Frequently asked questions
How should I develop this kind of scene?
List what the viewpoint character actually observes separately from what they assume. Plant a fair clue before a reveal; the reader should be able to reconsider an earlier detail without supernatural intervention.
Can I choose another genre here?
This page keeps Mystery as its focus. You can choose compatible ingredients. Use the main Writing Prompt Generator to switch genres or return to Curated Prompts.
How many ideas can I generate?
Choose 1–20 mystery ideas. Fully fixed ingredients may allow only one distinct result; the status explains a shorter batch. These are starting points, not guarantees of unique finished stories.
What happens when I change prompts during a sprint?
The independent timer keeps its remaining time. Start begins the selected 5, 10 or 15 minutes; Pause and Resume preserve time. Reset or changing the duration deliberately resets it. Reloading the page clears both prompts and timer.
Does the timer count my words?
No. There is no built-in editor or automatic word count. An optional personal goal records only the target you enter for this visit. Write and check your progress in your own notebook or editor. The timer measures elapsed time with a deadline, including time spent in another tab.
What is the opening line?
Build a Story Idea can show an optional opening tied to the selected conflict, plus a direction for developing that conflict. It is a starting point to adapt, not a finished scene or a guarantee of a unique line. Copy includes an opening only when you choose to show it.
Do you store my writing or send prompts to a server?
No. These modes run locally without an AI API, account or saved writing. The generated prompts and timer are kept in memory for this visit. Clipboard access happens only when you press Copy.
