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
