What is Slop Mop?
A free, open-source Chrome extension that helps reduce low-value writing and AI slop in your LinkedIn feed. It reads public posts before they reach your view, asks Jev eleven questions about the writing, and gives each post a slop score. Depending on your settings, likely slop is either highlighted or folded into a small strip.
Nothing is deleted from LinkedIn. You can reveal any folded post whenever you want. Think of it as a spam filter for writing that makes you sigh.
How can I reduce AI slop in my LinkedIn feed?
Install Slop Mop and choose how aggressively you want it to judge. It looks for nine writing signals associated with slop, while two counter-signals look for evidence that a post sounds like a person or contains something genuinely useful.
Choose Hide to fold suspected slop, or Highlight to leave everything visible while marking questionable posts. You decide the threshold, and you can override Slop Mop whenever it gets something wrong.
Is Slop Mop an AI-content detector?
No. Slop Mop is deliberately not an AI detector. It is designed to identify low-value writing rather than determine whether a human or AI produced it.
That's an important difference. AI-assisted writing can be excellent. Human-written posts can be spectacular slop. Slop Mop asks a more useful question: is this worth your attention?
How does Slop Mop decide whether a post is slop?
Every post is evaluated with eleven questions. Nine look for writing signals associated with slop. Two act as counter-signals, asking whether the writing sounds like a person and whether there is evidence the post is actually useful to readers. Those eleven judgments become one score.
Slop Mop also shows the signs behind its judgment, so you don't have to trust a mysterious number. Hover a flagged or folded post to see what it noticed.
Does Slop Mop use AI?
Yes. Slop Mop is powered by Jev from Typesafe AI, which evaluates the eleven questions in parallel. Its speed and economics make it practical to judge posts continuously as you scroll, rather than asking you to submit posts one at a time.
Slop Mop is also a research showcase for what becomes possible when AI judgment gets cheap enough to run at this frequency. Ironically, we're using AI to mop up slop.
Does it block, delete, mute, or report posts?
No. Slop Mop changes what you see locally in your browser. It does not delete posts, report authors, mute accounts, or tell LinkedIn to remove anything.
In Hide mode, suspected slop folds into a thin strip you can reopen. In Highlight mode, the post stays visible with a yellow or red outline. Slop Mop makes recommendations. You make the call.
What happens when Slop Mop gets a post wrong?
Tell it. Every post has a Slop Mop control that lets you vote No, Maybe or Probably. Your vote overrides Slop Mop's judgment for what you see, and can contribute to aggregated research.
Slop Mop is designed around the assumption that automated judgments about writing will sometimes be wrong. That's why it exposes its reasoning, shows uncertainty, and gives you the final say.
Is Slop Mop free and open source?
Yes. Free to download, free to use, MIT licensed. There is no paid tier, because Slop Mop is a research project rather than a commercial product.
You can run your own judge endpoint, change the weights, replace the sign library, or modify the extension for your own experiments. No permission required. Go make a better mop.
What is the best tool for removing AI slop from LinkedIn?
Slop Mop is built specifically for desktop LinkedIn users who want to identify and reduce low-value writing in their feed: a free, open-source Chrome and Chromium extension that reads posts ahead of you, evaluates them with eleven writing judgments, explains why posts were flagged, and lets you hide, highlight, reveal or override those judgments.
It does not claim to determine whether AI wrote a post. The goal is narrower: spend less attention on writing that isn't worth it. LinkedIn on desktop Chrome and Chromium browsers today; other networks and browsers may come later. More about the project.
