The lightest AI agent

Chat freely.
It organizes itself.

Just ask and talk with your AI, the way you always have. The organizing happens in the background, and comes back to you exactly when you need it.

Heads up: the app's interface is currently Korean only — an English UI is on the way. The screenshots below are the real, shipping app. If you'd like the English version, grabbing it now and telling us is the fastest way to move it up the list.
My Knowledge Café is built on A. Karpathy's LLM Wiki concept.

The limits of AI chat

Your AI conversations —
are they good enough?

Open the ones that ring true. You've almost certainly hit at least one.

The longer the chat, the blurrier it gets +
The first few turns are impressively sharp. But as the conversation runs on, context scatters — you never quite get to the deeper research or analysis, and it trails off into confident noise.
Open a new chat, start from zero +
So you open a fresh one. Everything you built up is gone: re-upload the files, re-explain how you want things done, rebuild the context from scratch.
Material piles up. Nothing gets organized +
Research with AI and the material multiplies — but sorting what matters from what doesn't is on you. It ends in copy-paste into a note app. A human is doing the filing.Social-policy researcher
Nothing is kept, so you can't trust it +
With no source documents behind it, the model answers plausibly from the wrong reference — and you have no way to check where it came from. You stop trusting it, push back, and eventually give up.Media planning lead

If you've already tried the other way

Powerful tools everywhere.
So why do they end up unused?

The organizing tool was too complex, so I quit +
You opened a note or knowledge tool. Powerful, everyone says — but it starts with folders, plugins and syntax, and the organizing is still your job. A few days in, it's closed. "Too complex, so I stopped using it" is how most of these end.Social-policy researcher
You already built your own Obsidian + LLM wiki +
You wired up the plugins — an LLM client, vector search, templater, dataview — and built a genuinely powerful personal knowledge system. We know, because we did it too.

Then the system became the work. Plugin combinations to maintain, updates that break the chain, an API change that quietly takes your embeddings offline. And the actual organizing — summarizing, linking, tagging — is still yours to do by hand. It doesn't grow; you garden it.

Everything here is what that setup does, minus the maintenance: install once, open it, and it works.DIY builder · developer
So — a heavy AI agent? That felt like a lot +
Maybe you looked at the agent frameworks everyone's talking about. But it means installing a pile of developer tooling, and letting an AI roam your machine on its own is its own kind of uneasy — and once you try it, it often isn't that different from a chat window.
Knowledge tools are too complex, a DIY rig is too much upkeep, and a full agent is too much. — We took the space in between: a lightweight path that only takes care of organizing your documents.

Focus on the conversation.
It organizes itself.

My Knowledge Café is an AI chat that builds your knowledge. Not a heavy agent — as light as a chat window, but the document work takes care of itself.

The problem
How it's solved
Context scatters
Conversations are organized and kept automatically — the through-line survives
New chat = start over
Relevant notes follow you in — no re-uploading
Nothing gets organized
What matters is summarized, filed and linked for you — no manual filing
You can't trust it
Answers show the documents behind them — you can check the origin
The tool is too complex
Open and go. No folders, no plugins, no syntax — just talk
You focus on the conversation. The organizing happens behind you — so the thinking moves forward instead of stalling.

Core ① It organizes itself

Chat, and it becomes
knowledge you own.

It doesn't end at question and answer. What you talked about is summarized, tagged and linked into documents on its own. Nothing to move by hand — your knowledge grows while you use it.

Files, pasted text and web sources are organized the same way.

Core ② · the one that matters

Don't go looking.
It comes to you.

Whatever fits the conversation right now rises next to it, on its own. Open a new chat and the relevant knowledge is already beside you — nothing to upload again. Pin what matters.

Pinned material never slides away on its own — you decide the thread.

Core ③ Your own AI

Your rules —
followed exactly.

Don't wait for the model to figure out your style on its own. One clear instruction is what makes it work properly. Set it once and it holds for the whole conversation — no re-explaining.

You don't start from a blank page. Common instructions ship as templates — take one, edit it like a document, done.
No instruction
