What this checker cannot do

It cannot detect AI
It finds phrases, not authors. Never use a result to accuse anyone.
It does not read context
"Robust" is filler in a launch and precise in an engineering review.
It is English only
Other languages pass with no marks, which says nothing about them.
It is not a quality score
Marks tell you where to look, not what to think.
It will not catch everything
New habits appear. The library is updated by hand; see the date above.

Catching these before you ever see them

Kairo Post drafts in each account's voice and checks every draft against that account's own list of phrases to avoid, before you approve it. See the AI writing feature, or browse more writing tools.

AI phrase checker questions

Testing just the opening line? Try the hook grader.

What does the AI phrase checker look for?

More than a hundred phrases and sentence patterns common in generated and padded writing, in six types: filler openers, inflated verbs, hype words, hedges, cliché closers and structural tics like "It's not X, it's Y".

Can this tool tell if a post was written by AI?

No. It finds patterns, not authors. People used these phrases long before language models, and a model can be told to avoid them. Treat a mark as a prompt to reread, never as proof.

Why do some words like delve get flagged?

Words such as delve, tapestry and underscore are rare in everyday writing but frequent in generated text, so readers notice them. They are not wrong; they are costly when unintended.

Is it bad to use one of these phrases?

Not by itself. One hedge can be exactly right. The problem is habit: several in one short post make it read like a template, and readers skim templates.

What does the marks per 100 words number mean?

Flagged phrases divided by words, times 100. Use it to compare two drafts of the same post. It is not a quality score or a probability.

Does the checker send my text anywhere?

No. The phrase list and the matching run in your browser, with no sign up and no cost. Nothing is uploaded, stored or sent to an AI model.

Can I add my own banned words?

Not here: this page uses a fixed library so it documents exactly what it checks. In Kairo Post, each account keeps its own list of phrases to avoid, and drafts are checked against it.
