I'll Think About it Later
A new AI integrated journaling experience
A system that transforms how you write — spatially, emotionally, guided by questions that help you go deeper. Your thoughts become an explorable 3D world, revealing patterns and connections you couldn't see before.

The Challenge
Traditional journaling treats thoughts like a document: chronological, linear, one entry after another. But thinking isn't like that. You lose your thread, want to branch off, need to add context to something earlier—and the format fights you. It's hard to start, harder to sustain.
Understanding the Space
Thoughts branch and loop back. Linear writing forces one thread, abandons others. Memory clusters in space, not time.
Chronological order can't capture branching thoughts. There's a magic to wandering.
Atmosphere unlocks emotion. The system senses mood—night, fire, rain, calm—or you choose. Memory is feeling, not text.
what if journaling wasn't about capturing thoughts in order, but creating a space where they could exist, connect, and reveal themselves over time?
The Solution
A system that turns journaling into a spatial, AI-guided experience. You write. The atmosphere responds. The question vanishes after you answer, leaving only your thoughts. You can continue the flow, branch into new questions, or revisit earlier threads. Over time, a 3D world emerges - a spatial map of your inner landscape, where every composition is a place you can explore.
Key Features
Feature #1 — The Writing Experience
Writing intuitively means sometimes losing your thread. You get stuck or circle without clarity.
Words from your writing float faintly in the background. When you're stuck, press Tab — they come forward. Choose one, receive a question that helps you go deeper.
Write freely. Stuck? Tab → choose word → get question. Question vanishes, thoughts remain.
The Composition
I experimented with how questions should appear — pulsing, shaking, bold. Every variation pulled focus. The animations distracted from writing itself.
I stripped it down to something familiar: a journal page. Date, time, a small question at the top — then space. Just text and a blinking cursor that says "just write."
The initial layout worked for short entries. But what happens when users write longer reflections requiring scroll? Words floating on top and bottom would obstruct vertical movement, breaking the flow.
I moved all floating words to the sides only, keeping the top and bottom clear. Vertical space stays unobstructed for seamless scrolling.
Feature #2 — Navigating the Mind Map
Thoughts are messy — they branch, scatter, reconnect. Traditional navigation (breadcrumbs, trees, nodes) can't handle that.
Navigation is spatial. Move with arrows/W/S, Enter to step inside, Esc to explore. Compositions arrange organically—a new way to navigate.
Move with arrows, zoom with W/S, Enter to step inside, Esc to explore. No mouse—just spatial wandering.
Composition Focus
A rich 3D world is great for exploring. But when writing, it becomes distracting noise.
Enter: world disappears. Esc: world returns. Focus ↔ exploration.
Enter: everything disappears, only writing remains. Esc: world returns. Richness for exploring, clarity for writing.
Feature #3 — AI-Generated Insights
After AI analysis, semantically related words cluster into floating clouds. Each cloud has a central concept with satellite words orbiting it — showing emotional themes side by side.
Key insights are placed on rotating circular rings receding into depth. Longer texts get larger rings. Looking through the tunnel gives a sense of accumulated layered thought.
Words appear as they are written — unorganized, raw, filling the space. This is the unprocessed state before AI makes sense of it.
Feature #3 — AI-Generated Insights
Not everything you write carries equal weight. Some moments matter more. Some words hold emotional charge. But in the flow, it's hard to see which ones.
As you write, AI extracts insights and arranges them in the 3D space.

Feature #4 — Emotional Atmosphere
Sound and particles can unlock emotion in ways text can't. The challenge: creating atmospheres that adapt to your writing—comforting, energizing, reflective—without overwhelming.
The AI analyzes your writing for emotional tone — anger, love, sadness — and adapts the atmosphere accordingly. Five moods emerge: Night, Fire, Rain, Calm, and Underwater.

Building Tools to Build Faster
Particles have dozens of parameters. Tweaking JSON directly meant: change value, refresh, check, repeat. Painfully slow.
Live sliders, instant feedback. Found the feel, exported to JSON. Hours became minutes.
Design Language
Two typefaces create a clear distinction between system and content.
The contrast signals what's yours and what's the interface, keeping the boundary clear without words.
Used for user-generated content — journal entries, insights, emotional words.
Design for 3D Space
Figma designs worked in 2D. 3D was different. How to maintain precision with X, Y, Z coordinates?
3D grid system: Figma layouts → Three.js coordinates. Invisible structure keeps infinite space organized.
Bidirectional Design
Hebrew reads right-to-left. English reads left-to-right. Layouts needed to work naturally in both directions without compromising readability or hierarchy.
Designed both versions in Figma. The grid system mirrors bidirectionally—text, navigation, floating words all flip naturally.

Reception and Impact
Presentation
I presented Social Simulation as my graduation project at Bezalel — my first React project after months of intensive learning. The system was complex, so I ran extensive playtests to understand how it was perceived externally.
What I Learned
100 Days
Pressure reveals what matters. When time is scarce, you stop second-guessing and start deciding. I learned to trust intuition, cut features ruthlessly, and ship quick solutions that worked.
I'm stubborn. Hours debugging bring immense satisfaction when solved.
I realized I could build complex things alone; research, design, code in parallel under pressure.
GPT opened infinite possibilities. Learned: precise prompts, manage tokens, watch costs. People differ—some want flow, others structure. AI always surprises.
Future Potential
This is just the beginning. Social Simulation proves the concept — non-linear journaling in 3D space, AI as a guide not a replacement, spatial navigation that feels natural. But the real potential lies in what comes next.
Mouse input would make the system accessible to a wider audience. Keyboard-only navigation comes from gaming—adding mouse opens it up. It also enables more complex menus and cleaner screens. As features grow, keyboard shortcuts become limiting. Mouse feels essential for continued development.
