Book to Course Claude Skill: Turn Any Book Into Lessons

Use the open-source book to course Claude skill to turn EPUB, PDF or Markdown files into lessons, quizzes and flashcards, then repurpose them with Creator OS.

Creator OS · October 6, 2026 · 8 min read

The book to course Claude skill takes a book you already own in EPUB, PDF, HTML, DOCX or Markdown form and turns it into a beginner-friendly course: lessons, animations, quizzes and flashcards. That matters for creators because a book is the densest source material you will ever own, and up to now there was no clean path from “I read this” to “I published twelve posts about it.” A skill runs inside your AI app, so you point Claude at the file, give it a goal, and get structured output you can then publish through Creator OS to Instagram, TikTok, YouTube, X, LinkedIn, Facebook and Threads.

What the Book to Course Claude Skill Does

A Claude skill is a folder of instructions and reference files that Claude loads when the task matches. The book-to-course skill is built for one job: read a long source document, understand its structure, and emit teaching material aimed at a beginner.

It is not a summarizer. A summary compresses a book into something you read once. A course expands it into something a student works through, in order, with checkpoints. That difference is the whole point. A chapter becomes a lesson. A concept becomes an explanation. A list becomes a quiz. A definition becomes a flashcard.

For creators this is a repurposing engine. If you have written a book, or bought one you are allowed to teach from, the skill is the fastest way to convert that material into a curriculum and a content series at the same time.

Install the Skill and Point It at Your Book

Skills live in a folder your AI app reads. In Claude Code, the standard location is a skills/ directory in your project, and creatoros init installs the Creator OS skills alongside anything else you keep there. Run the install once, then call the skill by describing the task.

npx @creatoros/cli@latest init

# 14 Creator OS skills are installed, alongside the
# book-to-course skill you added to your project

Then the prompt is short. You name the file, the audience and the shape you want.

Use book-to-course on ./manuscript.epub

Audience: beginners who have never run a paid ad.
Output: 10 lessons, each with 1 quiz question and 3 flashcards.
Tone: plain, second person, no jargon.
Save as course.md

That is the whole interaction model. The skill reads the book, works out chapter boundaries from the document structure, and writes the course. Nothing leaves your machine except the parts the model needs to see.

One practical note: run it on one chapter first. Quality varies with how clean the source file is, and a five-minute test on a single chapter tells you more than reading the skill’s own documentation.

Supported Inputs: EPUB, PDF, HTML, DOCX and Markdown

The skill accepts EPUB, PDF, HTML, DOCX and Markdown. Each format has a different failure mode, so choose deliberately.

  • EPUB is usually the best input. Chapters are already separate documents with real headings, so the skill gets structure for free.
  • Markdown is the cleanest overall. If you have your own notes, this is the format to convert them into before running the skill.
  • DOCX works well when the file uses real heading styles rather than bold text pretending to be a heading.
  • HTML is fine if the markup is semantic. Scraped pages full of navigation and ads will pollute the output.
  • PDF is the risky one. Two-column layouts, footnotes and scanned pages all degrade extraction. Check the first ten pages of output before trusting the rest.

If your source is a paper book, do not scan it. Type the chapters you care about into Markdown. Twenty clean pages beat three hundred noisy ones.

What You Get Back: Lessons, Animations, Quizzes and Flashcards

The output is a course, which means several artifact types side by side.

Lessons are the spine. Each one opens with what the reader will be able to do at the end, then teaches it in small steps. Beginner-friendly means the skill assumes no prior context, so a lesson on retargeting starts by explaining what a visitor is.

Quizzes test recall at the end of a lesson. Short, one or two questions, tied to the specific thing just taught.

Flashcards are the spaced-repetition layer. Terms on one side, definitions on the other. Export them to whatever app you use.

Animations are the visual explanations: a sequence, a diagram, a small motion piece that shows how something moves or flows. These are the artifacts you can lift straight into short-form video.

Ask for all four in one pass and you get a pile of raw material. Ask for lessons and quizzes only and you get something you can read in an afternoon. Match the output to the work you actually plan to do with it.

Customize the Output for Your Audience and Brand

The first pass is generic. The second pass is yours. Two prompt additions do most of the work.

First, an audience line. “Beginners who have never run a paid ad” produces different lessons than “agency owners managing five accounts.” Same book, different course.

Second, a voice line. If you have a style guide, paste it in. If you do not, describe your rules in a few sentences: sentence length, whether you use contractions, what you call your reader.

Then constrain the structure. Naming a lesson count, a quiz count per lesson and a flashcard count per lesson gives you predictable output you can format into a template. Unconstrained runs produce uneven courses that are painful to publish.

If you are building the course to sell rather than give away, keep the lessons in a private document until you have decided what is free and what is paid. Creator OS connects to Skool by having you sign in on Skool’s own page and share communities read or read & write, so a paid community version can live there while you seed the free half with public posts. The details are in the Skool docs.

Turn One Book Into a Multi-Post Content Series

This is where the skill stops being a study tool and starts being a publishing pipeline. Every lesson is a post. Every quiz is an engagement prompt. Every flashcard is a carousel slide.

Here is a workflow that takes a book from file to published in one sitting.

  1. Run the skill and save course.md.
  2. Pull the ten lesson titles out as a series plan.
  3. Draft each lesson as a short post with creatoros posts:create.
  4. Check captions against each platform’s limits before scheduling.
  5. Publish the series across the week.
creatoros validate:post-length --text "Lesson 3: what a pixel actually does..."

creatoros posts:create \
  --text "Lesson 3: what a pixel actually does..." \
  --platforms instagram,threads,linkedin \
  --scheduledAt 2026-03-04T14:00:00Z \
  --timezone America/Toronto

Long lessons become articles. Short ones become Reels and Shorts. Quiz questions become polls on X, Threads and LinkedIn, and a poll is one of the easiest ways to find out which lesson to expand next. The animations become the video assets.

For the caption and format differences across networks, the post to every social platform from Claude walkthrough covers the platform rules and the per-network options. If the series leans on Threads, the Threads scheduler post covers multi-post threads. And if you want the same series to go out to a Skool community, creatoros skool:multi-post pushes one post to several communities at once.

Pair It With Other Creator OS Claude Workflows

The book-to-course skill is most valuable when it feeds other workflows rather than standing alone.

Social Agents. The Social Agents harness runs your socials on Creator OS. It interviews you about your brand, then posts, replies to comments and DMs, runs automations and reports into a local dashboard. Run it after the course exists and it can carry the series for you. Start it with npm start creatoros social-agents. The full tool list is in the Social Agents docs.

OPEN VIDEO EDIT. The OPEN VIDEO EDIT skills turn a raw talking-head clip into an animated short with captions, logos, b-roll cards and counters, rendering locally with Python and ffmpeg. Take an animation from the course, record two minutes over it, and you have a lesson video. Skills include fireship-style-short and split-animated-short, and you can watch the whole thing being built on the KevBuildsApps YouTube channel.

Blog and Skool. A lesson with a bit more depth can become a WordPress article through creatoros blog:create, which drafts by default unless you pass --publish. A community version can go out with creatoros skool:multi-post to several communities at once.

To run all of this from your AI app instead of the terminal, add the hosted MCP server at https://mcp.creatoros.ca/mcp. There is nothing to install. In Claude: Settings, Connectors, Add custom connector, paste the URL, sign in and choose read only or read & write. Read-only connections only see read tools and the API refuses writes from them. Tool names include create_post, check_caption_length, skool_multi_post and blog_create_article. The full list lives in the MCP docs.

Limits, Licensing and Quality Checks

Three honest constraints.

Licensing. The skill processes a file. It does not grant you rights to the book. Turning a copyrighted book into a paid course requires permission, a license, or public domain status. Your own book, a book you wrote under contract, or a public domain title are all clean. Anything else needs a lawyer’s answer, not a prompt.

Quality. The skill will produce lessons from a bad source file and will not warn you. Read the first chapter of output. If the structure is wrong, fix the source file, not the prompt.

Scope. A course has to be checked against the book. Ask the skill to cite the chapter for each lesson so you can spot places where the model drifted. If a lesson cannot be traced back to a chapter, cut it.

Do not ship generated quizzes as assessments without reading every question. Wrong answers in a quiz teach the wrong thing, and that is a reputation cost you cannot undo with an edit.

Get Started With Creator OS

The Creator plan is $19.99/month or $59.99/year, with up to 8 connected accounts (7 socials plus Skool). API keys, the MCP server, the CLI and the agent skills are included on every plan, so there is no extra tier to reach the publishing tools. Create an account, connect your platforms, and point the skill at something you have already written.

If you would rather watch it happen first, the walkthroughs are on the KevBuildsApps YouTube channel, including the launch video for the open-source tools. Everything else, including the CLI reference and the platform-specific options, is at creatoros.ca/docs.
