Looking for a side hustle you can launch with AI? Claude — Anthropic's powerful AI assistant — is quietly helping everyday people build real income streams. From self-publishing novels to selling printable games on Etsy, here are five proven AI business ideas, complete with the exact workflows to replicate them yourself.
1. Murder Mystery Novels on Amazon Kindle
Murder mystery novels are one of the best-kept secrets in self-publishing right now. One recently published indie novel was estimated to be selling up to 108 ebooks per day — and after Kindle fees, the author earns roughly $5.16 per sale. That's over $500 a day from a single book.
Even more impressive: that same author published nine murder mystery novels in two years, with a combined estimated sales rate of 391 novels per day. And her entire social media presence? A Facebook page with around 500 followers.
Why does this work? Murder mysteries are "beach fiction" — short, fun, easy to read on vacation. Avid readers constantly browse for new Kindle releases and buy them regardless of whether they know the author. Claude is exceptionally good at writing this kind of mass-market fiction.
The 6-Step Claude Workflow to Write a Murder Mystery:
- Create a Claude Project — use it to group all your chats and reference files together.
- Brainstorm your twist — tell Claude your theme (e.g. "gardening") and ask it to generate plot twist ideas. Choose the one you like best and save it as a reference document in your project.
- Build a 12-step mystery formula — ask Claude to structure your chosen twist into the classic 12-act detective story format, then upload it to your project.
- Create character profiles — ask Claude to map out the full cast of characters based on your formula and save them as another reference file.
- Create a master outline — ask Claude to combine all your documents into a single chapter-by-chapter story outline.
- Write the book — start a new chat, reference all your documents, and ask Claude to write Chapter 1. Then ask for Chapter 2 in the same chat for consistency. Repeat until done.
Once finished, combine all chapters into a Google Doc, then use Amazon's free Kindle Create software to convert it into a Kindle-ready ebook and upload it to Amazon KDP.
2. Puzzle Books (Logic Grid / Einstein Riddles)
Puzzle books are another passive income goldmine on Amazon — and they go far beyond basic crosswords. One particularly hot niche is logic grid puzzles, also called Einstein Riddles. These present a scenario and a set of clues that readers solve using a grid.
One independent publisher called Unicorn Books sells logic grid puzzles across multiple themes and niches — and their books are estimated to sell 15–16 copies per day each, passively. Combined across their catalog, it adds up to a solid recurring income.
The business model is beautifully hands-off: upload a PDF to Amazon KDP (Kindle Direct Publishing), and every time someone orders a physical copy, Amazon prints and ships it for you, deducting printing costs and paying you the remainder as commission.
How to Make a Logic Grid Puzzle with Claude:
Simply ask Claude to create a print-ready logic grid puzzle around a specific scenario or theme.
For example: "Create a print-ready grid logic puzzle around a locked room murder mystery." Claude will generate both the puzzle and the solution grid, formatted and ready to use.
3. Excel Spreadsheet Dashboards on Etsy
Downloadable spreadsheet templates are booming on Etsy right now. One Etsy store specializing in Excel dashboards has been open for just 2.5 years and has already made over 143,000 sales — enough to become a 7-figure business, according to Etsy research tools.
Their bestsellers include wedding planner dashboards, daily task trackers, and annual budget spreadsheets — products that sell dozens of copies every single day.
The secret weapon? Claude now has a direct integration with Microsoft Excel. It takes less than a minute to install, after which Claude appears as a sidebar widget inside Excel. You can feed it raw data and ask it to build a colorful, functional dashboard complete with graphs — in minutes.
Even if you customize the final product yourself, letting Claude build the base design saves hours of work.
4. Custom Notion Templates (Freelance or Etsy)
Businesses are paying serious money for custom Notion workspaces. On Fiverr, some design agencies are charging an average of $275 per Notion template, with multiple orders in the queue at any given time.
Notion is an AI-powered productivity platform that lets users build custom dashboards, task trackers, planners, and databases. Companies love it — but many don't have the time or skill to build templates from scratch.
The Claude + Notion Workflow:
Come to Claude and describe the type of Notion template you want to build (or that your client has requested).
Ask Claude to generate a detailed Notion AI prompt for it — for example: "Create a Notion AI prompt to build a full dashboard and database system for a dog walking business."
Open a blank Notion page, activate Notion's own AI, paste in Claude's prompt, and select the Claude model as the AI engine.
Notion AI builds the entire template for you — dashboards, linked databases, and all.
Refine using Notion AI (e.g., "Change the stats section into a 2x2 grid") or make manual edits yourself.
The result is a professional, database-connected Notion workspace you can deliver to clients or sell as a digital product.
5. Printable Games on Etsy (Using a Free Canva Trick)
Printable games are a surprisingly popular category on Etsy. Think themed bingo cards, baby shower games, holiday party packs — the kind of PDFs people buy, print at home, and use for parties or family events.
One Etsy store selling printable games has racked up over 200,000 sales in just 3 years. A single emoji-themed baby shower game sells multiple copies every day.
Here's the workflow — including a Canva trick most people don't know about:
The Claude + Canva Printable Game Workflow:
Ask Claude to create a game.
for example: "Create a baby shower 'Guess Who' game and generate it as a PDF." Claude will write the content and produce a formatted PDF.
Refine with Claude — ask it to tweak the design (e.g., remove background colors, adjust spacing).
Upload the PDF to Canva's free PDF converter — this converts Claude's PDF into an editable Canva file. You do not need a paid Canva account for this.
Edit in Canva — swap fonts, adjust text, update styling to make it your own.
Download as a print-ready PDF — use Canva's "Share > Download > PDF Print" option.
List it on Etsy as a digital download.
Final Thoughts
Whether you're looking to publish your first novel, build a passive income catalog on Amazon, or sell digital products on Etsy, Claude offers a surprisingly powerful shortcut. The businesses above aren't theoretical — they're real income streams that real people are building right now, most of them with no large social media following and no prior publishing or design experience.
The tools are accessible, the markets are proven, and the workflows are straightforward. The only thing left is to pick an idea and start.
