ChatGPT detector
Check for ChatGPT writing patterns.
Wondering whether a passage was written with ChatGPT? Run a text check, then look at the evidence behind the writing. AI Detect can help you review patterns associated with generated prose, but it cannot identify a ChatGPT account, recover prompts, or prove which model wrote a passage.
- Check a complete passage
- Review claims and citations
- No model attribution guarantee

Detection Score
Higher means a stronger AI writing signal. This is an estimate, not proof of authorship.
Readability
Rates how easy the text is to read on a scale from 0 to 100 — higher scores mean easier reading.
Grade Level
Indicates the U.S. school grade level needed to understand the text — higher education levels mean more complex reading.

How to review suspected ChatGPT text
- 01
Read before scanning
Note vague claims, unverified citations, and missing examples. These are editing questions, even when the author has never used AI.
- 02
Check the passage
Submit connected text to AI Detect. Avoid treating a single phrase such as “in conclusion” as evidence of AI use.
- 03
Ask for context
For a meaningful concern, ask how the writer developed the answer and which sources support it. Compare the explanation with drafts or notes.
Can a detector identify ChatGPT specifically?
A general AI text detector estimates whether language resembles generated writing. That does not establish the source model: outputs from different systems and human writing can share patterns. Treat a “ChatGPT detector” as a review aid, not access to OpenAI’s records.
Edited AI writing is harder to interpret
A draft may contain an original outline, AI-assisted phrasing, human revisions, and quoted sources. A single score cannot reconstruct that sequence. Decide what assistance is permitted in your context and ask for disclosure when it matters. Check factual accuracy separately from the detection score.
Frequently asked questions
Can AI Detect tell which ChatGPT version was used?
No. A score does not reliably identify a model version, prompt, account, or date of generation.
Does a low score mean no AI was used?
No. AI-assisted text may receive a result that looks human-written, and human work may be flagged. Scores cannot prove either conclusion.
Should I check a short message?
You can submit text within the tool’s limits, but very short messages contain little context. Review their meaning and provenance instead of relying on a score.
