About Copy as Markdown for AI
What Is Copy as Markdown for AI
Copy as Markdown for AI is a Chrome extension that copies what you see on a page as Markdown instead of raw HTML or flat text. It lives in your browser, adds a few right-click options, and does all the work on your machine. Nothing gets sent to a server.
The job it handles is small but constant. When you copy from the web, browsers usually put plain text on the clipboard, so headings flatten, link targets vanish and tables turn into a mess of lines. That matters more now that people feed web pages into AI chats, where clean structure helps a model follow your source. The extension reads the live page for the fragment you picked and rebuilds it as portable Markdown.
Two limits are worth knowing before you install it. It's built for Chrome, so Firefox and Safari users need the source build rather than the store listing. And it only converts what you select or point at, so it isn't a reader mode or a full-page archiver. If you need the whole page, you right-click the page and convert everything at once.
Getting Started
- Install the extension from the Chrome Web Store and pin its icon so the right-click menu is easy to reach
- Open a page, select the text you care about, or right-click a link, an image or the page itself
- Choose a copy option such as Copy selected text in Markdown or Copy full page text in Markdown
- Paste the Markdown into your note app, doc, code editor or an AI chat prompt
- Open the options page to pick a conversion profile, change image and link handling, or set a keyboard shortcut

Key features
One-Click Conversion From the Right-Click Menu
The extension adds copy options to the browser menu, so you don't hunt for a toolbar button. Right-click the page to copy the full text as Markdown, right-click a selection to copy just that text, or right-click a link or image to copy it in Markdown form. Each action keeps the structure you'd lose with a normal copy.
AI-Ready Markdown Profiles
Three built-in profiles tune the output for different jobs. The AI-ready default cleans common tracking and redirect URLs, resolves relative links and keeps selections lean so they don't waste model context. Faithful Markdown normalizes as little as possible, and the referenced clip adds an explicit source citation to every copy. You pick a profile once and it applies to the rest of your clips.
Link, Image and Source-Note Handling
Instead of dropping link targets or image context, the extension resolves relative links, removes unsafe ones and keeps meaningful images where it can. When a selection would bloat an AI prompt, low-priority image URLs get summarized. If links or images were changed during conversion, it adds a source note so you aren't left with a silently lossy copy.
GitHub Flavored Markdown Support
The converter handles the pieces people actually paste, including headings, ordered and unordered lists, task lists, strikethrough, inline code and fenced code blocks with language detection. Simple semantic tables turn into Markdown tables, while merged or irregular ones fall back to a readable row list rather than breaking.
Offline, Local-Only Conversion
Every conversion runs in your browser at the moment you trigger a copy. The extension doesn't send page content to external servers and doesn't collect browsing data, which keeps private pages private. It only asks for the permissions it uses, like reading the active tab and writing to your clipboard.
Customizable Shortcuts and Settings
You can convert with a keyboard shortcut instead of the menu, and the default Option+C on macOS or Alt+C on Windows and Linux can be changed. Settings sync through your browser account when available, so a profile you set on one machine follows you to another. Custom formats and image and link behavior round out the options.
Pros and cons
Pros
- Free and open source under the MIT license, so you can read the code or build it yourself
- Runs fully offline, so nothing you copy leaves your machine
- Three conversion profiles cover AI prompts, faithful clipping and cited notes from the same tool
- Handles the details that break a normal copy, including tables, task lists, code blocks and link targets
- Lightweight, at about 55 KB, and works from the right-click menu or a keyboard shortcut
Cons
- Public builds target Chrome, so Firefox and Safari users have to install from source
- It converts only the selection or target you pick, so full-page archiving means converting the whole page at once
- Because it keeps selections lean for AI, some image URLs get summarized rather than kept, which can strip a visual you wanted
- A couple of older store reviews mention grabbing image alt text, a limit that shows up when you capture images in bulk
