When you leave a company, you forget people who mattered. Not intentionally - your last two weeks are chaos, and memory is a terrible retrieval system under stress. It Was Great Working With You analyzes your work calendar export and gives you a personalized farewell list — the colleagues you'd most likely regret forgetting, ranked by how closely you worked together. We read metadata only — attendee names, meeting frequency, recency. No company login. File is processed and not stored.
