Artlier
An AI diary that answers each entry with a letter and a work of art.
Artlier is a private diary for iOS. After each entry, the app writes back. A short AI generated letter responding to what you wrote, paired with an artwork chosen to match your mood and story. Most journaling ends the moment you press save. Artlier treats each entry as the start of a quiet ritual. Over time, entries, letters, and artworks build into a personal collection that shows how your inner life changes.

Challenge
Diary apps help users write, then stop at storage
Diary and wellness apps are good at capturing thoughts. But once an entry is saved, nothing comes back.
No response, no interpretation, no reason to return. Writing becomes filing.
Art platforms have the opposite gap. They present works by category, artist, or collection, with no link to what the viewer is feeling that day.
Research
The problem was not a lack of diary tools, but a lack of emotional continuity
I explored diary apps, AI companions, museum collections, and artwork discovery flows to see
where each one drops the thread.
Journaling feels unfinished
Users can pour feelings into an entry, but most apps offer nothing back afterward.
Implication, each entry needs a response worth returning for.
Journaler
Users wanted a private place to write, but most diary apps stopped after saving the entry.
Art Discovery
Browsing was rich in information but empty of personal meaning. Every visitor saw the same works.
The goal
The goal was never another productivity diary. It was a private space where feelings are acknowledged, interpreted, and remembered through art.
My Role
I designed and built the entire prototype myself
As a solo designer and builder, I took Artlier from concept to a working iOS prototype.
I defined the product concept, user flows, and information architecture, then designed the UI and the two core flows.
The AI letter and artwork curation. I also designed the statistics and profile screens,
implemented Firebase authentication, and built the prototype for iOS.
Key Contributions
01
Product concept and positioning
02
User flows and information architecture
03
AI letter experience
Key Solutions
Three moments that make writing feel answered
Artlier follows one thread.
The user writes, the app responds, and art gives the feeling a shape. Each solution serves one step of that ritual.

Outcome
The prototype carries one entry through the full ritual
01
Sign in with Google or Apple
02
Write an entry in a focused writing space
03
Receive an AI generated letter based on the entry
04
View a recommended artwork chosen for that entry
05
Revisit records, curations, statistics, and profile settings
Reflection
Emotional products need both intimacy and structure
The hardest balance in Artlier was between depth of feeling and clarity of product. Too functional,
and the app turns cold. Too poetic, and no one knows what it does. Every screen had to hold both.
Two decisions kept it honest. The AI had to respond to the specific entry in a tone the user chose, or it would collapse
into a generic chatbot. And every artwork needed a stated reason, or curation would become visual matching.
Because diary content is deeply personal, privacy shaped the account, data, and settings design
from the start rather than being added later.
Building the prototype myself made authentication, data structure, API limits, failure states, accessibility,
and App Store readiness part of the design work. Next, I want to improve recommendation quality,
test the letter's tone with real users, and strengthen privacy and data controls.
