AI detectors compare statistical patterns in a text — sentence rhythm, vocabulary distribution, burstiness, and token perplexity — against baselines for human and AI writing. Passages that match AI baselines get flagged. Leap scores each sentence individually so you can see exactly which spans look like AI and which already read as human.Which AI models does Leap detect?
Leap identifies content from ChatGPT (GPT-3.5, GPT-4, GPT-4o, GPT-5), Claude (Sonnet, Opus, Haiku), Gemini (Pro, Ultra, Flash), Llama, Mistral, DeepSeek, Perplexity, and Grok. It's continuously tuned on fresh samples from new model releases so accuracy holds as models shift.Is Leap's AI detector free?
Yes. Detection is free with no word limit, no signup, and no usage quota. Only humanization counts against a paid plan — checking text is always free.How accurate is an AI detector?
In our internal testing Leap reliably distinguishes AI from human text on the major model families, with a low false-positive rate on natural human writing. Published accuracy numbers for AI detectors are benchmark-dependent — independent research (Stanford HAI, 2023; Penn Warren Center, 2024) has shown detector accuracy varies widely by input and that non-native English writing is at elevated risk of false positives, and OpenAI discontinued its own AI classifier in 2023 citing low accuracy. We surface sentence-level scores so you can judge the signal yourself rather than trust a single overall number. Short inputs (< 50 words) are harder for any detector.Is Quillbot's AI detector accurate?
Quillbot's AI detector has solid recall on obvious AI output (long templated paragraphs from ChatGPT or Claude) but returns only a single document-level score with limited per-sentence insight. It's a reasonable first pass; for mixed human + AI drafts or for understanding why something flagged, a detector that shows per-sentence scoring — like Leap — is more useful for actually fixing the writing.Is Turnitin's AI detector accurate?
Turnitin reports that its AI detection identifies AI-written text with high recall on ChatGPT output, but Turnitin hasn't published a full precision-and-recall breakdown and the tool is only available to institutional accounts, so independent benchmarks are scarce. Multiple universities have documented edge cases where Turnitin flagged human-authored writing — especially from non-native English speakers. Before submitting an assignment, running your draft through a transparent detector like Leap gives you a self-serve preview of the same kinds of signals Turnitin is checking.How accurate is Turnitin's AI detection?
Turnitin cites a low false-positive rate on its own test sets. Independent classroom reporting has been mixed — well-edited AI output slips through, and human writing with formal academic tone sometimes trips the detector. The honest answer: no AI detector is 100% accurate on every input, and institutional detectors have less transparency than consumer tools. Use the detector's flag as a prompt to look at the text carefully, not as a verdict on its own.Is Copyleaks' AI detector accurate?
Copyleaks' AI detector performs well on straightforward ChatGPT and Claude output and integrates with enterprise plagiarism workflows. Its weakness, like most detectors, is short inputs and stylistically mixed writing. Copyleaks is strong for bulk compliance use cases; for individual documents where you need to know which sentences are the problem, Leap's per-sentence view is easier to act on.What AI detector do colleges use?
The most common institutional detectors are Turnitin's AI detection (bundled with its plagiarism product, used by most US and UK universities), GPTZero (adopted by individual instructors), and Copyleaks (common in enterprise and research settings). Scribbr publishes a free detector aimed at students. Policies vary by institution — some require disclosure of AI use, some ban it outright in specific courses. Check your course syllabus or academic integrity policy before assuming.What AI detector do teachers use?
Individual teachers typically use whatever their institution provides (usually Turnitin's AI detection) and reach for consumer tools like GPTZero, Scribbr, or Leap for ad-hoc checks. Free sentence-level tools are especially useful in classroom conversations because they show the teacher and student which passages triggered the flag, not just a single verdict.Can I detect AI in essays, blog posts, or emails?
Yes. Leap works on any English prose — academic essays, blog posts, marketing copy, emails, product descriptions. Minimum input is 50 words; shorter inputs don't give detectors enough signal to distinguish human from AI reliably.Can an AI detector be wrong?
Yes — every AI detector has false positives and false negatives. Formal writing, short inputs, non-native English, and heavily edited AI drafts are the four categories where false positives climb. If a detector flags your writing and you know you wrote it, that's important context: no single tool is infallible. Use multiple detectors, look at which specific sentences triggered the flag, and if you still believe the flag is wrong, appeal it with evidence (drafts, version history) rather than trying to re-write to beat the detector.What should I do if my writing is flagged as AI?
First, verify with a second detector — no single tool is infallible and false positives happen. If the flag is correct, run your text through Leap's humanizer to rewrite it in a more natural style. If you wrote it yourself and it's still flagged, that's a false positive — consider varying sentence length, using more specific language, and removing any AI-style templated phrases.Should I trust a single AI detection score?
No. Treat any single detector's score as one input, not a verdict. Three disciplines help: (1) run the text through two or three detectors and compare, (2) look at per-sentence signals rather than the document-level number, and (3) consider the context — short inputs, non-native English, and highly formal writing are all known false-positive categories. Leap's sentence-level view is specifically built for this kind of careful judgment rather than binary yes/no.
