Graph over lists
Competitors return categorized lists. The soul of this product is the edge: anxiety ← caused by → unfinished report. Without real links, it is just another sorting box.
Project case
Live
Lülü
A shipped mind-clearing tool: dump whatever is in your head, let AI sort and connect it, and get back an interactive map — so the tangle becomes something you can see in five seconds.
Problem
The hard part is not listing things — it is seeing how they tangle.
At night the brain won’t stop: todos, guilt, half-decisions, random noise, all mixed. ChatGPT can spit out a list, then the thread vanishes. What I needed was one dump box that returns a picture of the mess — especially the links between a feeling and the thing causing it.
Product
Not another notes app — a sorter that draws relationships.
Lülü wraps a quiet shell around a fixed loop: pour everything out, AI extracts six kinds of items and cross-type links, then React Flow renders an interactive map you can click, check off, and export.
- Dump freely — voice or text, no format required
- AI sorts into todos, emotions, dilemmas, and more — then finds links
- Interact on the map, save locally, export PNG or Markdown
Key calls
Three product judgments that shaped the build.
Zero-friction dump first
Guest mode, no signup, no forms. When the brain is noisy, typing into fields is the barrier. One big box plus voice; structure is inferred afterward.
Quiet, not preachy
Copy and prompt stay non-judgmental: a sorting tool, not therapy. Wrong associations destroy trust faster than missing ones — edges stay sparse and explainable.
Scope
What I owned end to end.
From positioning and the analysis prompt to the React Flow canvas and local-first history: product judgment first, then a shippable web MVP.

Outcome
A live dump → map loop, and a clearer bar for “worth building.”
The product is live at mind.koocuu.com. The next filter is habit: when the head is noisy, will I open Lülü instead of another ChatGPT thread? Later work can connect extracted todos into the koocuu dashboard loop.
