DIA

[ Overview ]

DIA is a multi-platform AI budget coach born from a personal problem: making more money but watching savings stay flat. Users log expenses, track budgets, and manage savings goals through natural language across Telegram, WhatsApp, and Discord — no app download, no spreadsheets, just type and track. Named DIA (from Spanish "día" — day, but also the Filipino "diyá" — self), it's designed to make daily money management invisible and conversational.

[ Key challenges ]

• • Natural language expense parsing — extracting amounts, categories, and recurrence from casual chat messages
• • Multi-platform bot architecture — each platform (Telegram, WhatsApp, Discord) has unique API semantics and rate limits
• • Cross-platform state consistency — user can log an expense on Telegram and check their budget on Discord
• • Expense categorization from ambiguous language — "50 for lunch" vs "50 for the electric bill"

[ Key features ]

• • Natural language expense logging — "spent 45 on groceries" creates a categorized transaction
• • Budget tracking with configurable monthly and category-specific limits with real-time alerts
• • Savings goal management with progress tracking, milestone celebrations, and streak rewards
• • Cross-platform support — Telegram, WhatsApp, and Discord with synchronized state across all three
• • Spending analytics with weekly summaries, category breakdowns, and trend comparisons
• • Natural language queries — "how much did I spend on food this month?" returns instant breakdown
