Guides
A rich, detailed backstory for a character — history, motivations, relationships and key events — for a novel, a game character, or a D&D campaign.
How to use it
- Describe the character in Extra instructions — species, role, personality traits, or a rough idea of who they are.
- Press Generate.
- Copy the result, or download it as a text file.
What it costs
This tool costs credits — the Generate button shows the exact price live before you run it. Credits reset daily, and a run that fails costs nothing at all.
Is what I type sent anywhere?
Yes — the text you type is sent to the AI provider that writes the backstory, because it's part of the prompt. Don't paste anything confidential into it.
