Bindrik turns your artwork into a KDP-ready interior and cover for Amazon print-on-demand. Bleed, gutter, page count, spine width and barcode zone are worked out from the numbers Amazon publishes, with trim and safe-area guides on every page. It is tested against a colouring book KDP already accepted. Runs offline on your Mac; nothing is uploaded. $69 once, no subscription, full-featured free trial (exports watermarked until you add a key).

Hi Product Hunt 👋 I'm Flavio.
I publish kids' colouring books on Amazon KDP, and the art was the easy part. What cost me days was geometry: KDP rejected files over a spine a fraction of a millimetre off and bleed on the wrong edge, none of which you can see on screen.
So I built Bindrik, a Mac app that does that arithmetic for you. Drop in your pages, pick trim size and paper, and it lays out the interior (gutter sized to the final page count, blank pages if you want them) and the full cover with the spine and barcode zone. Trim, bleed and safe-area guides show on every page before you export.
To keep it honest, every change rebuilds my own published book, Backyard Bug Crew, and compares it with the PDF Amazon approved. That test caught a 0.34 mm spine error that would have got the cover refused.
It runs fully offline, your artwork never leaves your Mac, and it's a one-time $69 with no subscription. The trial is the complete app; exports just carry a watermark until you add a key.
I'd love your feedback, especially from anyone who publishes on KDP: which trim sizes or page types should come next?
