Find the AI tells in your draft.

Paste a post and see the patterns that make readers think a machine wrote it, each with the words that matched and the reason. No account, and your text is not saved.

Your text is sent to FeedSquad to be checked and is not saved. We log which patterns matched, never your words.

What this checker is, and is not

It reads your draft for known patterns. It does not judge who wrote it.

It finds patterns

Each result is a writing pattern from the AI Tells Index or FeedSquad’s anti-slop list, shown with the words that matched. You decide whether to change them.

It is not an AI detector

A tell is a probabilistic pattern, not proof of authorship. People write these patterns too, and a clean result does not show that a person wrote the text.

It does not check facts

A draft can pass every pattern and still be wrong. Check your claims separately.

How it works

FeedSquad runs these checks on every post it schedules.

  1. Rules you can read

    The patterns are public. The AI Tells Index gives each entry its sources, an example and a repair, and a result links to its Index page when it has one.

  2. Deterministic checks only

    This page runs the patterns a program can check for certain. Patterns that need a person or a model to judge are listed in the Index and not run here.

  3. Fix the cause, not the word

    Swapping one flagged phrase for a synonym leaves the habit in place. Read the reason and rewrite the sentence around what you mean.

Questions about the checker

No. It finds writing patterns that readers associate with AI text. A pattern is not proof of authorship: people write them too, and text from a model can avoid them.
Deterministic patterns from the AI Tells Index and FeedSquad’s anti-slop list: stock phrases, overused emojis, repeated sentence shapes and formatting habits. Each result names the pattern and shows the words that matched. The stock-phrase list is English only.
No. It is sent to our server to be checked and is not saved. We log which patterns matched, never the text itself.
Up to 20,000 characters in one check.
Yes. The same linter is a free MCP server at feedsquad.com/api/mcp-lint, with no account, so Claude, ChatGPT or another MCP client can check a draft before you see it.
Yes. FeedSquad runs these checks on every post it schedules, and nothing is published until you approve it.
