Why text?

Reading beats watching.
Here's why.

Video is easy to start and hard to finish. Text is faster to consume, easier to reference, and simpler to keep accurate. This platform is built around that insight.

No Videos. No Waiting.

Skip straight to the knowledge. No buffering, no scrubbing. Pure, focused text — ready at your pace.

Fully Searchable

Every word in every lesson is indexed. Find exactly what you need in seconds — across every course.

Written by Experts

Anyone with real expertise can contribute a course — on any subject. The community sets the quality bar.

Any Subject

Programming, photography, history, finance — no topic limits. If it can be taught through text, it belongs here.

Distraction-Free

A reading experience designed for deep focus. No autoplay, no algorithm, no noise — just you and the lesson.

Always Up to Date

Text is trivial to edit. Contributors open a PR to fix, expand, or translate any lesson — instantly live.

Common questions

Frequently asked
questions

What is Ereyle?

Ereyle is an open-source platform for text-based courses on any subject. It's built and maintained by the community — anyone with expertise can publish a course, and anyone in the world can read it for free.

Why text instead of video?

Text is faster to read than video is to watch, infinitely searchable, trivial to update, and works on any connection speed. Video courses are easy to start and hard to finish — written lessons are the opposite.

Is it really free?

Yes, and always will be. Every course on this platform is free to read. No paywalls, no subscriptions, no upsells. The platform itself is MIT-licensed open source.

Do I need an account to read?

No account needed to read any course. Creating an account lets you track your progress across lessons and contributes to a public profile if you write courses.

What subjects can be published here?

Any subject that can be taught through structured text. Programming, writing, photography, finance, music, law, history, science — there are no restrictions. The only requirement is that the content is original, accurate, and well-structured.

How do I contribute a course?

Read the Contributing Guide, fork the repository on GitHub, create a course JSON file and your lesson MDX files, then open a pull request. The maintainers will review and merge it. No prior open-source experience required.
