Lumen gives every instructor their own course site on its own subdomain — publish structured lessons, control exactly how access unlocks, and watch learners make real progress to a certificate.
No card to start · Two live demo schools to click through
Upload straight to Mux from the browser — your video never touches a server. Playback is paywalled at the CDN with signed tokens minted only after access passes, captions are generated automatically, and learners resume right where they left off.
Write text lessons in a proper editor, attach downloadable files, and mix media within a course.
Set a pass mark and attempts. Passing marks the lesson complete and can unlock the next one.
One-time purchase, all-access membership, free, or coupon codes — all on Stripe, in integer cents.
Free previews, read-time drip that respects the learner's timezone, and sequential prerequisites.
Grounded in your lessons, with citations — and an honest “not covered here” when it doesn't know.
Finish a course and Lumen issues a PDF certificate with a public verification page — no fakes.
Every school gets its own subdomain, logo, and accent color. Learners never see another brand.
Most course platforms bolt on a chatbot that confidently invents answers. Lumen's tutor retrieves the actual lesson content first — it cites where each answer came from, and when the course doesn't cover something, it says so instead of guessing.
Aim for roughly 45–75 characters per line. Longer lines tire the eye; shorter ones break reading rhythm.
Type fundamentals
Sign up and your school is live on its own subdomain in seconds.
Add video, text, files, and quizzes. Drag modules and lessons into order.
Free preview, one-time price or membership, drip, and prerequisites.
They make their way through, and earn a verifiable certificate at the end.
Whether learners buy one course or subscribe for the whole catalog, it's the same access engine underneath — the pricing model is just a setting. Two demo schools run on this one codebase. Click through both:
Learners sign up per school to enroll and track progress. Anyone can browse the catalog and watch free-preview lessons without an account.
Sell a course one-time, give it away free, or run an all-access membership for your whole catalog. You can also issue coupon codes. Payments run through Stripe.
Video is hosted on Mux. Playback is paywalled at the CDN with signed tokens that are only minted after a learner's access is verified — the raw playback ID is useless on its own.
Yes. Lessons can unlock a set number of days after enrollment (computed in the learner's timezone) and can require an earlier lesson or quiz to be completed first.
It answers only from your course's lessons and cites them. When something isn't covered, it says so instead of inventing an answer. You can also draft quizzes from your lessons with it.
It's a portfolio project — a complete, working LMS. The two demo schools linked above are live; click through them to see the learner experience end to end.
Publish your first course, set how it unlocks, and let learners make their way through.
