Will I be able to remember today properly as time goes by? What kind of day are other people having right now? AI automatically writes a story with photos to write today's diary. Share today with 'only me', friends, anonymous people while keeping your privacy. [AI Diary] AI writes story if there are photos, and creates images if there are story. However, You can write it yourself because it is the most honest diary when you write it yourself. [Shared Diary] If you are having another boring day, try sharing your diary with a friend or someone anonymously. It will feel new if you share your daily life that felt boring. [Protecting Privacy] You can set each diary separately so that it can be shared only me, with friends, or with everyone. Now, notes what happened today and honest thoughts. [Calendar Archive] The diaries written every day can be viewed by date on the calendar. It's like a record of my life, so I can look them up at any time by date, location, content, etc. [Creating a Storybook] You can create a storybook by categorizing the photos you posted each day by topic. You can set it up so that sometimes it's just for you, sometimes it's with friends, and sometimes it's for everyone to see. [Please set Permissions] For AI to write an automatic diary, ‘Photo Access Permission’ is absolutely necessary. If you set ‘Location Access Permission’, AI can write better. You can set 'ON' the 'App Push Notification' to receive notifications when AI writes a diary or when people talk to you.
