Writing assistant, with you in the loop
This is a real recorded session of a LangGraph writing agent turning a day in Harbin into a travel-journal piece. The agent pauses at three checkpoints — the interview, an outline gate, and a voice-critic gate — and waits for a human. Here, the human is you: at each gate, pick a reply. The forked paths (⑂) are real too, recorded by resuming the agent's checkpoints with a different answer.
The point isn't the essay. It's the shape of the collaboration: an agent that interviews before it drafts, and gates its own output behind your approval — not "ChatGPT writes an essay".
The writing-assistant repo is private while a public release is prepared — this demo is the tour. Check back soon.
“A January day in Harbin. Woke up to -25C, spent the morning walking the frozen Songhua River, ate street food on Zhongyang Street, and ended the night at the Ice and Snow World among the lit ice castles.”
From this one paragraph, the agent runs the whole pipeline below — pausing at three checkpoints to ask you.
