How to sell an Obsidian vault as a digital product

Published 21 September 2026 · 9 min read · by TheFinalVault

A vault is a folder of linked markdown notes that someone opens in Obsidian, in any text editor, or hands to their AI assistant. As a product it has three things going for it: it costs almost nothing to produce, it is delivered as a single zip file, and the buyer owns it outright. This guide covers how to build one that people can actually use, and the mistakes that cost refunds.

When a vault is the right format, and when it isn’t

A vault works for knowledge work: business, marketing, writing, software, productivity, data, studying. The buyer sits at a computer, is comfortable with folders, and wants something to work with, not something to watch.

It is the wrong format when the buyer mostly uses a phone, when the niche is unfamiliar with files (most hobby and consumer niches prefer a PDF or an app), or when the value is in watching you do it — physical technique, a craft, a sport. For those, a PDF guide or a video course fits better.

The anatomy of a vault that sells

Structure is part of the product. A buyer should know where to go in the first minute.

Your_Vault/
├── START.md           ← start here: what it is, how to use it, 3 actions for today
├── AGENTS.md          ← instructions for the buyer's AI assistant
├── 00_MOC.md          ← map of contents linking every note
├── 01_Module_A/       ← lessons with the same structure every time
├── 02_Module_B/
├── 90_Prompts/        ← prompts that run each lesson
├── 95_Templates/      ← fill-in templates
├── 98_Data/           ← tables and figures the AI doesn't have, each with a source
├── CHANGELOG.md       ← versions and what changed
└── LICENCE.md         ← what the buyer may and may not do

START.md is module zero

In this order: what the buyer will have when they finish, how to use the vault (“don’t read it cover to cover, open the map and go to your situation”), three actions that take twenty minutes today, and where to ask questions. Add one operating warning: open the folder with the tool, don’t paste the notes into a chat. It is the most common confusion with this format.

AGENTS.md turns the vault into a program

Many buyers will point Claude, ChatGPT or another agent at the folder. An AGENTS.md tells that assistant what to read first, what to produce, and what not to do — for example, not to invent figures that aren’t in 98_Data. With it, the product isn’t only read, it is executed.

Every lesson with the same shape

When you are here → what to do → data and criteria → common mistakes → checklist → an example → the prompt that runs it. A fixed shape lets the buyer skim, and lets an AI assistant find things reliably.

Writing it with AI without selling mistakes

AI makes the writing fast. It also makes up figures with total confidence. A vault you sell is judged on its facts, so the rule is simple: every number carries its source and the date you checked it, and anything you can’t verify is removed or labelled as unverified.

Before selling, do a critic pass per module: ask an assistant to look only for invented data, contradictions between notes and broken links. Then check the flagged items yourself. One false figure in a paid product is a refund and a bad review.

Also count what you claim. If you advertise “50,000 words”, count words that contain letters or digits; a naive count includes table pipes and horizontal rules and can inflate the total by 15 to 20 percent.

Packaging: the details that break on the buyer’s machine

• Clean the folder. Remove .obsidian/workspace.json and caches. Obsidian creates its settings folder on first open.
• Keep the zip small. Under 50 MB. Link to videos instead of embedding them.
• Watch non-ASCII file names. A zip made without the UTF-8 file-name flag shows accented names as garbage on Windows (“AQU├ì” instead of “AQUÍ”). Build the zip with a tool that sets the flag, or keep names ASCII, and test on Windows and macOS.
• Add an HTML entry file. A START HERE.html next to the zip opens in any browser, so someone who has never installed Obsidian still knows what to do next.
• Version it. Product_v1.0.zip plus a changelog. Updates are your reason to contact buyers again, and the reason “lifetime updates” on your page is true.

Where to sell it

Anything that delivers a file will do. What changes is what each platform keeps. For a single sale from an EU customer with no affiliate, approximate net from every 100 euros (figures last verified on 13 September 2026):

The full comparison, with sources and the cases where each one wins, is in Whop vs Gumroad vs Stan Store fees.

How to price a vault

If you launch at a lower price, tie the increase to something verifiable — a number of buyers or a new edition — rather than a countdown. And show the price the customer will actually pay: if your platform adds VAT on top at checkout, a €28 page becomes a €33.88 charge, which reads as a bait-and-switch. On Whop this is a single tax setting (tax included vs. exclusive).

The licence: decide it before you sell

Markdown is trivial to copy, so the licence is what defines what the buyer is paying for. The usual options:

• Personal use. The buyer can use and adapt the vault for their own work and their clients, but not redistribute it. The most common choice.
• Adapt and sell. The buyer can transform the material and sell products of their own built from it, but not the vault as delivered, and cannot pass resale rights on. It is more valuable to the buyer and still protects your own version.
• Full resale rights (PLR/MRR). The buyer can resell it as is. Within weeks there will be identical copies at lower prices, including yours.

Whatever you choose, put it in a LICENCE.md inside the zip, on your sales page and in the terms accepted at checkout, with the same wording in all three.

If you sell to EU customers

Consumers in the EU normally have 14 days to withdraw from an online purchase. For digital content delivered immediately, that right can be waived, but only if the buyer expressly consents to immediate delivery and acknowledges losing the right — typically a checkbox at checkout (in Spain, article 103.m of Royal Legislative Decree 1/2007). Don’t also advertise a “14-day money-back guarantee” that contradicts the waiver; promise only what you will honour, such as resending or refunding a file that doesn’t work. And never promise income: it is misleading, and ad platforms reject it.

This is general information, not legal advice. Check the rules that apply to you.
