Instant HTML Preview Bookmarklet

In plain words

Instant HTML Preview Bookmarklet is a browser tool that renders HTML and SVG code directly from your clipboard in a new tab. Designed for developers who work with generated code from tools like ChatGPT, it eliminates the need to copy code into an IDE, save files, and switch to a browser. Users simply copy their HTML, click the bookmarklet, and see the preview instantly. The tool is particularly useful for quickly testing code snippets without manual file management steps.

Bookmarklet that lets you render a full HTML page with any included css and javascript that is currently copied to your clipboard. Also works for SVG code. Useful with ChatGPT Canvas - ChatGPT Canvas HTML Renderer from Clipboard.url

ChatGPT has recently released its canvas capability, which is great for generating and viewing structured content. However, it currently lacks the ability to generate direct previews of HTML or SVG code. This bookmarklet fills that gap by allowing you to quickly preview HTML content directly in your browser. Instead of copying your code into an IDE, saving the file, and refreshing a page, you can skip all those steps and jump straight to seeing your content live. Simply use the 'copy to clipboard' button on the ChatGPT or Claude interface, then click this bookmarklet to immediately see the content rendered as a full HTML page. It also works for SVG graphics, making it versatile for web…from gist.github.com

In the maker’s words, at launch

Hey HN, I recently found myself needing a quick way to preview HTML and SVG code without having to copy it into an IDE, save it, and then open it in a browser. ChatGPT's new canvas feature is great for generating code, but it doesn't provide a way to preview HTML directly. To solve this, I made a small bookmarklet…

  Review my project: MarkUp, a tool to draw on any webpage.2010 · markup.io · ▲90

  Here's the website: http://markup.io/ We created MarkUp at Medium to help make the QA process better for sites we're working on. Grab the MarkUp bookmarklet, go to some page in your browser, then click it to draw on the page. Publish to make a link you can share. We've tried similar tools like BounceApp, Notable, and Skitch. Everything else we found is screenshot-based or takes us out of the browser. We wanted something that felt quicker than screenshots and more integrated with the browsing experience. Instead of taking a screenshot, MarkUp snapshots the DOM in the current page, strips the…

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
