How they work

No account

There's nothing to sign up for. Flip Studio keeps your lists in your browser, and Coin Spotter keeps its scans in your browser or on your phone. Back up or export whenever you like.

Your own AI key

Coin Spotter runs on Gemini or Claude with a key you create. It goes only to that provider, straight from your browser or phone, and you pay them directly, or nothing on Gemini's free tier.

True to size

Labels and separator cards are laid out in millimetres for HERMA 10900 sheets and 50 × 50 mm flips. Print at 100 % and shift by tenths of a millimetre to match your printer.
