NoteBrain turns your phone into a banknote identifier and value checker. Photograph a note and get its country, denomination, series and issue year, along with an estimated collector value.

Whether you are going through an inherited box of currency, checking change for something unusual, or pricing a note before you sell it, NoteBrain gives you a starting answer without hours of catalog searching.

IDENTIFY ANY BANKNOTE
Photograph the note and the AI reads the design, portrait, seal and printed text to name the issue and show a match accuracy score. Works on United States large and small size notes, silver and gold certificates, federal reserve notes, and world banknotes.

READ THE SERIAL NUMBER
Point the camera at the serial and NoteBrain reads it, then tells you whether it is a star note and whether the pattern is collectible. It checks for solids, ladders, radars, repeaters, low numbers and other fancy serial patterns that carry a premium over face value.

SPOT ERRORS AND VARIETIES
Misalignments, ink smears, cutting errors, mismatched serials and other production mistakes are flagged with the reason they matter to collectors, so you know when an ordinary looking note is not ordinary.

ESTIMATE GRADE AND RARITY
Answer a few guided questions about centering, corners, folds and paper quality and NoteBrain estimates where the note is likely to sit on the standard paper money grading scale, from circulated grades up through uncirculated. Useful for deciding whether a note is worth submitting for professional grading.

CHECK COLLECTOR PREMIUMS
Every identification comes with an estimated market value so you can see when a note is worth more than the number printed on it. Values are estimates drawn from market data, not appraisals or offers to buy.

TRACK YOUR COLLECTION
Organize notes into albums by country, series, condition or theme. See your collection total and how it has moved over time, and keep your scan history so you can look a note up again later.

BROWSE AND LEARN
Catalogs cover US large size, US small size and world banknotes, plus what is currently in demand. Short explanations tell you what makes a note scarce, valuable or collectible, so the app teaches as you use it.

IMPORTANT
NoteBrain is a reference and hobbyist tool. Identifications, grades and values are produced by automated systems and may be incomplete or out of date. NoteBrain does not grade, authenticate or certify currency and is not a substitute for professional grading, appraisal or financial advice.

SUBSCRIPTION
NoteBrain is free to download and includes a 7-day free trial of full access. After the trial, weekly and yearly subscriptions are available, priced in your local currency and shown in the app before purchase. Subscriptions renew automatically until cancelled; manage or cancel any time in your Google Play subscription settings.
