Work

I'm building PaperHouse, a digital notebook.

PaperHouse Web (English Entry)

Why?

  1. I want the best writing tool.

    Existing writing tools are not good enough. I'm talking about docs, notion, ulysses, typora, etc. Do not overlook this reason. Creatives are sensitive to interfaces; that's the space they live in and the brush they create with. As McLuhan said, the medium is the message. The tool you think with shapes what you can think. I see so much friction in today's creative process, and I hope to reduce that friction so humans can unlock more creative potential.

  2. I want an unified personal Google

    An idea I can't find again is an idea I effectively never had. I write a lot but my writings are everywhere. Yes I had an inspiration and wrote it down somewhere; where is it? Apple Notes, my notebook, Google Doc, …, Claude? There should be one unifying database for everything you've ever written, with semantic search and a connected graph. Good ideas can compound, which is why they must be in one place. If we can build that corpus, it will be the strongest personal context layer.

  3. I want a time machine of my mind.

    Every word you put down is a snapshot of a brain state that will never exist again. Brains are powerful, but they forget and they change shape. My family preserved a few writings from my childhood; reading them now I go like “How on earth did my thoughts go there?” I was visiting a fascinating mind that I no longer recognize. Thank God I still have that access; had we lost the writing, I would have lost the portal to go back in time. I believe my stories, my words, deserve the utmost respect. But that is too much work and responsibility on my shoulder, so I'd want a personal AI to help me with organizing and remembering. The more vividly we can reconstruct the brain state behind what we wrote, the closer we get to accessing a literal time machine.

Time Machine

To illustrate the concept of “time machine,” below are miscellaneous collections of what I wrote in certain years. Each era felt distinctively different.
