Sansuu Royalty Review OTO 2026: Hands-On KDP Math Workbook Test | Worth $37?

I spent a week cranking out math workbooks for KDP. Here's exactly what worked, what flopped, and if this $37 tool beats the old grind of manual formatting and answer keys. 

Sansuu Royalty Review 2026: What Nobody Tells You Before You Buy (Hands-On Test + Real Talk)

Sansuu Royalty review after 7 days testing: auto math worksheets, KDP-ready PDFs, answer keys. Real workflow, pricing, bonuses for KDP sellers. No hype, just results.

Hey, if you're knee-deep in the KDP game or just dipping your toes into print-on-demand side hustles, you've probably stumbled across Sansuu Royalty. It's popping up everywhere in those WarriorPlus feeds—promising to spit out ready-to-sell math workbooks without you breaking a sweat on equations or layouts.

I get it. You're skeptical. I've been there. Another AI tool? Another "passive income" pitch? I felt the same way before I grabbed access. But math workbooks? That's a niche with real legs—parents grabbing practice sheets for kids, teachers stocking up on Etsy or TPT, steady sales if you hit the right sub-niches like "3rd grade multiplication drills" or "fraction basics for homeschoolers."

This isn't some fluff piece. I tested it for seven straight days. Created full books. Exported to KDP specs. Even mocked up listings. No fluff, just what I saw. By the end, you'll know if this fits your workflow or if it's just hype.

Quick heads-up: Some links here are affiliates. If you buy through this page, I might earn a commission at no extra cost to you. My take is 100% my own—tested it myself.

Let's dive in.

Why I Dropped Everything to Test Sansuu Royalty

Picture this: It's a Tuesday night. I'm staring at my screen, half-finished Canva template for a kids' addition workbook. I've spent two hours typing problems by hand. Then the answer key? Forget it—calculator out, double-checking 50 sums, praying no typos slip into the final PDF.

Sound familiar? If you're chasing KDP royalties or Etsy printables, math workbooks look easy on paper. Evergreen demand. Low competition in specifics like "decimal rounding for 4th graders." But the grind? It kills momentum.

That's me last month. I'd published journals and puzzles before, but math? Nope. Too fiddly. Then Sansuu Royalty lands in my inbox. Cloud-based. One-time fee. Auto answer keys. KDP-ready files. Claims it handles 20 math categories, 60+ types.

I bit. Paid the $37 front-end. Logged in. No install, just browser. First workbook: 15 minutes flat. No joke.

But was it a fluke? I committed to a week. Built 10 books. Tested exports on KDP previewer. Ran keywords through it. Here's the raw story—no sugarcoating.

Breaking Down Sansuu Royalty: The Basics Without the BS

Sansuu Royalty comes from Ike Paz and Luke Bowes—guys who've shipped KDP tools before. "Sansuu" means arithmetic in Japanese, nods to the core: math drills for kids up to middle school.

It's pure cloud. Fire up Chrome, log in, done. No apps, no APIs, no ChatGPT prompts. Picks from categories like addition, fractions, long division. Tweaks difficulty: easy, medium, hard. Spits out worksheets, pages them into books, adds answer keys. Exports PDF or PNG, sized for KDP trims like 8.5x11 or 6x9.

Launched April 2026 on WarriorPlus. Front-end gets you the math engine. Upsells add bulk, kid stuff, science. But core? Solid for starters.

Not a general book maker. Laser-focused on math sheets. That's the hook—or the limit, depending on your stack.

The Ugly Truth: Why Math Workbooks Kick Your Butt Without a Tool Like This

Let's talk pain first. You can't sell what you don't make. Manual math books? Hell.

Start with problems. Free generators online? Glitchy. Wrong logic, pixel mess when printed. Type in Word? Fractions look like crap—brackets off, alignments shot.

Then layout. Margins for bleed? KDP's 0.125-inch rule trips everyone. Pages must flow: headers, footers, problem numbers. One slip, rejection.

Answer keys. Killer. 100 problems? Solve 'em all. Errors mean bad reviews: "Parent here, book has mistakes!"

Covers? Canva drag-drop, but trim-specific spines? Trial-error hell.

Time sink: One 50-page book? 4-8 hours easy. Scale to 20 for catalog? Weeks gone.

Stuck creators message me: "I have niches, no interiors." Teachers too—want TPT cash, hate formatting. Homeschool moms scaling printables? Same boat.

Sansuu flips that. Handles the grunt. Leaves you niches, listings, ads.

Day in the Life: My Step-by-Step Run Through the Workflow

Not a sales demo. My real clicks.

Log in. Clean dashboard. No clutter. Sidebar: categories. Top: new workbook button.

Pick category. Day 1: addition. Sub-options: single-digit, carry-over, word problems. 20 groups total—skip counting, place value, PEMDAS, etc. Felt complete, not sparse.

Set details. Difficulty slider: easy for K, hard for grade 6. Pages per sheet? 20 problems/side. Borders? Dotted or plain. Margins auto-KDP. Fonts crisp, print-friendly.

Generate. Hit go. 30 seconds: 10 worksheets pop. Structured—progressive difficulty. No repeats.

Answer keys. Magic here. One click: full section, solved perfectly. No calc needed. Matched problems 1:1. Spot-checked 20: flawless.

Bulk mode. Day 2: mixed ops book. Select 5 categories, 40 pages. 2 minutes. Consistent flow.

Export. Choose trim: 11 options, like 8.5x11 bleed-set. PDF crisp, 300 DPI. PNGs for Etsy tweaks. Uploaded to KDP previewer: perfect. No resize hacks.

Covers. Basic builder: templates, text swap, images. Not Photoshop. Good for "Grade 2 Addition Fun" vibe. Spine auto-calcs pages.

Full book: 20-40 minutes first try. Day 3: under 15.

Tweaks? Regen single page if off. No full restarts.

Feels like a shortcut, not cheat.

Features That Stick—and the Ones That Don't

Dug deep. Here's what holds up.

Core generators. 60+ types. Addition basics to error analysis. Examples: fact families (e.g., 3+4=7, so 7-3=4), estimation rounds. Grade-spanning. Created "rounding to nearest 10" sheet—kids love drills like 47→50.

Auto keys. Standout. Instant, accurate. Saved me 2 hours/book. Parents check, no rage-quits.

Trims and formats. 11 sizes. 6x9 popular for kids. Bleed, gutters right. No Affinity Publisher dance.

Bulk. Game-changer for volume plays. 100-page mixed? Done.

Keyword tool. Basic. Types "multiplication," suggests "grade 4 timed multiplication." Points to low-comp like "long division no remainder." Okay starter. Publisher Rocket better for pros.

Cover tool. Functional. Drag text, colors. Add kid icons. Export spine-ready. Beats Fiverr $20 gigs early.

Commercial rights. Clean. Sell unlimited. No vendor cut.

Filler? "Niche finder" repeats Amazon basics. UI smooth but mobile meh—stick desktop.

Overkill? Decor options (stars, lines). Cute, not essential.

Real Books I Built—and Where It Shines or Stumbles

Tested limits.

Kids' basics. "Kindergarten Addition to 10." 30 pages. Clean, big fonts. Perfect TPT printable. Etsy too—$4.99 digital.

Grade school drills. "Fractions Equivalent 1/2 1/4." Medium hard. Progressive: match, simplify, word probs. Homeschool gold.

Mixed bags. "Order Ops Grade 5." PEMDAS focus. Bulk-mixed subtraction too. Full 60-pager.

Shines: Repetition niches. "Skip counting by 5s." Scalable—tweak difficulty, new book.

Stumbles: Advanced. No algebra, geometry proofs. Custom stories? Nah. Structured drills only.

Platforms? KDP interiors flawless. Etsy PNGs editable. TPT bundles easy. Lulu/Blurb too.

One flop: High custom. Wanted "Christmas-themed decimals." No themes. Plain works, add Canva overlay.

Built 12 books. Catalog-ready.

Pricing: Every Dollar Broken Down, No Smoke

WarriorPlus launch style. Front-end low-barrier.

$37 Front-End. Math core, 100 PDF/mo exports (plenty for 10 books/week), trims, covers, keywords, training vids, case study. Commercial license. No sub.

That cap? Real. Hit 100? Wait month or upsell. Starters fine.

OTO1 $77 Moji + Bulk. ABC tracing, phonics, sight words. Unlimited exports. Kid expansion smart.

One-time beats subs like BookBolt.

Grab it here before price bumps. Early bird still live.

My Seven-Day Deep Dive: What Broke, What Clicked

Structured my test like real hustle.

Day 1: First Blood. Setup 5 mins. Addition book. Smooth gen. Export glitch—first PDF margins off (user error, fixed toggle). 45 mins total. Impressed.

Day 2: Variety Hunt. 5 categories: sub, multi, div, fractions, decimals. Patterns emerged—logical progression. Bulk test: 20 pages mixed. 10 mins. Answer keys? Spot-on.

Day 3: Answer Key Deep Test. Created 100-prob division. Manual check 20%: perfect. No "12/3=5" idiocy. Workflow shift: focus design, not math.

Day 4: Full Book Build. 80-page "Grade 3 Math Mastery." Bulk + manual pages. Cover matched. KDP upload preview: green lights. 25 mins.

Day 5: Edge Cases. Skip count, place value. Keyword tool: "2nd grade place value hundreds." Low comp alert. Cover builder limits: text wrap iffy.

Day 6: Platforms Play. Exported PNGs, Canva'd Etsy mock. TPT bundle: 5 books zipped. KDP live test account: approved.

Day 7: Scale Sim. 3 books/hour pace. Month? 60+. Reflected: Tool owns production. Now listings matter.

Changed me? Production barrier gone. From stalled to shipping.

Sales Page Real Talk: Where It Stretches Truth

Love the product. Page? Classic launch.

"Passive royalties day in day out." Upload helps, but Amazon ranks on sales velocity, reviews, keywords. One book? Crickets likely. Catalog + promo = flow.

"Free buyer traffic." Platforms have eyes, but compete 10k+ math listings. Ads OTO admits push needed.

"97% automated." Production yes. Niche pick, titles, A+ images? On you.

Earnings pics: $4k one seller. Cool. No "how many books? Ads?" Context missing.

Value stack $4096? Launch trick. "Speed $220." Fun, not real.

No refunds + claims = buyer beware front-end.

Honest marketing would've sold me faster.

Who Grabs This—and Who Bails

Buy if:

• KDP newbie. Structured start beats blank page.

• Volume chaser. 50-page books quick = catalog king.

• Teacher/parent. Monetize drills sans hassle.

• Mid-content stacker. Pairs journals, puzzles.

• Fiction writer. Wrong tool.

• Pro designer. Too basic.

• One-and-done dreamer. Needs grind.

• Advanced math needs. Pre-calc? Look elsewhere.

Me? Fits. Scaling education now.
