Page Magic: Use AI to customize any web page

In plain words

Page Magic is a Chrome extension that lets users customize the appearance of any web page using natural language commands. Users can modify styles like colors, spacing, and layout, applying changes to individual pages or entire domains. The extension requires an Anthropic API key and tracks usage costs based on token consumption. It maintains a history of customizations that can be toggled on or off per page.

In the maker’s words, at launch

I built this Chrome extension (using Claude Code) to help me customize the style of web pages to my liking. It's not perfect, but it does a decent job most of the time. You will need to bring your own Anthropic API key and add it in the settings if you want to try it out. Features: - Use natural language to customize…

  Trickle - Magic Canvas 2025 · trickle.so · ▲1,064

  Hey 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…

  I think we all have a similar flow and pain with browsers and AI. Copy article, paste in Claude tab, come back to article, back to Claude, in circles we go. Anthropic has a Chrome extension, but my daily driver is Safari. So I made my own extension. It's not a clone as I've never used the Chrome version. One obvious change: the Chrome version I believe uses Chrome "request sidebar" thing. And Safari doesn't have that, so had to inject the sidebar right in the site html itself. There's been some fun things in here like figuring out the sidebar html/css sandboxing. Also there's an agent…

  I'm an airline pilot – I built interactive graphs/globes of my flights▲1,539

  Hey HN! Pilots everywhere are required to keep a logbook of all their flying hours, aircraft, airports, and so on. Since I track everything digitally (some people still just use paper logbooks!), I put together some data visualizations and a few 3D globes to show my flying history. This globe is probably my favourite so far: https://jameshard.ing/pilot/globes/all If you’ve got ideas for other graphs or ways to show this kind of data, I’d love to hear them!

  Workout.cool – Open-source fitness coaching platform▲827

  I was the main contributor to workout.lol, an open-source fitness app to easily build a workout routine. The project had traction (1.4k GitHub stars, 95 forks, ~20K visits/month), but was eventually sold due to video licensing hurdles. The new owner stopped maintaining it, and the repo went abandoned. Over the next 9 months, I sent 15 emails to try to save it : no replies. Feature requests & issues were ignored. The community was left with a "broken" tool let's say. I couldn't just let it die So I built the new version from scratch with the same open-source spirit, but a better…
