Can AI build a net worth tracker app like Empower?

Build a personal net worth tracker web app to replace Empower's dashboard for my own use, with manually entered balances instead of live bank syncing.

Tech rules:
- Plain HTML, CSS, and vanilla JavaScript in one file. No framework, build step, account, or server.
- Store all data in localStorage under one key, with a version number.

Data model:
- Account: id, name, type (bank, brokerage, retirement, crypto, illiquid asset, debt), currency, balanceHistory [{date, value}].
- NetWorthSnapshot: date, totalAssets, totalDebts, netWorth (computed).

Features:
- Add accounts by type: bank, brokerage, retirement, crypto wallet, illiquid asset (house, car, private stake), or debt (credit card, mortgage, loan).
- Enter a balance for each account, with the date of that balance, building a history per account over time.
- Debt accounts subtract from the net worth total automatically; the app shows them clearly as negative contributions, not confused with assets.
- A historical net worth trend chart plotting the total over months and years, built from each account's balance history.
- Currency field per account, with a simple manual conversion rate you can update, so foreign-currency accounts roll into one net worth total.
- A monthly reminder prompt (shown in-app, not a push notification) to update balances, since this app has no automatic syncing.

Edge cases the build must handle correctly:
1. Manually valuing illiquid assets like a house, car, or private business stake is a simple number entry with a date, clearly labeled as a manual estimate, not a live value.
2. Crypto wallet balances are tracked in their own account type, separate from bank and brokerage balances, and convert to your base currency using the manual rate you enter.
3. Currency conversion for foreign-currency accounts applies consistently across the trend chart, not just the current total.
4. The historical net worth trend chart correctly reflects gaps: if an account isn't updated for a month, the chart carries forward its last known value rather than treating it as zero.
5. Debt accounts (credit cards, mortgages, loans) are shown and totaled as negative values, never accidentally added as positive balances.
6. An account that stops being updated (a closed institution link, in Empower's case, or simply one you stop tracking) can be archived without deleting its historical contribution to past snapshots.
7. Adding a balance entry for a past date recalculates the trend chart at the correct point in the timeline, not just appended at the end.

Backup:
- One-click "Export JSON" and "Export CSV" of all accounts and balance history.
- "Import JSON" restores after confirmation.
- An importer that reads an Empower CSV export (transactions or holdings) and lets you map it into a starting account balance.

Layout:
- Mobile-first, readable at 375px wide, a clear net worth number at the top of the screen.

Exclusions:
- No publishing, App Store submission, accounts, live bank-account syncing, payments, or social features. No automated login scraping of any financial institution.

Write a short README explaining where data is stored, how to export and restore it, and how often you should manually update balances.

Keep it under 600 lines. This is a personal tool, not a product.

What is the short answer?

Yes, but. Empower’s Personal Dashboard is free, with no feature paywall on the net worth tracker, budgeting tools, or retirement planner. AI can build a manual-entry net worth tracker with a trend chart in about a day.

The “but” is that Empower’s dashboard is free specifically because it doubles as a lead-generation funnel for its 0.89%+ AUM advisory arm. Multiple reviews report that linking accounts with meaningful balances triggers real sales calls from an advisor [VERIFY]. If you just want a net worth number and don’t want that pipeline, building your own is worth it, not for the money, since Empower costs nothing, but for the privacy and the lack of a sales funnel behind it.

Option	Best for	Upfront cost	Ongoing cost	Main limitation
Build a rough prototype	Someone who wants a private net worth number without linking accounts	$0 and 3–4 hours	$0	Manual balance entry only, no auto-sync
Build a daily-use personal version	Someone who wants a full trend chart, illiquid assets, and multi-currency support	$0 and 8–10 hours	$0	Still manual entry; no live bank feeds
Keep paying for Empower’s advisory upsell (the dashboard itself is free)	Someone who wants automatic syncing across 14,000+ institutions	$0	$0, unless you cross into advisory AUM fees	Reported advisor sales calls after linking meaningful balances [VERIFY]

The ready-to-paste starter prompt at the end of this page builds the daily-use version.

What should the first version include?

The first version needs to make manual entry fast enough that you’ll actually keep doing it.

• Manual entry for bank, investment, and debt balances
• Debt shown as negative values
• A historical trend chart
• Illiquid asset entries for things like a house or car
• Crypto tracked separately from bank and brokerage accounts
• Deliberate exclusion: no live bank-account syncing. A personal build should never scrape your bank login.

What can AI build reliably?

ChatGPT and Claude build the account model, manual balance entry, and a trend chart reliably. This is arithmetic and a chart, not real-time financial infrastructure.

Concrete things AI gets right:

• A net worth total that correctly nets assets against debts
• A trend chart that carries forward the last known balance instead of treating a gap as zero
• Separate tracking for crypto wallets versus bank and brokerage accounts
• Currency conversion applied consistently across the chart, not just the current total

Where will AI need human help?

The biggest gap isn’t a coding problem, it’s a habit problem. Manual balance entry becomes the real weekly or monthly workflow, and that’s the habit most DIY net worth trackers get abandoned over within a few months. No amount of good code fixes this; you have to actually commit to updating balances, or the trend chart goes stale and the tool stops being useful.

Valuing illiquid assets needs your judgment, not the app’s. Home equity, a car, or a private business stake needs an outside estimate, like a Zillow value or a recent appraisal, that the app itself can’t generate. Update these less often than liquid accounts, since they don’t change daily, but don’t let them go stale for years either.

The decision only you can make is whether live bank syncing is worth the security trade-off. There’s no safe way to auto-pull live bank and investment balances without a paid account-aggregation API like Plaid, since rolling your own bank-login scraper is a real security liability. Manual entry is the safer default for a personal build, even though it’s more work.

Privacy is the whole point of this build for many people. Keep balances local with no account and no analytics, since the reason to build this in the first place is often to get away from an app whose business model depends on knowing your finances.

Can I get my data out of Empower?

Yes, mostly. Web app: Overview > Transactions, then the CSV export icon next to the search field; investment holdings export the same way from the Investment tab. No paid plan is required for any export.

The export trap: net worth history itself exports only as a PDF snapshot on iOS, not as a structured CSV you can re-chart yourself; only transactions and holdings export as CSV [VERIFY]. The CSV export also silently matches whatever date-range filter is currently applied, and it defaults to a 90-day view, so leaving that in place gives you a truncated export with no warning [VERIFY].

The practical path: before exporting, manually set the date filter to “All Time,” then export transactions and holdings as CSV. For your actual net worth history, you’ll likely need to manually re-enter starting balances for each account rather than importing a clean historical trend, since Empower doesn’t offer one as structured data.

How long will it take and what will it cost?

Rough prototype: 3–4 hours and $0. Manual account entry, a basic net worth total, and debt handling.

Dependable daily-use version: 8–10 hours, including the trend chart, illiquid assets, crypto tracking, and currency conversion. Build it on a free AI plan.

There’s no break-even math here either, since Empower’s dashboard costs nothing. What you’re trading is convenience, automatic syncing across thousands of institutions, for privacy and freedom from a sales funnel.

These are estimates from reviewing the feature set, not measurements from a completed build.

Which AI tool or approach should I use?

Claude or ChatGPT on a free plan handles the account model, totals, and chart comfortably.

Cursor isn’t necessary for a build this size.

Lovable isn’t a good fit either. Adding a hosted database for account syncing reintroduces the same kind of third-party financial data handling this build is meant to avoid, without the benefit of Empower’s established security infrastructure.

What will I need to maintain?

The habit matters more than the code here.

Recurring work:

• Manually update account balances on a schedule you’ll actually stick to, weekly or monthly
• Export a JSON or CSV backup every few months
• Refresh illiquid asset valuations (home equity, vehicle) a few times a year, not constantly

Should I build it, buy it, or reduce scope?

Build it if you want a private net worth number and don’t need automatic bank syncing, and you’re specifically trying to avoid being a lead for Empower’s advisory arm.

Buy it, or rather, keep using Empower, if automatic syncing across thousands of institutions matters more to you than the reported sales-call risk, and you’re comfortable declining any advisor outreach.

Reduce scope if you just want a single current number, not a trend over time. A one-time spreadsheet calculation covers that without building or maintaining anything.

Recommendation: build it if privacy from Empower’s advisory funnel is your main motivation, since the dashboard itself is free and the only thing you’re really giving up is auto-sync. Keep Empower if the convenience of linking 14,000+ institutions outweighs the sales-call risk for you. If you’re also budgeting monthly cash flow or tracking debt paydown separately, see the YNAB-style budget build and the Tally-style debt tracker build.

What if I wanted to ship this to other people?

Shipping a net worth tracker to other people means either building or licensing a secure account-aggregation integration like Plaid, real financial data security and compliance obligations, and competing with a free, well-resourced incumbent. It’s a much bigger project than a personal manual-entry tracker, with real liability if financial data is mishandled.

Starter build specification

• User: You, for your own use, tracking your own net worth privately.
• Problem: Wanting a private net worth number without Empower’s account-linking-to-advisor-outreach pipeline.
• Core workflow: Add accounts by type, enter balances on a regular schedule, review the trend chart, occasionally update illiquid asset valuations.
• Required features: Manual balance entry by account type, debt as negative values, historical trend chart, illiquid asset tracking, crypto tracked separately, currency conversion.
• Deliberate exclusions: No live bank-account syncing, no accounts, no advisory features, no social features.
• Data ownership: Stored in localStorage. Exported as JSON and CSV. Imported from JSON or a mapped Empower CSV.
• Definition of done: A debt account correctly reduces the net worth total, the trend chart carries forward a stale account’s last value instead of showing zero, and a foreign-currency account converts consistently across the chart.
