Only the posts worth your time.

Slop Mop is a browser extension, free for one feed, that reads the posts in your feed before you reach them, judges the writing, and folds away what reads like slop. Nothing is deleted: a folded post reopens with one click, and every verdict shows the signs behind it.

Today it works on LinkedIn in desktop Chrome and Chromium browsers such as Comet, Brave and Opera. Microsoft Edge, Safari and Firefox are coming soon. X, Reddit, Facebook, Substack, Medium, email and the rest of the web are coming.

No. Slop Mop is a bad-writing detector. AI-assisted writing can be excellent and human writing can be spectacular slop, so it asks a more useful question: is this worth your attention?

An AI model designed for calibrated decisions answers twelve questions about each post in parallel: nine tells of slop, two counter-signals (does it sound like a person, is it useful to readers) and how likely it is to be human-typed. Reader response, counted from reactions, comments and reposts, is the third counter-signal.

The answers become one score out of 100. Counter-signals can only lower it. How the score adds up.

No. Slop Mop only changes what you see, locally in your browser. Hide folds a post into a strip you can reopen; Highlight leaves it visible and tints its mop icon yellow or red. Nothing is sent to LinkedIn and no author is ever reported.

Click the mop beside the post and vote: No, Maybe or Probably, or Not sure to clear your vote. Your vote overrides the score in your feed straight away, with or without an account. It also counts toward the community vote on that post: in full once you have an account, and as a hundredth of a vote while you're trying Slop Mop without one.

When your vote disagrees with Slop Mop's verdict, the post's text is saved and a person at Artimovo reviews it; the posts it got wrong become training examples for tuning the tells and the score. Nothing that leads to you or the author is saved with it: it judges writing, not people. You can't vote on your own posts: the vote panel doesn't appear on them. It will be wrong sometimes. That's why it shows its working and gives you the last word.

Slop Mop is free for one feed, with 250 checks a day, for good. LinkedIn is the first feed it reads; X, Reddit and Facebook are coming soon. Slop Mop XL, coming soon, takes the mop to every feed, the sites you read and your inbox, for $5.99 a month or $59.99 a year. It renews automatically until you cancel, and you can cancel any time.

No. You can vote from the first post you see, and your vote changes your own feed straight away. Without an account, each vote counts as a hundredth of a community vote, so a hundred trial votes add up to one. Free and XL accounts count the same.

Signing up makes every vote that browser has already cast count in full, so the votes you made while trying Slop Mop stick. Votes still can't be traced to anyone: the server stores how much each vote counts, never which account cast it. If you've used Slop Mop since its early versions (0.x), every vote you've cast counts in full.

The post text and its public engagement counts go to api.slopmop.lol to be judged. Your name and the author's name are never sent. The server keeps a one-way hash of the text, not the text, unless your vote disagrees with its verdict: then that post's text is kept for review and training. The privacy policy lists everything it stores.

Only with Slop Mop XL, through Slop Mop for Gmail and Slop Mop for Outlook, and only the emails you open or ask it to check. Personal details are taken out in your mailbox before anything is sent: names, email and street addresses, phone numbers, links, card and bank numbers, ID numbers and dates of birth become placeholders like [NAME]. We take every step we can to catch names written in the body of an email, but can't guarantee every one. Only what the sender wrote is sent, never attachments, signatures or the earlier messages quoted below. Spam, private, legal, health and transactional mail is skipped unless you check it by hand. Email text is never stored, voting isn't available for email, and email is never used for training. The privacy policy has the details.

No. Slop Mop never sees who an email is from or who it's to: the sender and recipient names and addresses are taken out in your mailbox before anything is sent. Slop Mop judges the writing in an email, never who sent it or who it's for.

The original version of the extension and judging server is MIT licensed and public on GitHub. Everything about it, and the link to the code, is on the open-source page.
