Ledgerly – Telegram bot for lazy families

Description and use

Ledgerly bot automatically processes receipt photos, verifies totals, and forecasts the day the household budget will run out, enabling users to adjust events and gifts.

Problem

Families need a way to track spending and forecast when their budget will run out without manually entering receipts and dates.

Outcome

The bot automatically processes receipts, verifies totals, and forecasts when the household budget will be exhausted, allowing users to adjust upcoming events and gifts to stay within budget.

Workflow

• Send receipt photo to Telegram bot
• Gemma extracts items and totals
• Python code verifies sum matches total
• Bot stores receipt
• User sends plain text event (e.g., "Arman's birthday is Dec 14")
• TabPFN predicts budget depletion day (Wall Day) and displays chart
• User asks about gift impact, bot updates forecast

Evidence

Send it a photo of a receipt. Gemma reads it, and plain code checks that the items add up before anything is filed.

Source

Gemma turns photos into rows, and chat into small commands like "add this event".

Source

TabPFN, through the Prior Labs API, looks ahead.
