Product

Build a course. Take it in the same workspace.

Plan from a prompt, a PDF, a repo, or a URL. Open lessons. Ask, quiz, listen, and practice in the same workspace.

How it works

You create the course. Then you take it.

Three steps. No marketplace. No waiting for a cohort to start.

  1. 01

    Say what you want to learn

    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.

  2. 02

    Get a structured course

    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.

  3. 03

    Learn in the workspace

    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

A course you own, not a video you rent.

Modules on the left. The lesson in the middle. Ask, quiz, and audio — all on the same path.

Lesson 02 · Contribution margin

What is left after you deliver one more unit.

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

If CAC is $180 and contribution per month is $45, how many months to pay back?

Four months — if churn stays still. Run the worked problem in the lesson if you want the algebra on the page.

The product

Everything you need to build a course and take it.

One workspace to plan a course, open lessons, ask, quiz, and practice when the subject needs it.

  • Plan in chat

    Describe the outcome. The planner researches and drafts the path before a single lesson is written.

  • Ground it in your material

    Paste a GitHub repo or a docs URL. Attach notes and PDFs. The outline can follow your source, not a generic syllabus.

  • Modules and lessons

    A committed path: ordered lessons, progress as you open them, continue where you left off.

  • Learn in the lesson

    A reader for the material. Ask in the lesson. Quizzes and flashcards from what you just studied. Listen when you would rather hear it.

  • Practice when the subject needs it

    Code runs in the page — Python, JavaScript, SQL, HTML. STEM lessons get labeled models, processes, and worked problems. Not every course is programming.

  • Explore and fork

    Public courses live on Explore. Fork one into your workspace if someone already built the path you wanted.

Start

Name a subject. Leave with a course.

Design, finance, math, interviews, or code. You create it. You learn it here.
