Why use aitextdetectly
Sentence-level highlights
Checked sentences are marked human-written, AI-refined, or AI-generated, so you can see where in the text the signal sits.
Admits uncertainty
When the whole text and its passages disagree sharply, the verdict says Inconclusive instead of picking a side.
Your text isn't kept
It goes to the detection model for that one scan. We keep no copy and don't train on it.
Free to start
3 scans a day of up to 5,000 characters on a free account. No card needed.
How it works
Three steps to a closer look
Paste your text
Type it in, paste it, or upload a .txt or .md file.
The detector reads it
It scores the whole text, each passage, and the sentences inside them.
Read the result
You get AI, mixed, and human percentages and the indicators behind them. Split evidence gets an Inconclusive verdict.

FAQ
Questions, answered
Everything you need to know about aitextdetectly.xyz.
Is the AI detector free?
Yes. Create a free account to get 3 free scans a day of up to 5,000 characters each. No card required. Paid plans raise the limits.
How accurate is the AI detector?
Accuracy varies with the writing and the model that produced it. Scores are model estimates, not measured probabilities of authorship. We show an inconclusive verdict when the available signals do not support a clear result.
Can an AI detector be wrong?
Yes. No AI detector is 100% accurate. Short passages, heavily edited drafts, formulaic writing, and writing by non-native English speakers can all be misread. Treat the score as one signal alongside drafts, version history, and a conversation with the writer, never as the only evidence of misconduct.
Which AI models can it detect?
It is built to pick up writing from ChatGPT, Claude, Gemini, and other large language models, including text that mixes human and AI writing.
Is my text stored or shared?
We don't store your text, sell it, or use it to train models. To analyze it, the text is sent to our detection provider for that one request, and we keep no copy afterwards. The privacy policy has the details.
Can I upload a file instead of pasting text?
Yes. Use the Upload File tab to drop in a .txt or .md file. Free allows 3 scans per day of up to 5,000 characters. Plus raises that to 1,000,000 words a month at up to 50,000 characters per scan, and Pro to 4,000,000 words at up to 100,000 characters, with batch upload.
How does pricing compare to Originality, Winston, and Pangram?
Plus is $12 a month, under Originality ($14.95), Winston ($18), and Pangram ($20). Pro is $15 and includes 4,000,000 words a month, API access, batch upload, and 5 seats; Pangram Pro is $65 and Originality team plans start at $179. Competitor prices are their public list prices as of September 2026.
Do unused scans roll over?
No. Plus resets to 1,000,000 words and Pro to 4,000,000 words at the start of each month, and unused words don't carry over. Paid plans also include up to 2,000 (Plus) or 2,500 (Pro) scans a month. Free resets to 3 scans every day. You can cancel any time.
