Coding Playground Beside Every Lesson
Watch. Code. Run. Without leaving the lesson.
An in-browser coding editor that sits beside your video lessons and course modules. Students write and run code in the language the course teaches while the concept is on screen, and the lecture assistant can read the code in the editor and suggest fixes as a diff — no separate IDE, install or tool switch.
How it works
- 1Open the lessonThe editor sits beside the video or reading.
- 2Write and runStudents run code in the browser as the concept is taught.
- 3Ask about the codeThe lecture assistant reads the editor and suggests fixes as a diff.
★ Code, video and checkpoints live in one lesson: instructors place checkpoint quizzes at set moments in the video, and the lecture assistant can read the code a student just wrote.
What Coding Playground Beside Every Lesson does for your institution
Learn by doing, not just watching
Students run real code the moment a concept is taught — no context switch to a separate tool.
Zero setup for learners
No local installs, compilers or environment configuration — the editor runs entirely in the browser.
Help that reads the code
The lecture assistant reads what is in the editor and proposes changes as a diff the student accepts — never over their work.
Checkpoints at the right moment
Instructors place checkpoint quizzes at set timestamps in the video, so understanding is checked where the concept is taught.
