And the small things that add up

Built by students who wanted one calm place instead of five tabs.

Focus timer that follows you: Pomodoro sessions keep running while you move between notes.
Planner that speaks English: Type “revise chapter 4 tomorrow” and the date sets itself.
Roadmaps per subject: List every topic in the syllabus and watch the progress bar fill.
Find anything with Ctrl+K: Search titles and the text inside every page, instantly.
Tabs, columns, full width: Open pages side by side and lay notes out the way you think.
Study with friends: Share a folder, write together, and see who's putting in the hours.
