Unsent
An app that learns to understand you,
through your own diary.
The more you write, the better it reads your patterns and feelings. A quiet place for the things you can't post on social media.
Your diary lives in your app — not in ChatGPT.
Write your diary straight from ChatGPT
Keep using ChatGPT as you always do — and save a diary right from it. Based on what you talked about, it's saved as a single entry.
The more you write, the better it understands you
As your entries grow, the AI understands you more deeply — reading the shifts and patterns in how you feel, in words that fit you.
Nothing stays in ChatGPT
Even during analysis, your diary is only passed to ChatGPT momentarily. Your records stay in Unsent — nowhere else.
If you can keep it up, the view changes
Here's the kind of change people notice once they start writing.
Before writing
- For some reason you're on edge, and nothing quite works
- You're too busy to keep it up
- The days wear you down, and no sense of being alive stays with you
After you start writing
- The AI puts your feelings into words. You see what's behind the irritation, and settle
- It's just talking, no pressure. A gentle nudge, and what never stuck starts to stick
- Even the smallest day stays, once written. The more it adds up, the fuller your days feel
Because you can keep going, small changes add up — and quietly reshape how you live.
FOR YOU
This might be for you.
Job seekers & new graduates
After the interview, talk to ChatGPT. It becomes your self-reflection journal. The more you write, the clearer your own story gets.
For job seekers →
The things you can't say at work
The meeting that wasn't fair. Things you can't say to colleagues or family. You can say them here — no audience, no blowback.
For working people →
Parenting, reflected back
Save something your child said today. The AI reflects how you see your child — and quietly, your own mind settles.
For parents →Also
Keep it close on your home screen
Add it to your phone's home screen to open it as an app — ready the moment you want to write.
Your past self, arriving unannounced
Now and then, a past entry quietly returns — a reminder that the unsteadiness isn't only today's.
A gentle reminder
For those who want to keep writing: on days with no entry yet, we'll nudge you in the morning, afternoon, or evening.
Share only with people you trust
Quietly share entries with the people you choose.
