structured dataset suitable for spreadsheets or further analysis.
Run drafts through prompt-optimization models (BART-large-CNN summarization, prompt generator, prompt extend) to get sharper results.
Convert spoken input to text with OpenAI Whisper Large V2, and turn written prompts into images with DALL·E 2 or Stable Diffusion 2.1.
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.
