College Executive Function

College Executive Function (CEF) turns your syllabi, course documents, and calendars into a single, synchronized academic plan — so you spend less time managing your semester and more time studying. HOW IT WORKS • Import a syllabus, course PDF, Google Doc, or .ics calendar file — including from Google Drive, Dropbox, iCloud Drive, or other cloud storage apps enabled under Files • AI extracts deadlines, exams, and assignments — and flags each item's grade weight so you know what actually matters • CEF builds a study plan around your real schedule, respecting the study hours, breaks, and limits you set • Everything syncs to your Google Calendar automatically, two-way — edit an event on either side and it stays in sync BUILT FOR EXECUTIVE FUNCTION CHALLENGES If "just use a planner" advice never sticks because keeping the planner updated becomes its own project, CEF does the organizing for you: it reads the syllabus so you don't have to transcribe it, breaks big deliverables into smaller steps on request, and shows a running "Semester Health" view of what's due soon. YOUR DATA, YOUR KEY CEF is BYOK (bring your own key) for AI: you connect your own free Google Gemini API key, so your documents are processed under your own Google account, not a shared company account. Calendar data and source documents are stored locally on your device. CEF does not sell data or share it with third parties for advertising. FEATURES • AI syllabus & document parsing with grade-weighted study time allocation • Two-way Google Calendar sync with conflict detection • Task decomposition ("Break It Down") for large deliverables • Multi-source chat — ask questions across everything you've uploaded • Available on iPhone and iPad Not affiliated with or endorsed by any college, university, or Google.
