This is the personal finance setup I actually use to run my own money. A Telegram bot on top of n8n that logs transactions by text, voice, or receipt photo. It scans two Gmail accounts every minute for receipts and subscription emails, registers new subscriptions, catches cancellations and payment failures, and sends a full financial snapshot every Friday morning.
Ask it anything: balance, net worth, how the food budget is doing, what you spent at Starbucks last month, or how much 5000 THB is in AUD right now. Reply 'wrong currency' to any confirmation and the row updates. Say 'I need $20 more for gifts, where can I move it from' and it reads your Categories tab and suggests the move.
1 main workflow. 8 atomic sub-workflows. 1 error notifier. Importable into any n8n instance. Paste your API keys and the agent is live.
Built on n8n, Gemini 2.5 Flash, and a Tiller Finances Google Sheet. Setup takes about 15 minutes.
The exact n8n setup I use to run my personal finances on Telegram. Free.
