Long time lurker here. I'm kind of nervous to post this, but I built a tool for myself that I wanted to share with you.

Problem: I have A LOT of technical PDFs sitting around on my computer. I use ChatGPT a lot to deep-dive into the reading, but it was pretty distracting even with a split screen view, since I had to copy paste content from one window to the other.

Solution: A kindle-like reader that allows me to send context to a chat window and discuss more about it.

It has full portability through a sync file and uses your own API key.

Disclaimer: I'm a Product Manager and a Designer. This was 100% vibe coded in Cursor as a tool for myself, but I wanted to share it in case anyone might find it useful.
