Description

Headcanon AI is a creative writing copilot specialized in in-character headcanons, scenario seeds, and AU prompts. It captures tone and personality while giving you granular control over style, tags, and boundaries. Built with Next.js, TypeScript, and a modern UI, it supports multilingual output and a transparent credits-based model via Stripe. Writers use it to ideate character dynamics, backstories, relationships, and TTRPG builds—then iterate quickly with structured controls. Whether you’re drafting fic, building OCs, or exploring AUs, Headcanon AI helps you move from idea to polished text faster without losing your voice.
