My AI Is Slow. So I Gave It the Night Shift 🌙

Description and use

Night Butler automatically processes bank statements, notes, and to‑do lists overnight, producing a morning page with categorized merchants, subscription alerts, price rises, duplicate charges, unusual bills, extracted to‑dos, merged duplicate tasks, and unresolved questions that require only a few clicks.

Problem

Boring paperwork such as bank statements, notes, and to‑do lists is often postponed because it is tedious.

Outcome

In a demo month of 100 transactions, 6 notes, and 14 tasks, Night Butler completed the night shift in 6 minutes on an Intel i5‑12450H laptop, producing a morning page that required only a short note and three clicks to review. On real data of 344 transactions over four months, it sorted 307 (89%) in 14 minutes and identified 23 unknown merchants.

Workflow

• Drop bank statement CSV, notes markdown, and tasks.md into a folder before bed
• Night Butler runs at low CPU priority during the night
• It parses each file, categorizes merchants, detects subscriptions, price changes, duplicate charges, and unusual bills
• It tags notes, extracts hidden to‑dos, converts relative dates to absolute dates
• It merges duplicate tasks
• It identifies unknown merchants and asks the user three clarifying questions
• Results are saved and presented as a morning page with a short note and actionable items

Evidence

Night Butler is a small open‑weight model on your own computer that does your boring paperwork while you sleep.

In the demo month the butler did, in 6 minutes of a laptop's spare CPU: sorted 97 of 100 transactions

The model now first writes what the merchant sells, then answers a yes/no: do you actually know this business?

The morning note first came out as "you have $97 in transactions to review" — 97 was a count.
