Inspiration

Misinformation in health and wellness spaces spreads rapidly, with unverified claims about supplements, diets, and treatments often lacking scientific backing. LintifAI addresses this by bridging the gap between casual browsing and peer-reviewed research – acting as a real-time "trust assistant" for consumers.

What It Does

  1. Chrome Extension: Users highlight text on any webpage and trigger LintifAI's analysis.
  2. AI Fact-Checking:
    • Cross-references claims with 50M+ research papers (PubMed, Google Scholar) and vetted sources (WHO, CDC).
    • Generates a Truth Score (1-100) based on consensus in credible studies.
    • Flags conflicts between claims and established science (e.g., "No studies support lemon juice curing cancer").

How We Built It

  • Frontend: Chrome Extension (React) with highlighting overlay and score badges.
  • Backend: Hardwired and engineered specific prompts using the OpenAI API with web search capabilities.

Challenges

  • Latency: Real-time analysis required optimizing database queries and caching frequently checked claims.
  • Bias Mitigation: Avoiding over-reliance on single studies by emphasizing meta-analyses.
  • Ambiguity: Handling statements like "may boost immunity" that lack measurable parameters.

Accomplishments That We're Proud Of

  • Successfully built a functional proof-of-concept MVP that effectively tackles the core problem of health misinformation online.

What We Learned

  • AI is a powerful tool and presents a viable approach to effectively combat the spread of misinformation, particularly in the health and wellness domain.

What's Next & Business Model

  • Pilot program: Benchmark user engagement and validate MVP with real users.
  • Post-MVP: Build a database of trusted/untrusted health websites for reference.
  • Full-page analysis: Enable automatic verification of all claims on a webpage, not just selected snippets.
  • Autonomous workflow: Streamline user experience so fact-checking happens seamlessly, without extra steps.

These steps ensure LintifAI evolves based on real user feedback and delivers a more robust, user-friendly solution.

Monetization Strategy: As we grow our user base and better understand our target audience, we'll be able to identify a pricing strategy that feels natural and non-intrusive—ensuring that access to trustworthy health information remains accessible while supporting ongoing development.

  • Subscription Model:
    • Free tier: Analyze 5 text snippets/day with basic source links.
    • Pro tier: Unlocks features like full-page analysis, detailed study summaries, and trend alerts (e.g., "This claim was debunked in 2023"). Pricing will be refined based on user feedback to avoid creating barriers or nuisances for our core users.
