官方常见问题
- How does an AI content detector work?
- 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 ris
- 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 sp
