Every entry brings you
closer to yourself.
Just write the way you speak. AI sorts each entry into facts, feelings, thoughts and body state, and turns it into a journal that deepens your self-understanding — with gentle, CBT-informed feedback that never judges.

About the name "Yorishiro"
In old Japan, a yorishiro was a vessel in which the unseen could dwell. As your daily words accumulate, the outline of who you are comes into view. Yorishiro aims to be a modern vessel — where you, in your own words, gradually take shape.
