Can AI replace Lunch Money?
KINDA · weekend projectThe core loop is buildable, but a dependable replacement becomes a real weekend or multi-day project. For Lunch Money, import transactions and maintain a transparent personal ledger with rules and reports. The hard boundary is bank sync, multi-currency support, api, community, and hosted convenience, plus financial integrations, compliance, and trust.
Build a personal replacement for Lunch Money in an empty repository. Use Next.js 15, TypeScript, SQLite, Drizzle ORM, and local-first encryption; do not offer alternative stacks. The core loop is: import transactions, categorize them with transparent rules, reconcile balances, and maintain a personal ledger with clean exported reports without moving money. Make the first run work locally with one documented command. Store all user data locally by default and make export straightforward. Put secrets in .env, ship .env.example, and never commit credentials. Support CSV and OFX import with saved column mappings and duplicate detection. Implement accounts, transactions, transfers, categories, payees, notes, and split transactions. Add deterministic categorization rules whose matches can be inspected and undone. Provide reconciliation, monthly budget, cash-flow, net-worth, and export views. Keep an immutable import log and require explicit confirmation before destructive changes. Encrypt local data, create automatic backups, and document restore on a fresh machine. Include clear empty, loading, success, and recoverable error states. Add input validation, safe filenames, and graceful handling of unavailable APIs. Write focused tests for the core transformation and one end-to-end happy path. Create a README with setup, architecture, permissions, data location, and backup steps. Do not add accounts, billing, telemetry, analytics, or a hosted control plane. Deliberately leave out initiating payments or moving money. Deliberately leave out tax, payroll, or accounting compliance guarantees. Deliberately leave out screen-scraped bank access and commercial institution aggregation. Finish by running the tests and listing the exact commands used.

People still pay for Lunch Money because people pay because accurate money records and dependable institution connections are worth more than the visible charts. The recurring cost buys import normalization, reconciliation, rule drift, exchange rates, backups, audit trails, tax changes, bank APIs, and support, not just the visible interface.
