+      "For a long time I was looking for an app to organize my university life — tasks, deadlines, exams, and grades all in one place. I tried plenty of to-do apps, calendar apps, and study planners, but none of them combined the features I actually needed without dragging in a lot of clutter I didn't.",
+      "So I built my own. KanbanApp is a native macOS app, written in SwiftUI with SwiftData, designed around the way I actually plan a semester: organized by semester and module, with the same data flowing into a board, a calendar, an exam list, and a grade overview.",
+      "The Board is a classic Kanban with three columns — To Do, In Progress, Done — but with drag-and-drop between columns, deadline-based sorting, urgency-tinted cards that get redder the closer the deadline is, and recurring tasks that automatically roll over to the next occurrence when completed.",
+      "The Calendar is a month view of every task deadline and exam date, color-coded by module, so I can see at a glance where the heavy weeks are.",
+      "The Exams tab keeps a per-module list of upcoming and past exam dates, with optional time-of-day precision for the ones that actually have a fixed slot, and a portfolio mode for modules that have several deadlines instead of a single exam.",
+      "The Grades tab computes a German weighted average on the 1.0–5.0 scale, ECTS-weighted, with a Bachelor/Master toggle and per-semester breakdowns, so I always know where I stand.",
+      "Semesters and modules are created inline from the toolbar and from the module pickers in each form, so adding a new module never pulls me out of whatever I'm doing. The active semester is remembered across launches, completed tasks are cleaned up automatically after a few days, and past exams disappear from the list on their own.",
+      "If you want to try it or build it yourself, you can find the installation instructions in the GitHub repository.",
