What types of content can I check?

You can check articles, blog posts, essays, emails, product descriptions, social media posts, and any other written text.

Is my content stored after I check it?

No. FixTools processes your text in the browser. Your content is never uploaded to a server or stored.

How do I interpret the AI score?

A high score (e.g., 80%+) suggests the text is likely AI-generated. A low score suggests it is likely human-written. Mid-range scores indicate mixed or ambiguous content.

Can AI-written content score as human?

Yes, if the text has been heavily edited or paraphrased. AI detectors look for statistical patterns that can be masked by significant rewriting.

Pro tips

Get better results with these expert suggestions:

Compare against known human writing

If you have access to prior work by the same author, run both samples and compare scores to see if there is a significant difference in AI probability.

Look for uniform sentence length

AI-generated text often has very consistent sentence structure. Scan for sections where every sentence follows the same rhythm.

Check specific sections, not just the whole doc

Some writers use AI for parts of a document. Test individual paragraphs or sections separately to identify which portions may be AI-generated.
