Scan Receipt (AI)

Claude's AI vision reads your receipt for you. Pop in the group passcode (ask whoever shared the app) or your own Anthropic key. Either one stays in your browser and nowhere else. If the receipt has a service charge or GST line, those get filled in automatically.

Receipts

Scanned receipts land here on their own. Tap a photo to view it full size, or share it with the group so the bill stays out in the open.

Charges & Taxes

Quick setup for where you're eating:

Each charge can be a % or a flat amount, and you choose whether the % works off the items subtotal or the running total (handy for Singapore, where GST stacks on top of the service charge). All charges are shared out in proportion to what each person ordered.

Bill History

Archiving tucks this bill into history and starts a fresh one with the same crew, categories and tax settings. It even survives Clear everything. Load a saved bill to update it (for example, ticking off who has paid) and your changes save straight back to it.
