Show HN: AI Headcanon Generator: Instant Ideas, Endless Stories

I’ve been a fandom writer for a long time and also a very deep Tumblr user (like… headcanons, incorrect quotes, character analysis at 2am kinda deep). Writing has always been how I have fun w/ characters and stories I love.

I’m also a dev, and at some point I noticed smth pretty obvious: I love writing, but inspo doesn’t always show up when I want it to. Sometimes I really wanna write headcanons or relationship stuff, but my brain just goes empty lol.

So I ended up building a small tool for myself.

It’s an AI headcanon generator — you give it a few prompts, and it can generate character headcanons, relationship dynamics, random moments, or incorrect quotes. It’s not meant to replace writing or anything, more like a brainstorming buddy when you’re stuck or just wanna mess around.

I’m sharing it here bc it actually helped me get unstuck and made writing feel fun again, and I figured other fandom writers / Tumblr ppl might enjoy it too.

If anyone wants to check it out, here’s the link: https://aiheadcanongenerator.org/

Would love feedback, ideas, or feature requests — esp from ppl who live in fandom spaces.
