## Context

**Copilot Money** — Personal finance app for spending, budgets, investments, and net worth. It currently costs $13/mo.

A beautiful spending dashboard can be vibecoded, but Copilot's bank/investment sync, categorization, native Apple apps, and data-security posture are the product.

This brief describes a focused, single-operator replacement for the part of Copilot Money that is genuinely reproducible. It is deliberately narrower than the product it replaces, and it says so in writing. Build the useful core; do not pretend to have rebuilt the rest.

## What you are building

Import bank/CSV data, categorize transactions with rules/LLM, show budgets, investments, and net-worth charts.

- Build a focused single-user workflow with real persistence, search, and export.
- A responsive interface with real empty, loading, success, and error states.

## Requirements

### Functional

- Secure storage.
- MacOS/iOS/web app.
- Categorization rules.
- Charts.

### Data and integrations

- Plaid/bank API or CSV import.

Each of these needs a real account, credential, or quota. Set them up before writing feature code.

### Non-functional

- Accessibility: semantic markup, labelled controls, visible focus, and reduced-motion support.
- Security: server-side secrets, validated input, and no credentials in the client bundle.
- Reliability: retries with backoff on external calls, and a clear failure state when a provider is down.
- Portability: the operator can export their data and leave without losing it.

## Implementation brief

Build me a personal finance dashboard to replace Copilot Money. Requirements:

- Local web app: Node + Express + better-sqlite3, charts with Chart.js, no
  build step.
- No bank APIs: I drop CSV exports from my banks into imports/, a chokidar
  watcher ingests new files using per-bank column maps in mappings.json,
  and rows dedupe on a date+amount+description hash.
- Categorization: ordered regex rules in rules.json run first; unmatched
  transactions land in a review page where one click assigns a category and
  offers to save the pattern as a new rule. Optional LLM fallback, key in
  .env.
- Dashboard: current month spend by category against per-category budgets,
  a 12-month trend line, and top merchants.
- Recurring detection: the same merchant at roughly monthly intervals gets
  flagged as a subscription and listed with its annual cost. This list
  alone tends to pay for the build.
- Accounts and net worth: monthly balance snapshots per account, plotted
  over time.
- Everything local in one SQLite file, localhost only, no telemetry; note
  in the README that the optional LLM call sends transaction text out, skip
  it if that bothers me.
- Out of scope: automatic bank sync (Plaid needs approval and per-connection
  fees) and investment tracking; CSV import is the honest personal version.
- README: how to add a new bank's CSV mapping.

## Delivery standard

- Inspect the repository first, then write a short implementation plan before writing code.
- Deliver the smallest complete end-to-end workflow first; every primary control must work against persisted data.
- Use real validation and storage; never substitute fake dashboards, decorative controls, hard-coded success states, or mock integrations.
- Include responsive layouts plus genuine empty, loading, success, validation, and failure states.
- Keep secrets server-side in environment variables, provide .env.example, and never commit credentials or user data.
- Add structured logs around every external call and return actionable errors without leaking sensitive details.
- Write unit tests for the core logic and one automated test of the main user journey.
- Finish with a README covering setup, architecture, data location, backups, tests, deployment, and known limitations.

## Acceptance criteria

- [ ] A clean install starts the app using only the README and .env.example.
- [ ] The primary journey works from first visit through saved result, reload, edit, export, and deletion where applicable.
- [ ] Invalid input, missing configuration, provider failure, and an empty database each have a usable state.
- [ ] The interface works at 390px and 1440px, is keyboard navigable, and shows visible focus on every control.
- [ ] Tests, type checking, linting, and a production build all pass with no ignored failures.
- [ ] No part of the interface implies a live integration, security guarantee, or scale capability that was not actually built and verified.

## Non-goals

Do not build these, and do not claim to have replaced them:

- Bank sync.
- IOS/Mac polish.
- Transaction enrichment.
- Investment tracking.
- Connectors, OAuth flows, and vendor API changes require constant upkeep.
- The last 20 percent is sync, migration fidelity, speed, and edge cases.

## What you still own after launch

- Secure credentials, rotate secrets, and handle provider rate limits.
- Run migrations, backups, restores, and dependency updates.
- Test the critical journey after every model, API, or hosting change.
- Monitor failures and fix the edge cases a first prompt will miss.
- Maintain every third-party integration as APIs and OAuth rules change.

## Risk

**High consequence.** Use this as a prototype or personal aid. Keep a qualified human and an established provider in the loop for consequential decisions.

Editorial confidence in this assessment: medium. No independent one-shot implementation is linked yet.

## Prior art

Working open-source software you can read, fork, or borrow from before starting:

- [Actual Budget](https://github.com/actualbudget/actual) — Open-source budgeting app; good starting point for a DIY personal finance workflow
