Show HN: Empower ChatGPT: Enhanced Doc Q&A and Academic Reading

I've been using ChatGPT a ton for reading and analyzing documents—things like research papers, tech docs, code snippets. But I ran into a couple of hiccups:

1. Not enough functionality: ChatGPT's built-in document reading features weren't as smooth or user-friendly as I needed.

2. Costs: Other expensive services offered better features but wanted more money, even though they use the ChatGPT API behind the scenes. It felt kinda off to pay extra when I'm already a ChatGPT subscriber.

So, I created this Chrome extension Doc Insight that works directly in ChatGPT and offers following features:

Instant Document Preview: Upload and view documents right inside ChatGPT—no more juggling tabs or apps.

Auto-Generated Table of Contents: Easily navigate through long documents with a clickable TOC.

Real-Time Diagram Rendering: See diagrams and charts directly in your chat to simplify complex ideas.

Smart Prompts: Boost your understanding, generate and refine code in different programming languages, and test yourself with custom questions.

I'm continuously working on improving Doc Insight and plan to expand it to support other platforms like Claude, Gemini, and Poe.

Give it a whirl and let me know what you think! Your feedback would mean a lot and will help make it even better.
