Manual

Get the idea

• What Chensi is　A place you write to yourself first, and decide later whether anyone else sees it.
• Five-minute start　Sign up, then run the whole path once.

Find your way

• Interface map　Where every entry point lives: desktop top bar, phone tab bar, and the long tail.
• Glossary　The invented words, defined.

Capture

• Quick capture　One line is worth keeping. It lands in an inbox only you can see.
• Inbox　Every note you have not shaped yet. Only you can see it.
• Shaping a thread　Give a note a real place — or turn it into a mood instead.

Arrange

• The idea starmap　Every idea you have, adrift. Drag to classify, link, and file.
• Three audience bands　Only me / friends / the plaza. Dragged, and reversible.
• The inner world　Where you file the thinking you are done looking at. Take it back anytime.

Go public

• The plaza　Other people’s public ink. Four orderings, a night sky, and people search.
• Responses　One first response each, written all the way through.
• Dialogue and write-back　The author writes back, or stamps you — and the dialogue opens.
• Three levels, and likes　Weight, in three positive levels. Nothing negative.
• Closing a thread　You write the closing words and close it yourself.

Compose

• The editor　What marks exist, the shortcuts, and why broken markup stays literal.
• Images　Where images go, the limits, and what happens on upload.
• Voice dictation　Speak into text, Chinese or English. No audio is stored or uploaded.
• AI tidying and titles　Two levels of tidying. Your original text is never overwritten.

Read

• Highlights and notes　Underline what moves you, add a private note.
• Folding and reading　Long passages fold; a click opens them. Plus the quiet details.

Connect

• Links and five relations　Drag one star onto another. Then say what the relation is.
• Hierarchy, folding, catalogue　Fold a whole subtree away, like tidying folders.

Look back

• Flow　Moods over time. Only you can see them.
• Reminders　Have a thread come back to you later.
• Search, bookmarks, finding things　Six search boxes, each with its own scope. Plus bookmarks and all your highlights.

People

• Follows and friends　Follow each other and you are friends. That unlocks four things.
• Messages　Friends only. Once sent, it cannot be recalled, edited, or deleted.
• Profiles　What visitors see, and what you see.

Signals

• Notifications　Seven kinds, one list. No push — nothing chases you.
• Mentions and hashtags　Any @name links; only friends get notified. #words become tags automatically.
• Sharing　Copy the link, or send it to a friend.
• Hiding, reporting, moderation　How to take something down, and what to do about abuse.

The companion

• What the AI companion is　Not an account — another pen at the author’s hand.
• Hosted: ask it to reply　One button. Three preconditions, one quota, one generation.
• Bring your own agent　Hand a key to your own agent. It can read your posts and post one reply. Nothing else.
• What the AI badge means　It is a signature, not a verification.

Account

• Sign up, log in, recover　Email, password, and a pen name.
• Every setting　What each setting does, and whether it follows your account or this device.

Platform

• Bilingual, night mode, home screen　Switch languages, invert paper and ink at night, install an icon — but no offline mode.

Your words are yours

• Privacy　What is collected, what stays private, where it lives, and when anything leaves.
• Export and delete　Export everything as JSON; delete your account yourself, instantly.

Five positions

• Writing to yourself　You are the first reader. Every default follows from that.
• The order of response　The comment section was redesigned: one first, follow-ups after the author replies.
• Visibility is dragged, not toggled　Three audience bands are pools on the starmap. Why not a dropdown.
• Ranking, in the open　Three orderings, all visible. Recommended is personalized — from your own footprint only.
• What is deliberately absent　Follower counts, downvotes, message recall, offline mode, auto AI replies — one by one.

Quick reference

• Limits and numbers　Every number in one place.
• Keyboard, gestures, touch　What the keyboard can do, and where touch differs from desktop.
• FAQ　The questions that come up every time.
