FinBot Development: AI-Powered Financial Assistant

💸 FinBot — AI-Powered Personal Finance Assistant Built With n8n
An intelligent Telegram bot that captures, organizes, and analyzes your personal finances in seconds using AI.
📋 Overview
Traditional expense tracking is slow, repetitive, and easy to abandon. Most finance apps require multiple manual steps just to record a single transaction.
FinBot removes that friction.
Simply send a text message, receipt photo, or voice note through Telegram, and the AI automatically understands, categorizes, and stores your transaction—without opening another app.
🌟 What Makes FinBot Different
Most finance bots only support today's date and offer rigid, one-size-fits-all reports. FinBot is built to handle how people actually think about their money:
Log transactions for any date, not just today.
Say "paid electricity bill yesterday" or "lunch on July 5th, 45k" — the bot understands the time reference and records it under the correct date, not the date the message was sent.
Ask for the report you actually want.
Beyond simple daily/weekly summaries, you can request reports by custom date and date range, filtered by category, or filtered by payment method — just by asking in plain language, no menus or filters to configure.
✨ Key Features
💬 Natural Language Input — Log income or expenses in plain conversational text, with flexible date recognition (today, yesterday, or a specific date).
📸 Receipt Scanner — Extract transaction data automatically using AI-powered OCR.
🎙️ Voice Recognition — Talk to the bot instead of typing — voice notes are transcribed and routed through the same AI pipeline as text, so you can log a transaction, ask for a report, or ask a financial question, all by voice.
🤖 AI Intent Detection — Automatically understands whether you're recording a transaction, requesting a report, or asking financial questions.
📊 Flexible Reports — Daily, weekly, monthly, custom-date and date range, or filtered by category and payment method.
💡 AI Financial Chat — Ask questions about your own spending habits and receive contextual answers.
⚡ Fully Automated Workflow — No manual categorization or data entry required.
🛠️ Tech Stack
⚙️ n8n — Orchestrates the entire automation workflow

🏗 Workflow Architecture
Every incoming message is normalized into a single data format before being processed by an AI-powered routing system.
How It Works
📥 Input Handling
The bot accepts 3 input types — typed text, voice notes, and receipt photos. Each is normalized into a consistent
text field before further processing.🧠 Intent Classification
Classifies the user's message into one of four intents — transaction, report, chat, or fallback — including period and filter detection for report queries.
🔀 Routing
Routes to the matching branch based on the classified intent. Photo input skips this step entirely — receipts always go straight to the Transaction branch.
💰 Transaction Branch
Extracts structured data (date, category, amount, payment method) via LLM, validates that it's not empty, then logs the entry to Google Sheets with an auto-calculated running balance.
📊 Report Branch
Filters transactions by period (today/week/month/custom) and by category or payment method, then returns income, expenses, and running balance.
💬 Chat Branch
An AI agent answers general finance questions and can pull transaction history from Sheets when the user asks about their own data.
⏰ Scheduled Report
Sends a daily financial report automatically at 7 PM, using the same Report Branch logic as manual requests.
⚠️ Fallback
Catches unclear messages and failed voice/photo extraction — guiding the user with example commands instead of leaving them stuck.
