一本会回信的书A book that writes back
写下问题，墨迹会回答。 Write it down.The ink answers.
白天正常使用。晚上写下问题，它用手写笔迹回答。天亮后，设备恢复。By day, it is your e-ink device. At night, the Book of Life wakes: you write a question, it reads, and answers in handwriting. At dawn, the device returns to normal.
白昼归你，夜晚归书。Yours by day. The book's by night.
开始定制Write your prologue→
写下「hi」，
它用手写笔迹回信。Write “hi.”
It writes back, by hand.
这不是效果图。字迹先淡去，回信逐笔浮现在同一块墨水屏上——一镜到底，没有剪辑合成。Not a render. The words fade, and the reply is drawn stroke by stroke on the same e-ink screen — one continuous take, no compositing.
“A small wind, and a leaf dancing.”
先定下它怎样回答你。Not any character. A book that first makes a covenant with you.
从一个问题开始。你选择它说话的方式、分寸和边界，最后确认成一份书契。Before it becomes yours, you bring one real question and discover the honesty, distance, and language you need. No technical parameters — only a covenant both of you can understand.
「明早面试，穿深色还是浅色？」“Dark or light for tomorrow's interview?”
“深色。 “Dark.
直接回答A concrete question, a straight answer
记得如何对你说话Remembers how to speak to you
它只保存你确认的书契与重要章节。普通问答不会长期保存。It keeps the covenant you confirmed and the chapters that matter — not every passing word as a permanent record.
每夜三答Three marks of ink
每晚最多三次正式回答。修改问题不计次数。Three formal answers each night. Revising a question costs nothing; only a completed reply becomes a page.
天亮恢复Closes at dawn
夜间进入人生之书；天亮后恢复阅读与日常功能。At night the device becomes the Book of Life. At first light, it closes and returns to reading and everyday use.
不用选择模型，只需要决定它怎样回答。Not choosing a model. Discovering the voice you are willing to hear for years.
你选择需要的回答方式、不能接受的表达，以及语言和边界。完成后生成一份可以修改和确认的书契。The prologue begins with one real question. The book asks what you need, how it should meet your avoidance, and which answers break trust. What emerges is not a hidden prompt, but a covenant you can read and revise.
写下问题Bring a real question
从一个正在困扰你的问题开始。Begin not with a personality test, but with what truly troubles you now.
选择回答方式Recognize the voice
选择温和或直接，以及是否需要判断和建议。Choose the balance of warmth, directness, questions, and judgment through real replies.
确认书契Confirm the covenant
确认关系、语言、边界和使用时间。Confirm relationship, language, boundaries, and rhythm before the book is bound to you.
合上是一本书，翻开才是一块屏。Closed, a book. Opened, a screen.
胡桃木、植鞣皮和黄铜会随着使用留下自然痕迹。It's closer to a wooden object that wears in with use than one more screen asking for your attention every day.
胡桃木 · 植鞣皮 · 黄铜 · 手工装订。Walnut · vegetable-tanned leather · brass · hand-bound.
