Bindrik — uma solução Tavlabs

Books Amazon accepts,
built on your Mac.

Bindrik turns your artwork into a KDP-ready interior and cover — bleed, gutter, page count, spine width and barcode zone worked out for you. One purchase. No subscription. Nothing uploaded anywhere.

Download and try it free

One-time purchase, includes one year of updates. macOS 12 or later, Intel and Apple silicon. The trial is the full app — exports carry a watermark until you paste your key.

KDP rejects on geometry, not on art

A spine a third of a millimetre too wide. Bleed on the inner edge, where it does not belong. A gutter sized for 90 pages when the interior came out at 86. None of it is visible on screen, and all of it comes back as a rejection days later.

Bindrik does that arithmetic from the numbers Amazon actually publishes, and shows you the trim, bleed and safe area on every page before you export.

What it does

Interior

Your images laid out at the right trim size, with bleed on the outside edge only and the gutter sized for the final page count — recalculated when the count changes.

Cover

Front, spine and back as one piece. Spine width from your real page count and paper stock, with the barcode zone kept clear.

Preview that tells the truth

Trim, bleed and safe-area guides on every page, so you see the problem before Amazon does.

Stays on your Mac

No account, no upload, no cloud. Your artwork never leaves the machine, and the app works with the Wi-Fi off.

It was checked against a book Amazon already accepted

Bindrik rebuilds Backyard Bug Crew — a colouring book published on KDP — from its original artwork, and the result is compared against the exact PDF Amazon approved. That test runs on every change.

That 0.34 mm is not a hypothetical. The spine was being calculated from 92 pages while the interior had 86 — enough for KDP to refuse the cover. The test found it.

Publishing low-content books is a thin-margin business. A tool that bills you every month whether you publish or not is working against that.

Questions

How do I get the app after paying?

The download is public — the link at the top of this page is the full app. Paying sends you a licence key by email, which removes the watermark from your exports.

What does the trial actually limit?

Nothing except the watermark. Every feature works, so you can rebuild a real book and check the output before deciding.

What happens after the first year?

The app keeps working, with every version released in that year. It does not expire and it does not phone home. Future major versions will be a paid upgrade, never a subscription.

The email has not arrived.

Check your spam and promotions folders first. Bindrik launched this month, so the address that sends licence keys is new and mail providers have no history for it yet. The email comes from licencas@licencas.bindrik.com, subject Your Bindrik licence key. If it is not there either, write to support and we will reissue it.

I lost my key.

Email us from the address you bought with and we will reissue it.

Does it write the book for me?

No. Bindrik does not generate content and has no AI in it. You bring the artwork; it handles the geometry and the export.
