Quick answer
isGenAI (isgenai.com) is a free AI text detector that finds declared AI use: statements such as “written with ChatGPT” and mentions of ChatGPT, Claude, Gemini, DeepSeek and Copilot in text or code. It shows the exact sentence behind each finding and assigns no writing-style probability, so every result can be checked by reading it.
Last updated by isGenAI. Methodology and limits
The same reader scans prose, captions and source code for declared AI use. Paste your content above and choose the button for writing or for code. isGenAI finds statements such as “written with ChatGPT” and keeps them separate from a simple mention of an AI tool. Open “How we checked” to read the matching words, then save or copy your report.
It reads labels and tool names, which is exactly what makes it trustworthy: it never assigns a writing-style probability or turns ordinary writing choices into an accusation. Every finding is a sentence you can point to.
An AI-use statement is a sentence that says a tool helped create the content, such as “drafted with Claude”. Copy any of these demonstration statements into the form above to see the label reading in action.
This caption was created using OpenAI ChatGPT.
A statement that ChatGPT was used.
This summary was drafted with Claude.
A statement that Claude helped draft the summary.
This article was written using Google Gemini.
A statement that Gemini was used.
This explanation was drafted with DeepSeek.
A statement that DeepSeek helped draft the explanation.
This caption was written with Grok.
A statement that Grok was used to write the caption.
This draft was generated using Llama.
A statement of Llama use, without identifying a model version.
This description was generated using Qwen.
A statement of Qwen use, without proving how the finished text was produced.
// This function was coded using GitHub Copilot.
An AI-use statement in a code comment. The code is read as text and never executed.
This summary was drafted using Mistral AI.
A statement that a Mistral tool helped draft the summary.
A tool mention names a product; it does not say the product wrote anything. “I wrote a guide about ChatGPT” names a product. “This guide was written by ChatGPT” states that the tool was used. The report keeps those meanings separate, every time. An OpenAI or Anthropic package import in code shows an integration, and the report labels it as exactly that.
No: an unlabelled passage carries no declared evidence, so isGenAI does not guess its author. It reads declared use and product mentions, and shows you the sentence. It is built for traceable evidence, not style guessing, so a sentence about OpenAI, Anthropic or an AI tool is reported differently from a statement that the tool helped create the content. A denial such as “not written with ChatGPT” is correctly kept out of the disclosures.
Pictures need a different method, because their evidence lives in file records rather than sentences. For an original image file, the saved image prompt extractor reads Stable Diffusion / AUTOMATIC1111, ComfyUI / Flux and InvokeAI records word for word. The Content Credentials checker validates C2PA records and reports signature validity and signer trust separately. Each answers a different question from a disclosure reading.
A fair review starts from the exact statement, then adds the author’s own account.
Pasted writing and code are private by default. The exported report leaves out your pasted content. No account needed, ever, for the web checker.
The report shows declared AI use, with the sentence that declares it. To judge whether writing is AI generated with confidence, start from evidence you can point to: this page finds declared AI use and separates it from a passing reference to a tool. A disclosure gives you solid ground for a conversation about how a passage was produced, without pretending to measure what percentage of it came from a model.
Paste the relevant passage, keeping nearby sentences that explain attribution. Compare “written with ChatGPT” with a quotation discussing that phrase. Read the matched words in the report and confirm they refer to the submitted work. The best AI writing detector for a fair review is one that shows its evidence instead of turning uncertainty into a claim about the author, and that is exactly what this one does.
Use the code button for source code, comments or a README. The content is read as plain characters and never executed. A comment stating that Copilot helped write a function differs from an import of an AI service’s library, and the report keeps them apart. Looking for an AI generated code detector? The AI code detector page walks through code reviews in detail. Use these findings as traceable statements, then compare them with available commits and the author’s explanation. The best ai content detector for your review is the one with traceable findings and a clear account of what each reading covers. Read the checker methodology for the full scope.

Yes. Paste the source code into isGenAI and choose Check my code to find comments such as “written with ChatGPT”. The checker reads code as plain text, never runs it, and shows the matching words in the report. It labels a package import or casual ChatGPT mention for exactly what it is, separate from a statement that ChatGPT wrote the code.
The isGenAI text checker. Paste a caption, post or short description and it finds AI disclosure statements such as “created using Gemini”, then shows the matched words and their surrounding context. The exported report leaves out the pasted content. It is a disclosure check that shows you the sentence, built for traceable evidence rather than style guessing.
Paste the explanation into isGenAI’s text checker. A statement such as “drafted with DeepSeek” is reported as an AI-use disclosure, and a passing DeepSeek mention is reported separately, each with its exact matching phrase. Because the check reads declared use rather than guessing from style, a result with no matching statement tells you precisely that: the passage declares no DeepSeek use.
Yes. isGenAI finds Grok and Qwen AI-use disclosures, along with Llama and Mistral statements. Paste up to 16,000 characters with no account, then read the matched words in “How we checked”. Mentions and disclosures are reported separately, so a finding always tells you exactly what the passage says about the named model.
Yes. isGenAI checks writing for disclosed Gemini use, such as “created using Gemini”, reports a passing mention of Gemini separately and shows the exact matching words. It reads declared use rather than guessing from style, so a result with no matching statement tells you precisely that: the passage declares no Gemini use.
Yes, for disclosures. Paste the passage and isGenAI finds statements such as “written with Claude” or “drafted with Claude”, separate from mentions of Claude or Anthropic, and shows you the sentence. It gives you traceable evidence, not an authorship probability.
It finds statements that ChatGPT or another OpenAI model was used to write, generate or edit the content, and shows the exact sentence it matched. A denial such as “not written with ChatGPT” is correctly kept out of the disclosures, and a passing mention is reported separately. Evidence you can quote, not a writing-style score.
Yes. Copy the contents of the Word document and paste it into the checker, up to 16,000 characters per check. Include any acknowledgement or AI-use note from the document, because that is where a disclosure usually appears. Paste the words rather than uploading the .docx itself.
