AI-Powered Receipt & Expense Tracker: Telegram, Sheets, OpenAI

This workflow revolutionizes expense management by capturing receipts and expenses via Telegram in any format—text, photos, voice notes, or PDFs. It intelligently detects content type, transcribes voice with OpenAI Whisper, extracts text from images using Google Vision OCR, parses PDFs with LlamaIndex, and employs OpenAI GPT-4 for smart categorization into income/expense types with subcategories like Food or Transport. Currency parsing and validation ensure accuracy before appending detailed records (date, merchant, amount, category) to Google Sheets.

Benefits include zero manual data entry, error reduction through AI validation, real-time tracking via chat interface with inline menus, and seamless integration with cloud tools. It saves hours weekly on bookkeeping, supports multi-currency, and includes error handling for robust operation.

Ideal for small business owners, freelancers, digital nomads, and finance teams. Use cases: Snap a receipt photo on-the-go and get it logged instantly; dictate expenses via voice while traveling; upload PDFs for batch processing. Customizable prompts and templates enhance flexibility for personal or team finance automation.
