I read a lot of ArXiv papers on my Kindle Scribe, but other tools for sending PDFs to Kindle completely scramble math equations and tables.
I built PDFling to bypass that. It just takes the ArXiv URL and sends the raw, unharmed PDF directly to your device via Whispernet.
It's a simple scratch-my-own-itch project, but I figured others here might find it useful.
I'd love to hear your feedback :)
