How I built Düşün: an app that consults history

Enes Demirel

The idea came from a question: if Atatürk were sitting across from me and I asked him something, how would he answer? I asked myself that one evening; by morning I was coding the answer.

Düşün is simple: you write your question, pick 2–3 great minds, and each answers step by step, in their own voice, with references from their own life. Sun Tzu builds strategy, Rumi looks at the heart, Steve Jobs demands focus.

The hardest part wasn't the technology; it was the voice. Making a model talk "like Atatürk" is easy — making it convincing is not. I wrote style rules for each figure and banned presenting invented quotes as real ones.

I tried four design directions: imperial edict, night council, modern studio, newspaper. Warm paper and editorial typography won — because the point isn't nostalgia, it's readability.

The typewriter effect isn't decoration: watching the answer being written creates the feeling of someone across the table. Same reason every answer is first person.

Sensitive topics get their own rule set: the app offers wisdom, not treatment — one of the steps is always seeking professional help.

Every answer can be downloaded as a card, with enesdemirel.com/dusun at the bottom. Each share brings a new question. That's the growth engine.

Next: more figures, an English version, and a map of question themes. Düşün is my first answer to what applying an idea looks like.

"Everyone has information; the difference is in who can apply it."
