Studix.app - Study PDFs without losing focus.

I built @Studix to solve a problem I kept hitting while studying: constant tab switching. Reading in one place, searching definitions in another, asking AI in a chat, then coming back totally breaks focus.

Studix is a chapter-aware PDF reader. It detects chapters automatically and keeps everything inside the document: inline explanations, floating definitions, mind maps, notes, summaries, and quizzes — all scoped to the chapter you’re reading.

The goal isn’t shortcuts or answer dumping, but better understanding with fewer context switches. There’s a free plan if anyone wants to try it.

Happy to answer questions or get feedback.
