The Keepsake Diary is a diary that writes back. Write as if you're writing in a diary and the page answers. Tom remembers what you told it over time, but you might not always like what he says :) Three ways to use it: - Ask: ask a question or write about anything and the page will clear immediately - Journaling: write for longer and control when the page will write back - Tom's Riddle: one riddle a day. guess it or get roasted Tom is an AI, not a real person. This diary may not be suitable for some minors. If you write about hurting yourself, the character stops and you are pointed to real help; how that works is published at keepsakediary.com/safety.
