Fujii builds exam-date calendar on AI agent Muse

The starting point was a recurring chore in the cram school: when end-of-term tests approach, students often do not know the dates themselves, yet the school wants to know them early because timing differs by school. Fujii had been opening each school's website one by one to check and organize the schedules, and wanted to lighten that work.

The build stayed deliberately small. The calendar lives in a Muse 'Space', draws on dates listed on official school sites, and adds a countdown plus reminders at two weeks and one week before each test. Fujii describes the appeal as having information he checks repeatedly gathered in one place, and says he will adjust it while using it day to day.

Fujii also reports that Muse suits this kind of use because an app can be added to a workspace without a project-folder-like location, so a needed tool can be made on the spot. He adds that for task and schedule management Muse feels far easier to use than GPT in his own usage, while still turning to GPT or Codex for long-form writing.
