理 解
Human vision.
AI execution.
Real products.
RikaiDev (理解) builds open-source tools — humans own the insight and judgement, AI owns the execution and scale, and together they make something no one could build alone.
RikaiDev（理解）打造開源工具——人負責洞察與判斷，AI 負責執行與規模，一起做出一個人做不出的東西。
We don't use AI to write code faster. We use AI to build what one person couldn't build alone.
Human — Insight
人 — 洞察
Vision, taste, the decisions that truly matter. Humans set the direction.
願景、品味，真正重要的決定。方向由人來定。
AI — Execution
AI — 執行
Iteration, scale, everything that can be amplified. Hand the power to AI.
迭代、規模，所有能被放大的事。力量交給 AI。
Together — The product
共創 — 成品
Shipped in production. Not replacing people — freeing them.
在生產環境出貨。不是取代人，是解放人。
Six tools, one philosophy
六個工具，一套理念
clone it · read it · run itEvery name is a native Japanese word that carries layers of meaning through kanji, and what it describes is always human perception and care. As AI agents and MCP become everyday, these tools choose the human side — all MIT open source, local-first, privacy-first.
每個名字都是一個日文和語、以漢字承載多層意象，描述的永遠是人的知覺與關懷。當 AI agent 與 MCP 成為日常，這些工具選擇站在人這邊——全部 MIT 開源、本機優先、隱私優先。
Read and write your LINE from any AI agent — read the messages, and read the context too. An MCP server with E2EE, decrypted locally.
從任何 AI agent 讀寫你的 LINE——讀訊息，也讀懂情境。E2EE 本機解密的 MCP server。

The code is the proof.
Not slides, not a demo, not a Twitter thread.
程式碼，即證明。
不是投影片，不是 demo，不是 Twitter thread。
Everyone ships with AI now; the only difference is whether yours can be cloned, read, and verified.
If AI-native development works, you should be able to see it in the commits.
如今人人都用 AI 出貨；差別只在於，你的能不能被 clone、被讀、被驗證。
If AI-native development works, you should be able to see it in the commits.
All MIT. Clone it and it's yours.
全部 MIT。抓下來就是你的。
Every decision lives in the commits, laid open for you to see.
每個決定都在 commit 裡，攤開給你看。
Local-first, privacy-first — your data stays on your machine.
