Build a detection tool that identifies AI-generated text with measurable accuracy, then find which specific customer segment has enough pain and budget to pay for it.

The pain

Teachers catch plagiarism using ChatGPT. Publishers worry about content farms. Hiring managers question resume authenticity. But most people don't actually pay for detection, they use free tools or accept the risk. The pain exists but hasn't converted to revenue at scale.

The gap

Detection tools exist (Turnitin, GPTZero, Originality.ai) but they're unreliable. AI models improve faster than detectors can adapt. No tool achieves >90% accuracy consistently. The technical problem is real, but the business problem is unclear: who will pay enough to sustain a company?

Build angle

Start by picking one vertical with acute, measurable pain and budget: either enterprise content verification (news organizations, academic publishers) or B2B2C (integrate into LMS platforms like Canvas). Build detection that works specifically for that use case rather than trying to solve detection universally. Charge per API call or per document checked. Validate that customers renew.

Strengths

  • Real technical problem with no perfect solution
  • Multiple potential customer segments (education, publishing, hiring, content platforms)
  • Growing urgency as AI-generated content increases
  • Defensible if you build proprietary detection models

Risks

  • Detection accuracy degrades as AI models improve, you're in an arms race
  • Free alternatives (Turnitin, built-in LMS tools) reduce willingness to pay
  • No clear winner in detection space despite years of attempts
  • Customers may not renew if false positive/negative rates are high
  • Regulatory uncertainty: detection tools may become commoditized or obsolete
  • Hard to build moat, detection is pattern-matching, not defensible IP
