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…

AI Headcanon Generator2025 · ▲8I’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…

Trickle - Magic Canvas ▲1,064Hey HN! Introducing Trickle Magic Canvas: the world’s first Agentic Canvas, where you can visually co-create apps and websites with AI, from idea to production. Why is a canvas better? Most AI tools today rely on linear chats or text prompts. We believe that limits creativity and clarity. Canvas changes the game. 1. Every version & page at a glance. Each page and sub-page lives on a timeline. You can quickly browse, edit, and preview progress like a living, visual document — no more digging through chat logs or scattered states. 2. The canvas is the context. Unlike linear chats, you can…

Today marks ten years, 3653 consecutive days, of running at least one mile every day under the USRSA rules [1]. To celebrate, I built an interactive dashboard that turns a decade of GPX files into charts you can explore. Running has truly changed my life: I've made lifelong friends, explored beautiful places, and more importantly invested into my own health and fitness, which I'm starting to see the positive benefits as I get older. The stack is pretty simple: a NextJS app, with a Postgres database to keep all my running data, and all the stats are pre-computed and cached in Redis, so I…

Made this website as an exercise in vibe-coding and GCP. It was posted about a few times around the internet, on sites like Morning Brew (https://www.morningbrew.com/issues/business-buzzkill), MetaFilter (https://www.metafilter.com/209703/Draw-A-Fish), boingboing.net, etc. I think it's cute! I built a basic CNN trained against penises and swastikas, and then anything that doesn't hit the 63% confidence score gets sent to a mod queue, a vibe-coded fish-tinder…

Hi HN - I made a site that takes a UK postcode, grabs the local MP's information and generates an AI mockup of what their ID might look like. It's a small, silly protest at the stupidity of the Online Safety Act that just came into force. edit - My open AI credits got hugged to death, please use a known postcode (like one from Kier Starmer's constituency, WC2B6NH) in the meantime.
