Digital Will Assistant

AI finds your forgotten bank, crypto and insurance accounts, alerts trusted family if you go silent, and backs it all with a witnessed digital will, so your digital life never disappears with you.

Inspiration

Life is unpredictable. Someone can pass away suddenly, have an accident, or be unconscious for months. When that happens, their family often has no idea which banks they use, where their crypto wallet is, what insurance they have, or which subscriptions are still charging. A paper will doesn't cover any of that.

I wanted to answer one question: if something happens to me, what happens to my digital life? Right now the answer is usually "it disappears." I built Digital Will Assistant to change that.

What it does

Digital Will Assistant is a safe place to prepare your digital life for your family.

  • Vault: record where each account, wallet, policy, subscription and document is, who the nominee is, and who should handle it. It stores where a password is kept, never the password itself.
  • AI asset discovery: paste emails, texts, statements or file names, and it finds accounts you forgot. It also flags what's missing, like a bank account with no nominee or a crypto wallet with no recovery plan.
  • Safety trigger: if you stop responding for a set number of days, it checks on you first. Only if you don't answer are your trusted contacts notified. They must confirm before anything opens, and each person sees only what you allowed.
  • Add Family: invite someone with a personal short link. When they join, they choose how they're related to you (father, mother, sister, uncle and so on), and you get a notification.
  • Digital will: write your will with basic formatting, translate the built-in clauses, dictate by voice with language detection, sign digitally, and name two witnesses. Once signed, the text is locked, so any later change shows.
  • Legacy report: turns everything in your vault into plain language your family can follow.

The app also has a readiness score and works in English, Hindi, Tamil, Telugu, Spanish and French.

How I built it

I built it as a single web app using HTML, CSS and JavaScript, with no backend. Everything stays in the browser, so nothing a user enters is sent anywhere. The asset scanner runs on the device using pattern matching. The signature uses Canvas, the will's tamper-proof fingerprint uses the Web Crypto API, and voice uses the browser's recording and speech tools. I designed it with a soft light palette, rich sans-serif fonts, and a translucent orange text highlight.

Challenges I ran into

  • Passwords: a vault full of passwords would be a single point of failure, so I decided to store only where they're kept.
  • Timing the alert: telling family too early is as bad as too late, so the trigger checks on the user first and needs several contacts to confirm.
  • Translation without a service: I built a library of will clauses in six languages and made the app clear about what it translated and what it left as written.
  • The law: electronic wills aren't valid everywhere, so the app says so clearly and treats the will as a record of wishes for a lawyer to review.
  • Microphone limits: recording isn't always available, so I added audio upload and a typed transcript.

Accomplishments that I'm proud of

  • A complete flow in one file: sign-up, finding forgotten accounts, family invites, the safety trigger, and a signed and witnessed will.
  • A trigger simulator that lets anyone watch the whole emergency sequence in seconds.
  • A scanner that finds forgotten accounts without any data leaving the device.
  • An invite flow where the invited person says how they're related to you.

What I learned

  • The hard part of digital legacy is trust: who is told, when, and what they can see.
  • People forget accounts more than they hide them, so discovery helps more than an empty form.
  • Keeping data on the device makes the product easier to trust.
  • Building for several languages from the start changes every screen.

What's next for Digital Will Assistant

  • End-to-end encryption with a real backend.
  • A real language model for discovery, summaries and will translation.
  • Real email and SMS alerts, and a server-side scheduler for the trigger.
  • Witnesses signing on their own devices with verified identity.
  • Lawyer-reviewed will templates for different countries.
  • Links to password managers and platform memorial settings.
