Why continuing is harder than generating, and what this tool refuses to do
Writing from scratch and continuing someone else's draft are different jobs. When an AI writes from scratch it can use its own default voice; when it continues yours it has to imitate you: sentence length, tense, point of view, dialogue formatting, paragraph rhythm, whether emotion is stated or shown through objects. This tool reads those features from the text you paste and writes the next passage by the same rules. That is why short input produces poor output: to read a voice it needs at least two hundred words, and two or three paragraphs is better.
The continuation follows three rules. It never rewrites your last sentence; it begins with the sentence after it. It never introduces a new named character; it uses only the people present or implied in your text. And it does not leap ahead in the plot; only as much happens as can plausibly happen in the next four hundred words. If you give a direction it moves toward it without jumping to the resolution. These constraints are what make the seam invisible when you paste the result into your manuscript.
The direction line at the end of your input is optional but powerful. "→ next: it becomes clear her brother already knows what is in the envelope" tells the tool the outcome and lets it find the route. Without a direction, it keeps the existing tension and takes the safest path. If you are stuck because you do not know what happens next, run it two or three times without a direction and read the differences. If you know what happens but cannot find the sentences, give the direction.
We recommend against using the continuation as written. The real purpose of the tool is not to write your sentences but to get you past the stuck point. Reading a generated passage almost always produces a fast "no, not that," and that reaction is the signal that you already know the next sentence. Deleting half the output and rewriting the rest is the most common and the healthiest way to use it.
The free version accepts about 1,500 words of input and returns about 400, three times a day without an account. Your draft is not stored and is not used for training. Continuations that draw on a whole chapter and a story bible, with a target word count, are in the Studio.
