The differentiator

Most tools bolt a chatbot onto a form. myAevum treats AI as the primary interface — a named assistant, Aevum, that guides owners to complete their estate record, then gently walks grieving family members through it when they need it most.


What I built

Production application, end to end

A live app on a Cloudflare Workers API backend serving authenticated estate vaults — full CRUD across nine estate categories spanning financial accounts, insurance, legal documents, physical valuables, dependents, pets, and more.

An AI assistant grounded in real data

Aevum is grounded in each user’s actual vault contents: vault data is injected as structured context on every query, with hard guardrails against fabricating financial or legal details. It runs in two modes — a proactive coach for vault owners, and a calm, emotionally calibrated guide for family members at the handoff moment.

Proactive gap detection

A system that identifies missing or incomplete estate information and surfaces targeted prompts to fill it — turning a daunting, open-ended task into a guided one.

Document extraction

AI-powered extraction of structured fields — account numbers, beneficiaries, policy details — directly from uploaded documents.

Secure family handoff

A handoff access flow with tiered permissions enforced at the API layer, time-expiring invite tokens, and access logging — the moment the whole product exists to serve.
