Which Tool Answers Which Question

The tools answer different questions, and mixing them up is a common source of confusion. Pick the one that matches what you actually need to know.

Your questionToolWhat it can’t tell you
Does this text read like AI writing?AI Text DetectorWho wrote it, or whether AI was used for research or editing
Was this text copied from somewhere?Plagiarism CheckerMatches in sources the provider can’t search, or whether text is AI-generated
Is this image AI-generated or face-edited?AI Image DetectorWhich generator made it; results weaken on compressed copies
Does this clip look AI-generated?AI Video DetectorWhether a face was swapped — it isn’t a deepfake detector
Are there spelling or grammar mistakes?Grammar CheckerEvery error — suggestions are automated and can be wrong

Before You Act on a Result

  • Treat every detection score as a probability. Detectors can flag human writing as AI and miss AI content.
  • Look for other evidence: drafts, version history, sources, the original file, or where a clip was first posted.
  • Talk to the person involved before drawing conclusions about their work.
  • Never base an academic, hiring or legal decision on a detector score alone.

Common AI Detection Scenarios

Academic Integrity

Students check their own work, and educators use detector results as one input alongside drafts and conversation.

Content Verification

Publishers and editors check articles, blog posts, and submissions for AI-generated content.

Quality Assurance

Content teams verify that outsourced or freelance writing meets authenticity standards.

Image Verification

Photographers and media professionals check images for signs of AI generation or face manipulation.

Video Authentication

Journalists and fact-checkers get an AI-generation signal on video clips as one input to their verification.

Self-Checking

Writers see how a detector reads their own work before sending it to clients or publishers, knowing any detector can be wrong.
