Bills become questions you can actually ask
Understand your bill. Know what to ask next.
ExpenseReader is a free AI bill analyzer and bill explainer that helps you understand charges. It separates what a document says, what the arithmetic supports, what remains unknown, and which follow-up questions may be useful.
Penny Lane is ExpenseReader's AI bill-analysis expert.

Penny Lane’s notebook
Recently published guides
AI-generated educational articles, published automatically only after source, safety, and rendering checks.
insurance
Annual premium, installment, and amount due are not synonyms
A renewal notice can describe the price for a policy period, the way that price is billed, and the payment requested now. Those figures answer different questions and do not establish coverage for a hypothetical loss.
utility
Why minus signs matter when a utility total is checked
A signed, line-by-line reconciliation can show whether displayed components reproduce a statement total without deciding whether any charge is justified.
credit card
Reconcile a card cycle without inventing an interest formula
Use signed balance movements to reproduce a printed closing balance while keeping interest-method details clearly unknown.
saas
An invoice total and a receipt total answer different questions
How status, dates, credits, and amount due help distinguish a software payment request from a record of payment.
Privacy, stated precisely
Your privacy is built into every analysis
01
Review before AI
You correct and mask extracted text first. Detection helps but can miss sensitive details.
02
PDF stays out of the model
ExpenseReader sends only the corrected text for analysis, never the original PDF bytes.
03
App state is temporary
The page uses in-memory state. Provider and hosting processing are separate and described in the privacy notice.
Analyze your own document
A private, correctable workspace
Use already-redacted text when possible, or choose one PDF. A readable text layer is extracted first; eligible printed pages can use browser-local OCR when enabled. Your result and follow-up conversation remain in this browser tab.
Analyze your own document
Private bill workspace
Session-only · refresh loses your work · five analyses per UTC day, subject to the shared budget
Start with a copy, not your only document.Remove names and identifiers. Automated detection is incomplete. The app does not save document content, but provider retention is a separate process described in the privacy notice.
