Every world, every cover design, every age group, so no two books look the same.
12 more theme worlds and your own typed themes, 7 cover designs in 8 colour schemes, 4 book fonts, up to 8 chapters, pick the puzzle types yourself, and books for ages 10+.

Your first five books look like five books. Your twentieth looks like the fifth.
The front end has five worlds, two cover designs and one font, which is plenty for the first books. A shop or a KDP catalogue needs variety: a Halloween book should not look like the Space book, a grade-6 escape room should not look like a Pre-K board game. Worlds & Looks is the variety.
What Worlds & Looks unlocks, exactly
- 12 more worlds: Dragons & Castles, Robots, Farm, Superheroes, Winter, Halloween, Thanksgiving, Christmas, Valentine's Day, Easter, Pi Day, Birthday PartyEach world has its own hero, places, treasures, icons and story templates. Plus your own typed theme: type "volcanoes" or "ballet" and the app builds the book around it with the generic world's icons.

How it works
Type the code from your thank-you page in the app. The locked worlds, designs, fonts and the ages-10+ option open in New book.
Pick a world (or type one), a design, a colour scheme and a font in step 4. Everything else is the same four screens.
The Pictures step lets you change the cover design and colours of any book, including books you made before the upgrade.
What it does not do (read this before you buy)
- It adds worlds, looks and options; it does not add puzzle types (the front end already has all 33) or AI. Stories still come from the story templates; AI-written stories are ELITE.
- The 12 season packs (New Year, Spring, Earth Day, Back to School and so on) are not in Worlds & Looks; they are the Seasons Vault.
- A typed theme uses the generic world's icons and places, so it is less specific than a built-in world.
- Books for ages 10+ use grade-6 lessons; there are no lessons above grade 6.
- Still English only, and still your job to look at a book before you publish it.

It's for you if

- You want holiday books (Halloween, Christmas, Valentine's and the rest) or books for ages 10+.
- You want to choose the puzzle types yourself.
It's not for you if
- Five worlds and two designs are enough for what you print at home.
- You want AI pictures: that is ELITE, not this.

Is the holiday that is "coming up" still free in the front end?
Yes. The front end always has the next holiday. Worlds & Looks gives you all of them all year.
One-time?
Yes. $37 once, 30-day refund.
Where do I get help?
Email leo@leosterling.net. We answer within three working days, usually sooner. The Guide panel in the app has a section for this upgrade.
30-day money-back guarantee
Try it for 30 days. If it is not for you, email support with your WarriorPlus order id and you get the full price back, no questions asked. The upgrade is switched off; books and files you already made stay yours. EU and UK consumers: this is longer than, and includes, your 14-day right of withdrawal.
Earnings disclaimer. Worlds & Looks is software (and, for the Academy, lessons), not a business opportunity. Nothing on this page promises that you will sell any book or earn any money; results depend on your work, your listings and your market, and many sellers earn nothing.

AI. Where an upgrade uses AI (ELITE), it runs on your own OpenRouter key and you must declare AI-generated content on KDP and add the AI note on Etsy as their rules require. The other upgrades use no AI.
