Description

💬 Chat with Your Finances on Telegram

Ask questions like “How much did I spend on food last month?” and get instant answers from your financial data — directly in Telegram.

This workflow connects your Google Sheets expense log to an AI-powered query engine that understands natural language, resolves ambiguous categories and person names, and sends back a clean formatted summary in Telegram.

No spreadsheets. No dashboards.
Just chat with your financial data.

⚡ How it works

Simply send a message like:

• How much did we spend on groceries last month?
• Show me a breakdown by category for this week.

The workflow automatically:

1. Parses your intent using GPT-4.1-nano
2. Resolves categories and person names via mapping tables
3. Filters and aggregates expense data from Google Sheets
4. Returns a formatted summary directly in Telegram

If a category or person is unknown, the workflow uses AI to suggest the closest match and asks the user to confirm via Telegram inline buttons.

Confirmed aliases are saved automatically, making the system self-learning over time.
