About this extension
Tellbuster points out the phrases that make writing read like AI, explains why each one stands out, and suggests a plainer way to say it.

Readers now notice phrases like "Let's delve into", "In today's fast-paced world" or "It's not just X, it's Y". Tellbuster finds them before you hit send, so you can decide what to keep.

Tellbuster is a linter, not a detector. It never says your text "is AI". People use these phrases too. It shows you what readers notice.

WHAT IT DOES
- Click the Tellbuster icon, paste your writing, and see each phrase underlined with a short note: why it stands out and what to write instead.
- Select text on any page, right-click, and pick "Check with Tellbuster".
- Optional: turn on "Check as I type" in the settings. A small badge shows up in text boxes on LinkedIn, X, Gmail and most sites when it finds something. Click it to see the notes.
- English and French, plus starter rules for Spanish, German and Portuguese. More than 100 rules in all.
- Turn off any rule or group of rules, add a strict mode for filler words, and turn the badge off on sites you pick.

PRIVATE BY DESIGN
- Your text is checked on your device and never sent anywhere.
- No accounts, no analytics, no ads, no tracking.
- Installing asks for no access to any website. Site access is asked for only if you turn on "Check as I type", and you can take it back at any time.

FREE AND OPEN SOURCE
Tellbuster is MIT licensed. Every rule is plain, readable data, and anyone can suggest a new one on GitHub: https://github.com/aiprofitwire/tellbuster
