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.
