Does Plain Markdown send my data to a server?

Page conversion runs entirely in your browser. AI actions send the relevant page content to our server for processing; nothing is stored afterward.

Can I restore a previous draft?

Drafts are saved per page and restore automatically when you reopen the extension on the same page.

Can I use Plain Markdown to prepare content for ChatGPT or other AI tools?

Yes. Convert any webpage to Markdown, then paste it into ChatGPT, Claude, or any LLM. Markdown reduces noise and tokens compared to raw HTML, giving the AI cleaner context for better answers.

What is the best way to copy a webpage for an LLM?

Use Plain Markdown to convert the page first. It strips ads, navigation, and clutter, giving you structured Markdown that LLMs parse effectively. Copy the output and paste it directly into your AI chat.

Plain Markdown Guide

Plain Markdown converts webpages into clean Markdown. Conversion runs in your browser with no account required. Built-in AI actions help you summarize and question the page, and destinations send the result to tools like Obsidian, Readwise, or Notion.

Getting started

Install from the Chrome Web Store.
Open any webpage with http or https.
Click the extension icon to extract and edit Markdown.

In settings you can also:

Theme: Choose dark or light.
Source info: Prepend the page title, URL, author, and publish date to the output.
Open behavior: Default to the popup, or open the floating panel directly when you click the icon.

Floating editor panel

From the popup, click the floating panel button to open an embedded editor on the page.

Editor

The editor hides Markdown syntax to reduce visual noise while you read and edit.

Heading marks (#), bold, italic, and strikethrough marks fold away when your cursor is elsewhere.
Link URLs are hidden, showing only the link text. Place your cursor on a link to reveal the full syntax.

Drafts

Changes are saved automatically as you type.
Drafts are saved per page and restore when you reopen the extension.
Click the reset button to discard your draft and re-extract from the page.

Keyboard shortcuts

Find & replace: Cmd+F (macOS) or Ctrl+F (Windows/Linux).
Open a link: Hold Cmd or Ctrl and click any Markdown link in the editor.

Actions

Analyze and question any page you're reading. Built-in actions include Summarize, Action items, Pros & cons, and Fact-check; you can customize them or create your own.

Click the actions button in the toolbar.
Pick a built-in action or type your own question about the page.
Results stream into the editor.

Free includes 30 AI actions per month. Pro raises that to 3,000 per month with a 200/day soft cap.

Customize or create your own actions in Settings.

Destinations

Send the converted Markdown straight to where you keep your reading and notes. Configure each destination in Settings.

Obsidian: opens the captured Markdown in your local Obsidian vault. The content stays on your device.
Readwise Reader: paste a Readwise access token to send pages to your Reader inbox with optional tags.
Notion: connect a workspace via OAuth, pick a parent page during consent, then send pages directly to your Notion. Content goes from your browser to Notion; we never see it.

Using with LLMs

Plain Markdown is a fast way to prepare web content for large language models. Markdown strips away ads, navigation, and formatting noise, giving the AI only the relevant content in a structured format that uses fewer tokens.

Convert any article, then copy the Markdown and paste it into ChatGPT, Claude, or any LLM.
Use the editor to trim irrelevant sections before sending to the AI.
Paste a YouTube URL into the extension to extract the video's transcript as Markdown.

Troubleshooting

Only http and https pages are supported. Browser internal pages won't work.
If extraction or the floating panel fails, reload the tab and try again.
