Lynote AI
Lynote AI runs a free online AI detector that scores pasted text or uploaded PDF, DOCX, and TXT files as AI-generated, mixed, or human-written. The checker returns three percentages and highlights likely AI sentences, so you can review flagged lines instead of trusting one number. Lynote built the detector to catch writing from ChatGPT, GPT-5, Gemini, Claude, LLaMA, Mistral, and paraphrased AI edits across 50+ languages.
Most AI detectors live on their own. Lynote folds detection into a study platform that shares one Study Credits pool with an AI humanizer, YouTube transcript and summary tools, document translation, flashcards, and AI note generation. Free registered users get 100 credits, Starter includes 3,000 per month, and Pro includes 10,000, which makes Lynote a better fit when detection is one step in a larger note-taking workflow rather than a one-off scan.
Students use Lynote to check essays and assignments, educators review drafts with sentence-level feedback, and marketers screen blog posts or client copy before publishing. Lynote reports 350,000+ detector scans per month, a 99% accuracy rate, and a 4.9 average rating from 12,589 users. The company states submitted text is processed securely and is not used to train its detection models.
