Detective Maker Review – Can You Build A Murder Mystery Puzzle Book Without Designing A Page?

Puzzle books are having a real moment. UK puzzle-book sales volume grew 91% from 2019 to 2025, and the Murdle series alone has passed four million copies worldwide. Readers who are tired of word searches and sudoku have found something more satisfying: a short murder case with suspects, weapons and locations, a handful of clues and a grid to work out who did it.

Few self-publishers build these books, because they’re hard. Every case needs a fair story, clues that lead to exactly one answer, a deduction grid and a clean page layout, and doing it by hand can take a week per page. Detective Maker does that work for you. I used it to publish a detective puzzle book in two languages, and in this review I’ll cover what it is, how it works, the creators, the price, the upgrades and how the book sold.

What Is Detective Maker? How Does It Work Step By Step?

Detective Maker is cloud software that creates complete, solvable detective puzzle pages and lays them out for print. From a case idea, it generates the mystery story, case description, suspects, locations, weapons, deduction clues, logic relationships, elimination grid and solution, then arranges everything into a print-ready page with a matching solution page. You can write the case script with the free Detective JSON Maker MCP plugin in ChatGPT, with your own API key inside the tool, or with the built-in BrosAI models, and export your pages as PNG or PDF. It runs in the browser on Mac and Windows, works in 10 languages and comes with a commercial license.

Here’s the step-by-step flow as I worked through it:

➤ Step 1 — Bring the idea. Give Detective Maker a premise, such as a missing heirloom in a locked study, and choose your theme and tone. The AI builds the case, the suspects, the clues and the twist, and the solver checks that the logic leads to one fair answer.

➤ Step 2 — Get your polished pages. The case is laid out automatically into a puzzle page and a matching solution page, with the story, suspect cards, clue list and elimination grid in place. There’s no design work to do.

➤ Step 3 — Edit the story your way. Refine any part of the script, move blocks, adjust margins and numbering, add pages and show or hide the solution. When the book looks right, export it as PNG or PDF for KDP, Etsy or printing.

My first full case page, from premise to exported PDF, took about ten minutes, and most of that time went into tweaking the story to my taste.

About The Creator

Detective Maker is created by Anton Fui, Radahn Ha and Ryan Keikichi, the three co-founders of The Bros Studio LLC. Their studio focuses entirely on tools for self-publishers, and they have built a whole ecosystem of puzzle and activity book makers, including Word Search Maker, Nonogram Maker, Train Tracks Maker, Dot Marker Maker, Color By Number Maker, Word Fill In Maker, Monochrome Mosaic and Imagine AI.

That track record shows in Detective Maker. It feels like software built by people who publish puzzle books themselves: page sizes and margins made for KDP, a solver that checks every deduction, and tools that let you stay in control of the story. The video training is clear, BrosAI credits work across the whole studio’s tools, and the team runs a VIP Facebook group for users. It’s the kind of team I’m happy to trust with a full book.

Detective Maker Review – Key Features

✅ Automated Puzzle Creation And Page Layout: Detective Maker generates the full case, the story, suspects, locations, weapons, clues and logic relationships, and lays it out on the page automatically. A puzzle page that would take days of writing and design comes out in seconds, with a matching solution page.

✅ Automatic Puzzle Solving And Validation: Every case is checked so the clues lead to one clear, fair answer. That’s the hardest part of detective puzzles to get right by hand, and it’s what keeps readers happy and reviews positive.

✅ Three Ways To Write Your Case Script: Use the free Detective JSON Maker MCP plugin inside ChatGPT, add your own API key to generate scripts inside the workspace, or use BrosAI with built-in access to Claude, OpenAI, Gemini and other models. BrosAI starts you with 500 free credits, enough for hundreds of puzzles.

✅ Edit Every Content Element: Guide the story before the AI writes, then change any name, clue, location or line of the case afterward. You’re the director, so each mystery carries your own voice and theme.

✅ Drag-And-Drop Page Control: Move blocks freely, set margins, change numbering, add pages and show or hide solutions. Undo and redo make experimenting easy, from a single page to a full book.

✅ Print-Ready Book Sizes And Exports: Page sizes and margins are set up for self-publishing, and pages export as PNG or PDF for KDP, Etsy printables or sharing. You go straight from the editor to the upload screen.

✅ 10-Language Support: Create puzzles and scripts in English, French, German, Italian, Spanish, Portuguese, Japanese, Chinese, Korean and Vietnamese. One book idea can become editions for several Amazon marketplaces with the same effort.

✅ Unlimited Puzzle Pages, Training And Updates: Create as many puzzle pages as you like, follow the guided video training from first click to final page, and get future updates included. Dark mode is there for late-night plotting too.

Detective Maker Pricing & Funnel Summary

Detective Maker Front End ($27)

Detective Maker costs $27 as a one-time payment through WarriorPlus during the launch, with lifetime access; after the launch it moves to a subscription. The front end covers automated case creation and layout, content editing, book sizes and margins, the ChatGPT MCP plugin, BrosAI with 500 free credits, 10 languages, unlimited puzzle pages, solving and validation, video training, the publishing kit, the cover guide, the VIP group and the commercial license. Extra BrosAI credits are optional at 7,000 for $15 a month, or you can use the free MCP plugin or your own API key. A 30-day money-back guarantee covers the purchase.

Is it worth it? Building one detective puzzle page by hand can take a week of writing, logic checking and layout, and a freelance puzzle writer would charge well over $27 for a single case. Here, a full case takes minutes and comes out solvable. It’s a natural fit for KDP and Etsy publishers who want a fresh niche with a proven audience. If you’d like to style every component and batch-create cases, the Plus upgrade is the natural next step.

Why Should You Choose Detective Maker?

My Personal Experience With Detective Maker

I had review access about four weeks before launch and used it to publish a cozy detective puzzle book called “The Lantern Street Casebook”, 40 small-town murder mysteries for adults who love Murdle-style puzzles but prefer a gentle, cozy mood. I chose a quiet English village with a bakery, a church and an old inn as the setting, so every case feels like part of one world.

Here’s how the 40 cases of “The Lantern Street Casebook” were organized:

• Cases 1–8 — First Week In Lantern Street: easy cases with three suspects, three weapons and three locations, such as “The Silent Heir” at the old manor and “Poison At The Bake Sale”, each with a short how-to page for new solvers.
• Cases 9–18 — The Harvest Festival: medium cases with four suspects, set across the fairground, the cider barn and the village green, with one red-herring clue per case.
• Cases 19–28 — Winter At The Inn: snowed-in mysteries at the Lantern Inn with four suspects and an extra “motive” column added to the grid using the drag-and-drop editor.
• Cases 29–36 — The Inspector’s Hardest Files: hard cases with five suspects, five weapons and five locations, and longer clue lists that need careful elimination.
• Cases 37–40 — The Final Mystery: a four-part case that ties the whole book together, with the solution to each part unlocking the next.
• Spanish Edition — El Libro De Casos De Lantern Street: the same 40 cases generated in Spanish for Amazon.es and Amazon.com Spanish readers.

Building all 40 cases took me four evenings. I used the free MCP plugin in ChatGPT for most scripts and BrosAI’s free credits for the rest, then spent time renaming a few suspects and rewriting some clue lines so the village characters stayed consistent across the book, which is normal polishing for any series. I followed the cover guide bonus for a vintage map-style cover.

About four weeks after publishing, “The Lantern Street Casebook” had sold around 186 paperbacks across the English and Spanish editions, with English leading, and a 10-case printable version on Etsy sold 42 copies. Together they earned approximately $1,190, and early reviews mention how fair the clues feel, which is exactly what a puzzle book lives on.

• Multilingual publishers: create editions in 10 languages for Amazon marketplaces in Europe and Asia.

Detective Maker opens up one of the most exciting puzzle niches on Amazon, detective deduction books, and removes the week of writing, logic checking and layout each page used to take.
