Riff is a Chrome extension that extracts LinkedIn posts and comments into clean, structured markdown. One click. Copy to clipboard. Paste into any AI tool to draft thoughtful replies that actually reference what people said.
The best LinkedIn comments add unique value. But with 30+ comments on every post, most people either skip reading them or end up saying what someone already said. Riff gives you the full conversation context so your reply stands out.
Click the link above, then click "Add to Chrome". That's it.
Tip: Pin Riff to your toolbar for easy access. Click the puzzle icon (Extensions) in Chrome's toolbar, then click the pin icon next to Riff.
Open linkedin.com and find a post you want to engage with. This works on:
- Your feed (scroll to any post)
- A single post page (click into a specific post)
- Your own posts (to reply to comments)
Before extracting, make sure comments are visible on the page:
- Click the "Comments" section on the post to expand it
- If you see a "Load more comments" button, click it a few times
- The more comments visible on screen, the more Riff can extract
Why? LinkedIn doesn't load comments until you open them. Riff reads what's on screen, not what's hidden. If you see "0 comments extracted" but the post has comments, this is why.
Click the Riff icon (purple speech bubble with music notes) in your Chrome toolbar.
You'll see a popup with a big button:
➡️ Click "Extract Post + Comments"
Riff will scan the post and show you:
- A mode badge (COMMENT or REPLY)
- How many comments were found
- A preview of the extracted content
- Click "Copy Markdown" (copies structured text to your clipboard)
- Open your AI tool of choice:
- Paste (Ctrl+V / Cmd+V)
- The AI now has the full context: post, author, all comments, timestamps
- Ask it to draft your reply or comment
See interesting post → Expand comments → Click Riff → Extract → Copy → Paste into AI → Post your reply
| Problem | Fix |
|---|---|
| "No LinkedIn post found" | Make sure you're on linkedin.com |
| "0 comments extracted" | Click to expand comments on the post first, then re-extract |
| Wrong post extracted | Scroll so the post you want is centered on screen, then try again |
| Extension not responding | Refresh the LinkedIn page (Cmd+R / Ctrl+R) and try again |

| Mode | When | What It Does |

LinkedIn uses hashed CSS classes on the feed page that change with every deploy. Riff uses two extraction strategies:
- Single post pages (
/feed/update/...): Class-based selectors that are stable - Feed page: Semantic DOM anchors (
role="listitem",aria-label,data-component-type) that survive class name changes
This dual-path architecture means Riff keeps working even when LinkedIn changes their frontend.
Contributions welcome! LinkedIn changes their DOM frequently, so selector updates are always needed.
Common contributions:
- Selector updates when LinkedIn changes their DOM
- New extraction strategies for edge cases
- UI improvements to the popup
- Bug reports with diagnostic output (click "Diagnose DOM" in the popup)

# Make changes → refresh extension → test on LinkedInIn music, a riff is a short, repeated phrase that forms the foundation of a song. On LinkedIn, your comment is your riff on someone else's melody. Riff (the extension) gives you the sheet music: the full post, every comment, all the context. So your riff actually adds to the song instead of repeating what's already been played.
