You write.
AI keeps you company.
A creative writing practice tool. You write a passage; AI explains, sentence by sentence, what could be better and why — then you revise it yourself. It never writes a word for you, and it never gives you a score.
The interface and the videos are in Chinese. Web · phone (add to home screen) · Windows / Linux desktop
Why write it yourself
Today's AI already writes better than most people. But language is something humans made, and we keep making it richer — because we still need to express our thoughts and feelings, and to talk with each other, and with AI.
Let AI handle the boilerplate: reports, notices, routine emails. What's on your mind, you have to write yourself. Let AI sit beside you — help you sharpen it, push your thinking one step further, and be your writing partner.
What it does
Prompt → draft → critique → the reasons why → follow-up questions → your own revision.
Inline notes that explain
Critique is anchored to your own sentences: which one, why, and which direction to take it. Mechanisms you can practise, not "vivid language".
Ask back
Not convinced by a note? Ask. The AI answers with your text and the context in view. Whether to change anything is your call.
29 classic drills
Plain description, point of view, subtext in dialogue, pacing, free indirect speech, openings, endings, cutting… adapted from Le Guin, Gardner, Goldberg and others.
The drill is the ruler
Pick a drill and the critique measures your draft against its constraints and success criteria. Save any "what to practise next" as a new drill.
No ghostwriting, no scores
No one-click polish, no leaderboard. AI only speaks after you have written; every word in your draft is yours.
Your writing is yours
Drafts are plain Markdown files; export everything as a zip any time. The admin page cannot see anyone's text. Deleted pieces go to a recycle bin first.

FAQ
Which models does it use?
In mainland China it uses DeepSeek (official API, processed in China). Elsewhere you can choose from dozens of models, including Claude, GPT and Gemini. Your account page shows roughly how many points one critique costs with each model.
How do points work?
1 point = US$0.001 of model cost, charged by actual usage. A critique with a cheaper model takes around ten points; with Claude Opus, a little over a hundred. A critique that fails entirely costs nothing.
Who can see my writing?
Only you. When you ask for a critique, that piece is sent to the model provider for processing; it is not shared with anyone else.
Can I use it offline?
The desktop app (Windows / Linux) keeps your writing on your own machine. You can sign in to sync, or connect your own model API. The web and mobile versions need a connection.
