01| Executive Summary

My Assets | My Will is a free, fully offline web application that helps the Indian family — designed first for senior citizens — turn a lifetime of scattered paperwork into one organised, private record, and then into a clear, properly structured Last Will. It captures every category of financial asset (the family’s “financial whereabouts”) and lets those assets flow directly into a Will with named beneficiaries and exact shares, ready to print or download as a Word document.

The entire application is delivered as a single HTML file that runs on the user’s own device with no internet connection, no servers and no accounts. It was conceptualised, designed and built by a practising Chartered Accountant using AI-assisted development through structured, staged prompting — demonstrating how deep domain expertise combined with AI can produce a complete, privacy-first product without a traditional development team.

02| The Problem We Are Addressing

This product did not begin in a boardroom. It began across the desk of a Chartered Accountant, in four ordinary conversations that left a lasting mark — each one the same story told differently.

Four stories that started it all

1. The son who lived oceans away. A senior client feared that if anything happened to him, his children in the USA would have no idea where his assets lay. He handed over bags stuffed with papers and asked for a simple checklist of his holdings.
2. The wardrobe full of a lifetime. An elderly client, asked for his details to draft a Will, pointed to a wardrobe of overflowing shelves — long-matured policies and financial papers buried and mixed with everything else.
3. A young family left to search. A 32-year-old engineer with a wife and two small children died in an accident abroad. Once again the grieving family handed over a bag of documents, and once again the work began by building a list out of chaos.
4. The bag that goes missing. It is not only illness or loss — the very same bag of documents surfaces during something as routine as shifting house, where papers are misplaced and never found when needed most.

Across all four stories the pattern is identical. People spend a lifetime building assets — bank accounts, deposits, lockers, investments, insurance, property, dues receivable, government schemes — yet the record lives in bags, wardrobes and scattered files that only they can decode. When that one person is gone, or cannot be reached in time, the family is left to play detective. The cost is not only money — forgotten policies, unclaimed deposits, frozen assets — but stress, delay and disputes at the worst possible moment, often across continents and language barriers.

03| The My Assets | My Will Solution

The application turns the bag of papers into one organised, private record — and then into a properly structured Will. It is built around three guided tabs and a set of capabilities designed so that age, language and technology are never a barrier.

04| Staged Prompting — The Development Methodology

The application was built using structured, staged prompting — a Chain-of-Thought approach where the product is broken into named stages, each building on the verified output of the one before. Every stage was reviewed by the CA acting as product owner and domain expert, and refined turn by turn. Every change was deliberately surgical and validated before delivery.

1 Foundation — define the family and the structure

Sample prompt: “Build a single-file offline HTML app for Indian senior citizens to record assets and a Will. Three tabs: Profile & Family, Financial Whereabouts, Will. Store state in localStorage, no backend, runs on file:// .”

■ Output: App shell, three-tab layout, profile and family capture, local persistence.

2 Financial Whereabouts — the 12 asset categories

Sample prompt: “Add 12 categories from About-Me to Anything-Else with entry forms, count badges and a two-column sidebar. Scope each form so shared input IDs never cross-contaminate.”

■ Output: Complete Financial Whereabouts tab across all categories.

3 The Will engine — assets to beneficiaries

Sample prompt: “Map each asset by category:id to named beneficiaries with shares summing to 100%, or to a residual clause. Generate a Will body to the Indian Succession Act, 1925, with executor and witnesses.”

■ Output: Asset-to-beneficiary mapping, executor and witness blocks, Will preview.

4 Multilingual — speak the family’s language

Sample prompt: “Add an 11-language i18n layer driven by data-i18n attributes, with a language selector on the landing page and inside the app, kept in sync.”

■ Output: Eleven Indian languages with a live translation layer.

5 Document Fetch — read the bag of papers

Sample prompt: “Add on-device PDF parsing and image OCR to auto-fill entries from PAN, Aadhaar, statements and policies. Use multi-signal scoring and validate Aadhaar with the Verhoeff checksum.”

■ Output: Self-contained document-fetch module with OCR fallback and validation.

6 Export & polish — a Will ready to sign

Sample prompt: “Export the Will as a formatted Word document, refine the landing page and sidebars, and harden auto-save with quota handling.”

■ Output: Word export, refined landing page, robust local persistence.

05| Technology & AI-Assisted Development

Unlike a typical cloud product, this application has no backend, no build tools and no accounts. The single-file constraint is intentional and non-negotiable: the deliverable is one HTML file a family can keep, copy and open forever, with no dependency on any company remaining in business.

Note on libraries: the three helper libraries (docx.js, PDF.js, Tesseract.js) are loaded from a CDN on first use and then cached. The core application — recording assets, drafting the Will and saving locally — works entirely offline without them.

06| Data Architecture

The application holds a single structured state object in the browser, saved under one local key. There is no database and no transmission — the entire record lives and stays on the device.

07| Privacy, Offline-First & Trust

For a document as sensitive as a record of one’s entire estate, privacy is not a feature — it is the foundation. The application is built so that the family never has to trust a third party with their most confidential information.

08| Key Learnings from the Project

1. Domain expertise + AI is a powerful combination. Real advisory cases — the four stories — made every requirement precise. The professional carried the domain and the law; the AI carried the code.
2. Staged prompting is software architecture. Breaking the build into named stages (Foundation → Categories → Will → Languages → Document Fetch → Export) mirrors traditional architecture. Each prompt was a design decision, not just a request.
3. Surgical changes protect a working product. A standing “do not change anything else” discipline, with validation before every delivery, kept a large single file stable through many stages.
4. Specificity is everything. Exact field names, key formats, category codes and the relevant law in each prompt dramatically improved output quality and cut iteration.
5. Privacy-first can be simple. An offline single file proved that protecting sensitive family data does not require a complex cloud stack — sometimes the most trustworthy architecture is the smallest one.
6. AI-assisted development is ready for real, sensitive work.This is not a toy. It produces a legally-structured Will and a confidential asset record for real families.

09| Conclusion & Future Roadmap

My Assets | My Will is a genuine contribution to the Indian family. The need is real and immediate — every senior citizen with scattered records, every family that has had to play detective after a loss, every household that has misplaced the “bag of documents” during a move. By bringing assets and intentions together, in the family’s own language, on their own device, the application protects both the person and those they leave behind — so that a lifetime of effort reaches the right hands, smoothly and with dignity.
