“What did this cost to make?”
Answered. Instantly.
Drop in an item — the math is already done.
Materials, hours, true cost: Kanau keeps it all in one place.
What it cost. How much you used.
That’s everything Kanau needs.
= ¥80
Pick the model that fits — per piece or per volume — and the cost of each piece falls out automatically. Add your hours at an hourly rate, and your pricing stops being a guess.
Checkboxes included: the same list doubles as a shopping list and a build tracker.
Keep your hands making.
A calculator for every situation
By the piece, by volume, by the hour. The fiddly division is Kanau’s job now.
Your hours count
Time your work sessions and tally them up. See what a piece is worth when your time is paid fairly.
Organize with tags
“Consignment”, “craft fair” — tag projects any way you like and filter them in one tap.
Photos and links, attached
Keep material photos and shop links right on the item. Copied an image? Just paste it.
Integrations
Manage data through Claude, save pages with a bookmarklet, or share from Safari in one tap.
Dark & minimal
Minimal mode strips the screen down to the essentials. Dark mode included.
