AI or Not

AI or Not is an AI content detector that helps you tell whether text, images, video, voice, or music was created by a human or generated by AI — before you share, submit, or publish it. Paste your content or upload a file, and the detector returns a clear result in just a few seconds. For text, AI or Not analyzes writing for the patterns that large language models leave behind and flags content generated by popular models including ChatGPT, Claude, Gemini, and Copilot. Instead of handing you a single number, it shows its work: you get an overall AI-probability score plus a sentence-by-sentence breakdown that highlights exactly which lines read as machine-written. Each result is color-coded — red, amber, or green — so you can spot AI passages at a glance, and it catches mixed content where only some sentences are AI rather than treating writing as all-or-nothing. Every verdict comes with the signals behind it, such as flat rhythm, give-away transitions, and unusually even pacing, so the result is explainable rather than a black box. Beyond text, AI or Not includes dedicated detectors for images, video, voice, and music, so you can check almost any kind of content from one place. It works across multiple languages, including English and Chinese, and is tuned to keep pace as new AI models appear. AI or Not is built for anyone who needs to trust what they read, send, or publish: - Students can check essays and assignments for AI writing signals before turning them in, and see exactly which lines got flagged. - Researchers and professionals can screen papers, reports, and proposals for AI-sounding filler and template phrasing before they reach reviewers, clients, or stakeholders. - Writers, editors, and publishers can verify drafts so articles read naturally and keep their byline credible. - Teams and platforms can review user-submitted or outsourced content to confirm it was genuinely created by a person. The detector is designed to protect real writers. It leans toward fewer false alarms on genuine human work and treats every score as a strong signal to weigh with context — never a final ruling. AI or Not does not train its own models on your content, and results are yours to verify or share. AI or Not is free to start, with paid plans that unlock higher limits for heavier use. Paste up to a generous free character limit per check, get results in seconds, and create a free account to raise your daily limits and keep a history of every check you run. Detect AI in text, images, audio, and video — in seconds, before you share.
