Inspiration

We saw how hard it is for everyday people to prepare a will—costly lawyers, endless forms, intimidating legal terms. Online services require a lot of typing, and have old interface. We thought, what if it felt like telling your story instead?


What it does

Will Maker AI turns estate planning into a guided conversation. Users talk about their life and wishes, and AI generates a legally formatted will with suggestions for executors, guardians, and charitable bequests.


Features

  • AI-powered voice-to-will conversion
  • State-compliant document generation with PDF export
  • Smart executor, guardian, and asset distribution suggestions
  • Charitable giving integration
  • Traditional form fallback for voice-free use
  • Multi-device support (responsive web app)

How We Built It

  • Frontend: React 18, TypeScript, Tailwind, Framer Motion
  • Conversational Audio AI: ElevenLabs for voice-to-text and speech synthesis
  • Infrastructure: Supabase for authentication, Database, storage, and real-time updates
  • AI Engine: OpenAI GPT-4 for document generation and smart suggestions
  • PDF Output: React-PDF for professional legal export
  • Payments: Stripe integration for premium AI features
  • Hosting/CI/CD: Netlify deployment and serverless architecture

Challenges We Ran Into

  • Data Extraction: Mapping free-form speech to structured legal data fields
  • Legal Compliance: Ensuring will templates adapt to different state laws
  • Form Testing: As the form is split in many steps, running testing took a lot of time to ensure the process worked as expected.
  • PDF Quality: Generating polished documents with dynamic layout, ready to be signed.

Accomplishments We're Proud Of

  • Reduced average will creation time from months to under 10 minutes
  • 80% AI prefilling success rate based on voice input (very conservative number)
  • Production-grade voice pipeline that feels like magic. No more boring fillings.

What We Learned

  • How to simplify a manual process (2-8 hours work) into 10 minutes.
  • How to design our app from scratch into a thick, big prompt that later is passed to Bolt.new. Less errors, more quality.
  • People forget/avoid boring tasks. This is a great business opportunity to use AI to shake the market.
  • We must have a clear structure of the whole form so that we can prefill it with a STT

What's Next

  • Launch on Product Hunt.
  • Add paid referrals to Attorneys.
  • Expand to multilingual voice support
  • Partner with legal nonprofits to serve underserved communities
  • Build APIs for financial institutions
