Understanding is
where every tool begins.

理解,
是一切工具的起點。

RikaiDev (Rikai) builds open-source tools — human-led, AI-powered.
Humans own insight and judgment; AI handles execution and scale — together building what no one person could.

RikaiDev(理解)打造以人為本、AI 為力的開源工具。
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.

我們不是用 AI 把程式碼寫得更快,
而是用 AI 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.

Iteration, scale, and everything that can be amplified. The power goes to AI.

迭代、規模,以及所有可以被放大的事。力量交給 AI。

What a single developer can ship today. This doesn't replace people — it frees them.

03 — Color
03 — 色彩系統

Paper, ink, and a single touch of vermilion.

紙、墨,與唯一的一點朱。

The palette is restrained almost to black and white: warm paper-white as ground, ink-black carrying all structure and text. Color is reserved for "shu" alone — like the single red of a signature seal, powerful because it is rare.

色彩克制到近乎黑白:溫潤的紙白為底、墨黑承載一切結構與文字。彩色只保留給「朱」——像落款印上唯一的一抹紅,因為稀少而有力量。

05 — Naming System
05 — 命名系統

Every name is an act of human perception.

每個名字,都是一個人類知覺的動作。

RikaiDev's strongest identity asset is its naming. Each product takes a native Japanese word, carries layered poetry through its kanji, and lets the word's literal sense map directly to what the tool does. In an age where agents are everywhere and models get swapped out, the name always describes a human act — reading, seeing, watching over — not the technology of the moment. Technology ages; understanding does not.

RikaiDev 最強的識別資產,是它的命名法。每個產品都取一個日文和語、以漢字承載多層詩意,並讓「詞的本義」直接對應工具在做的事。在 agent 遍地、模型會被換掉的時代,名字描述的永遠是人的動作——讀、看、守望——而非當下的技術。技術會過時,理解不會。

Name in native Japanese

Take a real Japanese word; its lowercase romaji becomes the product mark.

和語為名

取一個真實的日文詞,以小寫羅馬字作為產品標記。

Kanji as body

Every name carries kanji, often with layered meanings (読み = 讀/詠/黄泉).

漢字為體

名字皆有漢字,且往往一字多義(読み=讀/詠/黄泉)。

Image is function

The word's literal sense maps directly to what the tool does (目線 → point of view).

意象即功能

詞的本義直接對應工具在做的事(目線→視角)。

The human is the subject

Names describe human perception and care; AI executes, the name is human.

以人為主詞

名字描述人的知覺與關懷;AI 是執行,名字是人。

Restrained letterforms

Marks are always lowercase sans-serif; kanji appear only in the seal and emblem.

克制字形

標記一律小寫無襯線;漢字只在印章與 emblem 出現。

cortex

An early, English-named forerunner, now archived. It reminds us that the naming law was set only afterward — from here on, always a Japanese name.

早期以英文命名的先行專案,今已封存。它提醒我們:命名法則於此後才確立,往後一律和名。

How to name a new product
命名配方
1 → Which single act of perception or care does this tool perform for a person? (read, see, watch over, harvest…)
2 → Find the Japanese word that carries that act; take its kanji.
3 → Make sure the kanji holds a second layer of imagery (the more poetic, the better).
4 → Fix a lowercase romaji as the product mark; the kanji goes into the vermilion seal.
The name speaks of the person; the tool only makes that act real.
1 → 這個工具幫人做的,是哪一個「知覺或關懷的動作」?(讀、看、守望、收成…)
2 → 找出承載那個動作的日文和語,取其漢字。
3 → 確認漢字有第二層意象可延伸(越詩意越好)。
4 → 以小寫羅馬字定為產品標記,漢字入朱印。
名字說的是人;工具,只是讓那個動作成真。
06 — Graphic Language
06 — 圖形語言

Thin lines, a square seal, and the breathing room of one stroke.

細線、方印、與一筆的餘白。

Line icons
線圖標

1.5px even-weight ink strokes, 2px rounded corners, square terminals. Monochrome, unfilled, no shadow.

1.5px 等粗細墨線、圓角 2px、方形收邊。單色,不填色,不加陰影。

Square-seal motif
方印母題

The vermilion square seal works as a repeating motif, with slight random rotation (±3°) for a handmade imperfection.

朱色方印可作為重複母題,微幅隨機旋轉(±3°)帶來手作的不完美。

Hairline grid
細線網格

Divide the layout with hairline rules instead of filled cards. Whitespace leads, lines support.

以髮絲級細線分割版面,取代填色卡片。留白為主,線為輔。
