AI course builder
Ailurn turns a topic, a PDF, 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 GitHub repo, a docs URL, or drop a PDF if you already have source material. Suggested starts in the product 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. Ask questions in the lesson. Take quizzes. Listen to narration. When the subject has code, run it in the page. When it 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, and audio — all 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
The product
One workspace to plan a course, open lessons, ask, quiz, 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 or a docs URL. Attach notes and PDFs. The outline can follow your source, not a generic syllabus.
A committed path: ordered lessons, progress as you open them, continue where you left off.
A reader for the material. Ask in the lesson. Quizzes and flashcards from what you just studied. Listen when you would rather hear it.
Code runs in the page — Python, JavaScript, SQL, HTML. STEM lessons get labeled models, processes, and worked problems. Not every course is programming.
Public courses live on Explore. Fork one into your workspace if someone already built the path you wanted.
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.”
Drop the file. Paste the URL. 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, Ask, quizzes, and audio live in the same workspace you generated.
Pricing
Every plan is the course builder. Paid plans raise generation caps and extras like Ask, audio, review, and export.

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: reader, Ask, quizzes, and audio.
A prompt in planning chat is enough. You can paste a public GitHub repository or a documentation URL to ground the outline. You can attach notes or PDFs. Explore lists public courses you can fork into your workspace.
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. Sandboxes show up when a lesson has 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. You can Ask questions in the lesson, take a quiz, use flashcards, and listen to narration. Previous / next sit at the bottom. Progress is lessons you have opened.
Yes, when the lesson includes it. Python runs in the browser, plus JavaScript / TypeScript, SQL, and HTML. Nothing to install. Courses that are not about code simply do not run code.
The product is the same workspace. Plans cap how many courses and lessons you can generate, file uploads, and extras like audio, Ask, review, and export — so we can keep building it. See Pricing for the current limits.
Yes. On Plus you can export a course pack as Markdown ZIP, JSON, or HTML. You own the material.
Start for free with no credit card. Pro and Plus are monthly or yearly, with 25% off annual. Cancel from billing settings at any time.
