CanonForge – spark weird headcanons with AI

Hacker News

Hey HN, I built a small side project: https://characterheadcanon.net/ It helps people generate oddly specific headcanons for fictional characters. You just enter a character name and a few traits or hints — it gives you back hidden motives, quirks, or backstories. The idea is not to replace writing, but to spark “what if” moments for fanfiction, OCs, or just for fun. Why? I write short fanfics sometimes, and I realized brainstorming headcanons takes time. So I thought: why not use AI to kickstart that process? How? It uses Claude Code (Anthropic) to generate text, built on Next.js + React, deployed via Cloudflare. It’s browser-based, free to try, and doesn’t need sign-up. It’s intentionally small and niche — for people (like me) who overthink fictional characters at 2am. Would love feedback: things to add, UX improvements, or if you’d actually use it. Here’s the link again: https://characterheadcanon.net/
