Hi Product Hunt! ๐ I'm Lucy, building haru from Tokyo.
I used to journal every dayโฆ but it felt like writing into the void.
Nothing remembered me.
Nothing connected my thoughts.
Nothing actually responded.
So I built haru.
It reads what you write, remembers it, and responds โ not like a chatbot, not like a therapist, but like something that actually pays attention.
Would love your honest feedback ๐

The mood calendar and auto-summary are a nice touch. Curious โ does haru ever surface past entries proactively, like "you felt the same way 3 months ago"?
Right now, haru already brings up past entries naturally during conversations. And Iโm currently building a more proactive version โ like surfacing similar past moments automatically.
That โyou felt this beforeโ experience is exactly what I am working for now.

Looks nice to me. Conversations with AI like ChatGPT or Claude tend to disappear and hard to revisit.
haru make it easy to find them by date, and It helps me to revisit my memories.

@r_s_kimย Thank you so much โ this means a lot ๐
That was exactly the feeling I had too.
Writing things down, but not really being able to come back to them.
