How to track expenses in Telegram (no app to install)

Why Telegram is a surprisingly good expense tracker

A Telegram bot has three things a normal expense app doesn't. There's nothing to install — if you have Telegram, you have it. There's no context switch — you're already in your messages, so logging a receipt is the same gesture as sending a text. And it works on any phone — iPhone or Android, plus desktop and web — because it's just a chat.

That sounds small, but friction is the whole game. An expense tracker only works if capturing a receipt takes seconds and zero willpower. A chat clears that bar.

The four ways to capture a receipt

The point is to match how you actually remember a purchase, so there's always a path of least resistance:

• Snap a photo. Point your camera at any receipt — faded thermal paper to a glossy A4 invoice — and send it. AI reads the shop, date, line items, tax and total.
• Say it out loud. Didn't grab the receipt? Send a voice note: "lunch at Tian Tian, twelve sixty." It transcribes and files it like a photo.
• Forward a PDF. Digital receipts from Lazada, airlines or hotels — just forward the email's PDF and it parses the text.
• Type it. For cash and hawker stalls: /spend 5.50 laksa, or just "bought a coffee for 7 dollars."

What happens after you send a receipt

You get a clean confirmation card back — shop, date, line items, total, and a best-guess category. You tap Confirm, or Edit in plain English ("the total should be 9.50"), or Split it with friends. That's it. The receipt is now a structured entry you can search and total later, without ever opening a spreadsheet.

It handles the annoying parts too

Multiple currencies: yen in Tokyo, baht in Bangkok, euros in Lisbon — a good travel expense tracker reads the currency off the receipt, converts at the day's rate, and rolls everything into one home-currency total. Splitting a bill: tap the headcount to split the bill and it files only your share, so your budget isn't inflated by the whole table's dinner. Asking questions: later you can just ask, in normal words — "how much did I spend in Japan?" — and get an answer from your real receipts, no pivot tables.

The catch most chat-based trackers get wrong: your data

Convenience usually means lock-in. The thing to look for is where your receipts actually live. With Magpie, every entry is saved as a plain-text Markdown note you own — readable in any editor, droppable straight into Obsidian, exportable as a ZIP or deletable in one command, any time. It's never used to train AI. A chat is the convenient front door; plain files you control are what keeps you from getting trapped.
