    HOW IT WORKS

    Write like you. Tellbuster points at the rest.

    1. Write as usual

      Draft your post, email or reply on LinkedIn, X, Gmail or any site. Nothing changes about how you type.

    2. See what stands out

      A small badge counts the phrases that read as AI. Red is a strong tell, amber a common one, gray a style note.

    3. Fix it your way

      Each card explains why readers notice the phrase and suggests a plainer version. You decide what to keep.

    A LINTER, NOT A DETECTOR

    It never says "this is AI."

    AI detectors guess, and they wrongly accuse real people. Tellbuster does something simpler and more honest: it shows the exact phrases readers link to machine writing and explains each one. People use these phrases too. You see the pattern and make the call.
