GistNode: AI PDF Reader

Ever read the same paragraph three times and still not get it?

That's exactly why GistNode exists.

It's an AI PDF reader built for people who read to actually learn — not just scroll through pages. Whether you're a student grinding through research papers, a professional going through reports, or just someone trying to get through a dense ebook — GistNode sits right beside you while you read and helps you understand what's in front of you.
No switching apps. No copy-pasting into ChatGPT. Everything happens inside your PDF.

What GistNode actually does
Just select any text and the AI jumps in instantly. Ask it to explain a complicated passage, get a quick definition of a term, summarise a long section, or ask your own question about it. It even analyses charts, tables, and diagrams — just tap on any figure and GistNode tells you what it means.

Every AI response is saved automatically. So if you understood something really well yesterday, you can go back and read it again today.
Reading the way it should feel
GistNode is built for long reading sessions. Smooth continuous scroll, adjustable text size, light/dark/sepia themes — it just gets out of your way and lets you read. Your position is saved automatically, so every time you open a document you're right back where you left off.

Highlights that actually do something
Highlight in 6 colours — yellow, pink, blue, green, orange, purple. Organise your notes the way your brain works. And the best part? Tap any highlight later and ask AI about it directly. Your highlights aren't just decoration, they become your study notes.

Bookmarks, search, and a full library
Bookmark important pages and jump back to them instantly. Search inside any document. Your entire PDF library lives in one place — sorted by recently opened, title, or page count — with auto-generated covers so you can find documents at a glance.

Turn quotes into shareable cards
Found something worth sharing? Select the text, pick a template — Academic, Midnight, Minimalist, or Vibrant — and export a beautiful image card you can post anywhere.
Great for students, readers, and anyone who loves sharing ideas.
