riff is a Chrome extension that helps you turn LinkedIn posts and comments into clean markdown. You can use that text with AI tools to draft a reply that fits the thread better.
It is built for people who want a faster way to read a post, understand the tone, and write a response that feels on point.
- A Windows PC
- Google Chrome
- A GitHub account is not required to use the extension
- Internet access for download and setup
riff works best on recent Windows versions such as Windows 10 and Windows 11.
- Go to the riff releases page.
- Look for the latest release near the top of the page.
- Download the Windows file from that release.
- Open your Downloads folder.
- If the file is a zip file, right-click it and choose Extract All.
- Keep the extracted folder in a place you can find again, such as Documents or Desktop.
- Open Chrome.
- Open the Extensions page by typing
chrome://extensionsin the address bar. - Turn on Developer mode in the top right corner.
- Click Load unpacked.
- Select the extracted riff folder.
- Chrome adds the extension and shows it in your extensions list.
If your release file is an installer, open that file and follow the on-screen steps. If it is an unpacked extension folder, use the Load unpacked option in Chrome.
- Open LinkedIn in Chrome.
- Go to a post or comment thread.
- Click the riff extension icon in Chrome.
- Let riff extract the post and comments.
- Copy the markdown output.
- Paste that text into your AI tool of choice.
- Use the result to draft a reply.
- Edit the reply so it sounds like you.
riff gives you a cleaner view of the thread, which makes it easier to spot the main point, the tone, and the angle of the discussion.
riff is designed to pull the parts of a LinkedIn thread that matter most:
- Post text
- Comment text
- Author names
- Reply order
- Thread structure
- Plain markdown output
This format makes it easier to reuse the content in ChatGPT, Claude, Gemini, or any other text tool that accepts markdown.
If Chrome does not show the extension right away, try these steps:
- Check that Developer mode is on.
- Make sure you selected the folder that contains the extension files.
- Refresh the extensions page.
- Open Chrome again and try the LinkedIn page once more.
- If the extension seems inactive, click its icon in the toolbar and pin it.
If the folder opens as a zip instead of a normal folder, extract it first.
For best results:
- Open a single post thread
- Wait until the page finishes loading
- Scroll through comments if the thread is long
- Run riff after the full discussion is visible
- Paste the markdown into your reply tool
- Review the reply before you post it
If a thread has many replies, it helps to focus on the top comments first. That gives you the main context faster.
A simple workflow looks like this:
- Find a LinkedIn post.
- Extract the text with riff.
- Paste the markdown into an AI editor.
- Ask for a reply that matches the post tone.
- Check the draft for tone and facts.
- Post the reply on LinkedIn.
This keeps your response tied to the actual thread instead of guessing at context.
- Use short prompts when you want a quick reply
- Ask for a professional, friendly, or direct tone
- Keep the original markdown if you want to edit later
- Compare the reply against the post before posting
- Remove parts that do not help your final answer
If the post has a strong opinion, read the comments before you draft a response. That often changes the tone you should use.
riff is useful when you:
- Reply to LinkedIn posts often
- Need fast context from long comment threads
- Want cleaner text for AI prompts
- Manage engagement for a brand or profile
- Review posts before you comment
- Prefer markdown over copied page text
- Check that you loaded the right folder
- Make sure the extracted files are still in place
- Reload the Chrome extensions page
- Try removing the extension and loading it again
- Refresh the LinkedIn page
- Open a post thread with visible comments
- Wait for the page to finish loading
- Click the extension icon again
- Open the full thread before running the extension
- Scroll further down to load more comments
- Try again after the page fully loads
- Check that LinkedIn did not collapse the replies
