Slopstop

slopstop highlights posts and comments that read like they were written by AI.

As you scroll LinkedIn and Substack, slopstop scores the text of each post or comment against a set of heuristics — formulaic phrasing, em-dash density, hedge words, "It's not just X, it's Y" patterns, and similar tells — and shows a small colored badge inline with the content:

• Green (0–29): likely human
• Yellow (30–59): mixed signals
• Red (60+): likely AI-generated

Hover any badge to see exactly which signals fired and how it was scored.

Where it works
• LinkedIn — feed posts, reposts, and comments
• Substack — full posts on /p/ pages, comments, and Notes

What it does NOT do
• No data ever leaves your browser. There's no server, no telemetry, no account.
• All scoring runs locally as you scroll.
• The only thing stored is your on/off toggle (chrome.storage.sync).

Honest disclaimer
Heuristics aren't proof. Polished, formulaic human writers will trip false positives, and a careful prompter can write below the threshold. Treat the badge as a smell test, not a verdict — that's why every score links to its reasons.

Permissions
• storage — to remember whether the extension is on or off
• activeTab — so the popup can read the score totals from the current tab

Open to feedback. If a badge looks wrong, the reasons shown on hover will tell you why — that's usually the fastest way to suggest a heuristic to add or relax.
