Building with AI

An elegant, dual-pane personal finance tracker for logging daily, weekly, and monthly expenses and savings. The standout feature is automatic transaction capture: it connects to Gmail (read-only OAuth) to detect DBS Bank alert emails, then uses the Gemini API to parse each alert into a structured transaction — amount, category, and description — so I don't have to manually enter every purchase.

• Log a daily expense or saving entry in seconds via the dual-pane add form
• Let bank SMS/email alerts auto-populate transactions via Gmail sync
• Gemini AI reads each bank alert and classifies category + amount automatically
• Check today / this-week / this-month / all-time totals at a glance
• Browse spending by category — Food, Transport, Bills, Rent, and more
• Track savings sources separately — Salary, Investments, Side Hustle, Refunds
• Switch between multiple country/currency formats and locales
• Export the full transaction history to Excel (.xlsx) for records
• Works fully offline with local persistence; syncs to Firebase when online
• Dark mode built in for low-light daily use

export type TransactionType = 'saving' | 'expense';

export interface Transaction {
  id: string;
  type: TransactionType;
  amount: number;
  category: string;
  description: string;
  date: string; // YYYY-MM-DD local format
  createdAt: string; // ISO format Timestamp
}

export interface SummaryStats {
  today: number;
  thisWeek: number;
  thisMonth: number;
  total: number;
}

A mobile-first tracker for logging investment payments, managing multiple savings schemes, and monitoring portfolio growth over time — built to handle the mixed basket of instruments I actually use: recurring deposits, SSY, stocks, mutual funds, and chit funds, all in one place, with full offline persistence.

• Set up a "scheme" for each instrument — RD, SSY, Stocks, MF, Chit, or Custom
• Record the monthly SIP amount and the platform/provider for each scheme
• Log a monthly entry per scheme — amount invested vs. current value
• See return % calculated automatically per entry and per scheme
• Add notes and payment mode (bank transfer, UPI, auto-debit, etc.) per entry
• Review portfolio P&L across every scheme in one consolidated view
• Keep logging and reviewing fully offline — data persists locally on-device
• Sync across devices via Firebase when back online

export type SchemeType = 'RD' | 'SSY' | 'Stocks' | 'MF' | 'Chit' | 'Custom';

  id: string;
  name: string;
  type: SchemeType;

  plat: string;
  userId?: string;
  createdAt?: string;
}

export interface Entry {
  id: string;
  month: string;          // YYYY-MM
  date: string;           // YYYY-MM-DD
  schemeId: string;
  schemeName: string;
  schemeType: SchemeType;
  amount: number;
  currentValue: number;
  returnPct?: number;
  mode: string;
  notes: string;
  userId?: string;
  createdAt: string;      // ISO timestamp
