Welcome to CartLens!
Scan your Amazon orders to see your spending by category, track tax deductions, and more.
Checking for extension…
Scans your last few months of orders — takes about a minute.
⚠ Before you scan: make sure the Amazon account signed in on this browser is yours. CartLens will read whatever account is currently logged into amazon.com.
Scan a specific year. Opens Amazon and imports all orders automatically.
☕ Full year scans take a few minutes — CartLens is quietly visiting each of your orders in the background. Keep this tab open, leave your computer awake, and go grab a coffee. We'll let you know when it's done!

🔒 Your privacy is protected. CartLens never sees or stores your Amazon password, payment info, or personal details. We only read item names, prices, and order dates — nothing else.
During early testing, each CartLens account should connect to one Amazon account only. If multiple CartLens accounts scan the same Amazon login, the second scan won't import — we're working on shared-household support as part of the next release.
