Hello everyone,
Today I created a project called mark.
It was born from a simple but persistent problem in my learning process. While learning through platforms such as MIT OCW, YouTube lecture playlists, Khan Academy, and other online resources, I often found myself losing track of where I had stopped — a lecture timestamp, a question number, or a concept that needed review.
Although I could record these moments manually in notes, PDFs, or by starring tabs, the process always felt fragmented, slow, and inefficient. It didn’t match the simplicity I wanted in my study workflow.
So I built something more direct.
mark is a tool designed to preserve your exact stopping point in any learning session, allowing you to return later without friction or loss of context.
I am currently using it myself as part of my daily study routine.
If you experience the same problem, you can try it here:
