Show HN: Page Magic: Use AI to customize any web page

15 points by khaledh 2 days ago

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 any web page

- You can make the changes apply to the current page only or domain-wide

- You can see your prompt history for the page and toggle any of them

- Cost is tracked using Anthropic pricing and token counts (it may not be 100% accurate, but close enough)

Cost per change tends to be around $0.005 depending on page size.

Things you can try:

- Change the background color, text color, etc.

- Remove obnoxiously large hero images

- Reduce line spacing

- Increase content area width

- Remove stickiness of top headers

- ... anything you can think up
