AI course builder
Ailurn turns a topic, a repo, or a URL into modules and lessons you actually study — finance, design, interviews, math, or code. You create the course. You learn it here.
Pick a starting point, or type below.
Any subject. You name it. Ailurn writes the path.
How it works
Three steps. No marketplace. No waiting for a cohort to start.
01
Open a new course and talk to the planner. A sentence is enough. Paste a public GitHub repo, docs URL, or YouTube link, or attach your own PDF and notes. Suggested starts range from interview prep and design systems to unit economics and linear algebra.
02
Ailurn researches, asks a few questions, then commits modules and ordered lessons. You are not shopping a catalog. You get a path built for the outcome you named.
03
Each lesson is a reader with previous / next, plus Ask, quizzes, flashcards, and audio narration. When a lesson has code, it walks you through running that code in Visual Studio Code. When the subject has structure — anatomy, a process, a worked problem — you get a model next to the prose.
The workspace
Modules on the left. The lesson in the middle. Ask, quiz, flashcards, and audio on the same path.
Lesson 02 · Contribution margin
Contribution margin is price minus variable cost. It is not “growth.” It is not MRR. If this number is thin, every new customer makes the hole deeper. Work the example before you open a spreadsheet at work.
Ask can walk the same numbers. A quiz checks whether you can restate the definition without the lesson open.
Study
One workspace to plan a course, open lessons, test yourself, and practice when the subject needs it.
Describe the outcome. The planner researches and drafts the path before a single lesson is written.
Paste a GitHub repo, docs URL, or YouTube link, or attach PDFs and notes. The outline follows your source, not a generic syllabus.
A committed path: ordered lessons, progress as you open them, continue where you left off.
A distraction-free reader with an in-lesson tutor (Ask), quizzes, flashcards, slides, and audio narration.
When a lesson has code, it walks you through running that code in Visual Studio Code. STEM lessons get labeled models, processes, and worked problems. Not every course is programming.
Public courses live on Explore. Fork any course into your workspace to study it on your own schedule.
Sounds familiar
“Every catalog course assumes a job I do not have and a pace I cannot keep.”
You name the outcome. Ailurn writes the path for that outcome.
“I have a hundred-page PDF and a repo. I need a way through them, not another beginner track.”
Paste the repo or docs URL, or attach the PDF. The course follows your source.
“I want to learn unit economics, not another JavaScript tutorial.”
Finance, design, interviews, math, code — the builder does not care which subject you picked.
“ChatGPT gave me an outline. I still do not have a place to take the course.”
Lessons live in the same workspace you generated, alongside Ask, quizzes, flashcards, and audio.
Every plan is the course builder. Paid plans raise generation caps and extras like Ask, audio, review, slides, file uploads, and export. Also on iOS and Android; Pro is billed separately in each store.

$10/ month
An AI course builder. You describe what you want to learn — any subject — and Ailurn generates a structured course of modules and lessons. You take that course in the same workspace: a lesson reader, with Ask, quizzes, flashcards, and audio.
Paste a public GitHub repo, docs URL, or YouTube link on any plan. Attach PDFs and notes on Pro. Fork a public course into your workspace. Free includes one course; upgrade to Pro if you already have one.
No. Suggested starts in the product include design systems, SaaS unit economics, first-principles thinking, linear algebra, and interview prep — as well as Next.js and AI agents. Code lessons walk you through running the program in Visual Studio Code. STEM models show up when the lesson is a labeled figure, a process, or a worked problem.
Modules of ordered lessons. Each lesson is a reader. Previous / next sit at the bottom. Progress is lessons you have opened, not quiz scores. Unlimited courses, unlimited lesson generation, file uploads, and course-pack export are on Pro.
Yes. When a lesson has code, it walks you through running that code in Visual Studio Code. You install the editor and the language runtime once. Courses that are not about code do not ask you to.
Free includes planning chat with web research, a full outline, 2 AI-generated lessons, and study tools (Ask, quizzes, flashcards, audio, slides). No card. Unlimited courses, unlimited lesson generation, file uploads, and course-pack export are on Pro. See Pricing for the current limits.
You keep the prompts and files you submit. Generated lessons are licensed for personal study. Export a Markdown ZIP, JSON, or HTML pack on Pro.
Ask is an in-lesson tutor grounded in the current lesson — not a citation engine.
Start for free with no credit card. Pro is monthly or yearly, with 20% off annual. Cancel from billing settings at any time. iOS and Android bill Pro separately through the App Store or Google Play.
