Upload any file into your ChatGPT chat for richer, context-aware answers
Pick a file and GPTEnhancer inserts its contents into the current conversation as numbered chunks, giving the model your material as context.
Handles text, markup and data files such as .txt, .md-style text, .js, .py, .html, .css, .json and .csv, plus .pdf documents and .png/.jpeg/.jpg images.
A configurable delay between chunks (eight seconds by default) keeps submissions readable and reduces rate-limit or formatting errors.
Add an instruction of up to roughly one hundred words that is sent before the file, so the model knows what you want done with the content.
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.
