Stop Logging Expenses by Hand — Let the AI Handle It
Four ways to get spending into your log, real-time push alerts when something is captured, and a daily recap to keep everything accurate — all in one place.
Receipt scanning that actually works
Photograph a crumpled receipt or upload a PDF invoice. The AI pulls out merchant, total, date, and category in seconds — even on tricky handwritten or faded paper.
Log expenses by just talking
Describe a purchase the way you'd say it out loud and the AI turns it into a clean, categorized record. No forms, no dropdowns — just a sentence and you're done.
Full manual override, always
AI is optional. Create, edit, or delete any entry by hand whenever you want. Your data, your rules — automation helps but never gets in the way.
Real-time spend notifications
The instant a purchase is detected from your inbox, a push notification lands on your phone. Know what was captured before you even open the app.
One daily recap to stay on top
A morning summary lands each day listing everything captured in the last 24 hours. Scan, approve, or fix in seconds — month-end stops being a chore.
How it works
Pick Your Capture Method — Or Use All Four
Each method fits a different situation. Mix and match freely. Everything ends up in the same searchable, exportable log.
Photograph or upload your receipt
Point your camera at any paper receipt, or drop in a PDF or image — Inform Debtor handles scanned, photographed, and digital formats.
AI pulls out the key details
Merchant, total, date, and category are read and filled automatically. The model handles messy fonts and partial receipts too.
Save to your log in one tap
Glance at the pre-filled entry, tweak anything that needs it, and tap save. The record is instantly part of your exportable expense history.

What People Say After Ditching Manual Expense Tracking
"Connected my inbox on a Tuesday and by Wednesday I had two weeks of forgotten expenses already sitting in my log."
"I just describe what I bought and it shows up categorized. Feels like cheating compared to every expense app I used before."
"Scanned a receipt from a market in Lisbon. Got the merchant, amount in EUR, and the right category. Didn't have to touch it."
"The AI turns one sentence into a full expense entry. I said 'lunch $38 with sales team' and it was done in three seconds."
"Knowing my emails aren't stored anywhere made this an easy yes. The privacy model is different from every other app I looked at."
"Fastest expense capture I've found. Open the app, say the expense, done. Nothing else comes close on Android."

FAQ
Frequently Asked Questions
How inbox sync, receipt scanning, chat entry, and notifications actually work — answered plainly.
You connect your Gmail, Outlook, or IMAP inbox through a secure OAuth flow — no passwords are ever stored. Inform Debtor watches for incoming purchase confirmations, extracts the merchant name, amount, date, and best-fit category, and adds a clean record to your log. Nothing else from your inbox is read or retained.
Point your camera at any paper receipt or drop in a PDF. The AI reads merchant name, total, date, and suggests a category — and handles faded ink, unusual layouts, and non-English receipts reasonably well. You see the pre-filled entry before it's saved and can correct anything before confirming.
You type a natural sentence — something like "Client dinner $58 at Ember, Friday evening" — and the AI parses out merchant, amount, date, and category in under two seconds. The result shows as a draft entry for you to approve or adjust. There are no fields to tab through, no dropdowns to open.
No. Every entry can be created, edited, or deleted entirely by hand. The manual entry form covers all the same fields — merchant, amount, date, category, notes — and those records appear in the same reports alongside anything the AI created. Think of the AI as a shortcut, not a requirement.
Two types. First, an instant push the moment a new expense is detected from your inbox — so you know right away what was captured. Second, a daily digest each morning summarizing everything from the previous 24 hours. Tap either to open the entries directly and approve, edit, or remove them.
Use inbox sync as your baseline — it catches most recurring purchases with zero effort once you connect. Add receipt scanning for in-person purchases or paper invoices that never hit your inbox. Reach for chat entry when you want to log something quickly without stopping to take a photo. All three feed the same log, and you can switch between them freely.
