AI Text Flagger

About

Why I built this

I’m tired of polished AI-written posts on Facebook, X, and news sites that quietly push division, outrage, or fake “heartfelt” stories.

A lot of people don’t realize how much of what they’re reading is generated or shaped by AI. I wanted a simple way to see when the wording feels synthetic so we can pause, think, and choose how much weight we give it.

What AI Text Flagger does

AI Text Flagger scans the page you’re viewing and gently marks text that looks AI-written or heavily AI-shaped.

Adds a subtle red strike-through and “AI?” tag on suspicious paragraphs or posts

Works on social feeds (Facebook, X, etc.), blogs, and news sites

Looks for classic AI / LLM phrases, over-polished “template” wording, and line-by-line social copy

Runs automatically as you scroll — no clicks needed

It doesn’t tell you what to think. It just gives you a visual nudge:
“Hey, this might be AI wording. Take a second look before reacting.”

How it works (in plain language)

This extension does text analysis only:

Checks for phrases often used by AI tools and AI-written articles

Detects “liney” posts where every sentence is on a separate line (a common AI social style)

Looks at sentence length and word patterns that are typical of LLM-style writing

It does not:

Read your personal data or login info

Contact any external servers

Use paid APIs or send text off your device

All checks happen locally in your browser.

Important limitations

This is not a lie detector or a perfect AI detector.

Some human-written posts will get flagged.

Some AI-written posts will slip through.

The goal is awareness, not judgment. Treat every “AI?” mark as a signal to slow down, not as proof that something is fake or malicious.

Who this is for

People tired of invisible AI shaping social media arguments and outrage

Readers who want a little help spotting scripted, generic, or over-polished text

Anyone who would rather think twice before sharing or reacting

If you hate how anonymous AI scripts are used to stir up division online, this extension is for you. It won’t fix the internet, but it gives you one more tool to see the patterns — and maybe respond a little more wisely.
