FinVerifyAI

FinVerifyAI is a real-time trust layer that verifies financial advice on social media so people don’t get misled while scrolling.

Inspiration

Last year, people lost billions of dollars after trusting financial advice they saw on social media not from bad intentions, but from missing context, hidden risks, and incomplete information.

Platforms like TikTok, YouTube, and Instagram have become financial classrooms. But there's a problem: most financial content is unverified, and users have no way to understand whether what they're hearing is realistic, risky, or incomplete before they act.

We asked ourselves: What if there was a way to add clarity at the exact moment someone encounters financial advice?

## What it does

FinVerifyAI is a Chrome extension and web platform that analyzes financial content and explains potential risks by comparing claims to publicly available, authoritative guidance.

Instead of telling users what to think, we help them understand why something may be risky in clear, human language.

  • One-click analysis on YouTube, TikTok, Instagram, and X
  • Step-by-step explanations highlighting assumptions, missing context, and risks
  • References to authoritative sources (SEC, FINRA, IRS)
  • Quality verification ensures every explanation is complete

## How we built it

At the core is Gemini 3 Flash, enabling us to reason over complex financial content.

Gemini 3 Integration:

  1. Multimodal Understanding Process text, audio, and visuals together
  2. Thinking Mode Transparent reasoning traces (up to 8,192 tokens) users can see
  3. Google Search Grounding Real-time verification against SEC, FINRA, IRS sources
  4. Self-Verification Loop Quality checks before showing results

Tech Stack:

  • Frontend: Next.js 15, React 19, Plasmo (Chrome extension)
  • Backend: Node.js, tRPC, Prisma
  • Database: PostgreSQL, Redis
  • Infrastructure: Vercel, Railway

## Challenges we ran into

  • Balancing depth vs. speed Implemented smart complexity detection to adjust thinking budgets dynamically
  • Avoiding false authority Designed to inform, not prescribe decisions
  • Cross-platform extraction Each social platform structures content differently
  • Quality at scale Built self-verification loops for consistency

## Accomplishments that we're proud of

  • Production-ready Chrome extension and web dashboard
  • 52 tests passing with full TypeScript coverage
  • First-to-market use of Gemini 3 thinking mode for financial reasoning

## What we learned

  • Transparency builds trust showing how AI reasons increases user confidence
  • Gemini 3's thinking mode is transformative for consumer AI
  • The gap between financial content creation and verification tools is enormous

## What's next for FinVerifyAI

  • Mobile apps (iOS/Android)
  • Live stream monitoring with real-time alerts
  • Creator credibility tracking
  • Multi-language support
