What it marks

AI writes the way it always does unless someone gives it rules, and almost nobody types out a long list. Stet starts with the list and changes it for each kind of writing.

  • Em dashes and semicolons
  • Lists of exactly three things
  • The “not this, but that” format
  • Sentences that start with But or And
  • Colons in the middle of a sentence
  • Filler phrases and buzzwords
  • Sentences that run too long

AI drafts are next

Stet will write a draft, then check and rewrite it up to three times. We're opening that in small groups, starting with this list.

We only use your email to tell you about Stet.

Questions

Where does my writing go?

The checker runs in your browser, so your text never reaches us. If you join the waitlist, we keep your email address.

Can I use it for class?

Yes, within your course's AI policy. We don't build features for beating AI detectors, and the checker isn't one.

What does it check?

Rules that code can verify, like punctuation, list length, sentence length and banned phrases. It can miss things, so read your draft before you send it.

When do AI drafts open?

We're opening them in small groups, starting with the waitlist. The checker stays free either way.
