Invisible Journal

Inspiration

This project began with a simple, human question: How are young people expected to process the world they’re inheriting?

One of our teammates, a parent themselves, reflected on how little space young people have to safely express themselves in an increasingly unstable world. From climate anxiety to social unrest, from comparison-driven social media to rising rates of depression, the emotional weight Gen Z and Gen Alpha carry is overwhelming.

Recent studies affirm this urgency. Gen Z is now considered the most anxious generation on record, with over 60% reporting experiences with anxiety or depression (1) . According to a 2023 study by NAMI and the Adobe Foundation, nearly half of young people (46%) turn to creative expression to reduce stress or process their emotions, yet the platforms they’re offered often prioritize visibility over vulnerability, and performance over presence. (2)

So we set out to build something gentler. A space where reflection isn’t judged. Where creativity isn’t content. Where emotions are explored — not performed.

What it does

The Invisible Journal is a private, digital sanctuary where young people can reflect and express themselves through journaling, visuals, and creative prompts — all guided by gentle, non-judgmental AI.

Designed to feel like a digital campfire circle, the platform invites users to go deeper than just “I feel bad,” offering quiet support through poetic reframes, visual interpretations, and emotionally intelligent questions.

Users can: ✍️ Journal through words, images and voice notes — with mood-based tagging to help identify and visualize emotional states

🤖 Receive gentle AI prompts that encourage deeper reflection — including metaphorical rewrites, image generation, and even musical tone generation inspired by mood and journal entries

🫂 Share anonymously to themed circles (like Work Anxiety, Overstimulated, or Creative Burnout) — or choose to keep everything completely private. Also invite users into a circle by sharing a unique code with them.

🧠 Unlock emotional patterns over time, with insights like “You tend to feel anxious on Sunday nights” to support long-term self-awareness

The experience is light, non-performative, and anti-addictive — giving users full agency over what they create, how they process, and who they share it with.

How we built it

React Native + Expo: Built with Bolt.new and expo-router for fast, mobile-first prototyping AsyncStorage: For local drafts and offline journaling

Challenges we ran into

🧱 Web-first patterns didn’t translate well to mobile: Using localStorage and window.addEventListener caused crashes in mobile environments. We had to re-engineer parts of the system to use mobile-safe APIs like AsyncStorage. -> able to deploy Linking shared journal posts across private journal and public "circles" required careful state and database syncing. -> able to deploy User authentication using Supabase took a lot of trial and error: we were able to record email entries including user verification, but initialization was looping -> not able to deploy

Accomplishments that we're proud of

Built a working, mobile-native journaling app with mood tracking, AI-prompted writing, and private/anonymous sharing in just a few days
Designed with emotional intelligence and intention
Created a user flow demonstrating both the new user onboarding experience and a returning user’s experience (and how that reflects in their journal entry flow)
Debugged and iterated through Bolt.new with little to no prior coding experience, guided by persistence, teamwork, and help from AI (!)
Conducted an original survey with 33 participants, using their insights to shape features around emotional expression, privacy needs, and creative support

What we learned

Coding takeaways

Learned vibe coding with little to no background in coding (!)
Started thinking like a product builder, consistently asking how backend rules affect user experience, caring to structure logic with fail-safes and graceful fallbacks
RLS policies = what user can see and do, depending on who they are. This is parallel to thinking in terms of “user permissions,” “custom views,” and “access levels” in UX.

User takeaways

Emotional expression is deeply important, but not easy to access Many participants said they want to reflect more, but struggle with finding the right words, knowing where to start, fearing judgment from others or even from themselves Prompting with creative metaphors or mood-based visuals can lower the barrier to reflection and reduce the pressure of "saying it right" in this case.
Users crave emotional clarity more than tracking Several responses indicated that while mood tracking is helpful, people are looking for meaning behind the mood, patterns over time, reassurance or validation. The “emotional insights” feature is highly aligned with this need, as it offers emotional intelligence over just data logging.

What's next for Invisible Journal

🎯 Deeper personalization through AI Integrating the OpenAI API to analyze individual journal entries and generate prompts tailored to a user’s emotional tone, recurring themes, and expression style — helping users feel understood, not just responded to.

🎨 Emotion-based visual & audio generation Enable users to see or hear their mood through AI-generated art and soundscapes, translating feelings into visuals or music that can help with processing and release.

🎙 Voice journaling Support for users who prefer to think aloud, especially useful for neurodivergent individuals, or those processing complex emotions.

🤖 Conversational voice AI for stuck moments An empathetic, non-judgmental AI agent users can talk to when they feel blocked — offering simple reflection questions or emotional grounding through direct dialogue.

🧪 Research & school partnerships Collaborate with educators and youth mental health advocates to study the real-world impact of reflective, creative expression — especially in underserved or high-stress environments.
