Billy

Billy is an AI-powered Telegram bot that helps groups track shared spending for trips, events, and everyday expenses. It accepts both voice messages and text commands, turning them into structured entries in a shared budget.

What Billy does

Billy works inside Telegram group chats, so there’s no separate app to install. It can transcribe voice notes, add expenses to the group total, and calculate who owes what.

• Add expenses via voice messages
• Add expenses via text commands
• Speech-to-text recognition for faster entry
• Support for 20 currencies
• Split expenses among group members
• Reminders for unrecorded expenses
• Export results to a CSV file

A notable technical detail is its use of LLVM for voice processing, which the service says makes it about 2× faster than similar tools.

How to use

• Open Telegram
• Find @BillyMoney_bot
• Add the bot to a group chat
• Send a voice message with an expense, or enter the amount and category in text
• Confirm the expense entry
• Request a final report when needed

Billy is free and doesn’t require registration. The bot supports Russian and English, and voice processing works in 15 languages (including Chinese and Spanish).
