Hi Product Hunt, 👋 I'm Ohlulu, maker of Sotto.
Why I made Sotto
While renting winter clothing and ski gear in Canada, I kept having to look up and convert measurements because the units were different from the ones I use in Taiwan.
Around the same time, my girlfriend, who was working at a jewelry store, told me how often people came in to buy a ring without knowing their partner's ring size.
It made me realize that caring about someone often lives in details that are easy to forget:
their shoe or ring size
a favorite flower
an allergy
something they once told you
So I made Sotto, a private notebook centered on people.
Each person gets a private page for practical details, favorite things, important dates, relationships, and notes. Sotto includes 100+ built-in fields, with Custom fields for everything that does not fit neatly into a template.
From remembering to discovering
Sotto began as a way to remember what you already know about someone. But remembering is only half of knowing a person. Caring also means staying curious.
That idea became Pick a Question.
It includes 300+ curated prompts across 17 categories, ranging from easy icebreakers to family, values, conflict, intimacy, money, and the future.
A few examples:
“So far, what's your favourite thing we do together?”
“When you're angry, do you say it straight, or use silence and cold?”
“What's the line your family said to you most as a kid?”
Pick one from someone's page, ask it in real life, and save their answer as a note. More sensitive prompts are clearly marked and include guidance for starting the conversation with care.
Sotto helps you remember what you already know about someone while giving you a reason to discover something new.
